Ball mill for cement grinding process

Two chamber mills are used for grinding cement, slag and similar materials. They are typically arranged in a circuit with high efficiency VTP separators. They grind materials up to 6500 cm 2 /g according to Blaine. The mill itself is equipped with a lifting armoring in the fi rst chamber with larger balls with a high comminuting effect. The second chamber is equipped with classifying armoring using smaller balls for fi nish grinding.

Ball mills with different chamber

The partition diaphragm is equipped with a controllable material flow so that both chambers maintain an optimum fi lling ratio. Material from the second chamber is supplied to a separation circuit via an outlet wall. In case warmer materials are ground, water is sprayed into the second chamber or both chambers. In case the grinding circuit includes a roller press, single chamber mills with classifying armoring without a partition diaphragm are used.

One- and two-chamber raw mills with a pre-drying chamber

One- and two-chamber mills with a pre-drying chamber are used for grinding material for kiln lines. They are arranged in a circuit with a high effi ciency VTP separator for simultaneous drying of raw materials with kiln gas or heat from the grate cooler. These circulating grinding plants are suitable for grinding and drying of materials with a moisture content of up to 8%. The outlet product, raw meal is ground to fi neness 12÷14% R90 with a moisture content of 0.5%.

All components of the raw material are supplied to the pre-drying chamber where they are dried before they pass through a parting plane to the mill. The reject coarse material from the separator is taken to the mill inlet. The seating and drives of the mill are similar to cement mills.

Pneumatic mills are equipped with one grinding chamber with a pre-arranged drying chamber. The material supplied to the mill is ground and then taken by air to a high ef fi ciency separator LTR. The fi nal product is collected in cyclones or a filter. Pneumatic mills are used for grinding and drying of very moist materials. Drying is possible with a large volume and high temperature of the drying gas fl owing through the drying chamber, mill and separator. Pneumatic grinding plants are known for their simple design and reliability.

Pneumatic grinding plants are designed also for grinding of coal and petroleum coke in a circuit with a high ef fi ciency separator LTR-U with a pressure drop of up to 3.5 bar.

Cement ball mill manufacturer

Cement ball mills are one of our primary cement plant. We design cement ball mill with high capcity and long working time. Our ball mill includes raw mill, rod mill, cement ball mill, ceramica ball mill, bowl mill and ball roller mill. Ball mill is usually an efficient tool for milling numerous supplies in to high-quality powder. This Ball Grinding machine can be used to grind many kinds of quarry and also other materials, and to find the mine, widely used within constructing subject matter, chemical manufacturing, for example. There are two techniques for milling: the dry process and the wet process. It is usually divided into tabular type and flowing type in response to different forms of discharging material.
