Energy-saving and environment-friendly iron-removing stone powder recycling, granulating and processing technology

Abstract

The invention discloses an energy-saving and environment-friendly iron-removing stone powder recycling, granulating and processing technology. The technology comprises the following steps: (1) collecting stone powder and removing iron from the stone powder; (2) conducting mixing: stirring stone powder and natural biogum into a mixture, and conducting extruding; (3) conducting drying: drying the mixture through a drying device; and (4) conducting granulating: conveying the dried mixture into a granulator, granulating the dried mixture through the granulator, and conducting storing. Iron in thestone powder can be removed and then recycled, the problem that the stone powder occupies a large area can be solved, the environment can be improved, and more energy is saved and more environment isprotected.

Description

technical field [0001] The invention relates to a stone powder granulation process, in particular to an energy-saving and environment-friendly recovery and granulation process for iron-removing stone powder. Background technique [0002] Stone is a building decoration material, which is widely used. The original mined stone is relatively large and irregular in shape. Before use, it needs to be cut into slabs, stones, etc. for convenience; and the surface of the stone is relatively rough, and it needs to be polished before it can be used; A large amount of stone powder will be produced during the stone cutting and grinding process. When the staff is working, the stone powder floats in the air, causing dust to fly and pollute the air. The poor working environment increases the probability of the staff's lung disease; and these existing The stone powder is directly discarded or transported to the landfill. During the transportation, the stone powder is easy to leak and fly, and...

[0002] Stone is a building decoration material, which is widely used. The original mined stone is relatively large and irregular in shape. Before use, it needs to be cut into slabs, stones, etc. for convenience; and the surface of the stone is relatively rough, and it needs to be polished before it can be used; A large amount of stone powder will be produced during the stone cutting and grinding process. When the staff is working, the stone powder floats in the air, causing dust to fly and pollute the air. The poor working environment increases the probability of the staff's lung disease; and these existing The stone powder is directly discarded or transported to the landfill. During the transportation, the stone powder is easy to leak and fly, and the stone powder is scattered along the road, which expands the scope of pollution; it not only takes up space, but also causes environmental dust pollution, destroys vegetation growth, and is not environmentally friendly. ; Moreover, during the cutting and grinding process, the tool will be worn, and the iron filings dropped by the tool will be mixed in the stone powder. The iron-containing stone powder cannot be recycled and reused due to the influence of iron, and the pollution is more serious
