The shale shaker is the first stage of solids control equipment in drilling purifi-cation system. It can remove cuttings above 75μm brought from the drilling well to leave the liquid with smaller particles into the tanks below, which will flow into next grade solids control equipment to be treated. KOSUN linear motion shale shaker is especially effective while drilling top-hole sections where heavy and high-volume solids are usually encountered. In these intervals, shakers may generate powerful G-forces and its effective vibrating motion can quickly remove the dense solids from screens and particles from wells.
Secend stage solids control equipment – Desander In the 2nd stage of solids control for drilling fluids, desander makes separations between 45 and 75 μm. Characteristics of desander by Kosun:1. Polyurethane ( PU ) material or high-chromium cast iron to make desander cones for longer lifespan. 2. Clamp type for easy maintenance.3. Compact design with small footprint. 4. Flexible options for 1, 2 or 3 pieces of 10″ or 12″ cones for different capacities. 5. Flexible fast connection are available for user assembly.
Third stage solids control equipment– Desilter In the 3rd stage of solids control for drilling mud, the desilter by Kosun makes separations between 15 and 45 μm. Characteristics of desilter by Kosun: 1. 100% Polyurethane ( PU ) material to make desilter cones for longer lifespan. 2. Clamp type for easy maintenance. 3. Compact design with small footprint. 4. Flexible options for 8, 10, 12, 16 or 20 pieces of 4″ or 5″ cones for different capacities. 5. Flexible fast connection is available for user assembly.

Shale shaker for solids control are devices that remove drill cuttings from the drilling fluid while circulating and drilling. There are many different designs and research into the best design is constantly ongoing since solids control is vital in keeping down costs associated with the drilling fluid.
The basic design consists of large, flat sheets of wire mesh screens or sieves of various mesh sizes that shakes or vibrates the drill cuttings, commonly shale shaker, across and off of the screens as the drilling fluid flows through them and back into the drilling fluids processing system, often called a mud system. This separates the drill cuttings, often called solids, from the drilling fluid so that it can be recirculated back down the well bore. In oilfield industry,linear motion shale shakerare widely used for drilling mud solids cotrol of oil gas well drilling for rig.
KOSUN Linear Motion Shale Shaker is especially effective while drilling top-hole sections where heavy and high-volume solids are usually encountered. In these intervals, shakers may generate powerful G-forces and its effective vibrating motion can quickly remove the dense solids from screens and particles from wells.
KOSUN Linear Motion Shale Shaker are ideal for high-capacity processing and the compact and easy-to-service design makes them a perfect choice for fast conveyance and heavy loading in tough drilling conditions. When drilling top-hole sections or while heavy-volume solids are encountered, in these intervals, shakers are required to generate high G-forces to effectively move high-capacity drilled solids across the screens.
Solids control is a technique used in the drilling rigs to separate the solids crushed by the drill bits that are brought to the well surface. When unwanted solids are efficiently removed from the circulation system, the fluids in the wells are of highest quality. Efficient Solids Control results into less replacement of fluids, less waste and few additives that are needed to be removed and disposed. This also significantly decreases the risk of downhole related problems due to excessive solid contents in the drilling fluid.
Normally, solids control system contains five stages: the mud tank, shale shaker, vacuum degasser, desander, desilter, and centrifuge. The shale shaker is used to separate big solids with diameter above 75μm, the desander addresses solids from 45-74μm, and the desilter segregates solids between 15-44μm. Sometimes the desander and desilter are combined as one high efficiency mud cleaner. When air enters the drilling fluids, a vacuum degasser is used to separate the air. When there is no air in the mud, the degasser works as a big agitator. All these stages are mounted on the top of the mud tank. After separating the solids, the clean mud can be pumped into the borehole again.
Recent advances in solids control include the creation of a closed loop system which allows for increased environmental control and reduction in the potential for spills of drilling fluids. Several US states have either passed or are considering the implementation of closed loop systems, particularly for hydro-fracturing operations.
