Through decades of application and practice in crushing industry, as well as the improvement of serialization manufacture and technical level,the two-stage crusher designed by "Zhengtai Machinery " presents incomparable superiority.

Utilized in fuel workshop of thermal power plant, the machine can replaces jaw breaker, ring-hammer crusher and fine grinder etc, it features low investment, small occupied space, few operating personnel, economic and effective operation, its effects of energy conservation and consumption reduction are notable.

It is used in the fine crushing before the raw materials entering into the grinder in mines and cement plants, the basic principle of "more crushing, less grinding" is reflected,function of fine crushing is brought into fully playing to enhance the processing capacity of grinders, electricity consumption and steel ball consumption are reduced, volume of production of grinders is greatly increased.

Used in the brick making enterprises that are using coal gangue and shale to produce new type wall materials, the problems of raw materials with high moisture troubling normal production of brickyard is solved , the particle grading is reasonably, particualarly suitable for production of perforated brick and thin brick.

The crusher is equivalent to two sets of hammer crusher and combined into a whole one reasonaly, cascaded using of two sets of rotors without screen, has the following characteristics:

I. Dual Rotor Crushing in Up and Down Two-stage

Two sets of cascade rotors make the materials crushed by up stage rotor hammer be fine crushed by the rotary down rotor hammer, materials in the inner space collide with each other reversely and smash one another, the effect of hammer crushers materials and materials crush materials is achieved, and they can be unloaded directly.

II.No Screen, No Blocking for Materials with High Moisture Content

The traditional crushers with grate sieve plate can not meet the raw materials wih the moisture content higher than 8%, serious blocking will occur if the moisture content of raw materials is higher than 10%, and the hammer can not rotate and materials can not be discharged, even the motor will be burned out and effect the production.


The design of the crusher is without screen, it has no strict requirements on moisture content of raw materials, the problem of blocking on the sieve plate is absent, and troubles that fine powers can not be discharged in time and repeated grinding do not exist either, so the grinding efficiency is high, and invalid abrasion of hammer does not exist.
