GN Solids Control is a leading construction mud treatment system provider with customers from over 85 countries and regions. Several weeks ago, GN engineer visited one Australian construction company and got a very positive feedback on the GN mining vibrating screen and decanter centrifuge’s excellent working performance.

1.GN Mining Vibrating Screen
GN Solids Control manufactures different types of vibrating screens, such as dewatering screen, classification screen, stack vibrating screen, large linear vibrating screen, large banana vibrating screen etc.
GN Solids provides one sets of dewatering vibrating screen for this Australian construction company who owns more than 20 sets hydrovac trucks that can bring min. 100 tons slurry or waste from different sites.

This vibrating screen is especially designed to remove big particles larger than 2 mm before feeding into GN fine shaker unit (includes a double deck fine shaker and a desilter). A big catch hopper is able to collect two hydrovac trucks to dump at the same time, and a manual control gate valve to adjust the dump feeding volume into the big vibrating screen.

2.GN Decanter Centrifuge
GN decanter centrifuge is especially designed to remove the finest particles from the hydrovac slurry, with a big G force upto 3000 G, silts larger than 2~5 microns can b recovered.

As for this construction company, GN Solids Control provides one 22 inch bowl decanter centrifuge, which is able to treat at least 30 m3/h slurry with 20 % solids content. To help the centrifuge use a long time without weariness, GN Solids Control use tungsten scrapers and inserts to protect the solids discharge ends. Optional flushing lines can be also built on the centrifuge’s collect box to flush the solids discharge ends and reduce the solids abrasion.
GN Solids Control has rich experience to provide solids and liquid separation for varieties industries, welcome to reach to GN for the most cost-effective solution.

GN Solids Control shipped 3 sets double deck linear motion shale shakers and 1 set mud cleaners to one European drilling rig contractor last weekend. With these years’ upgrading, GN Solids Control now provides the F version shakers with the most satisfying working performance and convincing quality.
All these GNZS706 shakers that GN Solids Control manufactured are double deck shakers with totally 6 pcs (each deck 3 pcs) screens: tob deck working area is 2.0 m2 and bottom is 2.6 m2 which is 4.6 m2 working areas.

When a GN shaker is fixed with 2 decks’ screens, usually the top layer is the coarse deck which can remove big particles, and the bottom layer play as the second step to remove finer particles. However, when a shaker fixed with hyhrocyclones, the working process will be different, bottom layer separation first before feeding into cyclones and then the top layer screens separate again.
This European drilling contractor has some old NOV Brand VSM 300 shakers before, when they are considering to upgrade them they choose to use GNZS706 double deck shakers.

GN Solids Control made GNZS706 double deck shaker, easy and convenient to replace new screens by the fast wedge press units, save at least 30% total to replace screens compared to the tradition method.
With a large separating room, GN Solids Control shaker GNZS706 runs under linear motion with max. 7.2 G force, meet the demands of drilling mud solids control for large onshore drilling rig and offshore drilling rig during fast exploration.
GN Solids Control manufactures and sells over 300 sets shale shakers every year, besides these standard equipment, GN Solids Control also provides turnkey customized systems with multiple shakers or mud cleaners fix on the top of a mud tank, includes all in and out pipe lines, with centrifugal pump fixed on the tank bottom, and mud agitator or mud hopper on the mud tank for option usage.

GN Solids Control is a global solids and liquid separation equipment provider that has thousands of systems running successfully. This month GN Solids received another high comments on one hydrovac slurry dewatering system that provided 14 months ago.
GN hydrovac slurry system mainly includes the following treating components: feeding hopper, coarse shaker, fine shaker, desilter and decanter centrifuge.

GN Solids Control has provided dozens of hydrovac slurry dewatering system in US and Canada, as well as Australia and New Zealand. It helps hydrovac excavation contractors to save huge money on the slurry investment, and more importantly bring extra profit as those recycled pebbles, sands, silts can be resold. GN designed whole hydrovac slurry dewatering system is a close treating unit, water recovered in this system can be used to flush the hydrovac truck or dilute the transported slurry.
A large catch hopper can hold 1-3 hydrovac trucks dumps at the same time. GN Solids designed coarse shaker is a dewatering type linear shaker, fixed with long life PU screens, all big stones can be removed by this dewatering vibrating screen.

After treated by GN coarse vibrating screen, underflow slurry is feed into a GN fine shaker to get sands, and later slurry is feed into GN 4 inch cyclones to remove solids larger than 25 microns. GN Solids Control provides a standard 40 ft container to hold all the treating units.
GN decanter centrifuge GNLW553 is a 22 inch bowl centrifuge, able to recover almost all the solids larger than 2-5 microns. With the help of GN automatic chemical dosing unit, GN decanter centrifuge can separate even finer particles.

GN Solids Control has rich experience to provide customized solids and liquid separation systems. Professional commission engineers are able to provide timely technical support to help customers setup the system and train the onsite operators how to run and maintain GN system.
