The purpose of refractory material screening is to remove impurities and unqualified products by fine screening of raw materials to ensure that the quality of the produced refractory materials meets the standards and can meet production needs.

Material characteristics: Refractory materials are an important material used in high-temperature industrial equipment. In order to ensure its use effect and life, refractory materials need to be screened and selected.

Scope of application: Refractory materials.

Purpose of screening: impurity removal and classification.

Problems of refractory material screening:

After crushing, fine grinding, screening and impurity removal, refractory raw materials are generally stored in storage bins for batching. The biggest problem of powder storage in the silo is particle segregation, because the powder particles are generally not a single particle size, but are composed of continuous particle sizes from coarse to fine, but the ratios between the particle sizes and particle sizes of various powders are different. When the powder is unloaded into the silo, the coarse and fine particles begin to stratify, the fine powder is concentrated in the central part of the discharge port, and the coarse particles roll to the periphery of the silo. When discharging materials from the silo, the materials in the middle flow out of the discharge port first, and the materials around flow to the middle as the material layer descends, and then flow out of the discharge port, causing particle segregation. At present, there are mainly the following methods to solve the particle segregation of storage silos in production: 1. Multi-stage screening of powder materials to reduce the difference in particle size of powder materials in the same silo. 2. Adding feeding ports, that is, multiple feeding ports. 3. Separating the silos.
