Being one of the basic elements for setting up strong and healthy infrastructure, cement plays a crucial role in economic development of any country. Having more than a hundred and fifty years history, it has been used extensively in construction of anything, from a small building to a mammoth multi purpose project. This paper deals with a case study of a reputed process industry, some changes in the process has been suggested, which leads to reduction in labor cost and production cost.

There are three types of processes to form cement - the wet, semi-dry and dry processes. In the wet/semi-dry process, raw material is produced by mixing limestone and water (called slurry) and blending it with soft clay. In the dry process technology, crushed limestone and raw materials are ground and mixed together without the addition of water.

The dry and semi-wet processes are more fuel-efficient. The wet process requires 0.28 tonnes of coal and 110 kWh of power to manufacture one tonne of cement, whereas the dry process requires only 0.18 tonnes of coal and 100 kWh of power.

The manufacturing process of cement consists of mixing, drying and grinding of limestone, clay and silica into a composite mass. In this process will need some cement crusher machines, such as jaw crusher, impact crusher,VSI crusher and so on.The mixture is then heated and burnt in a pre-heater and kiln to be cooled in an air-cooling system to form clinker, which is the semi-finished form. This clinker is cooled by air and subsequently ground with gypsum to form cement.

The grate cooler is a quenching type cement cooler apply for the cement manufacturing plant. According to the movement mode of the grate, the grate cooler can be divided into three types, rotary type, vibrating type, and push-type grate cooler, with the development of cooler technology, push-type grate cooler is considered as the most common clinker cooler in the cement production line.

The grate cooler is composed of upper case, lower case, grate bed, grate bed transmission, supporting device for grate bed, clinker crusher, funnel, drag chain conveyor, automatic lubricator, cooling air unit, and etc.

The grate plate and grate bed structure are the most important parts of the grate cooler, which decide the thickness of the feed layer, yield per unit of grate bed, and working efficiency of the air supply system and heat recovery. So the development of a grate cooler mainly refers to the moderation of the grate plate and grate bed.

The clinker temperature is an important indicator of the grate cooler performance, which reflects the cooling efficiency of the grate cooler, and also creates conditions for the conveyer, storage, and cement grinding of clinker in subsequent processes. At present, the cooler manufacturers guaranteed value for this temperature is 65+ ambient temperature. Thirdly, the key is how to accelerate the cooling rate of the clinker.

After the heat exchange between the cold air and the clinker at 1200, the clinker cooling heat was recovered. According to different heat transfer efficiency, the temperature of secondary air and tertiary air is between 800~1100. Therefore, the heavy material layer above 800mm should be maintained in the high-temperature section of the grate cooler. The corresponding blower under the grate plate must be a high-pressure blower. Moreover, there should be 6-9 rows of inclined fixed grate plate here, in order to improve the heat recovery and material distribution on the grate bed.

Among the three tasks, increasing the temperature of secondary air and tertiary air is definitely the result of decreasing the clinker temperature, but not any measure to reduce the clinker temperature can increase the secondary air and tertiary air temperature, so the temperature of the clinker discharged from grate cooler should be controlled. When the cooling air of the grate cooler is increased unlimitedly; Or blindly increase the use of air in the high-temperature section; Or increase the use of air in the low-temperature section, although the temperature of the clinker discharged from the grate cooler decreases, it will not increase the temperature of the secondary air and tertiary air into the kiln, but on the contrary, it will increase the temperature of waste gas of grate cooler. At this point, the clinker heat consumption does not decrease, but increases the power consumption of the exhaust fan, and also increases the burden of the dust collector.

How does the grate cooler work? The high-temperature clinker falls into the grate bed from the kiln and is pushed along the full length of the grate bed by the reciprocating grate plate, forming a materials bed of certain thickness. The cooling air blows upward from the bottom of the grate into the grate layer, permeates and diffuses, and cools the hot clinker. After cooling clinker, the cooling air becomes the hot air. The high-temperature hot air is used as combustion air into the kiln and precalciner (pre-decomposer kiln system). Some of the hot air can also be used for drying, the excess hot air is then dusted off and sent back into the atmosphere.

In the calcination process of cement clinker, preheating, calcining, and cooling are three inseparable process links. As the supporting equipment of cement rotary kiln, clinker cooler (also called cement cooler) is a kind of heat exchange device that transfers heat from high-temperature clinker to low-temperature gas. It plays an important role in the cement clinker production process and directly affects the cement product quality.

Cement coolers can be divided into the rotary cooler, grate cooler, vertical clinker cooler and more. While the rotary cooler and the grate cooler are now the most commonly used cement equipment in the cement plant.

Rotary Cooler: rotary cooler is the earliest used one in the cement plant. It is similar to the cement rotary kiln in appearance and equipped with refractory lining and material lifting device inside. The high-temperature clinker enters into the cylinder from one end, contacts with the cold air from the other end under the action of the lifting device, meanwhile carries out heat exchange. It is t is usually arranged under the cement rotary kiln, with a diameter of 2.0-5.0m, a length of 20-50m and a slope of 3-4%.

Grate Cooler: grate cooler is a kind of cement cooler that cools the clinker at a rapid rate. The temperature of clinker is reduced by cold air passing through the horizontally moving material layer from the bottom in a vertical direction. According to the movement of grate, grate coolers can be divided into rotary type, vibrating type, and reciprocatinggrate type.

four-roll crusher - roll crusher | agico roller crusher machine

Roll crusher, also called roller crusher machine, is a kind of traditional crushing mill, mainly used for the middle and fine processing of raw material applied in cement plant, chemical industry, building materials industry, etc. It is usually classified into three types: single-roll crusher, double-roll crusher and four-roll crusher. The double-roll crusher is the most commonly used one in the factory, but there are still many cases where it is not suitable. While the more efficient and reasonably designed four-roll crusher can bring a better crushing effect. AGICO provides a high-quality four-roll crusher with different capacities. They all have the characteristic of high yield, low noise, and long service life.

Four-roll crusher can be divided into two crushing stages from top to bottom. When working, motors will drive the belt pulleys on both sides of the crusher to rotate the two pairs of rollers. Rollers of the same stage run in the opposite direction and mesh with each other. When materials enter the crusher, the material with smaller particle size will directly pass through the middle clearance of the first pair of rollers into the second stage crushing. The clearance is equivalent to the sieve plate so that materials meeting the requirements of clearance (particle size) can fall automatically. Otherwise, they will be crushed by the rollers in the first crushing stage firstly, and then fall into the second crushing stage. The four rollers all move at a certain differential speed so that each pair of rollers can rub against each other, thus ensuring that materials with different moisture content do not stick or block when crushing. And because of the deceleration movement of the roller, materials are constantly turned over on the roller and crushed at the weakest point, so as to achieve the purpose of quickly crushing with the smallest force.
