Hammer Crusher Crushing Equipment SINOMALY
The hammer is designed with an entire rotation function, so the material impact on the rotor is significantly decreased. The crushing chamber is adjustable, thus reducing abrasion on wearing components. Reduced power parameters of the drive of ham- mer crusher DMRiE 14.5×13 for production conditions of fractional preparation of charge are recommended.

Hammer Crusher Parts, What You Need to Know
Rotor. The rotor is an important part of the hammer crusher. The rotor is mainly composed of a main shaft, a hammer disc, a pin shaft and a hammer head. There are evenly distributed pin holes on the disc, and the hammer head is suspended by a pin shaft. The axial movement of the head is fixed on the 2nd end of the pin shaft with a lock nut.The single-rotor hammer crusher is mainly composed of main frame, rotor, main shaft, hammer heads, grate, adjusting frame, and coupling. The shell of the hammer crusher is a box-shaped structure welded with steel plates, divided into upper and lower parts along the center of the axis, which are connected by bolts, and there is a feed Hammer Crusher Henan Deya Machinery Co., Ltd.

Design and Analysis of Rotor Assembly of Hammer Mill
When feed is delivered to the hammer mill crusher, it is prepared for cyclone furnace firing by being N = Speed of the shaft in rpm, 1728 rpm = (3.73 × 103 × 60) 2𝜋× 1728 1 .5 ×1 635 106 2+ 1 ×20.6128 103 2 = 47.684 I I Diameter of main shaft (d) should be equal to or more than d=47.684 mm Mass of Therefore we have rounded upIt can have difficulty breaking small parts, as the crusher’s ability to break blocks is related to the energy accumulated by the stone upon impact with the hammer. This energy therefore depends on the speed of the hammer, but also on the mass of the stone. Wear of the beaters depends on the matter being crushed.Choosing the right crusher Buying Guides DirectIndustry
