Selection of Mining Slurry Pump

About 80% of the application of slurry pumps in the mining industry are used in concentrators. Slurry pumps are mainly used to transport slurry in the beneficiation process. It plays the role of conveying, feeding, pressurizing, and discharging. Slurry pumps can not only be used in conjunction with magnetic separators, flotation machines, and screening and grading equipment, but also directly transport the slurry to designated locations through pipelines. Generally, the ore pulp conveyed is concentrate and tailings.

1. Selection of mining slurry pump

A. Clarify the basic parameters of working conditions, such as flow rate, head, slurry specific gravity, PH particle status, etc.

B. Determine the series model of the slurry pump. Then read the performance curve through the flow rate and head to determine the specific model and size of the pump.

C. Through the shaft power, the motor power that is nearest and greater than the shaft power is the final motor power.

2. Requirements for use with supporting equipment

For example, in the flotation process, the problem of foam treatment. Whether to consider the foam coefficient, and whether to take measures to eliminate foam. When used in conjunction with a cyclone during the screening process, it is necessary to provide pressure to the cyclone alone.

3. Other special working conditions

The weight concentration generally mainly considers the degree of abrasiveness of the slurry. The higher the slurry concentration, the higher the abrasiveness and the higher the slurry-specific gravity. So there are heavy-duty, neutral, and light-duty slurry pumps. It is divided according to the content of the slurry, and there is no strict limit.

The Ph value is one of the material factors for judging and selecting the flow-passing parts of the pump (generally, the ph value of 5-12 is to consider the range of metal flow-passing parts, and rubber or other special materials are considered for the rest of the range. be flexible).
