Air Knife feather in vertical cutter dryer

The purpose of vertical cutting dryer is help oil rig to meet and excess the current and upcoming environmental regulation and control the operation cost effectively.  Separate the solids contents in the drilling fluid will maximum the life use of drilling fluid yet the solids remove drilling fluid need to be properly process so it will not contaminate the earth soil by removing moisture as much as possible.  The vertical cutting dryer working concept is similar like garment washer in high speed spinning mode.  The inside of the vertical cutting dryer contain the screens to filter the solids.  Yet in continues high speed spinning usage, the screen often get clogged and need to stop during the process.  To encounter this issue, GN Solids Control’s vertical cutting dryer feather air knife inside the dryer to prevent clogging the screen.

Air knife is a high compress air system blow off liquid and debris wile object that need to be process in continuous moving motion.  The “knife” produce uniform sheet of laminar airflow pressurized air containing a series of holes or continuous slots through which pressurized air exits in a laminar flow pattern.  This impact of air can be from mist breeze to high velocity without making contact with object.

Air knives remove liquids, control the dense of liquids, dry the liquid covering, remove solids particles, cooling the surfaces or create a press force to assist in the mechanical bonding of materials to the surface. Electrical currents from anti-static bars can also be injected into the exit air knife stream to eliminate the static electricity charge on some surfaces.

The most common use of air knives is to contain or remove flowing materials (liquids or solids) from the surface of material. The applications include drying solids to prevent solids stick on the screen.   They can also different temperature air to a surface, or create an invisible air barrier to separate heated or cooled environments.

GN Diamond Drilling Decanter Centrifuge for South America and North America

Along with rising requirement of small decanter centrifuge, we exported many decanter centrifuges to diamond drilling industry. Our decanter is the core equipment in the whole dewatering system. Recently, we have sold three sets of those decanter centrifuges including two for Canada diamond drilling company and one for Chile diamond drilling company. There are rich metal, mineral and coal deposited in the deep ground. Many diamond drilling company should utilized a decanter centrifuge or a dewatering system assisting drilling rig in order to explore the mineral. Our diamond drilling decanter centrifuges have been tested in the field and recognized by many diamond drilling company

 

First and foremost, we utilized the high standard stainless steel material to fabricate the equipment coping with harsh mud condition. In order to reach high 3800 rotating speed, we carefully make the dynamic balance and relative inspection before delivery to the customer’s jobsite. Therefore, customers are satisfied with our decanter centrifuge working performance and separation result. Large amount of solids wear out solids discharge port so we install the replaceable solids discharge port for convenient and fast replacement.

 

Secondly, we offer both centrifuge with motor and control panel and centrifuge without motor and control panel to customer. Especially in Canada, they prefer to CSA standard explosion proof motor and control panel. So they are willing to install their local motor and control panel. And we accept the customer’s requirement and give centrifuge without the motor and control panel

 

Except the small diamond drilling centrifuge, we also provides regular 14 inch, 18 inch and large 22 inch bowl decanter centrifuge for solids control system and dewatering system in North and South American. As a rising solids control star, GN quickly enters the international solids control market relying on our advanced technology and quick response after sale service. GN decanter centrifuges are dispatched to all over the world drilling jobsite.
