The relation between shaker screen mesh and the hole diameter

A shale shaker screen is a vulnerable spare part of a shale shaker. But the shaker screen is very important in the drilling mud recycling system. The shaker screens design and quality determined the separation performance of the shale shaker. Generally speaking, the working environment and the drilling mud contents are the most determining factors to choose a suitable MI-SWACO shaker screen. The other factor is the size of the particle in the drilling mud fluid to be separated. If you know the particle size, so the shaker screen mesh is determined.






What is the shaker screen mesh?


Shaker screen mesh refers to the quantity of holes per square inch. So the Derrick shaker screen mesh has an inverse proportional relation with the hole quantity. That is to say, the larger the shaker screen mesh, the smaller the screen hole size. Commonly speaking, the relation between them is: Mesh x Hole Diameter(micron)=15000


For example, if the shaker screen mesh is 200, then we can estimate that the screen hole diameter is about 75 microns. This is very useful for us to choose the proper shale shaker screen according to the mud fluid contents.


Other shaker screens or you can say shale shaker screens too, are a type of mechanical screen, aim to take solids out or separate solids from drilling fluid (mud). Usually, a composite frame shaker screen is made of stainless steel, polyurethane or composite frame. It is a spare part of a shale shaker and a combined shaker frame by stainless screw and wedge block.


Shale shaker spring is a component that provides a damping effect. The spring quality and feature will help us to get a better process when stopping the shaker. Most of the springs are made of high-quality special spring steel. However, some of the springs or we call it float amount/absorber is made of rubber or combined rubber and steel.






In minerals processing, one of the most important hydrocyclone applications is within closed circuit grinding operations, classifying particles leaving the mill. Incorrect particle classification has a detrimental impact on plant efficiency and can unnecessarily consume circuit capacity.


Feed pellet machines can bring benefits to your poultry farming. Choosing a suitable feed pelletizer machine and using it properly will significantly improve the quality of the feed. It will soon reflect a benign effect in the production process. If you can further master the technology of making animal feed pellets, you can also greatly reduce the cost of materials, thereby increasing profits.






It is agreed upon in the trucking industry that ratchet straps are the most secure way to tie down a heavy load, providing the most strength and security for oversized gear! The best heavy-duty ratchet straps wrap, hook, or clip to your trailer rub rail or D-rings. These tie-down straps tighten using a ratcheting system so you can apply the right amount of pressure over or around your cargo to ensure it will stay firmly in place. Having reliable, high-quality ratchet straps is integral to making sure you deliver your cargo safely and securely!






Are you planning your next overhead lifting project and unsure about the best type of industrial lifing sling to use? Or, maybe you are not getting the service life you would expect out of the slings that you’re currently using? Alloy chain slings, wire rope slings, synthetic slings, and metal mesh slings can all be used to safely and efficiently lift, move, and position a load.


But, choosing the right type of lifting sling is dependent on a complete understanding of the application, the environment it is being used in, and how the sling will be used to support and lift the load. Wire rope is a preferred lifting device for many reasons. Its unique design consists of multiple steel wires that form individual strands laid in a helical pattern around a fiber or steel core. This structure provides strength, flexibility, and the ability to handle bending stresses.






Regardless of the time spent on a roof, the risk of falling is high. Any fall is likely to result in a serious injury. Industrial rope and nets installed below a high-level work area reduce the distance that a worker can fall. They absorb the impact of the fall and provide a soft landing to reduce the likelihood of a person being injured. Safety nets are collective fall arrest systems, not fall restraint systems. That is, they provide passive protection from falls while allowing people to work at height without restricting their movement. A safety rope passes through each mesh around the perimeter of the net and determines the net's overall dimensions.
