Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] Such as Figure 1~4 As shown, a metal crushing equipment includes several crushing units, the crushing unit includes a crushing device and a cooling device arranged below the crushing device, the crushing machine includes a shell 10, and a feed material is placed above the shell 110 The bucket 111 has a discharge port 112 at the lower part of the housing, and a pair of crushing rollers 120 that rotate in opposite directions are fixed in the middle of the housing 10 .

[0022] The crushing roller 120 includes a rotating shaft 121 driven by a motor, and the rotating shaft is covered with a fixedly connected roller 122. The rotating shafts of the two crushing rollers 120 can be fixed with gears that mesh with each other, so that when one of the rotating shafts 121 rotates, The synchronous rotation of the two drums 122 can be real...

Abstract

The invention provides metal crushing equipment and a production technology thereof. The metal crushing equipment comprises a plurality of crushing units which comprise crushing devices and cooling devices arranged behind the crushing devices. A crushing machine comprises a shell, and a feeding hopper is arranged on the upper portion of the shell. A discharging opening is formed in the lower portion of the shell, and a pair of crushing rolls which rotate oppositely is fixed to the middle of the shell. The cooling devices are arranged in a cover body, and a wind-distribution plate is arranged in the middle of the cover body. A plurality of evenly-distributed ventilating holes are formed in the wind-distribution plate. A wind inlet is formed in the lower portion of the cover body, and a windoutlet is formed in the upper portion of the cover body. The structure is simple, cooling of crushed metal materials can be conveniently achieved by utilizing the air cooling devices, the self-tempering phenomenon is avoided, and the material hardness is reduced.

Description

technical field [0001] The invention relates to metal crushing equipment and its production process. Background technique [0002] Alloy steel sand uses bearing steel scraps as raw materials. After quenching, it needs to go through multiple crushing processes. During the crushing process, the materials are extruded and rubbed against each other to generate heat, which makes the temperature of the materials rise greatly, resulting in self-tempering phenomenon, the hardness of the materials decreases, and continuous crushing. When the material is easily deformed and bonded, it also increases the number of tiny cracks in the broken product and reduces the physical properties. Contents of the invention [0003] The present invention improves the above problems, that is, the technical problem to be solved by the present invention is that the increase in material temperature in the existing metal crushing process is likely to cause tempering, resulting in a decrease in physical ...
