General Cleaning
Outer Frame
The Hoppmann Model FR-20 & FR-30 Centrifugal Feeders
are not
& Tooling
intended for washdown use. If you need to clean the outer frame,
safety covers or tooling, use a mild household cleaner.
Bowl & Rigid Disc:
The bowl and rigid disc are self-cleaning when handling most
"Dusty" Applications
product; however, if your product generates dust or particulate
when handled, clean the feeder as often as necessary. For such
product, remove dust from the top surface of the rim of the bowl
and the rigid disc with a portable vacuum cleaner or dry compressed
air.
Lubrication
Bearings
On all FR-20 and FR-30 models, grease nipples for lubrication are
located on the outside of the upper and lower spindle bearings.
Use any lithium grease conforming to NLGI Grade 2 consistency;
the grease should be free of dust, particles and abrasives.
Instead, use the maximum grease capacity of the bearings as a
guide; the upper spindle bearing can hold up to about
3
/
8
ounces
of grease; the lower spindle bearing can hold up to about
1
/
8
ounces
of grease. Lubricate every 6 to 12 months or 1000 operating hours,
whichever comes first.
Because of the danger from moving parts, do not lubricate while
the feeder is operating.
Chain & Sprockets
After greasing the bearings, grease the drive chain, spindle sprocket
and torque limiter sprocket every six months or 1000 operating
hours, whichever comes first. Use standard Moly grease, Lubriplate
#3000 (NLGI Grade 2) or equivalent.
