mechanical grinding system
1、 Product introduction
Hammer crusher is suitable for crushing heavy hardness and brittle materials in mining, cement, coal, metallurgy, building materials, highway and other industries. The material structure is simple and the crushing ratio is large through the high-speed rotating hammer and material crushing. High productivity. Can be dry and wet, two forms of crushing. The advantages of hammer type double function crusher: large crushing ratio (generally 10-25, up to 50), high production capacity, uniform products, less over crushing phenomenon, low energy consumption per unit product, simple structure, light equipment quality, easy operation and maintenance, etc.
2、 Performance characteristics
1. Suitable for many materials and large operation space
Hammer crusher series products are suitable for crushing a variety of medium hardness and brittle materials, such as limestone, coal, salt, Baiya, gypsum, alum, brick, tile, coal gangue, etc. the compressive strength of crushed materials is not more than 150 MPa. It can be used in cement, coal preparation, power generation, building materials, chemical industry, metallurgy and compound fertilizer industries.
2. The design of hammer head is reasonable and the work efficiency is high
The hammer crusher adopts high manganese steel and passes through strict heat treatment process to obtain single austenite structure. The service life of hammer crusher is longer than that of other crushing equipment, and the production efficiency is also better than ordinary equipment.
3. Energy saving and consumption reduction of triple crushing
The crushing mode of hammer crusher is that the energy drives the hammer head to break, and then the material hit by the hammer head collides with the impact plate at high speed, and then the stone of the impact plate collides with the material hit by the hammer head. There are three crushing forces, but only those energy driving the hammer head are consumed, so the hammer crusher can save energy and reduce consumption.
4. Stable operation and high crushing ratio
The design of hammer crusher is beautiful in appearance and compact in structure. Each part is strictly screened and checked, which can realize normal operation for a long time. Moreover, the crushing ratio is large, and the particle size of the product is uniform. Generally, it is cubic shape, and there is no excessive crushing phenomenon.
3、 How it works
Hammer crusher mainly relies on impact to break materials. The crushing process is roughly like this: materials enter the crusher and are crushed by the impact of high-speed rotating hammer head. The broken materials obtain kinetic energy from the hammer head. At the same time, the materials collide with each other and are broken many times. The materials smaller than the gap between the screen bars are discharged from the gap. A few larger materials are crushed by the impact, grinding and extrusion of the hammer head on the screen bar again, and the materials are extruded from the gap by the hammer head, so as to obtain the products with the required particle size. Hammer crusher is divided into reversible and irreversible two types, reversible hammer crusher rotor reversible, generally used for fine crushing; irreversible hammer crusher rotor irreversible, generally used for intermediate crushing.
