Shale shaker operation and maintenance

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.

2 shale shaker maintenance

(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.

(6) Inspect entire machine for evidence of coating damage, including exposed base metal, corrosion, deep scratches, or other voids. Repair damaged areas in accordance with coating manufacturers’ specifications.
