1.1 MOBILISATION
In most cases a 10 ton/meter crane will be enough to mobilize this mixing unit.
Prior to lifting the mixing unit a few checks must be made:
1. check if all stored articles on the mixing unit are securely tied down
2. take the ignition key out of the control panel
3. make sure the mixing tank, pump and piping is drained and cleaned
4. open all valves
When all this is done you can hook up the lifting chain.
Use a rope, tied to the unit to steer and/or turn the unit when it is lifted.
NEVER:
1. stand or walk underneath the load
2. use chains that are to short, to light, or have uneven lengths
3. use uncertified lifting equipment
NOTE:
WHEN PLACING A RECYCLING SYSTEM ON THE MIX UNIT ALWAYS USE TWIST LOCKS BETWEEN THE CORNER BLOCKS
TO CONNECT THE CONTAINERS.
1.2 PLACING THE MIXING UNIT ON SITE
Before you place your mixing unit on its site location, there are a few preparations you can do:
1. place a sheet of 4x4 meters of oil resistant plastic foil on the location of the unit
2. place 3 drag line boards each at least 3 meter long horizontally, well supported by solid soil, on top of the plastic
foil.
3. if you decide not to use the plastic foil: always use drag line boards or something similar placed horizontally to give
the mixing unit its full support and to create a non slippery working floor
When all this is done you can unhook up the lifting chain.
Now the connections have to be made:
1. Water : 2’’ id BSP thread
2. Mud discharge : 2’’ victaulic with banjo female
The installed power is:
1x 11 kW hatz diesel

1.3 OVERALL CHECK OF THE MIXING UNIT
Before you can start mixing there are a several checks to be made:
1. Check for debris in the mixing tank
2. Put 2 pump strokes of high quality bearing grease in all nipples on the GORMAN RUPP pumps.
3. Check if all electrical cables and wires are still in good condition, repair if necessary.
4. Check, overall, for any damaged or loose parts and repair if needed.
5. Check all guards.
6. Check the tank for cracks.
1.4 CAPACITY PARAMETERS
This unit is capable of mixing 250 ltr/min with normal fresh water, 7 ph and up to 60 sec of viscosity.
2.1 CHECK BEFORE STARTING THE MIXING UNIT
Before starting the unit you must do a quick check of all components of the unit:
1. Check the pump: - fluid levels
- debris plugging suction
2. Open suction valve and close drain valve
2.2 STARTING THE MIXING UNIT
First make your self acquainted with the valve schedule in 5.3.
1. To start the mixing unit, fill the complete unit for 3/4 with water.
2. Open suction valve mix pump from mix tank nr.1.
3. Close the air bleed valve on the impeller housing of the mixing pump when all air is out of the pump.
4. Open the discharge valve from pump to venturi nr.2
5. Start diesel engine
6. Now you can start mixing bentonite with the unit: open the valve of the hopper approx. half way.
7. Now suction noise will be heard out of the hopper funnel. Slowly add bentonite.
8. Add bentonite until required mud-viscosity is reached.
9. Open discharge valve to nozzles.
10. Run the unit for a few minutes: keep in mind that the viscosity of the mud will increase in this time as the mud is
being sheared
As mud is being used the fluid level inside the mixing tank must be maintained: add water and bentonite on time and, if a
mud recycling system is used, keep a eye on the mud level of the mud pit, with a SiteTec recycling system, mud will be
transferred from the recycling unit to the mixing unit. This means you have to add very little bentonite and/or water, just to
keep the mud level in the mixing tank to its maximum and in the right condition.

2.3 OPERATING THE MIXING UNIT WITHOUT RECYCLING SYSTEM
To maintain a continuous mixing process add water and bentonite in the correct ratio. And a minimum of 250ltr water per
min.
2.4 OPERATING THE MIXING UNIT IN GENERAL
When the mixing unit is in service the responsible mud man has to keep checking all items discussed in chapter 1.3 and 2.1
on a regular basis. Extra to that is checking mud level in the mixing tank and keeping the right viscosity of the mud.
Fill the tank with water for at least ¾ open venturie valve and slowly the hopper valve, make sure that al the other valves are
closed. Start adding dry product at the right ratio. When you have a right mixture close hopper valve.
When mixing only open venturie valve and hopper valve, when circulating and using outlet always close hopper valve.
Only open max 2 valves at the same time, the operator has a choice between nozzles with venturie for max circulation or
nozzles with outlet to HP pump.
If no mud is used you can close the valve of the hopper and stop the mixing pump.
This reduces wear of the unit. Do start-up before mud is needed!
If no mud is used you can close the valve of the hopper and stop the mixing pump.
This reduces wear of the unit. Do start-up before mud is needed!
Never start the pump without de-aerating the pump or without fluid.
In case of use of recycled fluid, mount stainless eductors/tank nozzles in the tank.
2.5 SERVICING ON THE MIXING UNIT AND EXCHANGING PARTS
1. Before you start working on the unit, stop all functions and switch off the main switch.
2. Disconnect main power cable.
3. Before you start working on the pump close all valves and drain the pump.
