SETTING
The setting is the minimum distance between
the concave and mantle during the work cycle.
It must be measured at the lowest point of the
mantle. The setting determines the maximum
size of the discharging material, crusher
capacity and load.
The easiest and most accurate way to measure
the setting is to lower a piece of lead with a
wire through the crushing cavity when the
crusher is idling, lift it up again and check the
thickness of the compressed lead (figure
5.6.1). A piece of lead is included with the
crusher in the tool box.
Because the liners might wear unevenly,
measure the setting in three or four points
around the cavity and use the average as a
setting. Too small of a setting increases the
load of the crusher remarkably. For minimum
setting, see chapter 3.5.
When the crusher is equipped with automatic
control system (Lokoset or equivalent), the
crusher should not be used without it. When
adjusting the setting (main shaft position), the
control system must be connected and in use.
Only during maintenance the setting may be
adjusted without the control system, using the
switch located in the lubricating device.

STROKE
The stroke length has effect on crusher
capacity (the longer stroke, the higher
capacity) and quality of the product.
