Brief description of Hammer Crusher
The hammer crusher, also named hammer mill, crushes by the collisions between high-speed hammer and materials. It has features of simple structure, high reduction ration, high efficiency, etc. As the main equipment in stone crusher plant, hammer crusher is ideally suitable for crushing all kinds of ores and any big-sized materials. For this kind of stone crusher, the highest anti-pressure strength of crushed material is 320 MPA.
We produce various types of rock crusher(s) like single hammer crusher(s) and PCZ heavy hammer crusher(s) which all serve as secondary cone crusher. They are widely used for crushing various materials like stone, granite, trap rock, coke, coal, manganese ore, iron ore, emery, fused aluminum, oxide, fused calcium carbide, lime stone, quartzite, alloys, etc.
These crushers are recommended by leading consultants in rock crushing plant and are used by hundreds of customers all over the world.
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.
Working Principle of Hammer Crusher:
In the hammer crusher machine, the motor drives the rotor to rotate at a high speed through the belt, and on the rotor there are a series of hammers. When the materials get into the working area of hammers, the rotating hammers with high rotation speed will crush them, and the products which are crushed to meet the required size can be discharged by the outlet and become the final products, then the large size products are brought back to the crushing area by the hammers for being re-crushed until they reach 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 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 named hammer 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.
