In drilling mud solids control system, the
mud agitator is one type of very important equipment widely used in the active mud
storage tank to make the solids suspension to avoid settlement down to the tank
bottom. As a leading manufacture for solids
control equipment, GN solids control provide the mud agitator from 4 hp to
30 hp, the bearing used are from FAG and the oil seal is from SOG. GN’s mud
agitator is direct connection type for the motor and gear box, which makes the
structure more compact.

How to choose the right model of GN’s Mud
Agitator

By choosing the suitable model of the mud agitator, GN always
needs know how the inner dimension of the mud tank or mud pit is. Thus GN’s
engineering team would propose the right agitator shaft length and the size of
the impeller. If the mud density could be provided, that would much helpful for
GN to suggest the horse power of the motor. Generally, the heavy much may
request a high power.

How to Install the Mud Agitator

GN’s mud agitator always has the mounting
skid on which the gear box and motor are installed. This design makes the mud
agitator unit more stable if it is installed on the mud tank.  GN’s mud agitator unit will be divided into
pieced for easy delivery. Always, the gear box and motor will be as assembling
package for delivery. The shaft and impeller will be disassembled and packed in
other crates. When install the mud agitator on mud tank, the gear box and motor
assembling is lift and put on the tank top where there has already a hole for
agitator shaft insert into inside of the tank. The shaft was straightly and
vertically bolted to connect with the gear box. For the shaft longer than 6”,
the agitator unit is provided with tank bottom stabilizer to fix lower end of
the shaft to prevent vibration during working. GN can provide the agitator with
one and tow impellers as per the tank depth. The location of the impeller on
the shaft is determined as a height from the tank bottom to the impeller. GN recommends
the distance 0.75 times of the impeller diameter. For example, a 20” impeller should
be mounted 15” above the bottom. GN recommends straight impeller blades for tanks
under 5’ deep and canted blades for deeper tanks. If dual impellers are
desired, straight blade should be mounted on the bottom and the canted blade
impeller is installed at a point about two-thirds distance above the tank
bottom.

In the recent days, 4 sets of shale shaker
together with a large batch of shaker screens are ready for delivery to UAE. It
was a repeated order for one of GN UAE client with which to replace the old
shale shakers in the existing solids control system. Each year, Hebei GN Solids
Control Co., Ltd manufactures around 250 sets shale shaker because of its
popularity in the international market with high quality and competitive price.
This time, the customer also ordered a large batch of screens.

GN shale shaker is fixed with 2, 3 or 4
panels of screens with different designed treating capacities. Frankly
speaking, the most popular model is 3-panel. GN shale shakers owns the below
advantages.

1.      
Screen bed is made of stainless
steel to extend its service life and improve its performance.

2.      
Shaker motors come from Italy
Oli or Martin; electric control components come from SIEMENS or Schneider.

3.      
Whole deck is heat-treated to
ensure it works stably and safely at high G force up to 7.5 G.

4.      
The screens are locked by
wedges so to speed up the screen-changing process.

5.      
Rubber sealing is adopted between
screen and bed to avoid fluids overflowing and leakage.

6.      
Three options for feeding are
available with weir feeder, box feeder and hopper feeder.

Besides manufacturing screens for GN shale
shaker, GN Solids Control also manufactures and supplies replaceable screen
with famous brand shale shaker such as Derrick, MI-Swaco, NOV Brandt and so on.
GN screens are of high quality because the raw material comes from the same
supplier to Derrick screens, and the glues used to stick the screen are
imported from Canada. High Quality Product has always been GN pursue and
promise to our customers.

Good drill solids control is very important to a drilling capacity. Generally, there are three ways to control the drill solids: dilution, gravity setting and mechanical removal. While the essay will only focus on the last one mechanical removal with an introduction of GN solids control equipment. As its name tells us, mechanical removal means to separate solid with mechanical equipment. Because of various particle sizes, there will be various phases of equipment.  The equipment can be classified into two main groups. The one is sieving device, the other is centrifugal separation device. The sieving devise could separate particles with a size of 61 microns by a 250 mesh screen. The centrifugal separation device hydrocyclones could removal particles between 20 microns to 70 microns with different size cones. The centrifugal separation device decanter centrifuge is to remove the colloidal particles up to 5 microns. 

Hebei GN Solids Control is a specialized and top manufacturer of mechanical equipment to control drill solids. With a few years’ development, the brand GN Solids Control has been achieved. GN Solids Control has its shale shaker as the screen device which is used in the primary phase equipment to separate coarse solids. GN hydrocyclone products such as desander , desilter, mud cleaner and the decanter centrifuge are machines to separation solids by centrifugal forces. GN desander with 10’’ cones could separate solids over 40 microns; GN desilter with 4’’ cones could separate solids over 20 microns; GN mud cleaner is the combination of the desander and desilter to save space. GN decanter centrifuge is used to separate ultra fines solids between 2 to 5 microns with G force produce by high rotating speed. GN Solids Control product is of high quality with cost effective price.

Regarding to the mud recycling system for HDD drilling,
It generally includes 2 or 3 phase treating machines with mud mixing devices.
If it is with 2 phases, the first phase will be shale shaker to separate coarse
solids and then desander cones or desilter cones to separate fine solids. If
with 3 phases, the first phase will be shale shaker,
the second will be desander cones, the third will be desilter cones. Regarding
to the mud mixing device, it is mud mixing hopper with mud mixing pump. In GN,
the standard models are divided by the treating capacity from 200 gpm to
1000gpm, so we have 200GPM, 350GPM, 500GPM, and 1000GPM. Unit till now, over 20
sets operate in Australia for HDD and CBM drilling, also GN delivered one set
