Cement mill is one of the most widely applied grinding equipment used by the cement enterprise, the advantages of the cement mill mainly include simple structure, convenient operation, strong adaptability to raw materials; which also is of big crushing ratio, easy to adjust the grinding fineness of product and with better mixing effect; it also can grind materials both for dry operation and wet operation. Its disadvantages include: large grinding body and lining board consumption; large noise figure; bulky; especially low work efficiency and high power consumption.
Over the years, cement mill manufacturers both at home and abroad have conducted a number of exploration and attempt for the increasing production, exploring the potential and energy saving of cement mill, a series of effective measures have been put forward and we also obtained a lot of mature experience, such as reducing the moisture and temperature of the raw materials entering the cement mill, strengthening the ventilation inner the mill, improving the grindability of the materials, modified the open circuit mill to closed-circuit mill, grinding materials respectively, using rubber lining, setting a curved screen and so on, which all have achieved good results.
The cement production line is a professional cement producing process, which is composed of crusher, raw material mill, cement rotary kiln, cooling machine, cement mill and so on. The Portland type cement production line is the representative in cement production. This cement production line treats the limestone and clay as the main raw material, gets the raw meal through crushing, compounding and levigating. And then, the raw meal is made into clinker through the cement rotary kiln. At last, put some gypsum into the clinker, ground by the cement mill.How to distinguish the cement production line? It is mainly depends on
the preparation of raw meal. Generally speaking, the cement production line can be divided into dry-process cement production line and wet-process cement production line. impact breaker:http://www.china-hxjq.com/p4.html
A. The dry-process cement production line
The dry-process cement production line is a way to do the drying and grinding for the cement stone at the same time, or grinding after drying. At last, put the raw meal, which has been through dry and grinding, into cement rotary kiln to get the clinker.
B. The wet-process cement production line
The wet-process cement production line is a way to put some water into the cement stone, through grinding to make the cement stone into slurry first; and then put the slurry into the wet kiln to get the clinker.
Now the engineer of Hongxing Mining Machinery Co., Ltd. will introduce three methods about improving the output of cement mill.
1. Add a fine crusher in front of the cement mill.
The fine crusher decreases the particle size of materials that will be put into the cement mill, which reduces the load of grinding system.
2. Improve the grinding system of cement mill, improve the grinding efficiency.
Improving the grinding efficiency, the most direct benefit is getting the finished powder maximum in time, reducing the rate of cement products back to the flour yield, decreasing the load of cement mill.
3. Add a high efficiency separator. The small particle size of raw material is, the high grinding efficiency is. If the grinding efficiency is low, not only the output of cement mill, but also the quality of cement will be influenced.
