Description

Grinding device for improving roundness of raw material

Technical Field

Background

The refractory material is an inorganic non-metallic material with the refractoriness of not less than 1580 ℃, but the refractory material cannot be fully described only by the definition of the refractoriness, and the temperature of 1580 ℃ is not absolute. Materials that are now defined as materials whose physicochemical properties allow them to be used in high temperature environments are referred to as 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 materials include sintering methods, fusion casting methods, and melt blowing methods, depending on the degree of densification and the shape of the product. 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. In order to homogenize the components and particles of various raw materials and clinker, mixing is carried out, and simultaneously, a binding agent is added to enhance the binding strength of the raw materials. For example, the aluminium silicate blank is added with binding clay, the magnesium blank is added with sulfurous acid pulp waste liquor, and the silicon blank is added with lime milk, etc. Depending on the amount of water content of the green material, semi-dry forming (about 5% moisture), plastic forming (about 15% moisture) and slip casting (about 40% moisture) may be used. And then drying and firing are carried out. The fusion casting method is that the raw materials are mixed evenly and ground finely, melted at high temperature, cast directly, cooled, crystallized and annealed to form the product. Such as cast mullite bricks, corundum bricks, magnesia bricks, and the like. Their green bodies are compact, their mechanical strength is high, high-temp. structural strength is large, slag-resisting property is good, and their application range is continuously enlarged. The melt blowing method is a method of melting the ingredients and then blowing the melted ingredients with high-pressure air or superheated steam to disperse the melted ingredients into fibers or hollow spheres. The product is mainly used as light fire-resistant and heat-insulating material. In addition, the refractory material may be produced into powder or granular unshaped refractory material, which is cemented with tar, asphalt, cement, phosphate, sulfate, chloride and other binding agent before use and is used directly without forming and sintering.

In the preparation process of the refractory material, grinding is needed to improve the roundness of the raw material (calcined aluminum hydroxide powder) so as to improve the quality of subsequent granulation, and the common grinding adopts the sieving and rotation of a mesh screen to make the material perform rolling friction, so that the grinding mode not only needs long time, but also has low grinding quality.
