Mud recycling plant uses screens to direct, separate, and control drilling fluid flow in the process. The heart of Mud recycling system is the shale shaker. This vital piece of equipment filters out the gritty pieces of the Barnett Shale from the drilling fluid (or &#;mud&#;), so that the fluid can recirculate and thus continue the recycling process. The two main purposes for screening the mud recycling plant are to remove oversize material from the shaker or undersize solids from the mud recycling plant and completely size the solids produced. a mud recycling plant must perform both functions.

The feed may contain mud solids that does not have to be crushed and which should be removed from the input to the primary crusher. A scalping shaker is frequently used between the feeder and the primary crusher to remove from the feed material that is smaller than the setting of the crusher. It may be a grid, grate, or screen, and it may be stationary or it may vibrate. Solids removed from the feed is directed to finish screens and reduction crusher.
The grizzly is the most commonly used scalping shaker. It consists of evenly spaced. Parallel, tapered, and inclined bars running in the direction of the feed to the crusher. Undersize material (solids) in the feed drops through the bars and oversize material is stored on the bars and discharged at the end of the grizzly. Therefore, the spacing of the bars is determined by the desired size of feed.
Screens are made of perforated steel plates or wave wires which form a mesh of square or rectangular openings between adjacent screen material. The three basic types of screens used for mud recycling processing are known as:
Mud recycling plant normally uses horizontal screen to remove and recycle materials. The horizontal screen is a modern vision of the shaker screen for improved effectiveness caused by higher speed motion and a shorter stroke. It is similar to the inclined vibrating screen but it requires less headroom. Since it is held in a horizontal position, this screen is not used for scalping.
Operators must think about how to protect their investment beyond purchasing durable screens. Proper maintenance will affect all screens&#; quality. On the job site, screens should be kept in their boxes and stacked flat (or in accordance with the manufacturer&#;s recommendations). Mishandling panels, especially during storage and installation, may cause premature screen failure. Operators should also ensure that screens are always properly mounted, check for proper tensioning and replace worn deck and crown (channel) rubbers as soon as possible. Personnel should never walk on screens when working on shakers. They should also avoid dropping tools on screens. After service each day, screens should be washed down, especially if drilling is occurring in sticky solids such as clay. Periodically, screens should be carefully inspected for tears and holes. If unresolved, these issues will lead to a major mud weight problem and may cause a heavy buildup of solids being returned to the active mud tank. Monitoring for extremely high mud weights will also help extend screen life. All personnel must be cognizant of the proper operation, installation, storage and maintenance of shaker screens.
Shale shaker is a general term for a vibrating device used to screen solids from a circulating drilling fluid.
Shale shakers are the most important and easiest-to-use solids-removal equipment. They are the first line of defense once drilling fluid is returned from the well bore. In most cases, they are highly cost-effective. If shale shakers are used with torn screens, fluid bypassing screens, incorrectly sized screen panels, or worn parts, the remaining solids-removal equipment will not perform properly.
The primary purpose of a shale shaker is to remove as many drilled solids as possible without removing excessive amounts of drilling fluid.
These dual objectives require that cuttings (or drilled solids) convey off the screen while simultaneously most of the drilling fluid is separated
and removed from the cuttings. Frequently, the only stated objective of a shale shaker is to remove the maximum quantity of drilled solids.
Stopping a shale shaker is the simplest way to remove the largest quantity of drilled solids. Of course, this will also remove most of the drilling
fluid. When disregarding the need to conserve as much drilling fluid as possible, the ultimate objective of reducing drilling costs is defeated.

API Number: the sieve equivalent as per API RP 13C
Conductance: the ease with which a liquid can flow through the screen, with larger values representing higher volume handling
Microns: a unit of length equal to one-thousandth of a millimeter
Non-blanked area: an evaluation of the surface area available for liquid transmission through the screen
We offer high quality products at competitive price.
Timely after-sale service.Shortest delivery time.Flexible payment terms.
Most of our equipment can be replaceable with international brands.
For the shaker motors, we use famous brand Oli or Martin. Some clients request a higher configuration level. Then the motors will be Ital-Vibras imported from Italy. High-quality motors will help much on stable performance and good result.
The deck angle can be adjusted easily by just screw the nut on the jackscrew. And angle should be adjusted according to actual working conditions. For example, when we need a high flow rate we need to make a deck with a small minus angle or in parallel to the ground. If we need better filtration or more dry solids, please make a deck with an uphill angle. The rotation can be clockwise or anti-clockwise
