23RPM 28RPM Pulley Adjustable Centrifuge Mud Purification Drilling Centrifuge
Pulley-Adjustable Centrifuge: 23/28 RPM Differential for Mud Purification
The LW630×1260-N power frequency centrifuge delivers efficient removal of 2–5µm fine solids and 6–10µm harmful phases in conventional drilling operations. With dual drum speed options (1,400 or 1,600 RPM) adjustable via pulley configuration, it generates centrifugal forces up to 967 Fr, ensuring optimal separation without complex controls. The 55kW main motor supports 80 m³/h throughput while minimizing barite loss. Dimensions: 3520×1880×1800 mm; weight: 4,800 kg.Engineered for cost efficiency, this centrifuge uses fixed-speed motors and mechanical pulleys instead of VFD systems. Operators switch between 1,400 RPM (740 Fr) and 1,600 RPM (967 Fr) by adjusting drive pulleys—ideal for stable mud density conditions. Reduces upfront costs by 25% and energy consumption by 15% compared to variable-frequency models.
Features
Constant Drum Speed - Can be changed by changing the drive pulley.
Easy to Operate and Maintain- Can be matched with different drum speeds and processing capacities according to the size of the drilling rig and actual demand.
Cost-saving - The centrifuge of choice for conventional drilling mud treatment.
