The material through the feed tube fell into the center ofslaggrinding plant, and then the materials outwards the surrounding area of grinding plate at centrifugal force, to forms a certain thick layer of materials bed, at the same time material was crushed by number of vertical mill rollers.

The slag(slag product applications) materials continuous moving to the outer edge of the grinding plate, off the grinding plate materials rising with the hot air which enter from wind ring into the vertical roller mill, through the vertical roller mill shell into the middle of the separator, in this course materials and hot gas got a fully heat exchange, the water quickly evaporates.

Separator controls the finished product output size, greater than the specified size are separated and fall back to the plate, while meet the fineness demands are brought through the separator into the finished product warehouse.

Rod mill has a wide application range, especially when grinding in some special conditions:

1. To avoid the damages caused by over-crushing, gravity separation plant or magnetic separation plant for tungsten-tin ore and other rare metal ore always uses rod mill.

2. In some cases, rod mill can perform crushing instead of short head cone crusher. When processing soft or low-hardness ore, rod mill can grind 19-25mm (even 30mm) ore into 6-10mm. It is more simple and more cost-saving than the closed combination of short head cone crusher and separator, and moreover it simplifies the dust removal in ore-breaking workshop. However, short head cone crusher combining closely with separator is more economical when processing hard ore.

Thus, when making a project scheme, ball milland rod mill must be selected according to actual conditions.

The coal mill can be divided into low speed coal mill, medium speed coal mill and high speed coal mill. These three kinds of coal mills have their own good points, customers can choose each one suitable for production according to the actual demands.

The energy saving ball mill is a horizontal cylindrical rotating device, which has two cabins.

Coalmill is energy saving grateball milland the outside runs along the gear. The materials enter the first cabin of the mill spirally and evenly through the feeding apparatus and hollow shaft. In the first cabin, there is stepped liner or corrugated liner, and steel balls with different specifications. The centrifugal force generating from the rotation of the cylinder brings steel balls to a certain height, and then the balls fall, thumping and grinding the materials.

After coarse grinding in the first cabin, the materials enter the second cabin by single-wall partition. There is flat liner and steel balls in the second cabin, where the materials are grinded further. Finally, the powder is discharged through discharge grate and the grinding operation is finished.
