6.4 Cleaning
your
machine
The design and construction of your machine allows for disassembly without the need for
specialized tools.
Complete disassembly of all parts is required for thorough cleaning or washing.
All
metal parts which contact products being processed are constructed of stainless steel and
may be cleaned with hot water or steam. When materials processed are not water soluble,
solvents or steam may be used for cleaning under proper safety conditions. Care should be
taken that bearings are kept dry and lubricated. Care should also be taken that cleaning
agents or solvents used are chemically compatible with elastomers and metals used in the
construction of your machine (refer to your BOM and assembly drawings for parts details).
Highly chlorinated cleaning solutions (e.g. bleach) are to be avoided as these can be
harmful to stainless steel.

Screen Carrier Assembly Installation
The Mill Screen Carrier Assembly is symmetrically designed to clamp a milling screen
securely and slide in the chamber easily with the anti-galling retainers and inserts.
Use the screen carrier pry bar
(see section 7.2 tools) to aid in
removal from the chamber. The
carrier assembly has anti-galling
side and bottom bolted inserts
which do not require any normal
attention.
Installing mill screen: seat the screen
in the carrier and while holding down
the
screen firmly, check that the screen
profile matches the carrier profile
closely.
Re-bend the screen if large gaps are
observed. Again while holding down
the screen firmly, screw down one
screen retainer securely using a flat
tipped screwdriver.
Screw down the second (2
nd
) screen
retainer to lock the screen in place
