Section 6 – Maintenance
Wear parts
It is normal for wear to occur on the mixing shaft, and in the mixing nozzle. The rate of
wear is very dependant upon the materials being mixed and the throughput of the
machine.
The feed / metering section of the mixing shaft is also subject to wear, as is the wear line
assembly
The mixing shaft is made of 3 sections each part is individually replaceable. The wear
liner assembly is also available as a replaceable part.
Maintenance
Apply a petroleum based grease such as “Vaseline” to the lip of the mixer seal after each
cleaning, to help allow easier nozzle assembly.
Each week the motor flange must be greased using a good quality general purpose water
proof grease. Pump the grease until it can be seen slightly oozing from around the hauling
bracket seal. Wipe off any excess to prevent immediate material build up.
After each clean down, grease the external square bore mixing nozzle bearing, until
grease can be seen “oozing” from the bearing seals.
Do not grease any of the mixing shaft connections as the lubricant will attract material
and cause premature wear.
Check the condition of the mixing shaft parts on a regular basis, and ensure that they
fully engage with each other. Check for the level of “play” between parts and replace
when they become “loose” or increased levels of wear will occur on other mating parts.
Check that all fasteners are fully assembled and tight at all times.
Ensure that the water control is free of leaks and that the system is drained if being stored
or not used, in freezing conditions.
Replace any bent, damaged or torn parts immediately to prevent further damage to the
machine and / or personnel.
Ensure that the safety grid is always replaced after any hopper or shaft maintenance.
Check the condition of all electrical connections a shift by shift basis.
Clean the whole machine on a shift by shift basis.
