Recently we have one batch of composite material frame shaker screens ready for shipment for a international drilling companies. We packed 18pcs screens at each plywood pallet, each piece screens packed by GN standard design paper box, we can also provide neutral paper box as per client’s requirement.
GN shaker screens are produced as API RP13C standard and have test report from API authorized agent in America. We can produce shaker screens from API 20 to API 325, the mesh size over API 60 all adopted 3 layers stainless steel wire mesh for better strength. The composite material frame lasts longer working life than steel frame screens, and larger effective screen area for better separation performance.
Shale shaker is the first phased cleaning equipment at solids control system, shaker screens are consumption parts of shale shaker, the user always make proper stocks for the shaker screens for convenient operation, the composite material frame screens can be storaged up to 5 years without getting rust. Based on different drilling fluids, the shaker screens working life will be different. The composite material shaker screens are repairable with plastic plug. The 3 layers 4-sides pretensioned wire mesh before heat pressing will provide enough strength. We can make customized color for the composite material frame as per client’s requirement. We adopted wedge as shaker screen locking system, the user can replace the shaker screens easily and fastly, the user can use the ratchet wrench to lock and release the wedge and take the shaker screens easily. The shaker deck angle can be adjusted by both sides simultaneously from -1ºto +5º. When install the desander and desilter frame on top of shale shaker, the 3 in 1 mud cleaner as the second phase cleaning and the third phase cleaning equipment. The desander cone and desilter cone are 100% PU wear-resistant material.
Recently we shipped one batch of mud agitators with control panel to Middle East client. The mud agitator is installed on top of the shaker tank to stir the drilling mud and prevent it from solids precipitation. These mud agitators are installed for liquid mud plant to mix and storage drilling fluids, the user can produce the mud tanks locally to save freight cost and importation cost. The control panel is installed besides the mud agitator for convenient operation, this is GN OEM control panel with our own explosion proof certificate.
The gear box and explosion proof motor is connected directly, this is compact design to be suitable for mud tank which have limit space to install the equipments. When the client need to install their own motor to match the local explosion proof class, we will provide gearbox connected with coupler, one side is connected with gearbox shaft, one side will be connected with the client’s motor, we only need to check the installation drawing of the motor in advance to confirm the suitability. Normally we install the mud agitator on the tank every 3 meters, this is not fixed, will be varies with different drilling fluids conditions.
The mud agitator will be controlled by the control panel installed on one end of mud tank, and ON/OFF SWITCH will be installed besides the mud agitator for convenient operation, the user can control the on/off/emergency stop of the mud agitator easily when it is necessary. The mud gun will be installed to work together for agitating the drilling fluids to prevent it from sediments. We can provide mud agitator, mud gun, centrifugal pump, mixing hopper, shale shaker, mud cleaner, vacuum degasser, desander, desilter, etc. equipments to the mud tank manufacturers locally, they can produce mud tank and use our equipments.
2 units of 30 inch big bowl decanter centrifuges are shipped to USA for construction slurry treatment. This is the largest model decanter centrifuge we produced right now, it is widely used for construction, TBM, etc. projects which required big volume treatment. Same with other models decanter centrifuge, features of GN big bowl decanter centrifuge:
1) Bowl material is made of duplex stainless steel 2304 or 2205, the cone bowl is made of stainless steel 316L, the screw is made of SS304 by 1000 degree heat treatment. The open impeller can increase the treating capacity and treatment efficiency a lot.
2) The screw impeller is protected by tungsten carbide tiles, which is repairable once it is damaged. We do not use welding spray tungsten carbide alloy because it is easy to be damaged and once damaged, it can not be repairable, the user has to replace the complete screw unit. 3) The main bearings are SKF brand for longer working , especially after long time rotating, the bearing temperature will become very high, it is easily burnt if the bearing quality is not reliable. 4) 2 ea motor including main motor, back drive motor are installed on one side of decanter centrifuge to save space and for compact design. 5) Centrifuge VFD control panel with 3 motors variable frequency including main motor, back drive motor and pump motor, the 3 inverter with world famous brand for convenient outsourcing, the positive pressurized VFD control panel can be used in high temperature environment compared with normal explosion proof VFD control panel, it is easily break off in hot weather for the normal explosion proof control panel, positive pressurized VFD control panel can prevent it from such problem. If you need big bowl big volume decanter centrifuge, pls get more information from GN solids control.
