How many categories are there in iron ore crushers?
The jaw crusher consists of two jaw plates of moving jaw and static jaw, crushing chamber, simulating the two jaw movement of animal, and crushing machine for crushing material. Widely used in mining, smelting, building materials, highways, railways, water conservancy and chemical industries, a variety of ore and bulk materials of medium grain crushing. The maximum compressive strength of the crushed material is 320Mpa.
Counter roll crusherThe medium coal roll crusher can effectively break the material to mm grade. However, the crushing ratio of the roller crusher is too small, and its feed range is greatly limited. The structure of the roller crusher is more complex and large, and the treatment of roller wear and the high cost of daily maintenance is an important factor restricting its development. In the large-scale crushing production of iron ore, its application is less.
fine crusherThe principle and suggestion of high efficiency fine coal crusher is the same as hammer breaking. However, the structure of the efficient fine crusher has been greatly improved. The hammer head adopts a combined structure, which can replace the hammer head conveniently; the bottom sieve plate adopts the casting structure, which makes the sieve plate have certain worn-out function. The overall structure is more intensive, and the production capacity has been greatly improved. Under the condition of less than 100 tons per hour, the production capacity of the single chip mill can be steadily carried out. When the single machine capacity exceeds 100 tons / hour, some problems of hammer fragmentation will gradually appear. For example: blocking material problems, wear problems, replace the wear-resistant parts of the workload is too large, and so on.
Coal cone crusher as a crushing equipment, the only shortage is the output and fineness of the contradiction. When we pursue smaller crushing fineness, we must reduce the eccentricity and discharge opening of cone crusher, which will greatly reduce the capacity of cone crusher. Therefore, the cone crusher is used as an iron ore crusher, and the crushing size is not fine enough. Have a certain influence on the operation of domestic ore dressing. However, the cone crusher's stable and reliable performance makes it widely used as the two grade crushing of iron ore.
Coal crusher is a new type of high-efficiency crushing equipment, which is characterized by small size, simple structure, high crushing ratio (up to 40), low energy consumption, high production capacity, product size uniform, and selective crushing effect, is a promising device. But its biggest drawback is that the hammer and the back plate are particularly easy to wear, especially the crushing of hard ore, wear is more serious, often need to change. Because of the emergence of some wear resistant materials, it has been applied in some metal concentrators.
