Horizontal Drilling Waste Management Equipment Auger Screw Conveyor

APLS series screw conveyor used in drilling waste management transfer at drilling rig site

Screw conveyors are also referred to as Auger feeders. The feeder assembly consists of a motor, gearbox, and screw conveyor. The conveyor shape is similar to the centrifuge conveyor. Impellers welded together and/or on the central shaft. The conveyor is driven by a motor rotating at a certain speed. For example, some rotate 20 rpm, some turn 60 rpm. Different material and working conditions request different rotation speeds.

So, the screw conveyors can be designed as VFD. That means the motor and the control panel can realize variable frequency during auger operation. We can adjust the auger feeder according to practical condition. Most of the auger feeders are used along with drilling mud solids control system. This will help users to get them disposed of solids or waste transferred in time. And under the transfer of auger feeder, the drilling fluids or waste is easy to handle for further process.

APLS series screw conveyor features

• The machine can be made as to any length, The machine material can be made as stainless steel 304 or carbon steel or high-temperature steel.
• the screw can be made with shaft or shaftless.
• High power, low energy consumption, and beautiful appearance.
• It has a strong conveying capacity, stable transportation, uniform material feeding and difficult material feeding.
• good maintenance, easy maintenance, low failure rate.
• The dust is not easy to leak when the powder is transported, and the upper cover is sealed.
• the conveyor is widely used.
• The blade can be made as a whole, not weld.

The screw conveyor must be equipped with the cover. Some of the covers are plate or sheet connected with folding pin and mounted by bolts. Some covers are steel grating to help better observation and safe operation to avoid any people injury. Furthermore, the cover can be joint with the emergency stop switch to avoid any accident during auger feeders running. 

Screw conveyors are usually fed by disposed of solids or waste from the solids control, and some sludge material to be processed. From a concentrated place to the feeders. Then the feeders can transfer materials to cuttings dryer, to other tanks or places for further handling. Auger feeder can transfer a mixture of solid and fluid, can transfer solid. Different feeders' size and length decide the handling capacity.

Furthermore, the rotation speed is another issue affecting the capacity of the feeder. If auger feeders were designed with the same diameter and length, more swift conveys leads to higher efficiency. That means in unit time the transfer quantity much larger. But of course, based on the rated and permitted handling rate under certain motor and mechanical design

The screw conveyors can be used in drilling waste management, as well as the oil sludge treatment. No matter the onshore or offshore platform, the auger feeders will provide a convenient and effective transfer. Please find below specification for your reference

Yes. There are many options on the auger feeder configuration. Such as motor power, gearbox reduction ratio, the conveyor length, the shaft included in or not. The control panel and the electrical system, the colors, and so on. Please feel free to contact AIPU get your feeders solutions
