Hammer Crusher

Working principle

When the hammer crusher or hammer crushing machine works, the motor drives the rotor to spin at high speed, materials are fed into the crushing cavity evenly, and then be impacted, cut and tore by high speed spinning hammerhead till they are completely crushed. Meanwhile, the gravity action of materials forces them to crash the baffle and grate bars on the frame. Materials with particle size smaller than the screen size will pass the sieve plate while those with bigger particle size are stopped on the plate and will continue to be impacted and grounded by the hammer until they are crushed to the required particle size, finally, crushed materials will be discharged from the hammer crusher through the sieve plate.

Introduction

Hammer crusher is suitable for the fine crushing of limestone, coal or other medium hard brittle materials in metallurgical industry, building materials industry, chemical industry and hydropower industry. Hammer crusher has several features such as big crushing ratio, high production capacity and uniform product size. Hammer crusher can crush the maximum size of 600-1800 mm materials into 25mm or below 25 mm size, so it is also known as crusher hammer or hammer mill crusher. Because it is often used for coal crushing in coal mines, it is also known as coal crusher.

Product advantage

1. The crushing ratio is large, the production efficiency is high, and the applicability is strong. The required particle size can be adjusted according to customer requirements.

2. There is no screen grate bottom, there is no requirement for the moisture content of the material, and there is no problem of blocking the screen plate

3. The overall design has the advantages of beautiful appearance, compact structure, few wearing parts, and convenient maintenance. It is an upgraded product.

4. The bearing box is all made of cast steel and fixed with four screws, which is scientific and practical; the working hammer head is cast by new technology, which is wear-resistant and impact-resistant.
