The vacuum filter and large water pump (before start-up) of the concentrator need to use the vacuum pump to extract the air.
A vacuum pump is a compressor that sucks out gas from thin air spaces and exhausts it to the atmosphere. Generally, the pressure of the gas it sucks is lower than the atmospheric pressure (recently manufactured vacuum pumps can make the residual pressure in the container as large as 1 × 10-15 mm silver column), and the pressure of the exhaust gas is slightly higher than atmospheric pressure.
Vacuum pumps are also distinguished by reciprocating and rotating types, and their working principles are the same as those described above. There are two types of vacuum pumps used in ore dressing plants: wet and dry.
Dry-type vacuum pumps only suck air from a certain space (such as air in a filter), which can evacuate 98%; while wet-type vacuum pumps suck out liquid and air together and can only evacuate 85%.
In order to maintain a certain volume of the water ring and remove heat, water must be continuously circulated. In order to supply water to the vacuum pump, a special water tank is connected to the discharge pipe, and a gate valve on the tank is used to adjust the circulating water volume. The used water is placed in the box with the air. In order to avoid blade end surface abrasion, there should be no inclusions in the circulating water, otherwise the blade will be abraded, and the air extraction volume will decrease as the wear increases; the general wear should not be greater than 0.1 mm.
