How to select to use linear motion or elliptical motion shale shaker? Normally linear motion is applied to 1st and 2nd drilling phase, elliptical motion is applied to 3rd and 4th drilling phase, it varies according to the drilling depth. The main features of linear motion shale shaker is high G force, higher treating capacity when used same mesh shaker screen, large throw angle, it is suitable for low viscosity drilling fluids, high solids content, coarse solids size, hard drilling cuttings, higher flow rate. The features of elliptical motion shale shaker, lower G force, lower treating capacity, longer time stay on shaker screen, drilling cuttings are not easily broken, which is suitable for easy broken drilling cuttings.

When double deck shale shaker is used to treat oil sludge, water spray system will be installed to avoid screen blocking by the high viscosity oil sludge, top sealing cover will be installed to prevent it from splashing.
Compact design will lead the shaker screen replacement difficult, to reduce the screen replacement is very important, the composite material frame shaker screen can last longer time compared with metal frame shaker screen.

ViST Vacuum Screen
Sludge vacuum pump
Shale shaker and Shaker screen, the shale shaker is a 4 panel screen linear motion shale shaker, installed with shaker screen 585x1165mm, the total screen area is 2.73m2, the max G force is up to 7.6G, which is adjustable by adjusting the vibration motor Eccentric block. The shaker deck angle is reliable mechanical adjusting system and both sides can be adjusted simultaneously. The last panel shaker screen closed to solids discharged side is installed a ViST vacuum screen unit, the purpose is to reduce drilling waste and recycle drilling fluids, a suction hose is connected to ViST vacuum unit.

The compressed air from air compressor is required to create suction on the last screen surface, pulling additional fluids off the cuttings. It can reduce the liquid on the cuttings by 30-50%. The main components of the ViST vacuum unit consists of vacuum unit, catch pan, air supply inlet, shaker inlet, display screen, etc.

The sludge vacuum pump can be widely used to transfer drilling waste, drilling mud, hazardous waste, oil sludge, animal waste, sand, crude oil tank bottom cleaning sludge, and other industrial waste. Compare with other types electrical driven transfer pump, the vacuum pump is 100% air operated, no need electric power, it is suitable for hazardous area application, especially for refinery oil tank cleaning, the vacuum pump can be put into oil tank bottom to transfer the oil sludge out of the tank and send to oil sludge separation system .

The screw conveyor is designed to transport drilling waste from one place to another place safely and efficiently. There are many methods to transfer the drilling waste, but screw conveyor is a relatively economic and proven method among them. The benefits to use a screw conveyor is that low power consumption, continuous working which will reduce the requirement for collection tanks, require less operator to save labor cost, flexible to adjust the dimension for different transfer capacity. The scroll are made of wear-resistant and thicker manganese steel. the scroll can also be sprayed with wear-resistant coating to prolong the service life, the pull-wire switch can be installed on the conveyor to realize safety protection

The working principal of the screw conveyor is as below:
A scroll (also named auger) is rotated inside a trough driven by an explosion proof motor, when the drilling cuttings are fed into the inlet port of the screw conveyor and transferred along by the rotating scroll. The scroll is sealing inside the trough by a hinged metal lid/cover for safety.
The screw conveyor discharge port can be customized according to client’s requirement. The cuttings collection box can be installed under the discharge port for safe storage, or the high G drying shaker waste collection hopper, or the open top feeding port of the vertical cuttings dryer. The screw conveyor screw diameter and screw length can be customized as per transfer capacity and transfer distance requirement. the screw diameter could be 10 inch, 12 inch, 14 inch, 18 inch and the screw length could be 12ft, 24 ft, 36 ft, 48ft, each section is 12ft and you can select 2 section, 3 section, 4 section.

If you need a drilling cuttings transfer system, pls contact with GN solids control, we can design multi point discharge screw conveyor for container loading.

Recently one batch of mud agitators are ready for shipment to offshore drilling platform. The features of the mud agitators are as below:

1. The gearbox type is helical bevel gearbox
2. The motor and control panel are connected by coupler, our normal connection method is direct connection.
3. The motor and control panel is comply with ATEX explosion proof for offshore application.
4. 
   The Heavy Duty E version mud agitator is suitable for Oil Based Mud, Water Based Mud, Synthetic based Mud. If you need more compact footprint mud agitator, we will recommend G version mud agitator, which is also heavy duty mud agitator but the motor and gearbox is helical bevel gearbox. Compared with worm wheel type gearbox, the helical bevel type gearbox is more reliable and with high efficiency, especially suitable for heavy mud agitating. The major components including gearbox, explosion proof motor, star elastic coupling, guard cover, mounting plate, agitator shaft, impeller, stabilizer. Replace lubricating oil in the gear box every 1000 hours, Brand of lubricating oil: Mobil: olilgear 630 or Mineral lubricant 220# (when the ambient temperature is -10~40℃) or synthetic lubricant 220# (when the ambient temperature is -25~80℃); replace grease in the motor every 2500 hours, Brand of lubricating grease: Mobil: EP2.
   What is the difference between worm reduction gearbox and bevel helical gearbox?
   In working principal and applications, the worm reduction gearbox is widely used for chemical mixing, the helical bevel gearbox is suitable for application which required high torque and efficiency ratios.
   Except for mud agitator, GN solids control also provide mud gun, mixing hopper, centrifugal pump, slurry pump, etc. equipments, we can design customized mud tank system with proper schedule of mud agitator, mud gun, pumps, etc. if you need mud agitator and pump, pls contact with GN solids control.

According to the required treating capacity and maximum density/ viscosity of the drilling fluids, the user can select different numbers of high performance linear motion shale shakers. For example, normally 1000gpm treating capacity at 15cP will select 3 units shale shaker, 2 units in operation and 1 unit as back up. Sometimes as per client’s requirements, they can use 2 units of shale shakers, we have 3 panel linear motion shale shaker, 4 panel shale shaker ( linear motion, dual motion for option) for selection. E.g. when required treating capacity is 1200gpm at the same viscosity, they may also use 3 units of solids control shale shakers, single layer, 3 or 4 panels shaker screens, linear motion or dual motion as per required.

We can produce tandem shale shaker to install 2 units shale shaker on one skid with possum belly and pipelines, also we can produce triple shale shaker to install 3 units shale shaker on one skid with possum belly and pipelines, valves, arrangements. The package design is for easy transportation, easy operation.
Solids control shale shaker is the equipment to separate the solids based on physical size, which is decided by the shaker screen mesh size (the screen opening size ). The further phase separation equipments, such as desander cone, desilter cone, decanter centrifuge, separated based on the difference between fluids and relative weight.
GN designed shale shaker are all installed with composite material frame shaker screens, the dimension is different based on different models. Except for single layer shale shaker, we also produce double deck shale shaker when required treating capacity is very high. Right now GN solids control have one batch of solids control shale shakers in stock for sale, if you need high performance linear motion shale shaker urgently, pls contact with GN Solids.
