GNZS703 shale shaker produced by GN solids control has been widely used in oil & gas drilling. GNZS853 shale shaker is normally used for drilling cuttings treatment.
Below is the photo taken in South America oilfield drilling site. They use GN shale shaker to separate the large solids from the drilling fluids and get clean mud for reuse. Also they user GN shale shaker as a underflow shaker to help the performance of desander cone & desilter cone.

To know how to operate GN shale shaker is much more important, also the maintenance. Only if you operate and maintain it according to the manual, you will use it same with Derrick, SWACO shale shakers.
1 Angle adjustment
The angle can be adjusted both under running and off condition.When delivered ,the deck is horizontal(0°) 。While operating with the same shaker screen, according to the worksite mud property, and feeding capacity ,by adjusting the deck angle in order to improve the treatment result .When the drilling mud run off, enlarge the deck angle to solve the problem. Angle adjustment range -1°~+5°，rated angle 0°~3°。
2 Pool configuration
A better pool configuration can maximize the screen area and such achieve better result. It is hard to set the deck angle at one time ,it needs the operation personnel adjusting several times according to the flow of the mud .The best pool configuration is when the mud covers the first and second shaker screen.

GN solids control developed a new product- mini shale shaker, model GNZS752. It can meet the requirement for the clients who do not need so large treating capacity, but want to find an economic way to separate big solids from the drilling fluids.
mini shale shaker
GNZS752 shale shaker with unit treating capacity 264gpm, 2 screen panels with total screen area 1.35m2, G-force 6.3G adjustable, total power of this shaker is only 1.0KW, and total weight 800 kgs. Based on these parameters, we called it mini shale shaker.
This linear motion shale shaker GNZS752 can be widely used in HDD, water well drilling , shadow drilling and other drillings which need small treating capacity. After the new mini shaker is developed, there are many clients showed their interests. Before they have to use bigger shaker 2-panel GNZS852 or even 3-panel GNZS703. These shakers can treat the drilling mud better because of their large treating capacity, but it is a waste of money.
Comparison between GNZS752 and Brandt mini Cobra 2-panel shaker
Motor power: Brandt mini Cobra is 1.1KW x 2 , GN mini shaker is 0.5KW x 2
Screen area: Brandt mini Cobra is 1.6m2, GN mini shaker is 1.35m2
Screen panel: Both of them are 2 panel
Screen type: pretension, repairable

Vibrating screen normally called shale shaker in oil and gas drilling industry. GN solids control produce vibrating screen machine and replacement screens for it.
GN vibrating screen
By the motor force and adjusting the amplitude of the eccentric shaft, vibrating screen moves quickly like a circle. Materials in the sieve case can be saperated and screened from the sieve pore in this process.

GN solids control choose Italy Oli brand vibrating motor for all our shale shakers. Vibration motor is important components for shale shaker, I will introduce briefly about vibrating motor installation & maintenance.
1 How to install vibrating motor ?
shale shaker vibrator
(1). Before installing vibrator, turn off and lock out/tag out all energy sources to mounting structure according to ANSI standards。
(2). If using a cutting torch or welding, test atmosphere for gas level or dust content.
(3). Make sure mounting surface is strong and flat, 0.25 mm acros vibrator feet. (This will minimize internal stress to vibrator casting when tightening mount bolts.
(4) Make sure mounting surface and vibrator are clean and free of debris, paint, and oxidation.
(5) Before installing vibrator onto mount, apply thread sealing compound to all bolts.
(6) After the vibrator has been operated for 10 to 20 minutes, check bolt torque. Tighten if necessary
2 How to maintain vibrating motor?
(1)Clean dust on shell regularly
(2)Before operating, must check the bolts to confirm whether there is loose or not. Otherwise, we must screw bolts tight before running shaker
(3) Inspect the cable, whether there is wear, hold down, crushing, etc.
(4) the vibration motor should be under good lubrication during operation:
Motors before fixed on shaker, the bearing is filled with SKF specific lubricate grease, the temperature range is -40 ~ 200℃
During running, every 2000 working hours user should makeup LGHP2 lubricate grease once. Every bearing can not be filled over 25.8g.

GNZS703 shale shaker is widely used for oil and gas drilling and directional drilling in the world.
1 shaker deck adjustment
A spring-loaded plunger and reversible pawl provide a ratcheting action during movement of the operating handle. A full 180 degrees of movement is possible in both directions. Depending on pawl setting, moving the handle in one direction turns the jack screw to raise or lower the screen frame, while in the other direction the jack screw remains stationary during handle movement. The spring-loaded pawl permits the operator to switch the direction to either raise or lower the screen frame, as required.The angle of the discharge end of the screen frame is infinitely adjustable within the equipment’s available range.
(1)Inspect discharge duct connection on side of hopper for leaks. Tighten connection and/or add silicone sealant to prevent leakage.
(2)Inspect cover on unused hopper discharge connection for leaks. Tighten connection and/or add silicone sealant to prevent leakage.
(3)Using a water hose, wash off accumulated process material from screen frame, interior of hopper and AWD angle adjustment components.
(4)Excess process material in these areas may impede angle adjustment of screen frame and can reduce screen frame vibration if the frame bottoms out on the buildup.
(5)Check for and remove any accumulation of process material or other obstruction in feeder interior. Feeder blockage may cause excessive splashing and uneven distribution of slurry onto the screen bed.

GN designed a new patent linear motion shale shaker, GNZS70-3B. It is designed to replace the previous model GNZS70-3 shale shaker, which is found not so economic and practical before.
Specification of GNZS70-3B shale shaker
1 Vibrating mode: Linear motion
2 Single deck shaker with 3 screen panels
3 Quick lock( wedge technology operation), which enables screen panel replacement in less than one minute. In drilling site operation, time is more important than money, so easy operation of screen replacement is necessary. It enables for an easy ratchet-type installation of the wedges, which eliminates hammer damage to the screens, as well as the paint on the sidewall of the shaker basket. You do not need any tensioning bolts or system, which can provide a small parts inventory, thus enabling cost savings to be realized.

How to use a vibrator of shale shaker, it contains two keys: disassembly of the bibrator of shale shaker, reassembly of shale shaker. And you need exactly remmber that disconnect power to the electric motor and lock the disconnect swithch in the open position.
Disassembly of the Vibrator of Shale Shaker
WARNING: Disconnect power to the electric motor and lock the disconnect swithch in the open position.
Shale Shaker Motor
1. Remove motor and drive pulley guard.
2. Remove the counterweight guard from both ends of the vibrator shaft.
3. Loosen the four motor support bolts located under the motor, loosen the V-belts and remove them.
4. Remove the V-belt sheave , by first loosening its taper lock hub.
5. Remove the counterweights , by removing the clamp screws and reusing the screw to open the slots in the counterweights, by tightening the screws into the tapped holes.
6. Remove the collars and the retainers with the Spiro lox rings in their grooves. Remove cartridge cap screws.
7. Remove retaining ring from the drive side only. By striking on one end of the shaft with a lead hammer or a hammer and a block of hardwood, it is possible to start to drive out the cartridge on the other side.
8. Then it should be easy to pry either or both cartridges loose from their bores in the housing ends. If difficulty is experienced a cartridge can be bumped from the inside by striking the shaft again at the other end. When one cartridge is removed the shaft can be slipped from the housing.
