1、 Scope of application:
It is suitable for power, mining, metallurgy, chemical industry, coal, building materials and other industries. Materials with compressive strength <120mpa and containing certain fine materials (such as coal, coal gangue, shale, etc.) are screened first and then crushed. There is no requirement on the moisture content of materials, and there is no blocking discharge under high humidity and high viscosity conditions. The feed particle size is less than 400mm, and the discharge particle size is less than 8mm.
2、 Structure principle:
The screen breaking machine is composed of two parts: screening and crushing. The screening part is composed of a plurality of screen shafts and a driving device. The screen shaft is equipped with screen plates. The screen shaft is driven by a motor reducer to rotate in the same direction. The screen plates of adjacent screen shafts cross each other to form a screen gap; The crushing part is composed of a rotor and a counterattack plate. The rotor is equipped with a full rotation hammer head to ensure uniform wear of the hammer head and improve the utilization rate of the hammer head. The impact plate is divided into coarse impact plate and fine impact plate, which can crush 400mm blocks to less than 8mm at a time to complete the coarse and fine crushing of materials.
(1) Discharge granularity guarantee:
The consistence mechanism can adjust the gap between the fine breaking impact plate and the hammer head, so as to control the size of discharge particle size and ensure that the qualified rate of discharge particle size is 90-100%.
(2) feed granularity guarantee:
The adjustment mechanism can adjust the angle of the impact plate in the coarse broken area. To adapt to the size of feeding amount and feeding particle size. The maximum feeding particle size reaches 400 mm, and the material flow runs smoothly in the machine without blocking or jamming
(3) Convenient maintenance:
When the casing is opened, the hammer head, impact plate, side lining plate and other vulnerable parts can be replaced to reduce the labor time for replacing vulnerable parts.
3、 Performance parameters:
4、 Performance characteristics:
(1) the material preparation process is simple, the floor space is small, one machine is multi-purpose, and there is no need to design a separate screening floor.
(2) adapt to all kinds of raw coal, medium coal and low-quality coal; There is no requirement for the moisture of coal, especially under the condition of high moisture coal, high viscosity coal or high content of fine powder in materials;
(3) This all-in-one machine adopts the advanced design concept of "large screening and less crushing", with large processing capacity and screening efficiency of more than 90%. It is a real all-in-one screening machine; The concept of screening is effective, and there is really no
Repeated crushing; Reduce crusher load;
