Desander Desilter

One unit of Hydrovac excavation waste slurry treatment system is shipped to Canada, the function of this treatment system is to recover the water and remedy the soil, the environmental protection regulation is very strict in North America, we already have 2 units of such hydrovac excavation waste slurry treatment working in the State.

The slurry treatment system is consist of equipments below:
1) Waste collecting hopper:
The waste collecting hopper collect the waste slurry discharged from hydrovac truck.
2) Course solids washing tank
The coarse screen under waste collection hopper will separate the big size trash and other mass firstly before feeding to the high G drying shaker.

The high G drying shaker with GN brand composite material frame shaker screens will separate most big size solids and reduce the solids content before feeding to the desilter cone.
3) Fine solids washing unit
Fine solids is separated by desilter cones and the solids is drying by the bottom drying shaker so the discharged soil will be drier for disposal and more fluids will be collected.
4) Dewatering centrifuge unit

The dewatering centrifuge is 22 inch big bowl big volume centrifuge with feeding pump and telescopic skid. The result will be better by using chemical dosing system. The ultra fine solids below 2 microns will be separated by decanter centrifuge with dewatering unit.

This week GN solids control shipped 2 units of Large Bowl 30 inch GNLW764A Decanter Centrifuge for Mining Industry to Australia, this is the largest centrifuge model we have made right now, we have 9 inch, 14 inch, 18 inch, 22 inch and 30 inch bowl decanter centrifuge with different treating capacity, different speed, different G force for various applications.

The diameter of the centrifuge bowl is 760mm, the bowl length is 3328mm, the treating capacity is 528gpm, max bowl speed is 2650rpm, typical bowl speed is 2200rpm, max G force up to 3000G, typical G force is 2060G. The main power is 160KW, back drive motor is 90KW, the gearbox Torch is 25000.N.M.

Same with the smaller decanter centrifuge, the screw propeller protection is tungsten carbide tiles, the bowl fluids distribution port and solids discharge port is protected tungsten alloy for longer working life, the bowl material is made of duplex stainless steel 2304 for anti corrosion.
The bearing for this big bowl centrifuge is very big, need separate lubrication system for better lubrication to extend the working life of the bearings. The plate type heating exchanging system can effectively cool down the lubrication oil so that to get a better cooling performance and the temperature sensor installed on the bearing seat will send signal to the PLC to trip off the centrifuge in case of over high temperature.

We shipped several units of screw conveyor to Africa for drilling cuttings transferring, this is not the first order from this client, they repeat order every year including shale shaker, desander, desilter, centrifugal pump, screw conveyor, etc.

We always provide the best quality, best service and best after sales support to our clients, that is the reason we got repeat orders every year from our old clients.
The screw conveyor is one method to transfer the drilling cuttings to drilling waste management system, when the drilling cuttings are from solids control equipments, screw conveyor is workable. If the fluids content is bigger and the drilling cuttings are not treated by solids control equipments, the pump is workable to transfer the waste. The auger length and diameter is customized according to the required transfer capacity and the distance between the waste and the drilling waste management system.

Except for screw conveyor, we also shipped shale shaker and poor boy degasser to Africa. The 4 units of poor boy degasser ( also known as mud gas separator), which is used before shale shaker as well control equipments, to separate the hazardous gas from the drilling mud to prevent it from kick off. According to the drilling depth, we can use different size mud gas separator, the standard size is 1000mm diameter, we also have 600mm, 800mm, 1200mm diameter for option.

ViST is Vacuum Shaker Screen Technology is to work with shale shaker to reduce drilling waste and recycle drilling fluids. This is technology developed by GN solids control, you can see the working video to understand clearly from GN website: http://www.gnsolidscontrol.com/vist-vacuum-screen

The unit is installed under the last screen of the shale shaker or installed externally of the shale shaker. It needs a air compressor to provide air supply for operation, most of the rigs will own one air compressor, no need to buy extrally. The air will create suction on the last screen of the shale shaker, reduce the liquid on the cuttings by 30% to 50%, separation of the fluids out of the cuttings.
It increased the recovery of useful drilling fluids, reduce the drilling cuttings volume, drying the drilling cuttings, so the vertical cuttings dryer working efficiency will be increased, the user will save a lot of the drilling waste treatment cost, and save more cost to prepare for new drilling fluids, so you can be benefit to use ViST vacuum shale shaker screen technology. Compared with the cost to use more drying shale shaker or drilling waste management system, the benefit to use ViST vacuum shaker screen is as below:

1)    Compact design, no need more space to install one more shale shaker or drilling waste management system, the result is to reduce the liquid 30% to 50% of the drilling cuttings for both WBM, OBM or SOBM
2)    Competitive price compared to use more equipments, including screw conveyor to transfer the drilling waste to drilling waste treatment system

This week GN solids control shipped 9 sets of shale shakers to Shandong client, this is their repeat order. We have several models of shale shaker for option:

1)    3 panel shale shaker, GNZS703F with 2.63 m2 total screen area is one of the best sold model among all the models. the 2 vibration motor provide high G force up to 7.5G, the adjustable deck angle adjustment system allow the operator to adjust the deck angle for different purpose during operation, you only need to adjust from one side, then the other side is also adjusted automatically, some other brand shale shaker will need 2 operators to adjust the deck angle at the same time from 2 sides by using same deck angle, it is inconvenient for operation.

2)    4 panel shale shaker, GNZS594F with 2.73 m3 total screen area, the screen dimension is 585x1165mm, the reinforce durable composite material shaker screens are interchangeable with world famous brand shale shaker, the 2 vibration motor provide high G force up to 7.5G, it can separate the solids better so the drilling mud can meet the drilling requirement
3)    2 panel shale shaker GNZS752 with 1.35m2 total screen area, also installed with composite material shaker screens, the working life is 2 times compared with the previous steel frame shaker screens. It is very easy to replace the shaker screens, the operator only need to use the special tools Ratchet wrench to loose the locking wedges, then put the screens on the shaker deck, then use the wrench to lock it again. The whole process did not take 20 seconds, very fast.
