Horizontal novel centrifugal concentrator

Abstract

A horizontal novel centrifugal concentrator comprises a frame (8), an outer cover (1), a rotating drum (2), a variable frequency reducing motor (4) connected with the rotating shaft of the rotating drum through a coupler (3), a flushing system (5) arranged in the outer cover and connected with an external water supply system, an ore distributor system (6) below the outer cover, an ore receiving bucket (7) below the outer cover, a feeding system (9) arranged outside the outer cover and communicated with the rotating drum, wherein the rotating drum comprises the rotating shaft, a horn-shaped rotating disc and a circular truncated cone-shaped rotary drum; the rotating shaft is sleeved with the rotating disc; the rotating disc is sleeved with the rotary drum; the large end surface of the rotary drum is connected with the outer edge of the rotating disc; the tilt angle of the opening in the internal face of the rotary drum is 2-6 degrees; the flushing system comprises a water inlet pipe with a pneumatic ball valve and flushing nozzles in the rotary drum; the ore distributor system comprises a cylinder, an oscillating shaft, a connecting arm and an ore distribution hopper; one end of the connecting arm is connected with the push rod of the cylinder and the other end of the connecting arm is connected with the oscillating shaft; a lifting arm at the top of the ore distribution hopper is connected with the oscillating shaft; the feeding system comprises an ore distribution box and at least two feeding nozzles; a pneumatic knife gate valve is arranged at the ore inlet of the ore distribution box; the feeding nozzles are mounted at the tail ends of feeding pipes of the ore distribution box and face to the internal face of the rotary drum. The horizontal type novel centrifugal concentrator has a simple structure and a good concentration effect, and is easy to control and maintain.

Description

technical field [0001] The invention relates to the technical field of metal gravity beneficiation equipment, in particular to a centrifugal beneficiation machine for nonferrous metals, ferrous metals and precious metals. Background technique [0002] At present, the domestic mineral processing industry widely uses shaking tables and centrifugal concentrators as gravity beneficiation equipment for metal ores. The shaking table has the disadvantages of large space occupation, low production efficiency, high maintenance cost, and high labor intensity of workers. Moreover, the wooden materials used to manufacture the shaking table are strictly controlled and difficult to purchase. Therefore, new equipment is used to replace the shaking table equipment It is the development trend of gravity beneficiation process. The traditional centrifugal concentrator also has many deficiencies. The first is that the transmission mode is motor-belt pulley transmission. Due to the inertia of ...
