Product FEATURE

Cement clinker grinding plant (Clinker Grinding Station) acts as an individual production line in the last period of the cement production process. In the finished product period, the cement clinker is ground by adding moderate mixing materials and then transforms to the finished cement (cement Portland).
1. High Efficiency
Cement grinding plant has high automation level, the operating process will adopt DCS central control system for adjustment, control and alarm in master control room, then the whole plant have less operator and also increase the working efficiency. The batching system have been adopt automatic quantitative feeding and measuring device, which have increase the material batching accuracy and also stablilizing the production’s quality.
2. Saving Energy
Adopting tube mill or vertical roller mill to producing qualify cement according to the raw material’s condition of clients. Producing system have adopt closed circuit to reduce the energy consumption of cement grinding. The single line scale can be from 15tpd to 1500tpd, which have been covered the cement factory’s different manufacture demand.
3. Environmental protection
Adoption of High efficiency air classifier and pulse type bag filter have created the circumstance for energy saving and energy consumption reduction.
4. High degree of automation
There is no manual operation in the process of mill running, which realizes the automatic control with long-term, stable, effective, makes milling process more stable, realizes fine work of production.

PRODUCTION PROCESS

There are three procedures of the cement grinding plant: raw material preparation, clinker burning and cement making. The production technology of the silicate cement is regarded as the representative one in the cement industry. It uses the limestone and clay as the main raw materials which are crushed, dosed and ground to be the primary raw materials. Then they are burnt to be clinker inside the cement kiln, and by adding certain gypsum (sometimes the mixed material or admixture) and do fine grinding, we get the finished products.

The cement grinding technology is adopted by investors as circuit cement grinding processing, which have various advantages like high manufacture ability, high automation level, good production quality, less energy consumption, more industry waste using quantity, so have been as the main technology of world-wide cement manufacture.

The cement manufacture process of grinding station, have be adopt open circuit manufacture process, and mostly application is closed circuit manufacture process which meaning ball mill grinding system match with air classifier.

As for the cement producing scale is bigger and bigger, the roller mill is widely used in the grinding system, which will reduce the feeding size of ball mill, greatly increase the producing capacity and decrease grinding energy consumption.
