Heavy hammer crusher is suitable for treating medium and soft minerals, such as limestone, coal gangue, dolomite and shale. It can also handle materials with high hardness, but the hammer wears quickly, the better the frequency. The heavy hammer crusher adopts the principle of impact crushing, and the material is repeatedly hit and crushed between the plate hammer and the impact plate.

Basic structure principle of heavy hammer crusher

Heavy hammer crusher consists of shell, motor rotor, striking plate, high chromium alloy hammer head, support frame, jaw plate and so on.

1. The shell consists of upper body, rear top cover, left side wall and right side wall, which are connected into a whole by anchor bolts. The upper end is provided with a feed inlet, and the inside is inlaid with a high manganese steel jaw plate, which can be disassembled and replaced after damage. The ash leakage between the shell and the shaft is very serious. In order to better avoid ash leakage, a water pump seal is set. The bottom of the shell is immediately placed on the concrete foundation and fixed with anchor screws. In order to better facilitate the maintenance, adjustment and replacement of the bars, the front, back, left and right sides of the lower machine body are provided with access ports. In order to facilitate the maintenance and replacement of the high chromium alloy hammer, inspection ports are symmetrically opened on both sides of the wall.

2. The motor rotor is composed of spindle bearing, disc and pin shaft. There are six evenly distributed pin holes on the disc, and 6-8 hammers are hung according to the pin shaft. So as to better avoid the radial vibration of the disc and the hammer. Both sides of the pin shaft are fixed with lock nuts. The motor rotor is supported by two roller bearings. In addition, in order to better make the motor rotor store certain mechanical energy in fitness exercise, prevent the high chromium alloy hammer from losing too much speed when crushing massive raw materials, and reduce the load of the motor, one end of the spindle bearing is also equipped with a water pump flywheel.

3. The spindle bearing is the key component to support the motor rotor, and the impact force is borne by it. Therefore, it is stipulated that its material has high ductility and compressive strength. The cross section is generally annular, and the Ping Jian is connected with other parts.

There are two striking plates, which are dotted lines. One is adjustable and the other is fixed. One of the adjustments depends on the screw device installed on the housing.

5. The hammer is the key operating part. Its quality, shape and material have great influence on the output of crusher. Therefore, the appropriate hammer quality is selected by different feeding sizes. The hammer is made of wear-resistant steel pipe and hot polymer material, which is more than 3 times of the service life of general alloy steel hammer!

To sum up, this is the answer of hammer crusher. I hope the answer is what you want, but there are some shortcomings. Welcome to comment on them and discuss with them. Your praise is my motivation. Thank you.
