CE Certificated Stone Gravel Crushing Machine For Sale:

Production capacity:30-290t/h

Feeding size:≤ 190mm

The high efficient  gravel crushing machine  as a new fine crusher has a wide range of applications with the advanced international technology. It is the most effective and reliable crushing machine at present which is applied to do fine crushing and medium crushing of grinding materials, refractory materials, cement, silica sand and steel shot.

These series of impact fine crushers are designed for crushing ores and rocks with particle size no more than 500mm and compression strength no more than 320MPa. They enjoy features of high crushing ratio, high-efficient crushing, cubic shape of product, alternative crushing, etc. and they are ideal aggregate processing widely used in expressway, hydropower construction, airport and building industries.

gravel crushing machine  Working Principle:

materials entering the fine impact crusher cavity successively fall on the high speed spinning hammer and get crushed for the first time at the hammering zone under the action between the hammer and counter board. After high-frequency hammering and striking, materials fall on the median septum piling up and then they slide down on the bottom dumping disk of the high speed spinning rotor. Then materials are thrown to the impact plate at high speed and then are enforced to be impact, crushed and ground when passing the mobile board hammer. Therefore, materials are repeatedly crushed, washed and ground under the gravity action, thus realizing the fine crushing process.

Advantages and features of the gravel crushing machine : 

1.Discharging granularity is adjustable.

　　2.Sieve plate adopts special spring concession structure, simple, convenient, reasonable, safe and stable.

　　3.Adopt elasticity constant force and make crushing force stable.

　　4.Adopt high alloy hammer head, it can reduce abrasion, extend lifespan, and has high efficiency.

　　5.Mixing pad can exchange, also can increase the lifespan. Do not block and it has high safty.

　　6.Compared with hammer crusher and impact crusher, it can only wear rotor, and can not wear wheel core and hammer carrier.

　　7.It is easy to maintain, we only need to hoist the upper box, and open the lower box.

　　8.Adopt multi-layer three channel discharging device, it can discharge the material at time, and improve the capacity.

　　9.Adopt solid rotor, rotational inertia, and strong hitting power.
