Powder metallurgy raw material crushing machining process

Abstract

The invention relates to a powder metallurgy raw material crushing machining process. The powder metallurgy raw material crushing machining process is completed by mainly utilizing a powder metallurgyraw material linkage crushing device in a cooperative mode. The powder metallurgy raw material linkage crushing device comprises a square cylinder, a primary crushing mechanism and a secondary crushing mechanism, wherein the lower end of the square cylinder is installed on an existing working ground, the primary crushing mechanism is installed at the upper end of the interior of the square cylinder, the secondary crushing mechanism is arranged right below the primary crushing mechanism, and the secondary crushing mechanism is installed inside the square cylinder in a sliding fit mode. According to the powder metallurgy raw material crushing machining process, metallurgical raw material crushing machining is carried out by adopting a design philosophy of a multi-stage cooperation crushingstructure, an auxiliary grinding structure is additionally arranged on the basis of adopting the primary crushing mechanism and the secondary crushing mechanism, so that the crushing degree of the metallurgical raw material is improved, and the percent of pass of metallurgical raw material crushing forming products is increased; and meanwhile, a structure for recovering and retreating omitted metallurgical raw material or metallurgical raw material which is not ground is arranged, and therefore, the metallurgical raw material can be utilized to the maximum extent.

Description

technical field [0001] The invention relates to the technical field of metallurgical processing equipment manufacturing, in particular to a powder metallurgy raw material crushing process. Background technique [0002] Metallurgy is the process and technology of extracting metals or metal compounds from minerals, and using various processing methods to make metals into metal materials with certain properties. Metallurgy has a long history of development, from the Stone Age to the subsequent Bronze Age, and then to modern times. The large-scale development of iron and steel smelting, the history of human development has integrated the development history of metallurgy. Metallurgical technologies mainly include pyrometallurgy, hydrometallurgy and electrometallurgy. With the successful application of physical chemistry in metallurgy, metallurgy has moved from technology to science. It is a process technology for producing metal powder or using metal powder (or a mixture of meta...

AI Technical Summary

Problems solved by technology

[0003] 1. When metallurgical raw materials are crushed by mechanical crushing methods, the crushing effect of metallurgical raw materials is often poor due to fewer or relatively simple crushing processes. The metallurgical raw materials are outside the working range of the crushing structure and cannot be effectively crushed, and the metallurgical raw materials are easy to accumulate on the edge during the crushing process, so that the utilization rate of the metallurgical raw materials is low;

[0004] 2. Part of the metallurgical raw materials or raw material powders that are easy to accumulate on the crushed structure and some other structures will affect the functions of the crushed structure and other structures after the accumulation of these metallurgical raw materials or raw material powders increases to a certain extent, and the remaining metallurgical Raw materials cannot be effectively recycled and reused, and the waste rate of metallurgical raw materials is high, resulting in increased production costs. At the same time, the concentration rate of raw material powder is low, which means edge accumulation is easy to occur, so that the final output of raw material powder is low
