1. In order to ensure the stability of the performance and the reliability of mud recycling systems for the coalbed methane drilling rig, the requirements for the linear shale shaker, desander, decanter centrifuge, sand pump, jet mixing device, agitator, and mud for the design, manufacture, inspection, supply and transportation protection are as follows.

2. The slurry preparation, screening, circulation, purification and control of the mud recycling system should proceed smoothly. In addition to the requirements of roads, railways, shipping and short-distance at the site, the system design should be based on humanized operation to ensure that the staff save time, effort and worry during the operation process.
3. Ensure that the manufacturer has all the design, manufacture, supply, quality inspection and testing of mud recycling system such as linear vibrating screen, desander, centrifuge, sand pump, jet mixing device, agitator, mud gun, submerged slurry pump, etc. ability..
4. It is necessary to ensure the performance requirements of the provided mud recycling system for the provided coal bed methane drilling rig, and all equipment are matched with each other reasonably.

5. When the mud viscosity is less than or equal to 45S-1, the mesh number of the shale shaker can reach 100/20 meshes. Generally, the screen meshes are 40/20-60/20 meshes.
6. The screen mesh of the desander can reach 120.
7. The solids control system can handle solid particles larger than 15μm in the mud.
8. The solids control system can work continuously and normally under the rated power.
9. The equipment noise complies with the national environmental protection standards, and the distance from the sound source of the equipment is ≤85 decibels.
