The hammer mill is the best known and by far the most widely used crushing device employing the impact principle of breaking and grinding stone. Thus far we have described machines which do a portion of their work by impact, but the only machine described in which this action plays an important role was the sledging roll type and particularly the Edison roll crusher and in these machines impact is supplemented to a substantial degree by a positive and powerful sledging action by teeth which are rigidly attached to massive rolls.
Hammer lip speed spans 26 to 33 m/s depending on the material and process . the hammer rotor; Heat from the kiln preheater exit gas is recycled for drying . construction houses no elaborate parts, thereby increasing hammer mill drier.
In an experiment that uses jaw crusher crush gangue, screening the crushed gangue and measure the calorific value. It is generally found that the calorific value is inversely proportional to the number of breakages. The more broken coal gangue is, the lower the calorific value is.
Unlike the jaw crusher, the material particle size after double roller crusher crushing and extruding is fine. There is no regular change in the calorific value of various particle sizes after sieving. Due to the specific crushing mode of roll crusher, the material crushing is more adequate. If crusher the coal waste which is more easily crusher, all the components will be crushed to smaller particles. The high-heat materials will not be an effective classification, and the separation effect is not good.
Compared with the jaw crusher and roller crusher, the impact crusher has a better crushing effect. The particle size of the broken gangue has an obvious inverse relationship with the calorific value. Gangue is the impact crusher by the hammer, the gangue itself, the impact plate repeatedly impact. In many times of impact, the gangue first from the brittle high and structure of the place broken. So the impact crusher has the other two crushers without characteristics of selective crushing. The separation effect is better than the jaw crusher and roller crusher.
The ring hammer crusher impacts the material with a movable hammer which causes the material to collide with the hammer body, the crushing plate, and with each other, then to be crushed. It is roughly the same as an impact crusher. The difference is that the crushing cavity of the ring hammer crusher is smaller. The ring hammer crusher can also adjust the size of discharge by changing the sieve plate with different sieve aperture.
The coal waste particle after crushed by a single-stage hammer crusher, the smaller the particle size, the bigger the calorific value, and the inverse relationship exists between the two. The calorific value of particle which less than 4.75 mm is larger than raw coal gangue. Therefore, it is feasible to separate the broken calorific value of coal gangue.
However, the proportion of particles which larger than 4.75 mm was higher, and a lot of uncrushed coal gangue. So, it can be seen that the crushing effect of this process is not good. The reason is that the size of the washed gangue is not largeusually less than 200mm. But the ratio of crushing of single-stage hammer crusher is large, crushing materials are generally larger than 600 mm. Therefore, some coal gangue will leakage from the hammer body after it from the inlet into the machine internal.
The crushed coal gangue which crushes by impact crusher, the small and big size is more, and the medium particle size is less. It also shows that the rocks in which harder mill and low calorific value are not excessively broken into powder,mass which is hard to be crushed and has low calorific value is not excessively broken into powder. The separation effect of coal gangue with high calorific value is better.
The upper part of the new coal gangue crusher is an umbrella-like structure, and the top part is provided with feeding holes. When the material enters the equipment, the gangue will be evenly dispersed by the distributing device, and the coal waste can also be temporarily stored in the middle space of the distributing device.

Heavy hammer crusher is used for crushing a variety of medium hardness and brittle materials which compression strength not exceeding 150 MPa, such as limestone, coal and other materials.
Mainly used in cement, mining, coal preparation, power generation, chemical and building materials industry. The material can be adjusted according to demand, rough, medium and small, complete specifications multi-angle multi-edge to ensure compression strength. Especially suitable for highways, construction, and large-scale engineering materials.
It is called as reversible no-grate hammer crusher because its rotor is reversible without a grate. It solves the problem of crusher being blocked by wet material, improves hammer utilization ratio, reduces the frequency of hammer change and ensures uniform granularity of discharged material.
1. The heavy hammer crusher boulder broken with a large feed size, high yield, low energy consumption, simple structure, easy maintenance.
2. PCZ-type heavy hammer crusher broken stone, a molding, without more crushing process, you can reduce the cost of about 40, low energy consumption, less investment. Compared with the same output of the jaw crusher, can reduce the investment in equipment, with less investment fast.
3. The heavy hammer crusher with no grate design, for wet materials, soil and more broken raw materials, eliminating the clogging of the adhesion of the suffering.
4. The heavy hammer crusher with alloy composite hammer, reducing the consumption of wear parts, long service life reducing the production cost of about 35
1. Coal gangue will be used for electricity production after primary crushing by crusher mainly co-fire washed medium coal and washed gangue to generate electricity. The generally heating value is 3,500 kcal per kilogram 2.
For the Mosh hardness of coal is usually under 5, the miners can use jaw crusher, JC jaw crusher, hammer crusher, impact crusher, and hydraulic impact crusher etc. to handle it. After the coal has been crushed by coal crusher, we need vibrating screen to grade the coal by size and then transport the coal via belt conveyor.
