The equipment is based upon the highly successful Tri-Flo Mud Cleaning System for Directional Drilling and incorporates the following features:
Main Benefits:
• Cost effective method of re-cycling drilling muds.
• Reduces cost of supplying fresh mud.
• Avoids cost of disposing of liquid waste.
• Cut point of 16 micron removes particles which
damage triplex pumps, whilst leaving the useful
bentonite particles in suspension for re-use.
• The discharge from the cleaner is virtually dry,
dramatically reducing disposal costs.
• Reliable and durable design, based on 20 years of field experience worldwide.
• High speed continuous mixing facility incorporated.
Detailed process features:
Pre-screening of the returned mud using a
Tri-Flo 146 Shale Shaker.
This can handle a throughput of up to 520 USgpm and is designed to remove particles down to 178 microns. The "High G" elliptical shaker action produces a virtually dry product discharged from the top of the screen.
Secondary cleaning of the returned mud using a
Tri-Flo 8 x 4" Mud Cleaner.
The mud is pumped through a bank of eight Tri-Flo 4" Hydrocyclones where the larger particles are separated out by centrifugal force. The system is capable of a throughput of up to 520 USgpm and is designed to remove particles down to 16 microns. The larger particles are contained within a slurry which is passed over a Tri-Flo 126 shaker with a finer screen, which again produces a virtually dry product.
Integral mixing system using Jet Mixing Hopper.
This system allows fresh mud to be prepared very rapidly from bentonite powder. One of the three pumps is dedicated to this function allowing continuous mixing or recirculation as required.

Large capacity storage facility.
A total of 7000 US gallons is provided, with divisions providing a clean tank capacity of 4000 US gallons, a dirty tank capacity of 2000 US gallons and a mix tank capacity of 1000 US gallons. This provides the optimum balance for operation with most drilling operations.
Integral charge pump to supply clean mud back to the drilling rig.
This provides a continuous supply of clean mud under pressure to the high pressure mud pump, avoiding problems of starvation and cavitation which can rapidly cause damage.
