Production line and production method for preparing mine filling cementing materials from lead-zinc slag

Abstract

The invention discloses a production line and production method for preparing mine filling cementing materials from lead-zinc slag. The production line comprises a crusher, a primary conveying belt, adryer, a secondary conveying belt, a crushed material lifter, a crushed material slideway, a buffer bin, a tertiary conveying belt, a pulverizer, a powder lifter, a powder concentrator, a quartus conveying belt, a backflow conveying belt, a fine powder lifter and a dry mixing device. Crushed materials discharged from a discharge port at the top of the crushed material lifter enter the buffer binthrough the crushed material slideway; the crushed materials discharged from the buffer bin are conveyed into a feed hopper of the pulverizer through the tertiary conveying belt, and the powder discharged from a discharge hopper of the pulverizer is conveyed into the powder concentrator through the powder lifter. According to the production line, continuous and large-scale operation is realized, the production efficiency is improved, and the powder granularity requirement of main materials is guaranteed. According to the production process, the lead-zinc slag is taken as the main materials, sothat the garbage generated in lead-zinc ore operation is fully utilized, the problem of garbage treatment is solved, and the garbage is turned into wealth.

Description

technical field [0001] The invention relates to production equipment and technology for mine filling cementing material, in particular to a production line and production method for preparing mine filling cementing material from lead-zinc waste slag. Background technique [0002] my country is a big producer and consumer of mineral resources. There are more than 110,000 non-coal mines alone, with an annual output of nearly 5 billion tons of ore and an annual output value of more than 500 billion yuan. Mining is the basis for the development and utilization of mineral resources, but while mining provides raw materials for human beings, it will inevitably destroy the surface environment. With the rapid development of industry, the demand for minerals is increasing rapidly, but mineral resources are becoming increasingly exhausted. The safety and environmental problems caused by resource development and utilization are quite prominent. However, most mining enterprises in my cou...
