Is Hammer Crusher Same As Impact Crusher?

Hammer crusher and impact crusher are common crushing equipment. There are great differences in their working principle, equipment structure, applicable materials, application industry fields. Commonly used in ore, gravel and other materials crushing and crushing. Both have received a wide range of popular models in mining equipment. So how to choose the right crushing equipment?

Working principle and component parts:

Hammer crusher its crushing chamber is using multiple hammer heads, through the high-speed rotation of the hammer head on the material for rapid striking. Thus achieve the crushing of materials. The bottom is equipped with a screen to control the particle size of the material.
Impact crusher has 2-3 impact plates, through the adjustment of the gap between the rotor plates and hammers to control the size of the discharged material. The plate hammers on the rotating rotor are fixedly installed on the rotor. When crushing, the impact and crushing of materials is achieved through the inertia of the whole rotor.

Is Hammer Crusher Same As Impact Crusher?

Applicable materials:
Hammer crusher is suitable for handling materials with medium hardness or above. For example: limestone, coal, gangue and so on. Ore and other materials with crushing strength of 200 MPa or less. It should be noted that the material can not contain a lot of water.
Impact crusher can handle soft materials or materials with great hardness. Just like granite, river pebbles, cobbles, basalt and other high hardness materials. Even the materials with large water content. But pay attention to the clogging problem.

Discharge particle size and shape:
The product of the hammer crusher after crushing has a lot of flakes and uneven processing shape. Its crushing process may produce a certain amount of dust.
Impact crusher finished product is cubic granular. Its discharges are more uniform. In some cases, a higher degree of fineness is also required for suitable applications.
