Description

Reducing mechanism is used in refractory material production

Technical Field

The invention relates to the technical field of refractory materials, in particular to a crushing device for refractory material production.

Background

Inorganic non-metal material with refractoriness not lower than 1580 deg.c. Refractoriness is the degree centigrade at which a sample of the refractory cone resists high temperatures without softening and melting down without loading. However, the definition of refractoriness alone does not fully describe the refractory material, 1580 ℃ is not absolute, and materials whose physicochemical properties allow them to be used in high temperature environments are called refractory materials. The refractory material is widely used in the industrial fields of metallurgy, chemical industry, petroleum, mechanical manufacturing, silicate, power and the like, and the use amount is the largest in the metallurgical industry, and accounts for 50-60% of the total output. The refractory material is applied to various fields of national economy such as steel, nonferrous metals, glass, cement, ceramics, petrifaction, machinery, boilers, light industry, electric power, military industry and the like, is an essential basic material for ensuring the production operation and the technical development of the industries, and plays an irreplaceable important role in the development of high-temperature industrial production. Depending on the degree of compaction and the shape of the product, there are sintering, melt-casting and melt-blowing processes. The sintering method is that part of raw materials are presintered into clinker, crushed and screened, then mixed with raw materials according to a certain proportion, and the mixture is formed, dried and sintered. The pre-sintering of the raw materials aims to burn out the water, organic impurities and gases decomposed by sulfate so as to reduce the sintering shrinkage of the product and ensure the accuracy of the overall dimension of the product. The raw materials need to be sieved after being crushed and ground, and because the blank is graded by powder with different particle sizes, the closest packing can be ensured to obtain a compact blank.

The existing refractory material crushing device cannot achieve the precision required by processing through primary crushing in the process of crushing production raw materials, and the raw materials which do not achieve the crushing precision are generally collected firstly and then subjected to same progressive secondary crushing, so that time and labor are wasted, and the raw materials which do not achieve the crushing precision also need to occupy the site for stacking.
