Metalfab Model CB-1 Continuous Blender - Manual (Page 2)

The blender must be “primed” in order to maintain the proper mix.
The first few minutes of discharges material should be discarded to
achieve the “prime” cycle. After this, there is no need to repeat the
cycle unless the blender is allowed to run empty.
Maintenance
Because of its simple design, there is little need for maintenance. The
only bearings (front and rear) are grease lubricated for life. A grease
fitting is supplied, but its use is optional.
The speed reducer is also lubricated with grease and it should not need
any maintenance for five (5) years of continuous duty.
The blending screw is also built to give years of service with no
maintenance requirements.
The only possibility of damage is the introduction of foreign matter into
the mix chamber. This may mechanically harm the screw. Also if the
particles blended are highly abrasive, the screw will wear after some
period of time.
If the screw must be removed, the following sequence should be
followed.
1. Undo the setscrews on the forward bearing.
2. Remove the bolts from the front flange and remove it.
3. Undo the setscrews on the rear bearing and coupling half.
4. Pull screw forward until it is completely removed from the
forward end of the unit. Allow enough room to allow for the
removal.
To reinstall, follow the above in reverse.
WARNING: Keep hands clear of moving parts – serious
injury can occur!
Electrically “lock-out” motor prior to any
disassembly.
