Process of manufacturing high-efficiency, energy-saving and environment-friendly desulfurized calcium powder by utilizing stone leftover material

Abstract

The invention provides a process of manufacturing high-efficiency, energy-saving and environment-friendly desulfurized calcium powder by utilizing a stone leftover material. The process comprises the following steps of: collecting the leftover material; drying; crushing; hermetically sieving; removing scrap iron impurities; canning for storage; performing variable frequency feeding and secondary impurity removal and setting up a mill; collecting granulated powder; and loading and transporting. The desulfurized calcium powder prepared by the process is high-efficiency and energy-saving, meanwhile, the problems of environmental pollution, land and woodland occupation and the like caused by random dumping of the leftover material are solved, and the aim of changing the waste material into things of value is fulfilled.

Description

technical field [0001] The invention belongs to the technical field of stone waste processing, and relates to a process for producing high-efficiency, energy-saving and environment-friendly desulfurization calcium powder by using waste stone corners. Background technique [0002] At present, in the deep processing of mineral mining in our country, such as the deep processing of stone, there are many corner wastes in the production process of enterprises. Since these corner wastes can no longer be reused in the production process of enterprises, in order to reduce the cost of daily waste treatment, enterprises often use These corner wastes are dumped on roadsides, fields, slopes, rivers, etc., and even piled on farmland, causing land and forest land to be occupied. And these corner wastes often cause surrounding environmental pollution along with the effect of wind and rain. In order to deal with these dumped scraps, the government has dispatched a lot of manpower and ma...

[0002] At present, in the deep processing of mineral mining in our country, such as the deep processing of stone, there are many corner wastes in the production process of enterprises. Since these corner wastes can no longer be reused in the production process of enterprises, in order to reduce the cost of daily waste treatment, enterprises often use These corner wastes are dumped on roadsides, fields, slopes, rivers, etc., and even piled on farmland, causing land and forest land to be occupied.

And with the effect of wind and rain, these scraps often cause pollution to the surrounding environment.

In order to deal with these dumped scraps, the government has dispatched a lot of manpower and material resources to transport and bury them, but companies often dump them secretly, repeatedly prohibiting them, which makes it a headache for the government to deal with
