Abstract

The invention relates to the field of recycling of stone waste, provides a method of recycling waste stone dust and solves the problem that the prior art recycling method requires use of massive water, leading to waste of water resources.The method comprises the steps of waste stone material collecting, drying, pulverizing, cooling, and screening and cleaning; in the drying step, heating temperature for the waste stone material is controlled to 100-103 DEG C, and drying time is controlled to 30-60 min; in the screening and cleaning step, stone dust 400-500 meshes in particle size is screened out.

Description

Technical field [0001] The invention relates to the field of stone waste recycling and utilization, in particular to a method for recycling waste stone powder. Background technique [0002] A large amount of waste materials are generated during the processing of stone, mainly including scrap and stone powder. Among them, the stone mainly produces a large amount of small particle size stone powder during the cutting process. The solid matter formed after the stone powder is collected and solid-liquid separated contains a certain amount of water. There is no better treatment method for these stone powders. They can only be piled up. If only the stone powder is piled up, it will cause waste of land and resources, and it will pollute water sources and cause great harm. Therefore, how to deal with and use these stone powders and turn waste into treasure has become an issue of great concern to stone enterprises. [0003] Chinese Patent Application No. 201410544170.6 discloses a method f...
