What are the technological characteristics of the drilling fluid Shale Shaker

Drilling fluid Shale Shaker is an important equipment in the solids control system. Its performance directly affects the control effect of the entire solids control system. Therefore, our on-site operators need to understand the process characteristics of the Shale Shaker. Then the drilling fluid Shale Shaker What are the characteristics of the process?

The earliest sector using Shale Shaker is the coal industry. It is mainly used for classification, dewatering and recovery of useful media. Because drilling fluid Shale Shaker have their own holding points, it is impossible to copy existing mine Shale Shaker. 

The main features of the drilling fluid Shale Shaker are:

1. The medium sieved by the drilling fluid Shale Shaker is liquid, and the waste is solid particles.

2. The drilling fluid sieved to it is a mixture of liquid phase, solid phase and chemical treatment agent with great changes in physical and chemical properties.

3. The separated solid particles (mainly cuttings) have a particle size ranging from a few microns to more than 20 millimeters. Since the finer the sieve is required, the maximum number of meshes used by the screen has reached 325 meshes, and it is rare to use coarse screens below 40 mesh.

4. Due to the characteristics of the drilling industry, the drilling fluid Shale Shaker is required to have excellent transportability, simple installation, convenient screen replacement, extensive operation, reliable work, and few wearing parts.

5. The screening process of drilling cuttings on the screen surface is far more complicated than that of dry particles. The solid particle position on the screen surface of the drilling fluid Shale Shaker is very small compared with the mine screen, and it can not even form a material layer. In this case, the solid-phase particles are screened according to the size of the screen when the screen surface is vibrated.

The particles smaller than the screen hole continue to pass through the screen when moving along the length of the screen, and the surface of the material is larger than the screen hole. The particles are discharged in the direction of the screen surface. Generally, the covering length of the drilling fluid on the screen surface is generally two-thirds of the screen length.

On the part of the screen surface covered by the drilling fluid, the solid particles smaller than the sieve hole pass through the sieve hole together with the drilling fluid during the vibration process. In general, the maximum particle size of the undersieve of dry particles (coal, ore, etc.) has the following relationship with the size of the sieve: For a square sieve, the side length a of the sieve is 1.1-1.13 times the maximum particle size d of the undersieve , For a rectangular hole, the short side a= 0.7 – 0.8d.
