4) Furthermore, some 14 inch high speed decanter centrifuges are shipped together for a full package solids control processing.

As the top solids control manufacturer in China, GN Solids Control becomes a more and more famous brand in China and at aboard. GN Solids Control are mainly compete with U.S and European brands.
Besides the full line solids control equipment manufacturing. Another big advantage of GN is that:

1) GN Solids Control is specialized on drilling waste management solution. GN major products include high G shale shaker for water base mud, Vertical cutting dryer for oil base mud, big bowl centrifuge, 3-phase disc centrifuge, solidification unit, thermal desorption unit, GN can offer clients one-stop pitless solution at rig site. After the drilling is finished, there will be not pit at the site.

2) GN Solids Control has his own screen manufacturing plant. GN is capable to make screens suit for all GN own design shaker and to other famous brand shakers.

Rotor assembly is the rotating part of vertical cuttings dryer. There are scrapers between the rotor and screens basket to help for solids removing. So the scrapers are wearing parts. Manufacturer will suggest to change the whole rotor assembly with a full set scrapers. Many customer cannot understand, why the rotors are not wearing parts, but have to change together with the scrapers?

The reason is that:

The scraper is with a curved surface. Although it is a precision casting, it has machining deviation. There are mounting holes on the scrapers after casting. The rotor is also a curved surface, and the rotor itself has no standard mounting holes for scrapers.
During assembly, put the scraper on the rotor to find the best place where the curved surface of rotor and scraper can touch well, and then drill holes on rotor for fixing. After 8 scrapers are fixed to the rotor, the whole unit will be machined and do dynamically balance. Because both precision casting and assembly have deviations. Therefore, the mounting hole positions on every rotor will be not the same. And the dynamic balance can only fit the original scrapers which delivered together from the factory. That’s why the scrapers and rotor must be replaced together.

If operators want to only replace the scrapers but use the old rotors, they will need to find a workshop with vertical lathe to machine the scrapers to ensure the equal gap between scrapers and basket. and make balancing for the whole unit.

The method of using flat washers to adjust the gap between screen and rotor may solve the problem of installation. But the gap between screen and rotor maybe not equal. Do balancing will be another challenging.

It is high speed rotating equipment. If the rotor assembly is not in balance. It will cause abnormal vibration, it may damage the machine, or even cause dangerous.

GN Solids Control makes vertical cuttings dryer to treat oil base mud cuttings discharged from shale shaker. The fine soil discharged from decanter centrifuge cannot be treated by vertical cuttings dryer. As the screen opening of vertical cuttings dryer is 0.25mm, 0.35mm and 0.5mm. But decanter centrifuge cut points is 2 ~ 5 microns. It is used to remove very fine solids. The screen opening is vertical cuttings dryer is too big to the decanter centrifuge soil.

GN Solids Control can offer full package vertical cuttings dryer together with electrical control panel, telescopic skid and Cantilever crane system for screens changing.
1) GN Solids Control equips an adjustable Cantilever crane with 0.5T Hand chain hoist for vertical cuttings dryer screen changing.
2) The vertical cuttings dryer skid designed by GN Solids Control can be adjustable to lower down for transportation, and it is also it’s easily Rotatable. GN Solids Control design vertical cuttings dryer skid is heavy duty. It is to make it more reliable and easy for operation. It is complete with walkway, handrails, stairs and connections between the vertical cuttings dryer and flush pump.
3) GN Solids Control can also equip a small vibration motor system under the vertical cuttings dryer skid to help for the solids discharge. Mostly GN Solids Control does not equip the vibrator motor system. As the solids discharged from vertical cuttings dryer is with very lower liquid, it is very dry, like powders. It is optional function. GN Solids Control can offer the vibrator motor system in case clients want it.
After the vertical cuttings dryer, GN Solids Control can offer high speed decanter centrifuge with telescopic skid or catch tank, and feeding pump for the centrifuge.

Furthermore, GN Solids Control can offer screw conveyer system under the solids control shale shakers to collect drilling cuttings and transfer to vertical cuttings dryer for separation. GN Solids Control can also offer screw conveyor auger system to transfer the dry cuttings discharged from the package.

The equipment and system used together with the drilling rig to clean and recycling drilling mud is caused as drilling fluids solids control equipment and solids control mud system. Its principle is liquid and solids separation.

During the drilling process, the dirty drilling fluid exits the wellbore through a flow line and be charging to the solids handling equipment for solids control. After removing the unqualified bigger size particles, the mud is cleaned and fed into the wellbore via the suction tank through high pressure mud pumps. The equipment is arranged in the right way to remove successively smaller particles during its processing.
A full function drilling fluids handling system will including below tank unit:

1) Firstly, there will be a trip tank section, it is an associated system for gauging pipe displacement during tripping operations. It is normally equipment with a small power trip pump, an mud agitator, and a small volume tank less than 10 cbm.

2) The shale shaker tank / separation tank section is the major part of the mud processing system. The tank(s) and associated relative equipment is used to remove useless solids and recovery useful drilling fluid from the handling process.

3) Discharge tank unit, the tank(s) or pit(s) and equipment located at the well site used to store and process drilling fluid and cuttings for disposal.

4) Reserve tank unit, the tank(s) or pit(s) and associated equipment used to isolate drilling fluid from the active system. The mud mixing system is normally equipment on/together with a reserve tank, and it is qualified to mixing to any of the clean mud tank compartment.

5) Suction tank unit, it is the tank(s) from which the high pressure mud pumps take suction, and any associated pumps or mixing equipment.

The popular solids control and handle equipment are as following:

1) Shale shaker is the most popular and widely used equipment for drilling fluids liquid and solids separation.

2) Mud cleaner, desander and desilter. They are the 2nd and the 3rd stage solids control equipment after shale shaker separation.

3) Decanter centrifuge is the 4th stage solids control equipment for barite recovery or fine solids separation to reduce the mud weight.

4) Degasser device (vacuum degasser or centrifugal degasser) is used after shale shaker but before hydra cyclone separation.

5) Jet mud mixing system is combined of mixing hopper and mixing pump. It is used to prepare qualified drilling fluids for the rig mud system.

500GPM is the most popular size mud recycling system for HDD (Horizontal Directional Drilling) rigs, water well drilling rigs and CBM (coal bed methane) machines. Every year, GN Solids Control will provide around 10 sets complete mud recycling systems to SINOPEC non-oil drilling divisions for their piping projects.

Many customers are interested in dual voltage equipment, they prefer dual voltage mud agitator, dual voltage shale shaker, dual voltage decanter centrifuge, dual voltage sand pump, dual voltage slurry pump. And dual voltage motor starters. In this case, they can use the same equipment for different power system project in case they need it.

Mostly in China the solids Control and drilling waste management equipment are designed for single voltage power system. As the dual voltage motor is not popular in China. Few companies can make dual voltage motors. It is hardly to find the reliable suppliers. There are some European and U.S brand offers dual voltages motors, but price is much higher. Normally, it is 2 or 3 times higher than the normal Chinese brand single voltage motors. It will be more cost effective for clients to buy another set of motors as backup.

decanter centrifuge and shale shaker 

If clients really want the equipment suit for dual voltage and suits for both 50hz and 60hz power system, GN Solids Control will recommend them to buy equipment per 60hz power system. In case they use the 60hz motor in 50hz power system, like for both 460V/60HZ and 380V/50HZ. The equipment rotating speed will be lower from 60hz to 50hz. Theoretically the lifetime of the 60hz motor running at 50hz will a little bit shorten the lifetime. But it will not shorten much. Compared with the big price margin on dual voltage motors, it is much more cost effective.

But the 50hz motor equipment is forbidden to use for 60hz system to avoid over speed and damage the equipment, or to cause dangerous.

For motor starter (electrical control panel), it is not problem to make it for dual voltage, like to suit for both 460V/60HZ and 380V/50HZ . The control panel will suit for both 50hz / 60hz. So you can use the agitator for 380V/50HZ. There will be a transformer on the control panel. And there will be a switch on the panel. Operators will shift the control between 50hz and 60hz by moving the switches.
