In the current mines, the most used ones areHeavy hammer crusherHowever, this crusher is a kind of equipment with better performance. Its structure design is reasonable, the crushing force is large, the output is large, the overall performance is good, and the material is finely crushed. It is purchased by most mine users and is a relatively good product sold by major manufacturers.
Hammer crushers mainly crush materials through impact. The crushing process is roughly as follows: the material enters the crusher and is impacted by the high-speed rotating hammer. The crushed material obtains kinetic energy from the hammer head and rushes to the baffle and screen bar at high speed. At the same time, the materials collide with each other and break several times, which is smaller than the gap between the screen bars, and are discharged from the gap. Some larger materials are impacted, ground and crushed by the hammer on the screen bar again, and then squeezed out from the gap by the hammer. , So as to obtain the required particle size products.
The heavy hammer crusher can be divided into vertical crusher, horizontal crusher, single rotor crusher and double rotor crusher according to the structure type. A fixed screen is installed at most of the discharge. Users can choose a suitable aperture sieve to control the discharge particle size according to their needs. This type of crusher is suitable for crushing fragile materials, such as coal, shale, etc., but not for hard or viscous materials. The single-rotor crushing ratio is generally 10-15, and the double-rotor crushing ratio is 20-30. The moisture content of raw materials is relatively strict, generally no more than 8. If the moisture content is too high, it is easy to block the screen holes and not discharge. In order to reduce non-broken materials such as iron blocks and steel nails from falling into the crusher, the added materials need to be carefully checked to ensure that the unbroken materials are removed in time.
The heavy hammer crusher is mainly used for fine crushing of materials and is an important equipment choice in the field of fine crushing. Taking the fine crusher as an example, the hammer head is a split structure, and the hammer head and the hammer handle are connected by bolts. The hammer head material is a highly wear-resistant chromium molybdenum alloy. Among the hammer heads used, the wear resistance time of the hammer head is relatively long. The hammer head adopts a split structure, it is convenient to replace the hammer head.
What materials can hammer crusher equipment crush? Let us take you to find out that this equipment can not only handle different stone materials dry, but also wet crushing. Therefore, there is no requirement for the water content of the material. This equipment can be applied to different industry sectors such as mining, cement, coal and metallurgy.
