Basic information 

Hammer Crusher Introduction
 
electric hammer mill for stone, small coal hammer mill crusher ---hammer crusher also called hammer mill crushes by the collisions between high-speed hammer and material, which features in its simple structure, high reduction ration, high efficiency, ect. The hammer crushers were developed for the both dry and wet crushing of brittle, medium-hard materials for the mining, cement, coal, metallurgic, construction material, road building, and Petroleum & Chemical industries.

• Application area: mining, construction, metallurgy, chemistry, cement, coal
  Processing stage: primary crushing
  Crushing material: Coal gangue, coke, slag, limestone, phosphate rock, salt, whiting, gypsum stains, alum, brick and tile, calcite, bauxite, granite, iron ore etc. (<100Mpa)
  Main components: frame ,rotor, grizzly bar, Impeller bar,and other adjustment equipment
  Quickwear parts: high manganese steel

  

hammer mill benefits :
 
1.High production and high crushing ratio.
2Low power consumption, homogeneous particle size.
3.Simple, compact and light mechanical structure.
4.Low investment cost, easy management.
hammer mill application:
 
electric hammer mill for stone , small coal hammer mill crusher ---hammer crusher is applicable for both dry and wet crushing, and it is widely used for medium or fine crushing for medium hard and brittle materials by departments of mine, cement, coal, building material, metallurgy, chemical industry, road construction, gas chemical industry and thermal power generation, etc. Coal gangue, coke, slag, limestone, phosphate rock, salt, whiting, gypsum stains, alum, brick and tile, etc. can be crushed by this equipment. The compression strength of the materials shall not exceed 100MPa, while the moisture content shall be lower than 15%.

hammer mill working principle
The main working part of hammer crusher is rotors with hammer. The rotors consist of main shaft, disk, pin shaft and hammers. The motor drives the rotors to rotate quickly in the crushing cavity. Raw materials enter the crusher through the feed opening and are stricken, impacted, cut and ground by the high-speed hammer to small size. There is a screening plate under the rotor, so that materials with size smaller than the screen mesh will be screened out and others are left to be further hammered and ground until reach the standard size. The size of the final product can be adjusted by changing the screening plate. The gap between the rotors and the screening plate can also be adjusted according to different requirement.

Technical dataWorking Principle
Indicative Product Gradation Hammer crusher is composed mainly by the frame, rotor, impact iron bar, grid bar and other components. The frame consists of upper and lower parts, which are welded together after cutting by a steel plate, the remaining parts connected into a whole by bolts. There is high manganese steel liner inside the frame to facilitate replacement after worn. There are array of regularly distributed hammer bars on the spindle, which composed rotor together with rotary table and the shafts through the bar. The spindle is driven by the motor and V-belt, which promotes the rotor to rotate Centrifugal force produced when rotation makes the hammer stretch around. When the big materials get into the crushing cavity, they are crushed by the high-speed rotating hammers, the crushed products which meet the required size can be discharged from the sieve plate and become the final products, the products with larger size are brought back to the crushed area for being re-crushed, hit by a hammer and iron bar repeatedly, until they reach the required size. To avoid clogging, the water content of crushed material is generally not more than 20%.
The gradation and capacities shown are dependent on the feed gradiation, the crushing chamber, the material density, cleanliness, moisture and crushability
