Fiberglass Concentration Shaking Table for Gold Mining 

Introduction 

concentration table is our key products; we get 30 years production history. It’s also been called shaker table, 6-s shaking table, concentration table, gold shaking table, gold separating table, gold refining table, concentration table  concentrator. The concentration table is widely used in gold concentrating , tungsten & wolfram concentrating, coltan & columbite separating, tin & cassiterite processing, chrome, zircon, garnet, ilmenite, monazite separating, which gets a high concentration ratio and high recovery rate. And we have special designed different kinds of shaking tables, such as gold shaking table, tungsten shaking table, wolfram shaker table, concentration table for coltan, tin shaking table, cassiterite shaker table, concentration table for zircon, concentration table for columbite. There are two series: one is 6-S concentration table which is used for industrial use, and the other is LY series shaking table, which is used for laboratory test or small scare mining. All of our shaking tables complies of CE and GB standard. The concentration table consisted of table deck, feeding chute, gear box, electric motor and frame. The deck is made by fiber glass reinforce plastic, while the feeding chute is normally made by wood. Our JXSC brand concentration table get a well-know reputation of high quality, easy installation, and good performance. With 30 years of manufacturing experience, we know how to provide a concentration table  to meet our customer’s special requirement. And we insist in providing high end products instead of lower the quality to penetrate the market. Regarding the installation and commissioning of shaking table, first of all, the basement should be leveled and steady, to prevent the moving of the frame. Before operating, the angle of the deck should be adjusted about 3-5°, feeding chute side up; and the gear box should lubricated with engine oil, and check if the oil pump is working; the supporting plate for the deck should be at the centre position. For the concentration table

operating, feeding amount and water adding amount should be adjusted and set according to the separating effect, and then set the collecting funnel.

concentration table application

Lab concentration table is one of the commonly used equipment to conduct gravity concentration for feasibility study and test of ores for labs. and small beneficiation plant. It is applicable for separations of fine-grained and micro-grained rare metal, ferrous and non-ferrous metal, precious metal , coal and other minerals. It can carry out ore concentration operation independently and also can operate in conjunction with jig, screw separator, centrifugal separator and other equipment. With smooth deck surface, wear resistance, and no deformation. The ore sand tables and ore slime tables can be chosen freely. Also the feed method can be chosen left side or right side. It’s very convenient for site installation.

Laboratory concentration table is to make separations based on the difference of specific gravity of feed materials, reciprocating asymmetrical movement and the stratification performance of the inclined table surface in the lateral water flow with obvious zone of the minerals with different specific gravities on the table, high quality of concentrates produced, convenient operation and adjustment and other features.

The table surface is constructed of ore sand or slime and is made up of glass fibre reinforced plastic or aluminum alloy.

structure and working principle

This machine mainly consists of table box, table surface, and table frame.

1. The table box is hyperbolic link mechanism. When the eccentric shaft rotates, it drives the upward and downward movement of the connecting rod. When the connecting rod moves downward, the toggle plate expands. The toggle plate on the right is supported on the supporting seat fixed with the draw bar while the toggle plate on the left is supported on the adjustable supporting seat (this seat can only move upward and downward), which is installed together with the supporting seat through special bolts. One end of spring is covered on the supporting seat and the other end is covered on the adjusting stud disk above the fixed sleeve.

The belt pulley passing the motor is driven to rotate. It drives the connecting rod and pushes downward the toggle plate to press the spring, as well as pushes the draw bar to carry the table surface forward. When the connecting rod moves upward, it drives the table surface to move backward under the action of spring tension. By doing it, the motion becomes continuous. The rotary motion becomes longitudinal straight reciprocating motion.

The stroke is obtained through the twisting of special stud. The whole mechanism is put in the shell of table box.

2. The working part of concentration table is a table surface made of aluminum alloy. Its appearance is an irregular quadrangle.

Paint the outside of table surface with ash and spray black lacquer for 3 to 4 times. The original rifle bar can be replaced with dadoing. The dadoing is arranged in parallel with the shaking direction of table surface. The dadoing near the feeding end on the table surface is short. It become gradually long as the lower part of it becomes. Their finishing points are arranged on the diagonal 50mm away from the discharging end of table surface.

There is feeding box along the end of the table surface and next to the corner at the one side of the table box. A water tank is parallel to the feeding box. Both of them are made of organic glass and are used to add flushing water. The flushing water flows to the table surface through rotatable rhombus rubber brake block fixed at the bottom of tank, and change the position of the angle of the rhombus rubber brake block. The water flow and its direction can be adjusted. Such feeding box is installed in the right corner of the table surface, hence called right feeding box.

3. The bed surface is installed on the two cast iron beams. The beams are fixed on the sliding bearings and the bearings are fixed on the angle iron frame.

There is inclination angle for the table surface horizontally which can be from 0° to 10°. Adjust the horizontal sliding bearing and hand wheel in the middle. At the one end of the hand wheel shaft which match the nut with arc groove. Such nut matches the connecting rod fixed on the draw bar. When the hand wheel turns to the direction of nut, it drives the rotation of connecting rod, draw bar, and table surface.
