The mud recycling unit is used for directional drilling rigs to handle mud in the construction of directional drilling rig. The selection of mud recycling unit generally follows certain principles. This article will share 4 principles of mud recycling unit configuration, and how to choose a mud recycling unit for directional drilling? 

Mud recycling unit types and specifications

Although the mud recycling unit is non-standard equipment, there are still some mature system schemes, and it is necessary to understand the specifications of the conventional mud recycling unit. Take the type of mud recycling unit of the BWHDD series of Brightway as an example, specifically including: 200GPM type (45m/h), 250GPM type (60m/h), 350GPM type (80m/h), 400GPM type (90m/h), 500GPM Type (120m/h), 1000GPM type (240m/h), 1500GPM type (360m/h), etc. 

Selection principle of mud recycling units

 The configuration principle of the mud recycling units is mainly based on the tonnage of the drilling rig and the processing capacity of the mud pump at the construction site of the directional drilling rig. Of course, the need for special circumstances of on-site construction is not ruled out. Understand 4 points and you will understand how to choose a directional drilling mud recycling unit.

 1. The 1000GPM (240m/h) mud recycling unit is mainly adapted to a mud pump with a flow rate of 4000L/min and an HDD non-excavation directional drilling rig with a return force of 500-800 tons. The mud recycling unit is designed to handle 240m/h.

 2. The 500GPM (120m/h) mud recycling unit is mainly adapted to mud pumps with a processing capacity of 2000-2500L/min and HDD non-excavation directional drilling rigs with a return force of 250-350 tons. The designed processing capacity of the mud recycling unit is 120m/h.

 3. The 350GPM (80m/h) mud recycling unit is mainly adapted to mud pumps with a flow rate of 1200-1500L/min and HDD non-excavation directional drilling rigs with a pullback force of 60-200 tons. The designed processing capacity of the mud recycling unit is 80m/h.

 4. The 200GPM (45m/h) mud recycling unit is mainly adapted to 400-800L/min mud pumps and 80-160 tons HDD directional drilling rig rigs. The mud recycling unit is designed to handle 45m/h.
