The VERTICAL CUTTING DRYER is used for the reduction and recycling of drilling waste to reduce the operator’s drilling fluid cost. The dryer is a continuous screen-type vertical centrifuge, which can automatically control the feed and is used for solid-liquid separation. The dryer is used to recover liquid phase drilling fluid from drilling cuttings. By applying high centrifugal acceleration force to drilling cuttings, the effect of separating the liquid phase from drilling cuttings is improved. The expensive liquid phase in the mud system is recovered through further purification treatment. For diesel oil, mineral oil, and synthetic oil base mud, it can work well. Because it is easier to separate oil from large drilling cuttings, it is more effective for the synthesis of oil-based mud. Synthetic oil-based mud systems also have a higher mud value, making the machine more attractive from an economic point of view. In addition, the system reduces the amount of waste and disposal costs incurred on the rig site.
The Vertical Cuttings Dryer working principle:
Feed is fed from the top of the machine via a feed funnel, accelerated to machine speed by thrusters and scrapers, and sent to the screen surface. When the feed touches the screen surface, solid-liquid separation begins immediately. The flow rate on the screen is controlled by the speed difference between the propeller and the screen, as well as by the scraper blades, which stir and flip the solid phase at the same time, further facilitating separation. The solid phase is discharged at the bottom of the screen and falls into the discharge zone of the machine under the action of gravity. The solid phase is then collected through a funnel or other conveyor system placed under the machine. The liquid phase falls into the flow path through the screen and is discharged through the liquid phase outlet.
Cuttings dryers are designed and manufactured to work safer. For maximum safety, this large high-speed rotating machine requires maintenance and maintenance. Unsafe practices in maintenance and operation can endanger people and property.
