Cement equipment production line
Cement production line is a cement equipment production line composed of a series of equipment to produce cement. It is mainly composed of crushing and prehomogenization, raw meal preparation homogenization, preheating and decomposition, cement clinker burning, cement grinding and packaging.
Main process equipment: cement rotary kiln, grate cooler, dryer, cement ball mill, cement powder concentrator, etc.
1. Cement rotary kiln:
Cement rotary kiln belongs to building material equipment, which is horizontal rotary calcination equipment. With horizontal rotary calcination, the materials are evenly heated in the kiln, the quality of calcined clinker products is stable, and the clinker strength is high.
2. Grate cooler:
Grate cooler is an important equipment in the clinker burning system of the cement plant. Its main function is to cool and transport the cement clinker. Meanwhile, it provides heating air for the rotary kiln and decomposition furnace, which is the main equipment for heat recovery of the burning system.
Grate cooler is a kind of quench cooler. After the clinker enters the cooler from the kiln, it is laid into a certain thickness of material layer on the grate plate. The cold air bubbling through the moving material layer on the grate bed in a mutually perpendicular direction makes the clinker quenched. The clinker can be quenched from 1300-1400 ℃ to below 100 ℃ in a few minutes.
The traditional grate cooler can be divided into three types: rotary type, vibrating type and pushing type. However, since the first two types have been eliminated, the pushing grate cooler has become the main type of cement clinker cooler used in the decomposition kiln outside the kiln. The grate bed is the main part of the cooler, and the push grate plate is composed of fixed grate plate and movable grate plate arranged in rows.
The block type swing support cooling machine is another innovative technology, in which the hydraulic drive system clinker roller crusher, the block type swing support system without wear and the side end direct air supply technology are introduced. The newly launched fourth generation grate cooler has a high-efficiency clinker conveying system. There are no conveying parts on the bed, so there are few parts, and the maintenance cost and wear of parts are significantly reduced.
The dryer is mainly used for drying materials of certain humidity or particle size in mineral processing, building materials, metallurgy, chemical industry and other departments. Rotary dryer has strong adaptability to materials, can dry various materials, and the equipment is simple and reliable, so it is widely used.
4. Cement ball mill:
The ball mill is the key equipment to crush the material after it is broken. Ball mill is widely used in cement, silicate products, new building materials, refractory materials, fertilizer, black and non-ferrous metal beneficiation, glass ceramics and other production industries, to dry or wet grinding of various ores and other grindable materials.
5. Cement powder concentrator:
Powder concentrator is a kind of powder separation equipment, which is widely used in the dry powder separation process. There are many types of powder concentrators, different structure types are suitable for different materials, and different models are also made according to the requirements of customers for the fineness of materials.
