The board hammer abrasion of Mobile Combined Crushing Plant only can be found on the side of contacting materials. When the rotor operates at normal speed, the charge-in materials will fall onto the surface of board hammer ( attack side), and the back and flank side of the board hammer is not worn. And even the contacting side is rarely worn. Besides, the bottom of the grinding rod is also very easy to replace. The metal utilization of impact crusher board hammer can be as high as 45% -48%. However, that of usage of hammer crusher is just 25% or less. Because the hammer head of hammer crusher is in overhanging state. The abrasion is occurred on above side, front, rear side and flank side. Compared to board hammer, the hammer crusher is worn more serious. Furthermore, the rotor may also suffer abrasion. Once the bottom screen of hammer crusher wear too seriously, the grille should be replaced completely. And replacement is more complicated.

There are only six board Raymond Mill Manufacturerinstalling on the rotor of impact crusher, so that the board hammer can be replaced easily with tools. The replacement of a board hammer just spends a shift time. And the bottom grinding rob replacement only takes several minutes. That greatly reduces the time of repairment and cost of maintenance. However, hammer crusher has over 100 hammer heads. It spends a lot of time and labor source to replace a hammer. And the costs of repair and maintenance is higher. Moreover, the bottom screen replacement is extremely complicated.

Based on years of experience, PF Series Impact Crusher has been developed by our company. It is a kind of broken machine making use of impact energy to break the materials. When operating, the rotor will high-speed rotation driven by the motor. As the material come into the interaction region, they were broken by attacking with the plate hammer. And then the materials were thrown to the counter-attack on the device for crushing again. Finally, the materials bounced back into the interaction region to re-broken. This process is repeated and materials size from big to small through repeated broken in the first, second and third impact chamber until the material is broken to the desired particle size and out of the discharge port. Adjust the gap between the frame and the rotor can change the material particle and shape. Stone falls directly into the high-speed rotation of the turntable from the upper part of the machine; Under high-speed centrifugal force, stone shunts around the turntable with umbrella shape at high-speed. Under the collision with each other, stone will friction, grinding many times. Finally, finished products fall straight from the lower part of the discharge. Thus form a closed loop several times to reach the required particle size by sieving device control.
