Hammer crusher

الوصف

The hammer crusher also named hammer mill , it crushes by the collisions between high-speed hammer and materials, has features of simple structure, high reduction ration, high efficiency etc. As one of the main equipment in stone crusher plant, hammer crusher is ideally suitable for crushing all kinds of ores and any big size materials. For this kind of stone crusher, the highest anti-pressure strength of crushed material is **0 MPA.

Features of Hammer Crusher:

1. The enhancement rotor is designed with finite element analysis technology.
2. High crushing ratio. The crushing ratio ranges from *0 to *5 or even higher to *0.
3. The AMC alloy hammerhead enjoys a service life increased by *0~**0%.
4. The theory of stone hitting effectively reduces the wear load of hammerhead and grid plate.
5. The military high strength artillery steel spindle is designed with vacuum duplex which increases the strength by **4 times.

Working Principle of Hammer Crusher:

In the hammer crusher machine, the motor drives the rotor rotate at a high speed through the belt, and on the rotor there are series hammers. When the materials get into the working area of hammers, the rotating hammers with high rotation speed are crushing them, the products which are crushed to meet the required size can be discharged by the outlet and become the final products, the large size products are brought back to the crushing area by the hammers for being re-crushed until they reached the required size.

Structure of Hammer Crusher:

The hammer crusher mainly consists of the box, disk, axis, hammer, grates, adjusting frame and coupling. The housing of the hammer crusher is a box made of steel plate, which can be divided into two parts of the upper and the lower along the center of the axis. The two parts are connected by the bolts. To avoid abrasion and transformation of the inner wall of the box under the impact of the materials, there are protecting scale boards in the housing of the hammer crusher. The types of disk are triangle and circle, with the former easy to be abraded than the latter. There are 6 mandrels on the disk, through which the hammer are installed staggered on the disk .The axis of rotator is supported by the axis on the ends. The grates are arranged by the grate frame, which is fixed on the box by bolts. The quill shaft is arranged with two eccentric shafts under the box. Rotating the handling along the sides of the machine to make an angle for the eccentric, the grates frame can be risen up or lowered down, which can adjust the gap between the hammer and the grates, and then the product can be completed.

The hammering machine crushes the material with the impact force of the hammerhead. The most common hammer mill also named hammer mill crusher. When the material enters into the hammer mill, it will encounter with the hammerhead which is doing high speed rotation and then be crushed. The crushed material will discharge from the lower end of the machine.

This machine is used for the stone crushing, such as the building stones. So it also named rock crusher , it can be used to crush the ore in the dressing plant.
