Cement Grinding Process Explanations

Clinker Grinding Introduction

Clinker grinding refers the method that material is grinded into fine powder under external force, impact, extrusion, and grinding effect.

On the one hand, clinker grinding could be the last step during the cement production process. So the cement grinding method control is directly related to the cement item good quality, yield, and expense. On the other hand, cement grinding could be the step consuming probably the most power. So picking top quality clinker grinding mill is extremely essential to increase company’s economic positive aspects.

Clinker grinding process

1. Open sort clinker grinding process

Materials delivered by way of clinker mill are the merchandise. The easy approach calls for fewer equipments, less investment, but could effortlessly cause heavily milled powder

2. Closed type clinker grinding process

The grinded supplies are chosen by classifier system. The coarse one returns to grinding mill once more, in order to cut down heavily milled powder. The closed variety clinker grinding procedure can boost yield, lower power consumption, and product fineness is straightforward to control. But the system requires significant investment, and complex operation and upkeep.

Factors which influence the cement output

1. Hardness of raw materials

Gypsum can improve grinding possibility of whole system, improving the output each and every machine. limestone is uncomplicated to become grinded, which can significantly increase the production of machine. Slag itself is hard to be grinded, but for those who add a specific volume of slag, you may enhance the output. Fly ash itself is just not straightforward to become grinded. However, given that itself is fine powder, it can tremendously make the raw mixture uncomplicated to become grinded.

2. Granularity of raw materials

Raw mixture of fine specific size does not require huge steel ball. The smaller the specific size is, the easier the raw mixture is for ball mill .

3. Quality of cement mill

Substantial scale cement ball mill can improve grinding efficiency, save power, and enhance economic benefit.

4. Production manage system

Input raw supplies uniformity Input raw supplies temperature Grinding material moisture Impact of raw mixture Grinding AIDS agent influence

5. Type of cement grinding process

You can find two types of cement production method: open cement grinding method and closed form of cement grinding production. Usually, much more cement plants adopt closed grinding process due to the fact it has greater output than open grinding procedure.

Cement ball mill

Cement ball mill, also names cement mill, cement clinker mill, is the important equipment for grinding cement clinker, gypsum, limestone, clay, coal immediately after crushing procedure. This really is basically a big rotating drum containing grinding media – generally steel balls. As the drum rotates, the motion from the balls crushes the clinker. The drum rotates approximately when every couple of seconds.

Grinding systems are either ‘open circuit’ or ‘closed circuit.’ In an open circuit program, the feed rate of incoming clinker is adjusted to accomplish the desired fineness of the item. In a closed circuit program, coarse particles are separated from the finer product and returned for further grinding. Systems have been installed on Cement clinker, blast furnace slag, calcined alumina, calcium carbonate. Dry ball mills are efficient grinding systems in the common range of 500 microns down to 5 microns.

As the professional manufacturer of complete sets of mining machinery, such as China spiral classifier,Shaking concentrator,cement mill,Flotation separator, Henan Hongxing is always doing the best in products and service.
