Operating the
Grinder
The operation of the feed chain, the discharge conveyor,
the compression roll, and the grinder assembly are coor-
dinated by a combination of manual control and elec-
tronic logic, called the Peterson Adaptive Control
System.
For more information on automatic control of the feed
system, see “Peterson Adaptive Control System” on
page 118.
This section covers the following aspects of running the
machine:
•
How to begin processing material
•
How to control the machine while grinding
•
How to perform the necessary inspections for wear
during the work day
Important
While grinding, inspect the machine at regular
intervals (see “Daily Checks for Wear” on page 76).
