Small Hammer Crasher Features and Benefits:

The main working part of hammer crasher is rotors with hammer. The rotors consist of main shaft, disk, pin shaft and hammers. The motor drives the rotors to rotate quickly in the crushing cavity. Raw materials enter the crusher through the feed opening and are stricken, impacted, cut and ground by the high-speed hammer to small size.

Small Hammer Crasher Working Principle:

Hammer crasher consists mainly of frame, rotor, hammers and grizzly bars and other components. The frame includes upper part and lower parts, which are welded by steel plates after cutting, the remaining parts bolted into one. High manganese steel liners are studded with inside the frame, to facilitate replacement for a new liners after worn; on the main shaft are installed several groups of the spindle distribution of the hammers, which consists of rotor with the axle of hammers and rotary table.

1.The host drives the main shaft through the motor and V-belt driven spindle to rotate the rotor, generating the centrifugal force, then driving all hammers stretch around.

2.The bulks of material feed into the crushing chamber, will be crushed by the hammers at a high-speed movement.

3.The broken material requested will be passed the grizzly bars at the lower part and discharged, the unbroken rest will be left in the chamber to be crushed repeatedly by the hammers and iron plates until it can reach the requested standard.

4.To avoid clogging, the water content of the material to be crushed not more than 5%.

Techniques of selecting hammer head:

 

Hammerheads are the main parts of hammer crusher. When buying hammer crusher equipment, you can select wear hammerheads of high quality through the following five aspects:

 

1.Material of the hammerhead

 

2.Structure design of the hammerhead

 

3.Manufacturing process of the hammerhead

 

4.Technical parameters of the hammer crusher

 

5.The feeding situation of the hammer crusher

 

 

 

The basic principle of choosing hammer head is: small hammer head with high chrome complex, big hammerhead with high manganese steel. Corrosive materials are not suitable for forging hammer head. The service life of hammerhead is different according to different cement plant and crushing plant of different region. At present the hammerhead with the longest life expectancy on the market is the one inlaid tungsten titanium carbide blocks.

 

 

How to judge the failure of the hammerhead:

 

The surface and edge of hammerheads are not worn when they first put into production. Hammerheads mainly bear impact. Materials impact the hammerhead surface with the forward force so that the hammerhead appear deformation and bump. After the wear and tear, the bearing surface of hammerhead surface is decomposed. The opposite force of the hammerhead surface will produce impact force on the hammerhead. And the tangential force will put the cutting force on the hammerhead. This directly caused the decrease of impact force in the crushing process, the reduction of production efficiency, and the increase of the broken time. Therefore, it indicates that the service life of the hammerhead may be over once the hammer force transfers and the hammerhead abrasion action begin to change.
