The gravity separation shaker is one of the main equipment for gravity beneficiation, which is widely used for separating tungsten, tin, tantalum, niobium and other rare and precious metal ores. The heavy selection equipment shaker is suitable for rough selection, selection, scanning and other different workpieces, selecting different particle sizes such as coarse sand (2-0.5mm), fine sand (0.5-0.074mm), and mineral mud (-0.074mm). The Jiangxi gravity separation shaker can also be used for selecting iron, manganese, and coal mines. The fixed beneficiation shaker has an effective recovery particle size range of 2-0.22 millimeters when processing tungsten ore, tin ore, and other ores.
The beneficiation process of the Jiangxi Gravity Separation Shaker is carried out on an inclined bed surface with multiple strips. The ore particle group is fed from the feeding trough at the corner of the bed surface, and the lateral flushing water is supplied by the feeding trough. In this way, the ore particles are stratified according to their specific gravity and particle size under the action of gravity, lateral water flow impulse, and the inertia and friction force of reciprocating asymmetric motion of the bed surface, and move longitudinally and laterally along the inclined bed surface. Therefore, ore particles with different specific gravity and particle size flow in a fan-shaped manner from A to B along their respective motion directions, discharged from different areas at the end of the concentrate and on the tailings side, and finally divided into concentrate, intermediate ore, and tailings.
The Mohs scale hardness of the metal used in the shaker of Jiangxi gravity concentration is 9, which is much lower than the Mohs scale hardness of the diamond 10.
Jiangxi Gravity Separation Equipment Shaker Fixed Shaker has a high ore enrichment ratio, high sorting efficiency, easy supervision, and convenient adjustment of travel. After changing the lateral slope and stroke, the bed surface can still maintain balance, and the spring is placed inside the box, with a stable structure, and the final concentrate and tailings can be obtained in sequence.
The shaker of Jiangxi gravity concentration equipment is mainly composed of eight parts, namely, bed head, motor, slope adjuster, bed surface, ore trough, water tank, incoming strip, hook and hook system.
Adopting a crank connecting rod transmission mechanism to achieve longitudinal reciprocating motion of the bed surface. During the up and down movement of the rocker, the motor is driven by a large pulley to rotate the crankshaft. During the up and down movement of the rocker, the elbow plate is used to push the rear shaft and reciprocating rod backwards, causing the spring to be compressed. The bed surface is connected by a connecting rod and a reciprocating rod, so it also moves backwards at this time. When the rocker rod moves upwards, the bed surface also moves forward due to the expansion and contraction effect of the spring.
When the bed surface moves forward, the angle between the elbow plates changes from large to small, and the horizontal movement speed of the elbow plates changes from small to large. The forward movement of the original bed surface is from slow to fast, and conversely, from fast to slow, there will be equal differential movement, which can ensure the forward movement of materials on the bed surface and sorting according to specific gravity.
The surface of the Jiangxi Heavy Selection rocking bed is a right angled trapezoidal shape, with stools arranged diagonally (at an angle of 45 degrees with the stools) in a wooden frame to form a flat surface. The shading can be divided into two types: painted gray grooved bed surface and rubber shading. The painted gray grooved bed surface is used for selecting fine mud, and the rubber bed surface is used for selecting coarse mud. The bed surface used for selecting fine mud slopes downwards at approximately 0.5 degrees along the longitudinal direction, while the shaking table used for selecting coarse mud slopes downwards at approximately 1-2 degrees along the longitudinal direction and rises at the concentrate end. The size of the longitudinal slope is adjusted by the slope on the supporting mechanism.
The shaking table of Jiangxi gravity separation equipment uses a swinging support bed surface on the slope adjustment mechanism. The vibration support causes the bed surface to move up and down in a vertical plane in a forward and backward arc. The rocking table support is fixed on the adjusting seat plate by channel steel. When the adjusting screw is used to adjust the seat plate on the saddle seat with a handwheel, the inclination angle of the bed surface can be adjusted.
