Description

Exciting sloping plate ore separator

Technical Field

The utility model discloses an excitation sloping plate concentrating machine, and belongs to the field of concentrating equipment.

Background

The common devices for sorting fine-grained ores are mainly concentrating tables and belt chutes. The concentrating table is generally composed of three parts, namely a table surface, a frame and a transmission mechanism. Besides, it also has water-flushing tank, ore-feeding tank and machine seat, etc., and the whole bed surface is supported or suspended by machine frame, and on the machine frame a slope-regulating device is mounted. The concentrating table can make ore particles move along different directions according to different densities and granularities, and the ore particles spread in a fan shape along a diagonal line from the ore feeding groove and are sequentially discharged along the edge of the bed surface, and the ore discharging line is very long, so that various products with different qualities, such as concentrate, secondary concentrate, medium concentrate, tailings and the like, can be accurately produced. The mineral processing shaking bed is used as gravity separation equipment, and is widely used for separating minerals such as placer gold and the like, and is mainly used for gold separation or coal separation and the like. The ore particles are acted by the following three mutually perpendicular forces on the table surface: the gravity of the ore particles in the medium; the hydrodynamic forces of the transverse water and slurry flows. The combined action of the three acting forces makes the dynamic of the differential reciprocating motion of the bed surface asymmetric. The ore particle group in the bed strip ditch is subjected to two basic sorting motions of loosening and layering and conveying and separating belt under the action of the forces. The type of the riffle, the bed surface friction and the inclination of the bed surface have a significant influence on the sorting process. The disadvantages are as follows: the treatment capacity is small, the movement speed of ore particles on the bed surface is small, the economy is not enough, the occupied area is large, and the application is limited when the ore particles are generally used for treating rare and precious minerals.

The belt chute is an effective device for sorting fine-grained ore. Sorting was performed on an inclined plane formed by an endless rubber belt. The belt moves upwards at a certain speed, ore pulp is fed from the middle part of the inclined plane, heavy ore particles in the water flow of the inclined plane gradually sink down and are conveyed by the belt, the ore particles with small specific gravity are washed down by the washing water of the fine selection section, and finally, the ore concentrate is discharged from the upper part. The ore particles which can not sink on the belt or can be washed down by water flow after sinking are discharged from the lower end to become tailings. Therefore, the sorting principle of the belt chute is similar to that of a common chute, and the sorting purpose is achieved by utilizing the movement difference of ore particles in the inclined plane water flow. However, there are also different places between them, mainly: 1. the surface of the belt chute is in motion, and the motion direction is opposite to the water flow direction, so that the property of the water flow on the surface of the belt chute is influenced, and the motion of ore particles is also influenced; 2. the belt can generate more or less vibration in the moving process, and some belt chutes are provided with devices specially promoting the belt to vibrate, so that the vibration can loosen and layer ore particle layers on the chutes, and a certain effect is played on sorting; 3. the heavy products of the belt chute can be continuously discharged, and the operation is continuous; 4. the belt chute is washed by washing water, so that the quality of the concentrate is improved. The belt chute is mainly used for processing fine materials which cannot be processed by the shaking table or have poor sorting effect, the ore-rich ratio of the belt chute is higher and can reach more than 8, and the recovery effect is not lower than that of a common chute. Under the condition that the treatment capacity of the cross-flow belt chute is 9 times higher than that of the slime shaking table (the unit treatment capacity is 8 times higher), the sorting index is still higher than that of the slime shaking table. When the enrichment ratio is lower, the recovery rates of the two devices are close to each other. When the enrichment ratio is increased (over 10), the recovery rate of the cross-flow belt chute is slightly reduced along with the increase of the enrichment ratio, the enrichment ratio is increased from 10 to 50, and the recovery rate is only reduced by 8%. The recovery rate of the slime shaking table is reduced dramatically along with the increase of the enrichment ratio, the enrichment ratio is increased from 10 to 20, and the recovery rate is reduced greatly. It can be used for roughing, scavenging and concentrating. In the current equipment for treating fine materials, the effective concentration equipment is quite lacking, and the belt chute can be used for concentration and has better separation effect, which should be paid sufficient attention. The biggest defects of the belt chute are low unit productivity and large floor area, which prevent the belt chute from being popularized and used in roughing and scavenging.
