Beneficiation shaker is a common equipment for separating fine ore
It is usually composed of bed surface, frame and transmission mechanism
In addition, there are flushing tank, ore feeding tank, machine base, etc
the whole bed surface is supported or lifted by the rack, and the rack is equipped with slope adjustment device

 
The beneficiation shaker can make the ore particles move in different directions according to their density and particle size, and fan out along the diagonal from the ore feeding tank, and discharge them along the edge of the bed in turn
The ore discharge line is very long, which can accurately produce a variety of products with different quality, such as concentrate, secondary concentrate, medium concentrate and tailings
As a gravity separation equipment, beneficiation shaker has been widely used for the separation of placer gold and other minerals, mainly for gold or coal preparation

 
The ore particles are subjected to the following three mutually perpendicular forces on the shaking table surface:
(1) Gravity of ore particles in medium;
(2) Hydrodynamic action of transverse flow and pulp flow;
(3) The power of differential reciprocating motion of bed surface

 
Under the action of these forces, the ore particle groups located in the bed strip ditch carry out two basic sorting movements: loose stratification and transportation zoning
The type of bed strip, bed surface friction and bed inclination have an important influence on the sorting process

1、 Loose stratification of particle groups on the bed surface
 
The transverse water flow flows across the bed strips and stirs up vortices between the bed strips
The upper ore particles in the strip ditch are loose under the action of pulsating water flow
The fine particles are suspended, while the slightly coarse particles are constantly rolling, transferring the heavy mineral particles to the lower layer
The ore particles in the lower layer are less affected by hydrodynamic force
In the longitudinal shaking movement of the bed surface, the shear velocity difference appears between the particles, and the particles squeeze and overturn each other, which increases the particle gap and makes the bed expand and loose
The local pressure of heavy mineral particles is large, and the light mineral particles enter the lower layer
In this transfer process, the mechanical resistance of the lower particles is encountered
Those particles with smaller particle size pass through the coarse particles and enter the lower part of the same density layer to realize separation and stratification

 
The result of stratification is that fine-grained heavy minerals are in the lowest layer, coarse-grained heavy minerals are in the upper part, and some fine-grained light minerals are mixed, and then coarse-grained light minerals are in the upper part
Fine ore particles are suspended in the upper layer and washed away by transverse water flow

 
2、 Transportation and zoning of ore particle groups on the bed surface
 
While the particle group is loosely stratified in the ditch, it is also subject to the flushing action of transverse water flow and the thrust action of longitudinal differential shaking of bed surface
The transverse velocity of fine particles suspended in the water flow is the smallest
As the particles move to the concentrate end, the bed height decreases, and the layered ore particles located in the bed ditch are stripped out in turn
The lateral velocity of coarse-grained light minerals is large, followed by fine-grained light minerals and coarse-grained heavy minerals, while the fine-grained heavy minerals can maintain a minimum longitudinal distance to the concentrate end

 
Main types
 
According to the bed configuration, there are left type and right type
Stand at the head of the bed and look at the bed surface
If the ore feeding trough is on the left, it is the left shaking table, and on the right, it is the right shaking table;
According to the installation mode, it can be divided into seat type and suspension type;
According to the number of bed layers, there are single-layer shaking table and multi-layer shaking table;
According to different raw materials, there are shaking tables for beneficiation and coal preparation;
According to the particle size of the treated ore, there are sand (2 ~ 0
2 mm) shaker and slime (~ 0
2 mm) shaker
Ore shaker can be further divided into coarse sand (2 ~ 0
5mm) shaker and fine sand (0
5 ~ 0
2 mm) shaker

The bed surface is the working surface of sorting
There are trapezoidal and rhombic shapes
Trapezoidal bed surface is almost adopted in China, which has the advantage of easy configuration
The triangular ore free zone on the trapezoidal bed surface is cut off and connected to the lower tailings side to form a rhombic bed surface, which can effectively use the sorting surface and prolong the sorting time
Coal preparation shakers are widely used in foreign countries
