Sand and gravel powder separation equipment and method for separating sand and gravel powder using the separation equipment

Abstract

The invention relates to sand and gravel powder separation equipment, including a shell, which is provided with an air inlet area, a breaking area, a powder removal area, a diversion area, and an air outlet area that are connected in sequence. A material outlet is provided, the air inlet position of the air inlet area is set as the air inlet, and the air outlet position of the air outlet area is set as the air outlet. The fan blade device and the fan blade adjustment device are installed in the area, and several deflector plates are arranged in the diversion area, and the sand and gravel powder mixture in the feed inlet is broken up by the cascade breaking device, and the broken sand and gravel It flows out from the discharge port, and the broken stone powder is carried by the wind at the air inlet in turn through the fan blade device and the deflector, and finally flows out from the air outlet; the invention also provides a kind of separation equipment for sand and stone powder method. The invention not only has high sand and gravel powder separation efficiency and good effect, but also has a high degree of automation.

Description

technical field [0001] The invention relates to the field of machine-made sand production, in particular to sand and gravel powder separation equipment and a method for separating sand and gravel powder by using the separation equipment. Background technique [0002] Dry sand making has the advantages of good gradation, low production cost, no restrictions on water sources and the environment, and is more environmentally friendly. At present, most of the machine-made sand produced by ore is produced by dry sand making. In the process of machine-made sand production, the ore needs to be crushed , Stone powder separation, screening, super particle size re-crushing and a series of operations. In the process of crushing ore into sand, about 10-20% of stone powder will be produced. Stone powder is mixed with gravel and sand. On the one hand, the mixture is easy to generate dust during transportation, causing environmental pollution. On the other hand , if the stone powder enters...

Problems solved by technology

In the process of crushing ore into sand, about 10-20% of stone powder will be produced. Stone powder is mixed with gravel and sand. On the one hand, the mixture is easy to generate dust during transportation, causing environmental pollution. On the other hand , if the stone powder enters the vibrating screen for screening, it will lead to a decrease in processing capacity and screening efficiency
