Large Bowl 30 inch GNLW764A Decanter Centrifuge for Mining Industry to Australia

Dec 20 2018

This week, GN arranged the shipment of two sets large bowl decanter centrifuge to Australia for coal mining slurry dewatering process.

The model of the large bowl decanter centrifuge is GNLW764 that is the largest centrifuge GN can make at this time. For the coal slurry dewatering project, always a large flow capacity is required. That is why the client selected GN largest decanter centrifuge.

Features of GN Large Bowl Decanter Centrifuge GNLW764A

1. The rotating bowl is made from duplex stainless steel 2304 with centrifugal casting processing for better balance performance.

2. Screw conveyor is also rom stainless steel and the blade is protected with tungsten carbide for long working life.

3. To protect the motor of the large bowl decanter centrifuge. GN equips the VFD control panel for the operation of the centrifuge. So that the motor can be started to run at a low speed to prevent the over high electric current to burn the motor. In the meanwhile, a VFD control panel will let the operator to run the decanter centrifuge with different speed for various process purposes.

4. The lubrication system is using oil pump to feed lubricants to both of the bearing seats. 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.

GN decanter centrifuge is mostly used in drilling mud solids control. However, now is applied in more and more other industries like mining slurry dewatering, waste water treatment and oily sludge treatment. For more information on GN big bowl decanter centrifuge, please contact us freely.

14 Inch decanter centrifuge

The GN 14 inch (360mm) diameter bowl decanter centrifuge which has a length over diameter ratio of 3.5:1 with high speed up to 4000 RPM. The centrifugally casted duplex stainless steel bowl and the tungsten carbide hardened tiles on the solids conveyor maximize the GNLW363 centrifuges operational service life between overhauls. The GNLW363 features replaceable ceramic/tungsten carbide inserts at the feed distribution and solids discharge zones. The unit also has Tungsten Carbide plows to continuously clear the solids discharge area. All bearings fitted to the GNLW363 centrifuge are SKF premium brand bearings for extended service life and reliable operation

Shale Shakers and Decanter Centrifuges for Russia Drilling Rig

After a whole day packing and marking labels, GN just shipped out one batch shale shakers and decanter centrifuges to equip the oil well drilling rigs in Russia. Shale shaker and decanter centrifuge are two of the key equipment in drilling mud recycling system. The shale shaker separates the cuttings by using the wire mesh screen opening size to block the coarse cuttings, while the decanter centrifuge is separate ultrafine solids by using centrifugal force.

GN shale shaker could be used in drilling mudsolids control system as the primary shaker unit and also as the high G force drying shaker in waste cuttings management system.

Below features make GN shale shaker the reliable performance in using

1. Shaker vibrating deck is completely heat treatment for higher vibration G force

2. Shaker is installed with GN self-produced composite frameshaker screen with longer working time.

3. Patented rubber sealing installation method make the replacement of rubber strip much easier and better sealing performance.

GN decanter centrifuge could be used in drilling mud solids control system for fine solids separation like the suspending barite recovery and useless cuttings removing. In the waste cuttings management system, the high speed decanter centrifuge could be used to treat the effluence discharged from the cuttings dryer. Besides the petroleum industry, the decanter centrifuge is also widely used in mining and environmental protection industry.

The decanter centrifuge shipped to Russia in this order is the popular 14 inch model with designed maximum speed up to 3900RPM. It could be control as fixed speed or variable frequency.

Below features make GN decanter centrifuge excellent performance.

1. Bowl material is from duplex stainless steel 2305 with good machinability.

2. Centrifugal casting technology makes the bowl material distribution evenly for a good dynamic balance.

3. Tungsten material tile or bushing protection at abrasive part for longer working time and less maintenance.

4. PLC control panel is available, and the sensors could be put on the centrifuge unit to monitor the status of the machine.

9 Inch (220) Decanter Centrifuge – Baby Centrifuge

GN design and manufacturer different size of decanter centrifuges for industry separation. Solid bowl decanter centrifuges have been operating according to the same basic principle since 19th century.GN centrifuge production line is from 9 inch (220MM) bowl to 30 inch (760mm) bowl, with bowl length and diameter ration up to 4.2, and the adjustable G force is up to 3000G to meet different industry separation applications

The 9 Inch Decanter Centrifuge is a baby centrifuge which is the world smallest industry decanter. The bowl of the centrifuge is 9 inch (220mm). As the compact design, it’s popular for client to use it in small capacity or limited space application for solids and liquid separation
