Abstract

The invention discloses a crushing and screening device for materials. The crushing and screening device is characterized by comprising a charge device, a crushing device and a screening device, wherein the charge device is communicated with a shell; the crushing device is arranged in the shell, and provided with a filter screen at the periphery; and the screening device is located below the crushing device. Preferably, the materials are alloy sheets; the charge device comprises a charge nozzle and a loop from the filter screen to the charge nozzle; an inert gas inlet is arranged in the top of the charge nozzle and the bottom of a stainless steel elbow pipe respectively; the crushing device is provided with a drive motor; the screening device is provided with a vibration motor; the drive motor is a special frequency conversion motor; and the special frequency conversion motor is controlled by a frequency converter. The crushing and screening device disclosed by the invention is simple in structure, simple and convenient to operate overall, stable and reliable in running, low in noise, less in raising dust, good in field environment, and capable of effectively preventing frictional sparking generated by ultrafine powder grains with a pipe wall during a high-speed rotation process, thus safety performance is greatly improved.

Description

technical field [0001] The invention relates to a crushing and screening device for materials, especially a crushing and screening device for metal materials, in particular, the invention relates to a crushing and screening device for alloy flakes. Background technique [0002] At present, various types of crushers widely used in industrial production include jaw crushers, chain crushers, hammer crushers, ordinary roller crushers, etc. Although these equipments have their own application fields, they also have many shortcomings. . For example, these equipments all have the problem of needing a coarse crushing process before they can be further finely crushed. They have the disadvantages of long crushing process, many equipments, poor environment and high cost, and are not suitable for crushing metal materials such as alloy flakes. [0003] There is no effective crushing and screening machine for alloy flakes in the prior art. Contents of the invention [0004] The purpos...
