[0002] Refractory materials refer to a type of inorganic non-metallic materials with a refractoriness of not less than 1580°C. It is now defined as any material whose physical and chemical properties allow it to be used in a high temperature environment. Refractory materials are widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, silicate, power and other industrial fields. The largest amount is used in the metallurgical industry, accounting for 50% to 60% of the total output. Refractory materials need to be dried during the production process to facilitate the next step or storage. The existing refractory drying equipment has the defects of insufficient and uneven drying and low drying efficiency, which will affect the processing and use of refractory materials.

[0003] To this end, those skilled in the art have conducted research and improvements, such as the drying equipment for the production of refractory materials with application number CN202021023305.1. This technical solution can comprehensively tumble the refractory materials through its stirring mechanism, so that the refractory materials can be fully dried, and the drying efficiency is relatively high. Through its main mechanism, the stirring bin can be raised and lowered, so that the refractory materials can be quickly discharged, greatly improving production efficiency.
