Coarse mill

The coarse mill is also called coarse grinding, European version of hammer crusher. The discharge particle size is adjustable such as 0-3mm, 0-5mm, 0-8mm.

Feeding size:

30-50mm

Output size:

0-3mm

Capacity:

8-100tph

Suitable material:

Suitable for crushing quartz, feldspar, limestone, calcite, marble, dolomite, barite, talc, calcium carbonate, gypsum, swelling, etc. Various soft and hard ores with a crushing compressive strength not higher than 320MPa (MPa)

Description

 The coarse mill is suitable for coarse powder grinding , sand making, power plant desulfurization, glass raw material grinding and many other industries.

Working principle

The main machine drives the main shaft through the motor and the V-belt, so that the rotor rotates, and the centrifugal force generated by the rotation of the hammer head is extended to the periphery. After the bulk material enters the crushing chamber from the feeding inlet, it is crushed by the high-speed moving hammer. The crushed qualified materials are discharged by the grid section with gaps in the lower part, and the unqualified ones are left in the crushing chamber, and are repeatedly used by the hammer and the striking iron block until they can be discharged. In order to avoid clogging, the moisture content of the pulverized material generally does not exceed 20%.

Product Advantage

1. The output size can be controlled according to actual demand.

2. The shape of the final particles are almost in cubic shape.

3.Simple structures, compact and convenient.
