Raw Mill

Strong adaptability, large grinding ratio and continuous production

Raw mill is mainly used in grinding raw materials and end products in cement plant. It is also suitable for various ores and other materials from metallurgy, mine, chemical engineering and construction industries. Besides, it has two forms of milling. One is an open form, and the other is a closed recycle form equipped with a powder concentrator. It is widely applied in many industries and has convenient operations.

Materials:Cement clinker, limestone, calcite, dolomite, talc, etc.

Product Advantages

The use of new wear-resistant materials greatly improves the service life of wearing parts.

The PLC control system can be selected to improve the automation control level of the grinding mill.

The raw mills have closed structure, so there is less dust spill-over and it is beneficial and friendly to the surrounding environment.

ZENITH’s raw mills have an excellent balance between productivity and energy consumption. Users can get higher capacity under the premise of low energy consumption.

Working Principle of Raw Mill

As the mill rotates, steel balls work to grind the materials. The mill rotates approximately once every couple of seconds.
The grinding system uses either 'open circuit' or 'closed circuit'. In an open circuit system, the feed rate of materials is adjusted to achieve the desired fineness of the product. In a closed circuit system, coarse particles are separated from the finer ones and returned for further grinding.
When final products reach the fineness standard, they are discharged out of the mill.
