Since the gypsum grinding mill is not completely closed and sealed, when the stone is squeezed and impacted, the air in the gap of the stone powder is squeezed and moved outward at a high speed, which drives the dust to escape together and instantly raises a large amount of dust. The dust-laden airflow is discharged downward (small part) through the chute or upward (mostly) through the feed port to produce a high concentration of dust around the feed port.

Being in this state for a long time will not only cause serious pollution to the environment, but also cause great harm to the human body. Then how to control the dust pollution of the crusher, as a professional gypsum mill manufacturer, what aspects should we make improvement measures?
Below, Collierk will introduce some dust control methods for gypsum mills.

(1) Sealing control Seal the dust source with a sealing cover to minimize the spread of dust.

(2) Eliminating the high potential energy difference of the hopper, protective cover, chute, etc. of the moving equipment, which is the main cause of the dust overflow, which should reduce the drop and reduce the inclination of the chute. The closed chamber is good for negative pressure, which is beneficial to the collection of dust in the production of gypsum mill.

(3) Gypsum mill wet dust removal and exhaust dust removal According to the cause of dust generation, countermeasures for controlling the dust source can be separately formulated: spray device is installed at the feeding port and the tape transfer point, and the amount of water to be humidified is controlled. The earth reduces the dust pollution at the transfer point in the crushing workshop; when the transfer point is especially poor in the ventilation of the underground building, the centrifugal fan should be used to force the ventilation to enhance the dust speed and air volume; when the tape runs to generate dust, the bag filter is used. Negative pressure exhaust control dust source.
