Special performance of DCTLL-A vertical drilling cutting dryer

Vertical cutting dryer is a new design and product of drilling waste management system. DCTLL-A vertical drilling cutting dryer is a kind of separation equipment which utilizes mechanical rotary produce centrifugal force to realize.

vertical cutting dryer

Special performance of DCTLL-A vertical drilling cutting dryer:

1. Versatility and high performance

Drill cuttings are conveyed from the shakers to the VERTI-G cuttings dryer through a variety of site-engineered conveyance systems. Maintained by programmable logic control (PLC), the flow of cuttings into the VERTI-G dryer is continuously fed to yield optimal liquid/solids separation.

2. High-speed centrifuge for maximum in liquid/solid separation

The VERTI-G cuttings dryer incorporates a high-speed vertical centrifuge that achieves maximum liquid/solid separation in large-volume processing. This mechanism makes the VERTI-G dryer one of the industry’s best performing and most dependable cutting dryers. Available in both standard size and compact configuration.

3. Improved efficiency and lower costs

The VERTI-G cuttings dryer improves overall cost efficiency by recovering costly drilling fluid that is recovered from cuttings, as well as whole mud lost from shaker failure and rig motion. Further, the VERTI-G cuttings dryer produces lower waste volumes by generating dryer solids in both oil- and synthetic-base drilling fluid systems. Reducing waste volume helps to dramatically reduce disposal costs.

Customized DC diesel tank shipped to Poland

DC Company finished the production of diesel tank for Poland clients and prepared to delivery to XinGang Port.

Oil tank is the major corollary equipment in oilfield drilling rig, it is mainly used to store and provide fuel to generator set. The oil tank designed and produced by our company is easy and convenient to use and maintain.

oil tank

This time we manufactured the oil tank strictly accord to users request, including wall thickness, paint standard and American steel. We test many times after finish the production, to avoid any nonconformity points.

DC Oil tanks have been exported to over 60 countries and area with their good quality solid control equipment/ waste management equipment, countries like America, Brazil, Chile, Venezuala, Kuwait, Iran, Iraq, Saudi Arabia, Oman, Israel, Australia, New Zealand, Mongolia etc.

Typical areas of use of decanter centrifuges

The decanter centrifuge produced by DC Machinery are horizontally positioned centrifuges with a solid wall drum (therefore also called solid wall screw centrifuges). The drum is cylindrical-conical, it consists of a longer cylindrical part (the so-called clarifying zone) and of a conical part (the so-called dry zone). The material to be processed is fed via a so-called feed tube into the drum, where, due to the centrifugal force the solid material particles sediment on the drum wall.

Decanters (decanter centrifuges) are “solid material oriented” centrifuges which can process liquids / suspensions with high solid material contents (up to ca. 60% by volume).

Typical areas of use are:

Clarification of liquids and suspensions
Thickening of sludges
Dehydration of sludges and suspensions
Classification (wet classification of solid materials in a suspension according to grain size)
Separation of 3-phase mixtures (two fluid phases, insoluble in each other, and a solid material phase) etc.

The optimization of mud gas separators from DC Solid control

DC Mud gas separator offers the highest gas-and liquid handing capacity available. Its highly efficient baffling system maximizes mud gas separation, enabling operators to drill deeper, large-diameter wells and exploratory wells at higher circulating rates while safely handling greater volumes of gas. It also minimizes mist carry over and gas-cut mud at the flow line.

mud gas separator

Main features of mud gas separators manufactured by DC Solid control :

1. Main body diameter are 600, 800, 1000 and 1200mm which can allows the highest gas- and liquid handling capacity available.
2. Optomizes safety and control. The mud gas separator unit enhances safe drilling practices during underbalanced conditions, improves” kick” handling capabilities, permits optimum circulation rates and large-diameter holes to the drilled through the targeted zone.
3. High efficiency baffle system. Maximizes mud gas separation, minimizas mist carryover which produces a cleaner flare and minimizes gas-cut mud at the flow line.
4. Capable pressured operation. Increases gas-and liquid handling capacities and permits immediate sale of gas during drilling operations.

DC use high quality steel materials manufacturing normal pressure prevent H2S Mud Gas Separator,can effectively prevent the harmful gas erosion, ensure the man- machine safety production.

DCQJ250x2/100×10 Mud cleaner is one of the most hot sale model of mud cleaner equipment whose flow is about 240m3/h. At present DC Solid control has a finished mud cleaner at a big discount sale can meet your urgently requirements.


DC Mud Cleaner completes consist of everything you need to plumb up to and operate the equipment as it own stand alone unit. Just select the Mud Cleaner and Shaker combination you need based off of the flow rate you need to process and what micron level you need to cut to.

The unique manifold design minimizes the pressure drop across the hydrocyclones, thereby maximising solids removal and reducing the volume of mud discharged with the captured solids from the cone.

If you need to retain a larger capacity we are more than capable of constructing and fitting the equipment on any size mud cleaner you need.

DC Solid control provides perfect mud system for different users

Mud system, basically drilling mud tank system, is a combination solids control equipment that is connected among mud flow lines configured on mud tanks. It aims to clean, recycle, mix and condition the drilling fluids in desired properties as per the drilling formation requirements.
