Tailored Mud Recycling Units for Diverse Drilling Operations: Compact and Efficient Solutions

Mud Recycling unit can be applied for many drilling operations. Big mud recycling unit is usually required for oil & gas drilling process; and we call it solids control system. Compact mud recycling unit is popular for HDD drilling, geothermal drilling, Core drilling, Piling, Tunnelling etc. For some limited operation space, we can provide bespoken mud recycling units to fit for the limited areas, smart operated for easy operation.

According to the requirement, we customized crawler truck mounted compact mud recycling unit for the client. The small mud tanks with light weight can be moved by small forklift to the underground mining roadway; the heavy units with centrifuges & high-pressure mud pumps equipped with crawler truck, can move forward or backward by remote control panel. The mud recycling units basically consist of 3 parts as follows:

Part 1: Dirty mud collection tank system:

There are 2 tanks in the mud collection system. The 2 tanks can work individually or can work together according to the return mud capacity from borehole. The tanks are equipped with level meter and the slurry pump to transfer the mud to the next stage can work automatically according to the sensors of level meter.

Part 2: Mud Recycling system:

The mud firstly separated by cyclones and screening to remove the bigger solids; and then treated by decanter centrifuge to remove the fine solids. The centrifuge is equipped with variable speed control drive, the bowl speed can be adjusted according to the performance of separation. The control cabinet is equipped with air conditioning for dehumidification.

Part 3: Mud mixing system with mud charging pump

After the mud cleaned in 2 ^nd stage, the “clean” mud will be transferred to the mud mixing tank, where the mud properties will be detected and adjusted. After the mud property can meet the drilling requirement, the mud will be charged to the drilling rig by high-pressure mud pump. It is a triple-cylinder mud pump.

The above mud recycling units can be adjusted to meet the coal slurry dewatering process.

1)      The coal slurry firstly can be introduced to a storage tank with mixing agitator

2)      And then the coal slurry can be fed to shaker screen to remove coarse solids

3)      After separation by screening, the slurry can be fed to centrifuge to remove fine solids

4)      After dewatering by centrifuge, the coal slurry can be dried to achieve the desired moisture level.
