Vacuum Shale Shaker

ViST is Vacuum Shale Shaker Technology is the primary solids control equipment to reduce drilling waste and recycle drilling fluids.

The ViST Pan is installed under the last screen or mounted externally. And a suction hose is connected to ViST vacuum unit. The compressed air from air compressor or the rig air supply is required to create suction on the last screen surface, pulling additional fluid off the cuttings. It can reduce the liquid on the cuttings by 30-50%.

The negative pressure vibrating screen is a solid-liquid separation equipment that combines vibration screening with negative pressure suction technology. Through the dual effects of "vibration + vacuum adsorption", it significantly improves screening efficiency and reduces the liquid content of the discharge. It is widely used in many industries such as petroleum, chemical, mining, and food.

Advantages of vacuum shale shaker

1.Purification treatment of OBM, WBM and SBM;

2.It can be applied to land and offshore drilling rigs to improve the working efficiency of the vibrating screen of solids control equipment, recover drilling fluid and reduce the amount of waste.

3.It can replace the processing of drill cuttings drying screen, but at a lower cost.

4.Almost no additional floor space is required, meeting the space requirements of offshore platforms.

5.Tianrui can not only provide new vibrating screens equipped with ViST vacuum screen devices, but also install negative pressure screen devices on customers' existing vibrating screens. The installation is simple and quick.

6.By matching the ViST vacuum negative pressure vibrating screen, the solids control vibrating screen can be installed with a higher mesh size screen without pulp leakage, thereby improving the separation efficiency of the solids control equipment.

7.By discharging drier drill cuttings, drilling waste transportation and disposal costs can be reduced.
