Shearing mixing hopper and jet Mud Mixing System for drilling mud system

Jet mud mixing system is a normal and necessary part of most kind of drilling mud systems and liquid mud plant (LMP). It is used to prepare new mud and qualified mud, and service for drilling activities. The mud mixing system can be used to mix oil based mud (OBM), water based mud (WBM), as well as synthetic based mud (SBM).

Jet mud mixing system is actually a combination of mixing pump, mixing hopper and control panel. All of them connected by pipelines, they can be mounted on the tank separately per tank layout. They can also be mounted on the same skid as a complete unit.


The jet mixing hopper is also called shearing hopper. It can be mounted on different position of the mud cleaning system for different purpose.

Centrifugal pump is the most popular pump model for jet mud mixing system. Another pump model is shearing hopper. Clients can choose motor drive mixing pump, or diesel engine drive mixing pump, to meet for different demands.

Different position of jet mixing hopper for mixing system

1) The jet mixing hopper can be mounted on the top of the mud tank. Advantage of the tank top hopper is easy for mixing chemical as the gravity. But you should to consider lifting of the chemicals. Sometimes, it is even 1 ton big bag. you should consider the necessary device to help for the chemical lifting. Operation table and crane cradle is the popular way to service for it.

2) The normal way is to put the shearing mixing hopper on the tank skid, next to centrifugal mixing pump. The mixing performance may not as good as on the tank top, but also acceptable. And it is easier for the chemical lifting.

3) Another way for the shearing hopper is on a separate skid with centrifugal mixing pump and control system. The complete is in a separate skid. It is more flexible for application. Users is easy to more the mixing unit from one jobsite to another jobsite, or move it from one tank for another.


Mud recycling system with decanter centrifuge for HDD

GN solids control new designed mud recycling system with decanter centrifuge has been used for HDD mud recovery. Normally the client did not use decanter centrifuge, but for some special projects, the solids size are very fine, the 4 inch desilter cones are not enough, they have to use the decanter centrifuge to separate the fine solids. CPP, short for China Petroleum Pipeline Bureau, is the China largest Horizontal Directional Drilling Contractor, they have bought over 30 sets of muf recycling system from GN solids control in the past 5 years. Some of their mud recycling systems are tradional design with only shale shaker, desander, desilter 3 phase cleaning , some are with decanter centrifuge because of high percentage of fine solids in the drilling fluids.

This time they bought 4 sets of 1000gpm Mud Recycling System with GNLW452 middle speed decanter centrifuge, which is one of the most reliable working, high treating capacity with separation point 5 microns.

1000 gpm mud recycling system

The main features of the 4 sets of mud recycling systems are the equipments are installed in a 20ft standard container frame, and the mud tank size is replaceable with standard 20ft container, during working, they are installed with screws. And during transportation from one place to another, they will be shipped by the vehicle fit for 20ft container size. This is for fast move, fast disassembly, fast installation purpose.

Not only for the mud recycling system, we can also adopt such design into drilling waste management system design for the same reason. In some cold temperature area, you can cover some tarpaulin outside the 20ft steel frame to keep them warm in winter, so you can save the money of heating lines to keep them warm and fluxible.

If you need a similar design for your HDD,CBM, underground construction, mining project, pls contact GN sales.

Mud Recycling System for HDD Rigs

Generally, trenched will be excavated for pipe laying or conduits and cables installing. While, in some case that trenching is not practical for geographic factors or environmental reasons, directional boring, usually known as horizontal directional drilling(shortened as HDD) will be applied. HDD is a typical example of trenchless technology which means using a surface-launched Drilling Waste Management to bore a path for installing infrastructure such as pipelines, gas lines, oil line, sewer lines, water lines, power cable conduits, and telecommunication. HDD is normally applied when a river, road, landscape, or a congested place needs to cross for pipe and cable laying. Until now, installation length by HDD has been up to 2000 meters, and diameters up to 1200 mm have been finished in short length. Yet, that does not necessarily mean that HDD can be adopted for all road-cross or river -cross drilling. Actually, solids rock or sedimentary rock is the most suitable material. HDD is used instead of other techniques mainly for the following benefits. HDD not only makes traffic disruption less and deeper or longer installation possible, but ensures a lower cost and environmentally safer.

GN Solid America is specialized in design and build up mud recycling system for HDD rigs, and for a decade’s innovating and evolving, GN’s mud system is widely used in Australia, India, and other countries for HDD rigs.  The below features  are proof of GN’s mud systems popularity. Firstly, GN provides compact design with a combination of mud cleaner and underflow shaker, which is double deck for the first stage separation and drilling mud’s drying.

Secondly, GN supplies a full range of mud system:150/ 350/ 800/1000/1500GPM.

Thirdly, GN offers cost effective equipment integration from a single source: GN Solids Control factory.
