Description

Technical Field

[0001] The utility model provides a device for separating sundries in molybdenum concentrate pulp, belonging to the field of pulp filtration. Background Art

[0002] During the overhaul and production process of ore dressing equipment, some plastic and rubber products such as mineral water bottles, woven bags, detonating fuses, and insulating tapes, etc., which are light in weight, are left in the equipment and not cleaned in time. During the production process, such sundries float on the surface of the pulp and enter the concentrate dewatering process after several stages of separation operations. Since high-efficiency, small-pass-through particle size, and high-lift slurry pumps are mostly used for transporting the pulp in the concentrate dewatering operation, the impellers of the slurry pumps are mostly closed impellers. The closed impeller generally has a relatively narrow flow channel and is often blocked by sundries, affecting the working efficiency of the slurry pump.
