The influencing factors of hammer crusher hammer used

Hammer crusher is used in mining, chemical, metallurgy, building materials, electricity and other commonly used crushing equipment in the industry, and a hammer head as the main equipment is easy to wear parts, it is good or bad, and directly affects the service life of crusher crushing efficiency.

During the period of work, due to the impact of the hammer to hit and material of the dual role, after repeated use for a long time, hammer head face will be damaged, the surface shape changed, so need to be replaced frequently.

The influencing factors of hammer head:

1. The hammer head of structure design and the quality of the product

The structure design and shape of the hammer on the mechanical properties after heat treatment and internal microstructure has great influence. The main cause of hammer head fracture is the surface or the inner defects of different level. As a result of the existence of defects, make the most of the hammer head fracture occur at the beginning of the use.

2. The technical parameters of hammer crusher

Hammer crusher technical parameters can affect the service life of hammer, the main of which is the power and speed of the rotor.

3. The materials of the broken pieces and hardness

Material, the greater the block the higher requirements for its toughness, and the higher the material hardness, the higher the hardness of hammer head material requirements. The specific type of crusher should adopt appropriate feeding granularity, which to a certain extent, prolong the service life of hammer head.

4. The hammer crusher internal clearance adjustment

Hammer crusher is mainly refers to turn internal clearance daughter and back plate and the clearance between hammer head. The gap size, will be related to the discharge port, if there is a product of material near the exit.
