Description

Technical Field

[0001] The present invention relates to the technical field of grinding devices, and particularly to a grinding device for producing ceramsite sand from waste ceramic tiles. Background Art

[0002] As a part of construction waste, waste ceramic tiles are usually difficult to handle. By converting them into ceramsite sand, the environmental burden caused by landfill and incineration can be effectively reduced. Recycling and reusing waste materials in this way helps to achieve a circular economy of resources and reduce the consumption of natural resources. The process of producing ceramsite sand from waste ceramic tiles mostly involves crushing and grinding the waste ceramic tiles into small particles, then screening to ensure that the particle sizes are uniform and meet the requirements. Subsequently, the particles and clay are stirred and then sintered at high temperature to form pores inside the particles, and then gradually cooled to produce ceramsite sand particles. Traditional crushing and grinding of waste ceramic tiles mostly involve crushing by a crusher and then feeding the crushed materials into a grinding machine for grinding. The crushed materials need to be repeatedly recycled into the crusher for multiple crushing before they can be ground, which is rather troublesome to operate. Therefore, we propose a grinding device for producing ceramsite sand from waste ceramic tiles to solve the above problems. Summary of the Invention
