Raw mill is generally called cement raw mill, raw mill in cement plant, it refers to a common type of cement equipment in the cement plant. In the cement manufacturing process, raw mill in cement plant grind cement raw materials into the raw mix, and the raw mix is sent to the cement kiln to make cement clinker, next, clinker and other admixtures will be ground into finished cement by cement mill.

As for the type of raw mill, there are two types including cement ball mill and vertical cement mill. In the traditional cement raw mill system, the cement ball mill system is more typical. After technology modification, the vertical cement mill has obvious advantages compared with the cement ball mill, and it is suitable for the large cement production line.

AGICO CEMENT is a raw mill manufacturer from china who has the ability to manufacture cement ball mill and vertical cement mill. As a leading and trusted manufacturer, we had exported many projects of cement raw mill and cement equipment to the countries or regions around the world. Why AGICO CEMENT is popular?

Vertica raw mill, also known as vertical roller mill, in the 1920s, the first vertical raw mill in cement plant is designed in German. It is widely used in cement, electric power, metallurgy, chemical industry, and other industries.

Low investment: the vertical raw mill set crushing, drying, grinding, grading transportation in one, simple system, compact layout, less space, it also can be arranged in the open air, save a lot of investment costs.Low operation cost: small energy consumption and less damage reduce the running cost.Environment protection and clean: small vibration, low noise, and good sealing, the system works under negative pressure, no dust overflow.Stable quality of raw mix: because the material stays in the raw mill for a short time, it is easy to detect and control the product size and chemical composition, reduce repeated grinding, and stabilize the product quality.

The main motor drives a millstone by rotational speed reducer, at the same time the wind enters into the raw mill from the air inlet, material through the screw feeder fell in the middle of the raw mill, under the action of centrifugal force, the raw materials move uniformly from central to the edge of the millstone, the materials will be ground by the roller when it passes through the grinding roller way, large materials are directly crushed. Crushed material continues to move to mill edge, until being taken away by the wind ring in strong turbulence, and larger particles material again fell to the mill to continue to crush, the flow of materials through the upper part of the separator, in the effect of separator blade, coarse particle back to the grinding mill, qualified fine powder with airflow is out of the raw mill, and collected by the powder collection.

The cement ball mill usually can be applied to raw meal grinding or cement grinding. Besides, the cement ball mill also can be used for metallurgical, chemical, electric power, other mining powder grinding, and other grindable materials.

Safe and reliable system: the maintenance of the reduction gear and gear is more convenient, firm and wear-resistant, and also reduces the downtime, maintenance time and the labor intensity of the operators.

Good wear resistance and long service life: Cement ball mill adopts the high-quality wear-resisting material, and the lining can be removed, therefore the service life of the equipment or vulnerable part is all longer.

The main working part of cement ball mill occurred in the low-speed rotary cylinder, when the cylinder is drove to rotary, grinding medium is attached on the liner to rotary together due to the effect of inertial centrifugal force, and taken to a certain height, freely fall because of gravity, grinding medium break the materials in the cylinder body, at the same time the grinding body in the rotary raw mill have circular motion, also can produce sliding and rolling, which result in grinding among the grinding medium, liner, and materials. When the material is crushed and ground by impact, the material flows slowly from the feeding end to the discharging end to finish the grinding operation.

The raw mill is a kind of necessary cement equipment in the cement plant. In the real working condition, but the large configuration will produce a bad effect on the cement plant, so it is very important to set a reasonable configuration of the raw mill. There are five reasons why we control the configuration of the raw mill in cement plant:

Composition fluctuation of the raw meal: The frequently start-stop of a raw mill will bring different degrees of influence on the quality, whether it is the cement ball mill, the vertical cement mill or the cement roller press system.

Raw mill is made up of feeder part ,discharging part ,rotating part ,transmission part(reducer,samll transmission gear ,motor,electric control) etc. It's a key equipment for grinding materials, widely used in powder-making production line such as cement, silicate sand, new-type building material, ore dressing of ferrous metal and non-ferrous metal, etc. Do your know how does the raw mill work in the cement plant? This paper mainly introduces the raw mill in cement plant.

In order to achieve the desired setting qualities in the finished product, a quantity (2-8%, but typically 5%) of calcium sulfate (usually gypsum or anhydrite) is added to the clinker and the mixture is finely ground to form the finished cement powder. This is achieved in a cement raw mill. The grinding process is controlled to obtain a powder with a broad particle size range, in which typically 15% by mass consists of particles below 5 m diameter, and 5% of particles above 45 m. The measure of fineness usually used is the "specific surface area", which is the total particle surface area of a unit mass of cement. The rate of initial reaction (up to 24 hours) of the cement on addition of water is directly proportional to the specific surface area.

The cement is conveyed by belt or powder pump to a silo for storage. Cement plants normally have sufficient silo space for 120 weeks production, depending upon local demand cycles. The cement is delivered to end-users either in bags or as bulk powder blown from a pressure vehicle into the customer's silo. In industrial countries, 80% or more of cement is delivered in bulk.

Our raw mill has been widely used in the cement making plant. In a large number of customer feedback, we received a lot of enthusiasm and positive reaction. They speak very highly of our machines. According to a lot of customers' response, this plant generally have the following four advantages.

Bauxite crushing: bauxite is the addictive. For making cement raw materials, bauxite is crushed by cement equipment into powder. Then bauxite particles and limestone particles together are ground into raw powder by raw mill.

Gypsum crushing: gypsum powder made by gypsum crusher and gypsum mill is put into cement clinker together with coal powder, and then the cement raw material enters into the cement mill for fine grinding.

In the cement production line, most of the material need to be broken, such aslimestone,clay,iron ore and coal, etc. Limestone is the largest amount of raw material in cement production, after mining the size of limestone is large, with high hardness, so the limestone crushing plays a more important role in cement plant.

In the cement production line, producing each 1 ton of Portland Cement need grinding at least 3 tons of materials (including raw materials, fuel, clinker, mixed materials,gypsum).Grinding operation consumes power about 60% of total power in cement plants, raw material grinding takes more than 30%, while coal mill used in cement plant consumes 3%, cement grinding about 40%. So choosing the right grinding mills in cement plant is very important.

Cement grinding is used for grinding cement clinker (and gelling agent, performance tuning materials, etc) to the appropriate size (in fineness, specific surface area, said), optimizing cement grain grading, increasing the hydration area, accelerating the hydration rate to meet the requirements of cement paste setting, hardening.

The characteristics of the slipper bearing mainly as the follows: 1) with a sliding shoe bearing mill wheel can have two, three or four, so its structure is not only fully applicable to small and medium sized mills, but without specification limit, you can also use the large mill.

2) using slipper bearing structure, can cancel large grinding machine is easy to damage the grinding head (including the hollow shaft) and main bearing, safe operation, and can shorten the length of the mill, especially the feed end of the mill obviously shortened a lot, reduce cover an area of an area.

3) for drying and grinding mill, due to the cancellation of the hollow shaft, feed off area not subject to the mouth of the hollow shaft, therefore, can be more rational design of the inlet, is conducive to grinding materials and hot air by and reduce the ventilation resistance.

4) due to the mill supporting distance shortened, so the grinding cylinder bending moment and stress reduced accordingly, as a result, the thickness of the steel plate mill cylinder body can be thinned. Especially drying and grinding mill, drying storehouse of cylinder can use thinner steel, reduce the weight of the mill.

5) belting leather linear velocity is much taller than hollow shaft neck, favorable for the formation of lubricating film. Slipper bearing because of belting leather and shoe of machining accuracy and roughness requirement is strict, so the high cost of the main bearing grinding machine. Slipper bearing structure and maintenance is more complex, once a link in the system failure, require timely detection and repair, it will affect the normal operation of the mill, therefore request furnish corresponding monitoring and control instrumentation.
