Shale shaker is the first stage solids separation and fluid cleaning equipment in the whole solids control system. It is widely used on drilling site. How many shale shakers do you need in a solids control system? How to make a decision?

Base the number of shakers required on the economics and physical constraints of the specific application. A “ballpark” estimate of shaker requirements, based on average drilling conditions can be made from the following table. This is a very rough estimate and should be used only as a guide.

The shale shaker is the only solids control device that makes a separation based on the physical size of the particle. The separation size is dictated by the opening sizes in the shaker screens. Hydrocyclones and centrifuges separate solids based on differences between their relative mass and the fluid. Shale shakers with linear vibratory motion are preferred for most applications because of their superior processing capacity and fine screening ability. Circular motion or unbalanced elliptical motion shakers are recommended as scalping shakers in cascading systems.

GN Solids Control manufacture over 250 units shale shakers every year. The GNZS594 model shale shaker is very popular around the world. Its screen is composite material and can be changeable with Mongoose screen. With linear vibratory motion, it’s performed perfectly in most applications.
