Function for Several Components of Shale Shaker for Drilling Mud System

Shale shaker is mainly using the vibration motor excitation to cheer for the vibration source, and make the mud fluid being thrown up on screen and it do the forward a straight line at the same time. The material into the sieving machine from the feeder evenly eeding port, and though all kinds of specifications by multilayer sieve, and sieved up and under respectively from their respective outlet. Linear shale shaker (linear sieve) with many advantages such as, stable and reliable, low consumption, low noise, long service life, stable vibration mode, high screening efficiency, etc. It is a new type efficient shaker equipment, and it widely used in mining, coal, smelting, building material, refractory material, light industry, chemical industry, etc.

Shale shaker is mainly composed of shale shakers screen box, vibrator, hanging (or supporting) device and motor, etc. Electric shaker machine drive vibrator of spindle by the v-belt, due to the vibrator unbalance weight on the centrifugal force effect, make the vibrating screen box, thus to change the vibrator eccentric, can get the different amplitudes be obtained.

Feeder of Drilling Mud Linear Motion Shale Shaker
The mud returned from the well or cuttings to be treated will flow into the drilling shale shakers via the feeder. The feeders can be categorized into weir type, box type and bucket type. The weir type and box type feeders are mainly used to buffer the flow rate of drilling fluid and evenly distribute the fluid onto the screen to reduce the impact of drilling fluid on the screen, extend the service life of screen and improve the treatment effect. Besides, the weir type feeder can also short-circuit the machine if necessary. The bucket type feeder is mainly used with the dryer shaker to collect and distribute cuttings.

Locking Device
It adopts a self-locking structure, possesses a reliable performance and can be easily operated. It only takes 30 seconds to lock or unlock the screen box. On the market, most shale shakers are fastened by bolts, the operation consumes more time and labor, and fasteners are easily lost.

AWD Angle Adjustment System
The patented lifting system allows for easy and quick operation, and simple maintenance. Compared with the usual lifting device of hydraulic cylinder, AWD deck angle adjustment system enables one person to steplessly raise or lower the screen basket from -1℃ to +5℃ without interrupting operation only by turning the handle, which is convenient and efficient. The angles at left and right sides of screen basket are synchronously adjusted, which is more convenient and stable, and can avoid the common mud deviation. The rolling pulley structure is more labor-saving than the sliding type.

Separation Principle of Drilling Fluids Decanter Centrifuge

The mud separation process between solid phase and liquid phase is completed in the roller. Decanter centrifuge separation principle is to use high-speed rotating roller driven into the mud in the high speed rotating drum, mud was dumped into the wall to form a liquid circle, solid phased particles of liquid ring get greater than its own gravity for undreds or even thousands of times the effect of centrifugal force, will overcome the resistance of the slurry viscosity to the roller on the inner wall of rapid subsidence formed solid layer, liquid forming liquid layer.

The desander centrifugal force by solid phase particles of liquid ring and the ratio of its own gravity called decanter centrifuge separation factors, the larger desander centrifuge separation factor can separat finer particles from the mud. Currently drilling desander centrifuge can be divided into three types according to the size of the separation factors:

a.Low speed decanter centrifuge：it also called "Barite Recovery of Decanter Centrifuge", the separation factors is 500 ~ 700,for low density of solid phase, the separation point is 6 ~ 10μm.For high density solid phase, the separation point for 4~ 7 μm, the decanter centrifuge is mainly used for recycling barite.

b.Medium-speed decanter centrifuge: the separation factor of about 800, 5 ~ 7 μm, used to remove harmful solid phase of mud, control mud weight and viscosity, this is the drilling crew most used centrifuge resently.

c.High-speed decanter centrifuge: its separation factor is about 1200 ~ 2100, the separation point is 2 ~ 5 μ m, used to remove the harmful solid phase, control the mud viscosity, high-speed centrifuge discharge tank, liquid back into the circulatory system, at present our company in Mongolia drilling crew have high-speed centrifuge.
