GN solids control developed a new product- mini shale shaker, model GNZS752. It can meet the requirement for the clients who do not need so large treating capacity, but want to find an economic way to separate big solids from the drilling fluids.

GNZS752 shale shaker with unit treating capacity 264gpm, 2 screen panels with total screen area 1.35m2, G-force 6.3G adjustable, total power of this shaker is only 1.0KW, and total weight 800 kgs. Based on these parameters, we called it mini shale shaker.

This linear motion shale shaker GNZS752 can be widely used in HDD, water well drilling , shadow drilling and other drillings which need small treating capacity. After the new mini shaker is developed, there are many clients showed their interests. Before they have to use bigger shaker 2-panel GNZS852 or even 3-panel GNZS703. These shakers can treat the drilling mud better because of their large treating capacity, but it is a waste of money.

Comparison between GNZS752 and Brandt mini Cobra 2-panel shaker

Motor power: Brandt mini Cobra is 1.1KW x 2 , GN mini shaker is 0.5KW x 2

Screen area: Brandt mini Cobra is 1.6m2, GN mini shaker is 1.35m2

Screen panel: Both of them are 2 panel

Screen type: pretension, repairable

Last week GN solids control shipped a unit of decanter centrifuge and feeding pump to Europe. Our equipments can meet the requirement of the clients who need high quality and more strict operation status.

The bowl decanter can meet the following features:

1 Electric motor and control panel are explosion proof and have ATEX certificate.

2 The decanter centrifuge can work both in 400V/50HZ and 440V/60HZ. When you finished the drilling operation in one site, you can only change pulley belts to use it in different electric ratings.

3 The control panel utilized in zone 1,exp standard is Eex deⅡBT6.

4 The centrifuge used in ATEX EX zone 2(CAT 3G), TEMP T3 hazardous area.

5 Erosion affected area to be protected with abrasion protection –Tungsten Carbide coated stainless steel parts.

6 Include a signal line, with equipment fitted for a local/remote switch and a signal stating to the remote locatation(SPDT contact) LOCAL status which shall block any remote functionality and a similar stating remote status which likewise shall block any local actions.

7 Nominal treating capacity is 40m3/h,actual treating capacity is 30m3/h.

8 The max rotary speed can reach 3200rpm in 60HZ.

Last week we shipped another set of decanter centrifuge to South America. GN solids control is a new star for South America market, there are several sets of centrifuge working in site in Colombia. Our improved high speed centrifuge GLW360x1250 has been proved in good performance in solids liquid separation.

GN improved decanter centrifuge has the following features:

G-force 2035G, separation point 2~5μm, differential torque 4000N/m max, bowl speed( during working) 3200rpm, differential ratio 57:1.

Bowl

The bowl has a cylindrical/conical shape and rotates at a pre-set speed optimal for the application. The slurry rotates with a different scroll design or by modifying an existing scroll. Scroll pitch and single or multiple flight configurations are important design variables.

Scroll

The scroll rotates at a slightly different speed than the bowl and conveys the deposited solids toward the conical end of the bowl.

Materials of construction

GN solids control uses high-quality stainless steel for all wetted areas. Bowl and scroll castings are made from centrifugal cast high strength and corrosion resistant stainless steel.
