Fine Impact Crusher Introduction:

Regarding the working principles of the various crushers, according to the user specific service condition information feedback, and combining its features, Shanghai Ming gong has designed this new generation of high-efficient fine crusher. It is specially used in the area of artificial sand making, and it is the substitutes of the rod mill, and the vertical shaft sand making. Moreover, it is widely used in the areas of chemical , building material, metallurgy, mining, coal, sand crushing and refractory material, especially for crushing the materials of the medium hardness, such as limestone, cement clinker, iron ore, shale, dolomite, granite, gypsum, and mix materials, etc.

Working principles:

During operation, fine impact crusher is driven by the motor which makes the rotor revolve in high speed. When the materials are sent into the first cavity, it will be impacted by the hammer; and then be smashed into the second fine cavity for crushing, finally it is discharged out.

Features and Benefits

1. The reasonable multi-cavity crushing room combination, and the new convenient bitonality structure, can guarantee 85% material granularity size is below 5mm, the product granularity are fine and even;

2. This equipment investment is lower 35%-50% than the traditional process with same scale, but productivity is higher 35%-50%. And the cost of the long-term maintenance is lower 35%-50%.

3. Convenient maintenance installment makes the hammer and screen plate exchanged easily.

4. The worn parts mainly adopt the new high quality multi-element chromium alloy anti-friction material, guarantee the hammer and the plate have superior abrasion and impact resistance

5. Big capability, the hammer has long service life , low power of the necessary device, can change the three-level crushing into two-level crushing, simple craftwork and structure, easy maintenance, steady operation, low dust and electricity consumption.
