SD 250 mud system for tunneling drilling
Aug 14

GN have designed and manufactured SD 250 mud system for tunneling drilling according to clients requirements. It can adapt with tunneling drilling cycling system. Its handling capacity can reach up 250m3/h.

This system is composed of 3 classes solids control stages. The first stage consists of two GNZS83-3BF shale shaker for screening; the second and third stage consist of 1 set ZQJ300×2/100×12 mud cleaner and 2 sand pumps. The main working principle is using sand pump to supply sufficient power for the cyclone, then the drilling mud can enter the cyclone for centrifugal separating. The drilling mud has been refined.

Mani Function of SD 250 mud system for tunneling drilling

1、The SD 250 mud system for tunneling drilling is composed of 3 classes solids control stages: a. shale shaker separation; b. desander cyclone separation; c. desilter cyclone separation. All particles above 1.0mm in mud can be separated be this system.

2、The matched screens of GNZS83-3BF shale shaker 1100×830, 3 pieces stainless aperture screens with 5mm aperture. The matched screens of ZQJ300×2/100×12 mud cleaner is 1100×830,10 -60 mesh stainless pyramid screen.

3、 the design capacity: ≤ 300 m3 / h, Rated capacity: 250 m3 / h.
Adaptable environment: -15 ° ~ 50 °.
4、 adaptable mud viscosity: ≤ 80 S.
