Start-up continued...
Check each mixer for proper operation by running the mixer in both forward and
reverse directions (if unit is so constructed as to allow reverse direction).
Next, start the delivery pump to discharge the water that was previously introduced into
the pump hopper. This is an ideal opportunity to check the grouting system to
determine that all lines and hoses are clear and unobstructed. Pump condition may also
be checked at this time by testing the discharge pressure.
Pump water through all the hoses.
Remember to never let the hopper run dry.
When it is determined that all systems are normal, shut off the pump and
drain the
water from the pump and all lines.
Priming
Make a mix of cement and water at a ratio of 1:1 ie 20 lts water per 20 kg of
cement and pump this through the system inc hoses.
To do this firstly add the water then slowly feather in the cement, never dump all
the cement in one go as this will create lumps and may stall the mixer.
This prime mix is used to remove any residual water from the hose, lubricating it for
the production material to follow.
Now the production grout may be mixed and pumped immediately behind the
slurry mix, which is thus evacuated from the hose, and may be retrieved in a
bucket/ibc.
Do not attempt to pump production material through a dry hose or non primed hose.
Production

one go as this will create lumps and may stall the mixer.
