Embodiment 2

[0045] This embodiment relates to a process for recycling granite waste rock powder, comprising the following steps:

[0046] (1) Disintegration: Granite waste rock powder is sent to the double-shaft disintegrator by a forklift, and the massive granite waste rock powder is initially broken up, and the disintegrated granite waste rock powder is granular.

[0047] (2) Drying: After the granular granite waste rock powder is discharged from the discharge port of the double-shaft crusher, it enters the straight dryer through an inclined conveyor belt for drying; the heat source of the straight dryer passes through the biomass burning furnace. It is provided that the flame of the biomass combustion furnace is in direct contact with the granite waste rock powder, and before the granite waste rock powder is discharged from the straight cylinder dryer, the dust and combustion substances in the granite waste rock powder are removed by a negative pressure powder modification device.

Abstract

The invention relates to a production line and a process for recycling waste granite powder. The production line comprises a double-shaft beater, a straight-cylinder drying machine, a composite crusher, a vibrating screen, a plurality of storage silos and a stirring and packaging machine. A discharge outlet of the double-shaft beater is connected with a feed inlet of the straight-cylinder drying machine through a conveying belt. The composite crusher is arranged below a discharge outlet of the straight-cylinder drying machine. A discharge outlet of the composite crusher is connected with the vibrating screen through a lifter. The vibrating screen is connected with the storage silos through a wind pressure transfer device. The storage silos are connected with the stirring and packaging machine through a spiral conveyor. The process includes beating, drying, crushing, screening, mixing and packaging. The production line and the process provided by the invention have the advantages that the problems of environmental pollution caused by discharge of the substantial waste granite powder can be solved, powdery building materials can be produced, and production cost is reduced at the sametime.

Description

technical field [0001] The invention belongs to the technical field of recycling waste rock powder, and in particular relates to a production line for recycling granite waste rock powder and a process thereof. Background technique [0002] Granite is a natural stone composed mainly of quartz and feldspar. In recent years, the national natural granite mining volume has shown a rapid increase year by year. The output of granite in 2013-2015 reached 465 million cubic meters, 590 million cubic meters and 672 million cubic meters respectively. At the same time, the mining and processing process produced Hundreds of millions of tons of stone waste. [0003] In order to reduce production costs, traditional stone processing enterprises will discharge granite waste rock powder to landfill after simple treatment such as sedimentation. But over time, landfills can pollute the nearby environment. The random dumping of waste granite powder not only engulfed a large number of fertile f...
