• insufficient crusher discharge area
• extremely hard or tough material
• operating Crusher at less than recommended
full load countershaft speed
Capacities are based on results obtained from
installations worldwide, crushing the broadest
range of ores, rocks and minerals. To determine
effect of individual conditions, consult Metso
Minerals.
1.7 Selection of Proper Liners
Through extensive research and study, Metso
Minerals has developed a varied line of crushing
members covering a wide range of feed and product
sizes. Since there are so many variable conditions
and types of operation to be considered, it would be
difficult to list each type of liner that would be best
suited for each individual condition and type of
operation.
If for any reason, it is felt that unsatisfactory wear
life was obtained from the original liners, Metso
Minerals suggests that the bowl liner and mantle be
torch cut open so that the contour of the bowl liner
and mantle can be traced onto a sheet of cardboard
or heavy paper and the traced contours sent to the
factory, in order that the exact concentration of
wear can be determined, refer to Figure 1-1.
Another bowl liner and mantle can then be
recommended which will have a different contour
at these wear points.
In order to properly answer any inquiry, it is
important that the following information be
included:
•
feed gradation
• type of feed. (i.e. granite)
• product gradation
• circuit diagram complete with screen cloth
openings and all crusher settings
• part numbers of current mantle and bowl liner
• crusher power draw
• crusher capacity
To operate continuously with liners having a
crushing cavity unsuited to the operation, results in
uneconomical wear of the liners, poor crushing
efficiency and, in some instances, abuse to the
Crusher.
