Drilling Mud Recycling System

Recently GNSP-40B and GNSP-10B sludge vacuum pumps are ready for shipment for drilling waste cleaning to Africa. The application of vacuum pump used at drilling rig site including: drilling hazardous waste cleaning, waste pit cleaning, mud tank cleaning, drilling rig platform cleaning, drilling cuttings transfer, etc.

When the vacuum pump is used as drilling cuttings transfer, it can be used as screw conveyor, which will collect the drilling cuttings from primary solids control equipments, such as shale shaker, desander, desilter, decanter centrifuge, etc. The usage of vacuum pump and screw conveyor is according to space limitation, vacuum pump needs less space for installation, the max suction distance is 50m, the max discharge distance is up to 1000m, it is 100% air operation pump without electricity power supply, just it needs air compressor for air supply. The screw conveyor needs large area for installation, and the transfer distance is very limited, and the power consumption is also high. In actual situation, the user can use both vacuum pump and screw conveyor together, the drilling waste is collected in a collection hopper by vacuum pump and transferred by screw conveyor to drilling cuttings treatment system vertical cuttings dryer and decanter centrifuge for drilling cuttings treatment and cleaning.

When the vacuum pump is used for drilling waste and waste pit cleaning, there are automatic mode and manual mode for option, and connect suction pipe, discharge pipe and air hose with air compressor, if automatic mode is selected, set the suction and discharge time after running the vacuum pump for several loops. The maximum solids size for GNSP40B vacuum pump is up to 75mm, waste solids content is up to 80%.We also provide different type suction pipe and discharge pipe to transfer different waste material with different length, each section length is 10m with joint.

The equipments are with customized painting color and client’s LOGO. All of the equipments can be installed on the client’s mud tank and connected by bolts easily. If required, we can also design customized drilling rig solids control system for client’s different requirement.
Except for shale shaker, mud cleaner, decanter centrifuge, centrifugal pump, GN solids control also produce vacuum degasser, mud agitator, mud gun, mixing hopper, submersible slurry pump, mud tank, mud gas separator, etc. solids control equipments, we can also produce dewatering centrifuge, vertical cuttings dryer, screw conveyor, sludge vacuum pump, etc. drilling waste treatment equipments.

GN mining vibrating screen, shale shaker and decanter centrifuge, desilter cleaner are used for Australia construction mud treatment. The construction mud treatment system including:

Mining vibrating shaker , the function is to separate stones, construction waste, branches, etc., so that big solids will not be feed to further process and block the equipments.

The high frequency fine vibrating screen, the function is to separate the coarse solids and reduce solids content. The composite material frame shaker screen is used to separate the coarse solids from to construction mud. We can produce different API mesh size screen from API 20 to API 325 according to your requirement. The high frequency fine vibrating screen is designed for classification, separation and dewatering application of wet or dry screening.

Desilter mud cleaner, the function is to separate the fine solids from the construction mud, the separation cut point is 15~40 microns. The qty of desilter cone depends on required treating capacity. The bottom shaker installed composite material frame shaker screen for drying the discharged solids and recycle more useful fluids.

Decanter centrifuge, the function is to separate the fine solids cut point 2~5 microns, working with flocculants from chemical dosing unit, most of the ultra fine solids can be separated out, the recovery water can be reused or sent to waste water treatment plant for further treatment. The previous separation has separated most of the coarse solids and reduce solids content to proper content so that the centrifuge can work properly without blocking the screw.
The solids discharged from mining vibration shale shaker, high frequency fine vibrating screen shaker, desilter mud cleaner, decanter centrifuge can be collected by waste collection box and easily transported to other place. If you need a customized construction mud treatment plant, pls contact with GN solids control.

Recently one batch of GN new type J version solids control shale shakers are ready for shipment to overseas client.
The features of new type J version solids control shale shakers as below:

The bottom sealing rubber adopts new patent technology, convenient to replace, wear resistant polyurethane rubber strip wit good sealing effect and longer working life.

It can meet the requirement of drilling fluids shale shaker and mud cleaner with spill proof cover for option.
It meets the requirement of shale shaker installed ViST vacuum unit for option, to change the shale shaker to negative pressure shaker.
It is convenient to adjust the shaker deck angle, after angle adjustment, it can be locked to avoid loose.

the shale shaker stainless steel deck bottom rubber support system, to meet the long time anticorrosion for offshore drilling.

High strength imported famous brand spring, with good performance and longer working life.
The shaker screens installed on the shaker and mud cleaner is 585x1165mm composite material shaker screen, the total screen area is 2.73m2, 2ea of Italy Oil brand vibration motor drived the shale shaker and generates max 7.5 G force. During the transportation period, the shale shaker is locked by locking bolt to protect the shaker deck, once arrived at the jobsite, the locking bolt should be removed before start.

The different qty of desander cone and desilter cones assembly are installed on the mud cleaner as 2nd phase separation and 3rd phase separation. The bottom shaker model of mud cleaner is same with shale shaker.
Except for 4 panel shale shaker, we also produce 3 panels shale shaker, 2 panel shale shaker, double deck shale shaker, high G drying shaker, tandem shale shaker, etc., if you need a solids control shale shaker, pls contact with GN solids control.

One batch of mineral exploration core drilling decanter centrifuge package are ready for shipment to Europe client.

The core drilling centrifuge GNLW223 is installed on top of fluids collection box, if the user can confirm the coarse solids has been separated out before feeding to the decanter centrifuge, they can feed the waste slurry to decanter centrifuge directly, the fine solids are separated out from decanter centrifuge, the fluids dropped into the collection tank which can be reused for drilling directly or mixed with chemical additives to be reused for drilling rig.

The 9 inch mini decanter centrifuge has been widely used for mineral exploration core drilling for water recovery. The purpose to use the core drilling decanter centrifuge is for environmental protection, more water recovery, less water consumption, less drilling cost, reduce cost for waste treatment. The model number is GNLW223D and GNLW224E-VFD, the max treating capacity for water is 130L/min, for slurry treating capacity, it is up to 100L/min. The bowl diameter is 9 inch (220mm), max bowl speed is up to 4500rpm, typical bowl speed is 3800rpm, max G force is 2492G, typical G force is 1777G, main motor power is 11KW, gearbox torque is 500 N.M. If VFD decanter centrifuge is required, for example, to use in high mountain condition, we can use a VFD control panel with the decanter centrifuge.
If the solids content is high and remained coarse solids in the waste slurry, a shale shaker is suggested to use before decanter centrifuge. GN designed solids removal unit including picking up pump, mini shale shaker, mini decanter centrifuge with feeding pump, mixing hopper with mixing pump, mud tank and control system. As per requirement, the generator can be installed on the tank skid.
If you need a core drilling centrifuge, pls contact with GN solids control.
