Hammer crusher is the most common of stone crushing equipment. It is also called hammer mill. It has high production capacity, low energy consumption, simple structure, reliable quality, easy maintenance, etc.
The main working part of the hammer crusher is the rotor with the hammer (also known as the hammer head). It is smashed by the blow, impact, shearing and grinding of the high-speed hammer. In the lower part of the rotor, there is a sieve plate, and the particle size smaller than the sieve hole size in the crushed material is discharged through the sieve plate. Hammer crusher is suitable for crushing minerals of various brittle materials. The crushed materials are coal, salt, white Asia, gypsum, alum, brick, tile, limestone, etc. The compressive strength of the hammer crusher material is not more than 100 MPa, and the humidity is not more than 15%. It can be used as crushing equipment for stone crushing, stone crushing, mine crushing, plastic crushing, garbage crushing and other materials.
Hammer crusher is a kind of equipment for crushing materials in the form of impact, which is divided into two forms: single rotor and double rotor. It is a one-stage crusher that directly crushes materials with a maximum particle size of 600-1800 mm to below 25 or 25 mm. Hammer crusher is suitable for crushing medium hardness materia.
How it works
Hammer crushers mainly rely on impact energy to complete the operation of crushing materials. When the hammer crusher is working, the motor drives the rotor to rotate at a high speed, and the material enters the crusher cavity evenly. The high-speed rotating hammer head rushes to the baffle plate and sieve bar in the frame, and the material larger than the sieve hole size is blocked on the sieve plate and continues to be hit and ground by the hammer until it is crushed to the required discharge size and finally discharged out of the machine through the sieve plate .
The advantages of hammer crusher are: large crushing ratio (usually 10-25, the highest is 50), high production capacity, uniform product, less powder phenomenon, low energy consumption per unit product, simple structure, light equipment quality, easy operation Easy maintenance etc. Hammer crusher series products are suitable for crushing various medium hardness and brittle materials, such as limestone, coal, salt, white, gypsum, alum, brick, tile, coal gangue, etc. The compressive strength of the crushed material shall not exceed 150 MPa. This machine is mainly used in industries such as cement, coal preparation, power generation, building materials and compound fertilizers. It can crush raw materials of different sizes into uniform particles to facilitate the processing of the next process. The mechanical structure is reliable, the production efficiency is high, and the applicability is good.
