Govt bids to set up cement plants near thermal power plants

In order to ensure complete utilization of thermal fly ash from power plants, an expert panel of the Union environment ministry has decided to form a multi-disciplinary committee to examine the possibility of setting up cement plants along with such plants.
It came after the National Green Tribunal (NGT) in January 2017 directed the Union ministry of environment, forest and climate change (MoEFCC) to examine the feasibility of setting up captive Cement Plants near thermal power plants either by project proponents themselves or by joint venture for effective utilization of fly ash generated from power plants.
The expert committee, during its meeting, noted that cement plants require nearly 70-80% of limestone for manufacturing clinker which is grinded for making cement.
According to surveys, every year, millions of tonnes of fly ash is generated across India and this prompted the MoEFCC in 1999, 2003, 2009 and in 2016 to issue directions for its proper use and disposal, mandating it for use in building material and in construction activities like road building.
As per various studies, only about 50-60% of the total fly ash generated by the power sector is being utilised. In 2015, about 180 million tonnes of fly ash was produced across India and by 2025, it is estimated to reach 300 million tonnes a year. With that, utilization of all the fly ash being generated is going to become tougher.
The unutilized fly ash is dumped into poorly designed and maintained ash ponds and it is estimated that about a billion tonne of this toxic ash lies dumped in these ponds, polluting land, air and water.

Cement Plant Process: Ashoka Group






What is Cement 
Cement  is a fine powder which sets after a few hours when mixed with water, and then hardens in a few days into a solid, strong material. Cement is mainly used to bind fine sand and coarse aggregates together in concrete.  Cement is a hydraulic binder, i.e. it hardens when water is added.

Lets Understand the Cement Plant Process

During the cement plant's cement manufacturing process there are several steps and procedures where mainly includes seven steps and these are following:
  • Preparation of Raw Material
  • Raw Material Homogenization
  • Preheating And Precalcining
  • Burning Cement Clinker
  • Cement Grinding
  • Cement Packing And Storage


At cement plant process is to broken and crushing of raw material, like limestone, iron ore, clay and coal etc so crusher part is very important in cement plants, Limestone is the key raw material for cement creation, each producing a ton of clinker required near about 1.25 tons of limestone, around 80% of raw material required for cement production is limestone. Machines and material handling equipment for cement plant should capable for crushing and equipment required like jaw crusher, impact crusher, Ashoka Cement Plants: manufacturing hummer crusher also to give best output of raw material.

The raw materials are delivered in bulk, crushed and homogenized into a mixture which is fed into a rotary kiln. This is an enormous rotating pipe of 60 to 90 m long and up to 6 m in diameter. This huge kiln is heated by a 2000°C flame inside of it. The kiln is slightly inclined to allow for the materials to slowly reach the other end, where it is quickly cooled to 100-200°C. 


We know requirement of quality cement process, our rotary kiln cylinder vessel slowly rotates at .5 to 4.5 revolutions per minute to allow the raw materials and at last ground coal is fed for the firing end of the kiln exactly where its burned to create a temperature of more than 2,000°C.

The series of chemical reactions between calcium and silicon dioxide compounds form the primary constituents of cement i.e., calcium silicate. Kiln is heating up from the exit side by the use of natural gas and coal. When material reaches the lower part of the kiln, it forms the shape of clinker.
Kiln Mills
After passing out from the kiln, clinkers are cooled by mean of forced air. Clinker released the absorb heat and cool down to lower temperature. Released heat by clinker is reused by recirculating it back to the kiln. This too saves energy.

There is a horizontal filled with steel balls. Clinker reach in this rotating drum after cooling. Here, steel balls tumble and crush the clinker into a very fine powder. This fine powder is considered as cement. During grinding gypsum is also added to the mix in small percentage that controls the setting of cement.
Material is directly conveyed to the silos (silos are the large storage tanks of cement) from the grinding mills. Further, it is packed to about 20-40 kg bags. Only a small percent of cement is packed in the bags only for those customers whom need is very small. The remaining cement is shipped in bulk quantities by mean of trucks, rails or ships.

Ball Mill & Kiln Shells Manfacturers in India

The Ball mill is a key piece of equipment for grinding crushed materials and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc. as well as for ore dressing of both ferrous and non-ferrous metals. The ball mill can grind various ores and other materials either wet or dry. There are two kinds of ball mill, grate type and overall type due to different ways of discharging material. There are many types of grinding media suitable for use in a ball mill, each material having its own specific properties and advantages. Ball mill is suitable for both batch and continuous operation, similarly it is suitable for open as well as closed circuit grinding and is applicable for materials of all degrees of hardness.

We Ashoka Group manufacture and supply all type of Material Handling Equipment ,Cement Plant Equipment,Sugar Plant Equipment and many more equipment for heavy industries like Sugar Plant, Cement Plant, Rotary kiln plant and VSK Cement Plant. Bucket Elevators are used to lift loose bulk material through the use of moving buckets attached by a chain or belt.
We are the leading manufacturers and suppliers of industrial equipment like shrouded ball mill used in various industries. Our Ball Mills are suitable for cement plants.There are three types of ball mill manufacturing:
1.Raw materials mills
2.cement (clinker)mill
3.Coal mill
Uses / Applications / Features :
  • Reasonable design and strict manufacture .
  • Strong to grind .
  • Better the ventilating .
  • High fineness .
  • High production capacity and stable to run
  • easy to operate with high performance life

Cement Plant Machinery Manufacturers : Ball Mill Manufacturers for Cement Plants: Ball Mill - Ashoka Group Ashoka Group manufacture and supply all type of cement plants specially rotary kiln plants, clinker plants ...

Ball Mill Manufacturers for Cement Plants


Ball Mill - Ashoka Group

Ashoka Group manufacture and supply all type of cement plants specially rotary kiln plants, clinker plants and other vertical shaft kilns. We manufacturing high quality durable Ball Mills for cement plants. Ball mill is a horizontal cylinder partly filled with steel balls or some other shapes also these balls or particles rotates on the axis. Material that fed through the mill is crushed by impact and ground by attrition between  these balls. 

These ball mills are usually made of high chromium steel and usually divided into at least two chambers that depends upon feed input size presently mill installed with roller press are usually single chambered. ball mills are designed and developed in different sizes and can use different material also. We at Ashoka Group fabricate high quality ball mills that work in all condition and all different sizes of grinding media. Large ball useful to inlet crush clinkers nodules. Diameter is in the range of 15 - 40 mm sizes.

Its not recommended that a large mill work good, its always suggested by the technical monitoring tean because ball diameter has some range, two chamber mill the media in the second chamber are typically in the suggested range.
