What are the commonly used equipment in cement plants?
Commonly used equipment in cement plants include
1. In the firing workshop: coal pre-homogenization equipment, coal mill, rotor scale, preheater, rotary kiln, cooler, etc.
2. Cement workshop: cement blending, roller press, cement mill, packaging machine, etc.
3. In the raw material workshop: limestone crusher (hammer crusher, jaw crusher, etc.), stacker and reclaimer for limestone pre-homogenization, and raw material mill.
4. Various metering belts, belt conveyors, fans, and circulating water systems.
The cement production process is usually summarized as two grinding and one burning, which is divided into three stages: calcareous raw materials, clayey raw materials and a small amount of calibrated raw materials are crushed, mixed in a certain proportion, ground and prepared into raw meal with appropriate composition and uniform quality. , is called raw meal preparation; the process in which raw meal is calcined in a cement kiln until it is partially melted to obtain Portland cement clinker with calcium silicate as the main component is called clinker calcination; an appropriate amount of gypsum is added to the clinker, mixed The materials or additives are ground together into cement and packaged or shipped in bulk, which is called cement grinding and shipment.
Starting from the raw materials, the limestone is transported from the mine to the factory via a belt conveyor. After being crushed by the limestone crusher, the belt conveyor is transported to the limestone warehouse. There is a bag dust collector at the dust point in the middle; the batching station contains limestone, sandstone, and iron powder. , Fly ash (the process design is different, the raw materials may be slightly different) is sent to the raw material mill (now usually a vertical roller mill) through a belt scale and belt conveyor, and after grinding, it is transported to the air chute and bucket elevator. Raw material warehouse. The raw material is sent to the preheater via a bucket elevator, where it is preheated and decomposed into the kiln for calcination. The clinker is cooled by the grate cooler, crushed by the clinker crusher, and sent to the clinker warehouse via the chain plate machine. The clinker, mixed materials, and gypsum are transported to the cement mill (ball mill) via a conveyor for grinding, and the finished products are put into the cement warehouse and shipped out of the factory through a packaging machine or in bulk. There are also humidification towers (cooling and dust removal, improving dust specific resistance), electric dust collection (dust removal) and other equipment.
What equipment is needed to produce cement?
1. Crushing equipment: commonly used jaw crushers, hammer crushers, impact crushers, etc.; 2. Conveying equipment: belt conveyors can be used; 3. Grinding equipment: air-swept coal mill, slag mill, cement mill Mill, raw material mill, etc.; 4. Calcining equipment: cyclone preheater and cement rotary kiln are generally used; 5. Cooling equipment: single-cylinder cooler; 6. Dust removal equipment: air box pulse bag dust collector can be used; 7. In addition, equipment such as powder selection equipment and cement bulk machines need to be added.
What are the main equipment of the cement plant?
Host equipment: including kiln, raw meal vertical mill, cement mill, high temperature fan, tail exhaust fan, kiln head fan, grate cooler, stone crusher, each water pump motor, etc. all need cooling water circulation cooling, as well as major motors. There are too many needs. Cement plants have circulating water systems. Due to the long running time of the main equipment of the cement production line, the supporting cylinder sections, large gears, hollow shafts, supporting wheels, etc. have been worn to varying degrees, causing frequent equipment failures, affecting production, and in severe cases, causing personal and equipment accidents. occur. Therefore, timely maintenance of production equipment and replacement of spare parts can not only reduce equipment failures, but also improve equipment operation rate, effectively extend the service life of equipment, and ensure more efficient operation of equipment in the future. As a well-known large-scale kiln grinding service provider in China, Xinxiang Great Wall provides a full range of kiln grinding equipment spare parts services. It can produce various types of machinery and equipment spare parts for building materials, cement, metallurgy and other industrial industries, including grinding roller assemblies and rollers in vertical grinding equipment. sets, grinding disc linings, etc. The rotary kiln cylinder, large ring gear, wheel belt, supporting wheel, etc.; the hollow shaft of the ball mill and other host accessories are processed and customized to provide customers with the main spare parts needed for the entire kiln grinding equipment to meet the needs of different industries.
