1000T / D cement production line process equipment

Products: cement production line is the production of cement, a series of ancillary equipment consisting of production line construction projects. Including crushing equipment,Homogenization equipment,Raw material preparation,Drying equipment,Preheat decomposition equipment,Clinker calcination equipment,Cooling equipment, grinding equipment, packaging equipment, transportation equipment, environmental protection and dust collection equipment, and so on. The Chaeng(Great Wall Machinery) provides cement production line process design, civil construction, complete sets of equipment, installation commissioning, technical services, general contracting.

Process parameters:

In the cement production line, each ton of Portland cement requires 3 tons of materials (including raw materials, fuels, clinker, mix, gypsum), according to statistics, dry cement production line grinding operations need to consume Of the total power of about 60% of the power plant, which accounted for more than 30% of raw materials grinding, coal mill accounts for about 3%, about 40% of cement grinding. Therefore, the rational choice of grinding equipment and process, optimize the process parameters, correct operation, control operating system, to ensure product quality, reduce energy consumption is of great significance.

production method:

Cement production to limestone and clay as the main raw material, by crushing, ingredients, through the vertical mill grinding raw materials, and then feed the cement rotary kiln calcinated mature material, and then add appropriate amount of clinker clinker, mixed with some mixed materials Or admixture, the roller press and cement mill grinding into cement, and then shipped by the packaging machine or bulk shipped factory. Cement production equipment with raw material preparation methods can be divided into dry cement production line and wet cement production line two. (1) dry cement production process: The raw materials are dried and grinded at the same time, or dried and then pulverized into raw material powder to be fed into the rotary kiln to calcinate the mature material. There are also raw material powder into the amount of water made of raw material balls, into the Li Boer kiln calcined raw materials in the method, called semi-dry method, is still a dry production of a. The main advantage of dry production is low heat consumption, with preheater dry kiln clinker heat consumption of 3140 ~ 3768 coke / kg, the disadvantage is that the raw material composition is not easy to uniform, workshop dust large, high power consumption. (2) wet cement production process: The method comprises the following steps: grinding raw materials into raw slurry by adding water, and feeding raw materials into calcined raw materials in a rotary kiln. There are also wet preparation of raw slurry dehydration, made of raw materials into the kiln kiln calcined mature material method, known as the semi-wet, is still one of the wet production. Wet production is simple, easy control of raw material composition, product quality, easy slurry transport, workshop dust less advantages, the disadvantage is high heat consumption, clinker heat consumption is usually 5234 ~ 6490 coke / kg.

The device contains:

The main equipment of cement production line includes: cement rotary kiln, cyclone preheater, cooling machine, crusher, vertical mill, roller press, cement mill, coal mill, dryer, dust collector, packing machine, bulk machine Machine, electrical control.
