NCC Limited partners with CDE Asia for Samruddhi Mahamarg Project

15 October 2022

Led by Maharashtra State Road Development Corporation (MSRDC), Samruddhi Mahamarg or Mumbai-Nagpur Expressway, India’s longest Greenfield Road project, connecting Nagpur and Mumbai aims to minimize the commute time between the two cities from 14 hours to 8 hours. It is a planned 6-lane wide (expandable to 8), 701 km long access-controlled expressway, comprising a total of 16 packages. Package 3 of the project has been awarded to NCC Limited. Supposedly the longest package in the entire project with a scope of 73.367 km, it will connect the villages Ashta and Wadhona Ramnath in the Amravati district.

NCC Limited, with more than 4 decades of operations, has a legacy of contributing to prominent urban infrastructure projects with uncompromising standards.

Even before receiving the official documents for the allotted package, NCC Limited approached CDE Asia, the pioneer in the wet processing equipment for M-Sand for a partnership on this gigantic project. After their initial meeting with the CDE Asia officials, Mr. Krishnam Raju, General Manager of NCC visited one of their clients’ site in Karnataka, which further boosted his confidence in the CDE Asia plant.

Understanding the importance and immensity of the project at hand, we aimed to secure the client’s trust by introducing him to the finest product from our flagship Combo platform – Combo X70.

Best Sand Filter System

Sand filters are utilized as a stage in the water treatment cycle of water purging.

There are three principle types; quick (gravity) sand filters, upward stream sand filters and moderate sand filters. Each of the three techniques are utilized broadly in the water business all through the world. Sandfilteranlage The initial two

require the utilization of flocculant synthetic substances to work viably while moderate sand filters can deliver excellent water with microorganisms expulsion from 90% to >99% (contingent upon the strains), taste and

scent without the requirement for compound aids. Sand filters can, aside from being utilized in water treatment plants, be utilized for water filtration in particular families as they use materials which are accessible for most

people.

The historical backdrop of division methods comes to far back, as filter materials were at that point being used during old periods. Surges and genista plants were utilized to fill sieving vessels that isolated strong and fluid

materials. The Egyptians additionally utilized permeable earth vessels to filter drinking water, wine and other liquids.

A sand bed filter is a sort of profundity filter. Comprehensively, there are two sorts of filters for isolating particulate solids from liquids:

Surface filters, where particulates are caught on a porous surface

Profundity filters, where particulates are caught inside a permeable assemblage of material.

Likewise, there are detached and dynamic gadgets for causing strong fluid partition, for example, settling tanks, self-cleaning screen filters, hydrocyclones and centrifuges.

There are a few sorts of profundity filters, some utilizing stringy material and others utilizing granular materials. Sand bed filters are an illustration of a granular free media profundity filter. They are normally used to

isolate limited quantities (<10 parts per million or <10 g for each cubic meter) of fine solids (<100 micrometers) from watery solutions. :302–303 likewise, they are typically used to clean the liquid as opposed to catch the

solids as an important material. In this way they discover the vast majority of their uses in fluid gushing (wastewater) treatment.

Particulate solids catch systems

Sand bed filters work by giving the particulate solids numerous occasions to be caught on the outside of a sand grain. As liquid courses through the permeable sand along a convoluted course, the particulates approach sand

grains. They can be caught by one of a few components:

Direct impact

Van der Waals or London power fascination

Surface charge fascination

Diffusion

Moreover, particulate solids can be kept from being caught by surface charge shock if the surface charge of the sand is of a similar sign (positive or negative) as that of the particulate strong. Moreover, it is conceivable to

unstick caught particulates despite the fact that they might be re-caught at a more noteworthy profundity inside the bed. At long last, a sand grain that is as of now debased with particulate solids may turn out to be more

alluring or repulse expansion particulate solids. This can happen if by holding fast to the sand grain the particulate loses surface charge and gets alluring to extra particulates or the inverse and surface charge is held repulsing

further particulates from the sand grain.

In certain applications it is important to pre-treat the gushing streaming into a sand bed to guarantee that the particulate solids can be caught. This can be accomplished by one of a few strategies:

Changing the surface charge on the particles and the sand by changing the pH

Coagulation – adding little, exceptionally charged cations (aluminum 3+ or calcium 2+ are normally utilized)

Flocculation – adding modest quantities of charge polymer chains which either structure a scaffold between the particulate solids (making them greater) or between the particulate solids and the sand.

Working systems

They can be worked either with upward streaming liquids or descending streaming liquids the last being substantially more normal. For descending streaming gadgets the liquid can stream under tension or by gravity alone.

Weight sand bed filters will in general be utilized in modern applications and regularly alluded to as fast sand bed filters. Gravity took care of units are utilized in water decontamination particularly drinking water and

these filters have discovered wide use in agricultural nations (slow sand filters).

Generally, there are a few classes of sand bed filter:

fast (gravity) sand filters

fast (pressure) sand bed filters

upflow sand filters

slow sand filters

The sketch shows the overall structure of a fast weight sand filter. The filter sand occupies most room of the chamber. It sits either on a spout floor or on top of a seepage framework which permits the filtered water to exit.

The pre-treated crude water enters the filter chamber on the top, moves through the filter medium and the emanating channels through the seepage framework in the lower part. Enormous cycle plants have likewise a

framework actualized to equally disperse the crude water to the filter. Furthermore, a circulation framework controlling the wind current is generally included. It permits a consistent air and water appropriation and forestalls

too high water streams in explicit zones. A normal grain conveyance exits due to the successive discharging. Grains with more modest breadth are prevailing in the upper piece of the sand layer while coarse grain rules in the

lower parts.

Two cycles impacting the usefulness of a filter are maturing and recovery.

Toward the start of another filter run, the filter proficiency increments all the while with the quantity of caught particles in the medium. This cycle is called filter maturing. During filter aging the emanating probably won’t

meet quality measures and should be reinjected at past strides in the plant. Regeneration strategies permit the reuse of the filter medium. Amassed solids from the filter bed are removed. During discharging, water (and air) is

siphoned in reverse through the filter framework. Discharge water may somewhat be reinjected before the filter cycle and created sewage should be disposed of. The discharging time is dictated by either the turbidity esteem

behind the filter, which should not surpass a set edge, or by the head misfortune across the filter medium, which should likewise not surpass a specific worth.

Quick weight sand bed filter plan

More modest sand grains give more surface region and along these lines a higher disinfecting of the bay water, yet it likewise requires all the more siphoning energy to drive the liquid through the bed. A trade off is that

most quick weight sand bed filters use grains in the reach 0.6 to 1.2 mm despite the fact that for expert applications different sizes might be indicated. Bigger feed particles (>100 micrometers) will in general impede the

pores of the bed and transform it into a surface filter that blinds quickly. Bigger sand grains can be utilized to conquer this issue, yet on the off chance that huge measures of huge solids are in the feed they should be

eliminated upstream of the sand bed filter by a cycle, for example, settling. :302–303

The profundity of the sand bed is prescribed to be around 0.6–1.8 m (2–6 ft) paying little heed to the application. This is connected to the most extreme throughput examined below. :302–303

Direction on the plan of quick sand bed filters recommends that they should be worked with a greatest stream pace of 9 m3/m2/hr (220 US lady/ft2/hr). Using the necessary throughput and the most extreme stream rate,

the necessary territory of the bed can be determined.

The last key plan point is to be certain that the liquid is appropriately dispersed across the bed and that there are no favored liquid ways where the sand might be washed away and the filter be undermined.

Fast weight sand bed filters are regularly worked with a feed weight of 2 to 5 bar(a) (28 to 70 psi(a)). The weight drop across a spotless sand bed is normally low. It works as particulate solids are caught on the bed.

Particulate solids are not caught consistently with profundity, more are caught higher up with bed with the fixation angle rotting exponentially. :302–303

This filter type will catch particles down to little sizes, and doesn’t have a genuine cut off size beneath which particles will consistently pass. The state of the filter molecule size-proficiency bend is a U-shape with high

paces of molecule catch for the littlest and biggest particles with a plunge in the middle of for fair sized particles.

The development of particulate solids causes an expansion in the weight lost across the bed for a given stream rate. For a gravity took care of bed when the weight accessible is consistent, the stream rate will fall. At the

point when the weight misfortune or stream is inadmissible and the filter isn’t working adequately any more, the bed is discharged to eliminate the aggregated particles. For a pressurized fast sand bed filter this happens when

the weight drop is around 0.5 bar. The discharge liquid is siphoned in reverse through the bed until it is fluidized and has extended by up to about 30% (the sand grains begin to combine and as they rub they drive off the

particulate solids). The more modest particulate solids are washed away with the discharge liquid and caught as a rule in a settling tank. The liquid stream needed to fluidize the bed is ordinarily 3 to 10 m3/m2/hr yet not

run for long (a couple minutes). :224–235 Small measures of sand can be lost in the discharging cycle and the bed may should be bested up occasionally.

kaolin processing plant Processing line for kaolin

Introduction of main processing technology of kaolin: Kaolin processing technology generally includes beneficiation purification, ultra-fine crushing, calcination and surface modification. The original kaolin ore contains kaolinite minerals as the main components, and there are small amounts of montmorillonite, illite, diaspore, quartz, feldspar, mica and iron minerals (limonite, hematite, diamond) Iron ore, pyrite, etc.), titanium oxides (ilmenite, rutile, etc.), organic matter (plant fiber, organic peat, coal) and other impurities. As a mineral filler application, it must be beneficiated and purified. The processing technology of kaolin depends on the type of ore. Different beneficiation and purification processes are adopted for soft kaolin, sandy kaolin and hard kaolin (kaolinite). Dry and wet separation are the two main processes of the kaolin beneficiation process. The dry separation process is used to process kaolin ore with high whiteness and low grit content. It is easy to operate and saves costs. The raw kaolin ore is crushed in a crusher, and then the kaolin concentrate can be obtained by grinding in a Raymond mill. Wet kaolin beneficiation process is used to process complex kaolin ore. Wet beneficiation process uses high gradient magnetic separation, foam flotation and selective flocculant to make full use of kaolin mineral resources. Main production process of kaolin: 1.pounding The raw ore is added with water and dispersant according to the set concentration requirements, and is made into pulp in a mixer or a tamping machine. The purpose of pulping is to disperse kaolin and separate it from sandy minerals and plant impurities in order to prepare a slurry of suitable concentration for the next process. 2. Spiral classifier to remove coarse sand The raw particles of kaolin clay such as quartz, feldspar, mica and other impurities have coarser particle sizes, generally larger than 325 mesh, while the particles of kaolin have finer particle sizes, mainly concentrated in -2μm. A spiral classifier can remove most of the quartz and feldspar coarse sand. 3. Sorting of hydrocyclone The hydrocyclone is used for separation. The operation is to remove kaolin fine sand (fine-grained quartz, feldspar and other impurities). Generally, hydrocyclones with different diameters such as Ø75, Ø50, and Ø25 are used for multiple sorting. 4. Classification of horizontal spiral centrifuge The horizontal spiral centrifuge is used for classification, and the process parameters (such as separation factor) can be adjusted according to different materials to keep the product quality stable. At present, domestic kaolin beneficiation also adopts hydrocyclone for selective classification, but due to the influence of flow and pressure changes, the product quality is difficult to stabilize at -2μm accounting for more than 90%, and the classification efficiency is not as good as horizontal spiral centrifugal classifiers. 5. Magnetic separation In order to obtain high-quality or high-quality kaolin, in most cases, strong magnetic separation or high gradient magnetic separation, chemical bleaching, even flotation and selective flocculation are required. The dyed mineral impurities in kaolin, such as limonite, hematite, siderite, pyrite, anatase, rutile, etc., have weak magnetic properties, so the kaolinite after sand removal can be further used strong magnetic separator or high gradient The magnetic separator performs magnetic separation. Since most of the iron and titanium minerals in kaolin are embedded with finer particle size, the removal rate of strong magnetic separation is generally not high. Therefore, most of the industries currently use high gradient magnetic separators for magnetic separation of kaolin. In addition, superconducting magnetic separators with better performance have also been used for the magnetic separation and iron removal of kaolin. This magnetic separator not only further improves the strength of the magnetic field, but also obtains high-quality high-quality kaolin and reduces energy consumption. If the whiteness index of kaolin after magnetic separation still cannot meet the requirements of high-quality kaolin, chemical bleaching is generally adopted. The special magnetic separator for washing kaolin is a wet strong magnetic separator. The magnetic strength is up to 16000GS. It can remove the regenerated iron in the kaolin during the kaolin grinding process to improve the whiteness. And other weak magnetic substances. 6. Chemical bleaching The chemical bleaching of kaolin is often related to the use performance of kaolin and the impurities contained. The main impurities affecting the use performance of kaolin are iron minerals, titanium minerals and organic matter. Commonly used chemical bleaching includes reduction method, oxidation method, oxidation-reduction combined bleaching method, acid leaching treatment method, etc. 7. Pressure filter process Using high-pressure slurry feeding to improve productivity, ensure product moisture is less than 32 to 35%, save energy consumption and improve working environment. 8. Drying process Powerful drying can be used. Kaolin powder specifications: The specifications of kaolin powder include 100 mesh, 200 mesh, 325 mesh, 800 mesh, 1200 mesh, 2000 mesh, 2500 mesh, 3000 mesh, etc. What kind of equipment is needed to process kaolin ore? It is mainly to determine the finished product according to the use The fineness range belongs to coarse crushing or fine crushing. The equipment used for coarse crushing between 50~325mm is Raymond grinding equipment or ultrafine ring roller mill. The fine crushing is divided into 325~2500 mesh. The equipment is micro-powder grinding equipment such as kaolin powder ultra-fine vertical mill, which can determine which production line is used according to the fineness of the finished product. Regardless of the coarse crushing production line or fine crushing production line, the entire production line includes the crusher and the milling process. For the powder processing of attapulgite, it can be used directly because of its small size. Read the full article

Sand washing plant process

Sand washing plant process is applied for washing sand, reycling fines and reusing most part of muddy water used during the process. The sand washing process can be widely used in all kinds of sand and gravels, also can be used in mines to process all kinds of tailings. Especially for some arid sites.

1. Sand and gravels fed into washing tank of sand washing machine with water by chute. Then is rubbed to washing to remove the impurities mixed into sand and gravels when impeller rotating. Then the washed sand is fed onto dewatering screen to dewater.

2. The overflow of washing machine be discharged into tail water collecting tank through pipe, then is driven into separator by slurry pump to be separated by hydrocyclone. After recycling, 0.074-3mm fine sand is discharged to dewatering screen and mixed into coarse sand uniformly to dehydrate.

3. At the same time, the sediment suspended content is under 5% processed by separator, discharged into tailing water tank, then is pumped into thickener for mud-water separation. The thickener treats about 80% of muddy water into clean water, then directly enters clear water pool through overflow port.

4. Concentrated mud is pumped into chamber press filter from the bottom of thickener, then be pressed into mud cake and realized dry pile. These dry mud cake can as landfill or develop other uses. After pressing process, clean water is discharged to clear water tank to realize the reuse of clean water and zero discharge of entire process.

5. Stones and sand are effectively screened, washed and dewatered in this plant, and muddy water can be recycled use. Lots of avantages of this entire production line has: excellent continuous working performance, convenient maintenance, long service life, easy movement and excellent effects. At the same time, it save resources, reduce water consumption, and ensures no pollution and meets environmental protection requirements.
