Combination Crusher

Combination crusher is widely used in the fields of various minerals, cement, refractory material, bauxite clinker, silicon carbide, glass raw material, etc. Combination crusher is also very popular in the crushing of artificial building sand, stones and various metallurgy ores. Compared with other types of crushers, this crusher can produce products efficiently. Compound crusher has a bigger reduction ratio, and the biggest one can reach the degree of discharging granularity. The adoption of elastic adjusting mechanism enables the uncrushing materials to be discharged automatically, which can avoid the damage to the equipment. The compound crusher is able to crush materials (cement clinker) in high temperature.

Superiorities  

Compound crusher has big ratio of reduction which makes it the best choice for manufacturers. The discharging granularity can be adjusted at will;  there is no diagrid design as well. It will not be blocked by the high sediment-content materials. The uncrushing materials can be discharged automatically without damaging the machine itself. This kind of compound crusher has features of high productivity efficiency, unique structure, steady operation, low noise, easy maintenance, easy replacement of the wearing parts, etc. 

Structure 

Compound crusher is composed of the transmission, principle axis, barrel, upper cover and base etc. The main axis is driven by the motor through the trapezoid triangle. A hammer is installed in the principle axis and the materials can fall into the machine from the upper feeding inlet, then drop by gravity. Materials will be crushed by a series of continuous impact by high-speed rotating hammer and discharged from the lower discharging hole. 

Working principle 

Materials fall vertically into high-speed rotating impeller from the machine . After mutual impact, they would impact, rub and smash with each other under eddy current formed by the materials between impeller and chassis, and then discharged directly from the lower part. A closed multi-circulation has been formed and the screening equipment controls it to get the finished products with demand granularity. 

Working characteristics 

1.Simple and rational structure, low operating cost. 

2.High crushing efficiency, energy saving. 

3. Function of fine crushing and coarse grinding. 

4.Not easily influenced by the water content in materials. 

5.Working noise is under 75db, less dust pollution. 

6.Suitable for medium and ultrahard crushing. 

7.Finished products are cubic with large bulk density, minimal iron pollution. 

8.Small abrasion of the impeller lining, easy to be maintain.
