Check if the shale shaker screen, auxiliary motor, mud filling pump are all correct( they all must rotate in the direction the arrow shows, otherwise no sand can be discharged), Rules of operation: start-up,Switch on the mains first,Start-up the auxiliary motor and see if the motor run well . Start the main motor after the auxiliary motor run in normal for 30 seconds. Start-up the main shaker screen . Pay attention to the running condition of the centrifuge, if any abnormality occurs, stop it promptly, and find out the causes.Open the shunt valve of mud filling pipes, start-up the motor of mud filling pump, supply mud. Pay attention to sand discharging condition of the centrifuge. If no abnormality, regulate the fraction of flowing stream, increase the amount of feeding mud gradually. Split-flow should be done to lighten the load of the centrifuge when discharged sand is too much. Stoppage,Turn off the motor of mud filling pump, stop feeding mud to the centrifuge. Close the 2″ball valve in feeding pipe; open the flushing valves in feeding pipe and box body, flush for at least 10 minutes,Cut off the water supplying valve. Press the button “stop” on the main motor. Press button “stop” on auxiliary motor and cut off the mains after the drum stop rotating completely (Attention: Don’t cut off the mains while the drum rotate in high-speed. It may lead to auxiliary motor’s being damaged because drum may drive auxiliary motor to rotate in over-speed if the mains is cut off at the moment!!if you want to know this,pls click it to know)

The shale shaker will vibrate as elliptical, part of spare parts are interchangeable with international shale shaker (2) Adopts advanced vibration motor, reliable operation, run long time without any problem (3) The shaker screen can be flat type or pyramid type. Shaker deck can fix 3 pieces screen and make screens as different combination. This will lead screen take longest usable life. According to different drilling mud the screen mesh will be 40-200 mesh (4) Screen is tensioned by wedge, this is more convenient and reliable (5) The shaker deck can be adjusted. Adjustment will be realized by adjusting worm whirl. There is worm whirl at each side of shaker deck. Middle shaft connect two whirl pipe, when we make adjustment, two sides will be compliant and in-phase (6) The paint of shaker is processed by grit blast, use high anticorrosive zinc rich coating. Will make shaker surface anticorrosive and more beautiful 5. Lifting, transportation, installation 5.1 Lifting When we lift the shale shaker, we need to handle it by lifting specific lift ring. There are 4 lift rings totally. Users should not attempt lifting by attachment to any other location to avoid breaking equipments Warning! Do not make lift rope on any pipes nor vibration motors, and ensure the equipment are at even level when lift 5.2 Transportation Refer to fig II there are four sets tension device. It including M20 tension bolts, cover, mat, gasket, and M20 nuts. When deliver the shaker, the tension devices are tensioned. This will keep equipment stable and safe during transportation to avoid any broken on shaker. When shale shaker arrive at job site, and finish installation the tension device can be released (Refer to Fig III). When we release it must keep M20 bolts, cover, mat, spring gasket and M20 nuts well to ensure every handling the shaker will be stable and safe. Note: When running equipments, the shipping brackets must be uninstalled Fig II. The tension bolt in tensioning Fig III. The tension bolts released 5.3 Installation When shale shaker arrives at job site, make it at proper position and according to installation hole with sign of 4-Φ23 ( Refer to Fig I ). Make fixture, do related position fixing on all aspects to make installation, uninstall. If along with system, we’ll provide installation and fixture, user only need to connect and fix it Connect electric power to shale shaker magnetic starter. Usually, the electric system will be 380V/50Hz. The vibration motor and magnetic starter can be customized according to clients’ requirement There is button signed “ON”, “OFF” and have certain colour for identification. Shale shaker can be installed on even operation plate. The shale shaker can be designed as tandem shaker, and even more. But should make suitable connections and related pipes.
