Weir Minerals updates Trio live-shaft cone crusher range ...

The ability of the TC84XR crusher to handle variable feed and crush pebbles is also partly a result of its large motor; it's been designed with higher power capability than comparable cone crushers. Ultimately, this translates to a higher potential crushing force and, therefore, increase in production, Weir said.

Orphan Espresso Apex Grinder - Page 76

I'd suspect that it is the feed rate, as the lower the feed rate, the less fines produced. 1. If you have the spring auger installed clockwise, then grinding CCW will greatly reduce the feed rate; 2. Grinding with slower rpm reduces the feed rate; and 3. Part of the burr is directional, but the direction slows feed rate, not...

Avoid Unplanned Downtime: 5 Crusher Maintenance Best …

"Also, you want to choke feed the crusher to get maximum production rates and a 360-degree crush." Don't trickle feed the crusher; that will lead to uneven component wear, more irregular product sizes and less production. An inexperienced operator will often reduce the feed rate rather than to simply open the close side setting.

Ideally, the reduction ratio of a jaw crusher should be 6-to-1. There are different ways to calculate reduction ratio, but the best way is something called the P80 factor. The reduction ratio is then calculated by comparing the input feed size passing 80 percent versus the discharge size that passes 80 percent.
