Impact crusher hammerhead structure design, life and movement principle analysis (Yifan machinery )

Impact crusher hammer crusher as core part, is arranged in the hammer crusher rotor shaft, hammer crusher is running at high speed in a direct blow to the material, finally breaking into the appropriate granularity.

Types of hammerhead

Jaw Crusher http://www.stonecrusher.org/CrushingMachinery/Jaw-Crusher.html

High manganese steel hammer, high chrome alloy hammer, carbide hammer.

The structural design of the hammer

Different structure and geometry of the hammer, the mechanical properties of the heat treatment, the microstructure of the interior of a great difference, and thus had a greater influence on the wear resistance, especially the thickness, and size of the hammer impact is more prominent . Hammerhead Heavy, the more difficult to quench

Through its anti-wear performance is also worse.

The life of the counterattack hammer crusher

Hammerhead's life not just related to the material of the impact crusher, impact crusher technical parameters, only the power and speed of the rotor body jump best to make it the longest life expectancy. Of course, a good shock hardening hammer service life potential

Must be longer than the average.

The hammerhead movement principle analysis

Divided into two cases according to the size of the hammerhead quality, the hammerhead quality infinity and hammerhead quality limited value.

The hammerhead quality infinity

Figure 1 plane - ball impact collision finite element model established in this paper. When the hammer bit rightward movement at a certain speed, the right side surface of the sphere to impact. Brittle materials by plastic deformation after impact is very small, so you can use linear elastic constitutive model mode.

The contemplated rock. Generally speaking, hammerhead material modulus of elasticity of the material 2 to 6 times, and for the crusher, the quality of the hammer plate 40 to 60 times the material quality. Therefore, you can think that the the hammerhead quality infinity.

The hammerhead quality limited value

In fact, the impact crusher rotor mass is not infinite, and hammer crusher, hammer typically only the quality of material quality? 5 to 2 times. Therefore, it is necessary to study the impact on the the hammerhead quality of the impact time.
