device

Small shaker is one of the main equipment for small channel steel shaker beneficiation, widely used for separating rare and precious metals such as tungsten, tin, tantalum, niobium, gold, etc. Small shaking table equipment can perform rough selection, selection, and scanning, selecting different particle sizes such as coarse sand (2-0.5mm), fine sand (0.5-0.074mm), and mineral mud (-0.074mm). It can also be used to select iron, manganese ore, and coal. When processing tungsten, tin, and other ores, small shaking table equipment can effectively recover particles with a size of 2-0.22 millimeters.

The utility model of small shaking table equipment has 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 small shaking table equipment is mainly composed of eight parts, including bed head, motor, slope adjusting device, bed surface, ore trough, water tank, incoming and rewinding bars and hoisting 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 small rocking 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.

Its shape is a right angled trapezoid, and within the wooden frame, the wooden boards are assembled into a plane along an oblique direction (intersecting 45 degrees with the axis). The bed surface is divided into two types: painted gray carved bed surface and rubber bed surface. Choose fine mud for the paint gray groove bed surface, and choose coarse ore for the rubber bed surface. The bed surface for selecting fine sand has a downward inclination of about 0.5 degrees along the longitudinal direction, while the small desktop shaker used for selecting coarse sand has a vertical inclination of 1-2 degrees and is lifted at the concentrate end. Adjust the size of the longitudinal slope through bolts.

Use 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 support of the small desktop rocking table 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.
