Hammer crusher

I. Profile

Hammer crusher is one of the main types of equipment to crush limestone, coal or brittle materials of below medium hardness in industrial departments such as metallurgy, building material, chemical, as well as water and electricity. It has characteristics including big crushing ratio, high production capacity, uniform particle size of crushed products etc.

Our company has now been engaged in the design and production of hammer crushers for more than thirty years. Our products are characterized by advanced product structure, smooth operation and low energy consumption. Our company has manufactured a series of hammer crushers which are well received by users at home and abroad.

II. Work Principle

Hammer crushers crush materials through impact. The crushing process is: When the materials get into the crushers, they crumble after impacted by the rapidly rotating hammer; the crumbled materials then gain kinetic energy from the hammer and run towards the baffle and grate bar at a high speed; at the same time, the materials crash into each other and are crumbled for many times; materials which are narrower than the gap between grate bars get out from the gap while larger materials crumble after impacted, grinded, and extruded once again on the grate bar before they are squeezed out from the gap by the hammer, so as to get products of needed particle size.

Hammer crushers are divided into reversible ones and non-reversible ones. The rotors of reversible hammer crushers are reversible. Such hammer crushers are normally used for fine crushing. The rotors of non-reversible hammer crushers are non-reversible. Such hammer crushers are normally used for intermediate crushing.

III. Main Structure

Such hammer crusher is mainly composed of the frame, rotor, grate bar, beater plate, adjusting device, etc.
