Hammer Crusher

Project Description:

Hammer crusher

Working Principle of Hammer Crusher

The motor drives the rotor rotates of the Hammer Crusher 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, they are crushed by the rotating hammers of the Hammer Crusher with high rotation speed, 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 crushed area by the hammers of the Hammer Crusher for being re-crushed until they reached the required size.

Product Advantages of Hammer Crusher (Hammer Mill) 

Simple structure,
High reduction ration,
High efficiency,
Low Cost
Features of Hammer Crusher:

1. The enhancement rotor is designed with finite element analysis technology.
2. High crushing ratio. The crushing ratio ranges from 10 to 25 or even higher to 50.
3. The AMC alloy hammerhead enjoys a service life increased by 50~150%.
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 3-4 times.

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 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 hammers 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. Rotate the handling along the sides of the machine to make an angle for the eccentric, the grates frame can be raised up or lowered down, which can adjust the gap between the hammer and the grates, and then the product installation can be completed.
hammering machine

The hammering machine crushes the material with the impact force of the hammerhead. The most common hammer mill is also namedhammer mill crusher. When the materials enters the hammer mill, they will encounter the hammerhead which is doing high speed rotation and then be crushed. The crushed materials will be discharged 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 for crushing the ore in the dressing plant.
