Crushing and screening device for new raw material

Abstract

The invention discloses a crushing and screening device for a new raw material. The crushing and screening device comprises a crushing drum, an outer box body, a material collecting box and a supporting platform, wherein supporting leg assemblies are respectively arranged at four corners of the bottom end of the supporting platform; a rotating rod is fixedly welded to a right side plate of the crushing drum, and is rotatably erected on the right side plate of the outer box body in a manner of bearing connection; a servo motor is fixedly mounted on the upper surface of the right part of the topplate of the outer box body; a plurality of chains are fixedly arranged on the inner wall of an inner cavity of the crushing drum; and a plurality of crushing balls are uniformly arranged on each chain. The crushing and screening device disclosed by the invention is simple and reasonable in structure, and convenient to operate; the crushing effect for the new raw material is good; the new materials are convenient to collect; and besides, the crushing and screening device is good in shock absorption and buffering effect and has a high promotional value.

Description

technical field [0001] The invention relates to the technical field of new material processing, in particular to a crushing and screening device for new material raw materials. Background technique [0002] New materials refer to some materials that are newly developed or under research and development, and have superior performance, which have better performance than traditional materials. [0003] Screening is the process of using a sieve to make the fine-grained materials smaller than the sieve holes pass through the sieve surface, while the coarse-grained materials larger than the sieve holes stay on the sieve surface, thereby completing the process of separating coarse and fine materials. The separation process can be regarded as composed of two stages: material stratification and fine particle sieving. Material stratification is the condition to complete the separation, and fine particles suitable for sieving are the purpose of separation. [0004] In the production ...

AI Technical Summary

Problems solved by technology

[0004] In the production process of new materials, in order to improve the quality of new materials after production, it is necessary to crush and screen raw materials, and to screen out raw materials that are too large and difficult to process. At this time, it is necessary to crush and screen raw materials. The current raw material crushing and screening When the machine crushes and screens raw materials, it often occurs that the crushing is not complete and the screening effect is not good, which is inconvenient to use
