Can you be more specific? If you mean get more power out by "up scaling" then you have to put more power in, that is bigger motors, and drive units. If this is a design project simply build in the higher throughput. If it's an existing plant all you can do is eliminate inefficiency, spillage etc. Crushers are often a batch process so you can up scale by reducing down-time, but overloading equipment will increase downtime not reduce it, look at the screen decks- can you put in longer wearing screens so you don't have as many to change. Increase mill feed and you will get a coarser product- this may reduce separation so small steps. Cyclones can increase flow if you increase the static head - or depth of pumpbox, but this may not be possible in the design. Filters agitators thickeners all can be increased but a bent agitator shaft will cause extensive down-time. pipes and sumps have some variance but too big a pipe will sand-out, too small will wear through. So you really are limited to just ensuring maximum efficiency and tweaking motors that are slowing down specific sections.

For avoiding batch operation of the equipment like crusher, there sholuld be controlled feeding so that the equipment is always loadd optimally for best performance.
