Novel powder manufacturing apparatus and process

Abstract

The invention discloses a novel powder manufacturing apparatus and process. The novel powder manufacturing apparatus comprises a transporting machine, a screening machine, a distributing device, a distribution bin, a feeding device, a grinder, a discharging device, a conveyor and a filler bin. The powder manufacturing apparatus is characterized in that a discharge port of the transporting machine is connected with an inlet of the screening machine, an upper outlet of the screening machine is connected with the distributing device, the distributing bin is connected with the screening machine through a distributing pipe, an outlet of the distributing bin is provided with the feeding device, the feeding device is connected with an inlet of the grinder, an outlet of the grinder is provided with the discharging device, the discharging device is connected with the conveyor, an outlet of the conveyor is connected with an inlet of transporting machine, and a lower outlet of the screening machine is connected with the filler bin in which fillers unnecessary to crush are stored. The unique feature of the novel powder manufacturing apparatus is that the grinder is used for directly processing massive materials, and thus various bad results caused by crushing and grinding processes are avoided; and qualified materials produced by each crushing action are immediately screened out, and cannot be crushed into unqualified materials again.

Description

[0001] technical field [0002] The invention belongs to the field of crushing and grinding, and in particular relates to a novel milling equipment and process method. Background technique [0003] The present invention uses a crushing and grinding machine (abbreviated as a crushing machine) to realize the integration of crushing and grinding functions. The basic principle of the crushing machine is to use two working plates to form a crushing chamber with a certain opening, or to use multiple working plates to Multiple crushing chambers are formed. After the material enters the crushing chamber, the working plate is subjected to the unidirectional uniform pressure of the outside, so that the distance between the working plates is reduced and the materials in the crushing chamber are crushed at the same time. The limit device between the adjacent working plates can avoid the adverse effects of crushing and grinding caused by the material no longer being squeezed. After the m...

AI Technical Summary

Problems solved by technology

[0005] The disadvantages of the above milling equipment are: (1) The bulk materials need to be processed by the crushing equipment before entering the grinding equipment for processing. The crushing and grinding processes are separated in the whole processing process, and there are many material transfer links. The demand is large, the failure rate is high, and it is difficult to form a long cycle of production. At the same time, it is difficult to match the crushing and grinding equipment with each other, and it is prone to equipment emptying, and the milling efficiency is low.

(2) During the crushing and grinding process of the material, the friction between the material particles and between the material and the roller is serious, and the volume ratio of the compressed material is too large, which is easy to cause extrusion into blocks, excessive unqualified fine powder and controllable particle size (3) The material is subjected to various forces during the working process, the particle size distribution is wide, and the controllability is low; (4) It is easy to cause over-crushing during the crushing process and over-grinding during the grinding process; (5) ) during the crushing process, the self-grinding phenomenon is serious, and qualified materials are easily crushed again or repeatedly, and the self-grinding phenomenon is also serious during the grinding process, and qualified materials are easily ground again or repeatedly, resulting in unqualified ultrafine powder (6) Due to the low controllability of most crushers, the crushing area of ​​the crushing body is unevenly stressed and severely worn; (7) When crushing and grinding materials, the materials are easily impacted, and when dealing with explosive materials low security
