The angle of nip in gyratory crushers has definite limitations. In the older straight element crushing chamber, the angle ranges from 20" to 24". On large primary crushers, using curved or nonchoking concaves and where gravity is of marked aid to nip with the large pieces at the mouth. the angle runs from 25" to 30°.

If cone crusher maintenance is neglected, the result will be a detrimental effect on productivity and an overall higher energy cost per ton of material crushed. It’s not uncommon that aggregate producers’ maintenance teams are not fully aware of the maintenance requirements of a cone crusher or its impact on energy consumption. Make sure that at least these five things are checked.

Trickle feeding a cone crusher should be avoided because it not only results in poor productivity and poor product shape, but it can also adversely affect bearing alignment within said crusher. Due to the operational characteristics of a cone crusher, when crushing, it should never be operated below 40 percent rated horsepower. To obtain a proper “loaded bearing alignment” and to maximize

Cone crushers are built with a rotating mantle in a concave bowl lined with manganese—this is similar to gyratory crushers, but the crushing chamber in cone crushers is not as steeply angled. Cone crushers can accept medium-hard to very hard and abrasive feeds that might be dry or wet, though not sticky (whereas gyratory crushers are better at handling softer, dryer feeds).

Some cone crushers use bushings while others use bearings. Bearing cone crushers tend to run cooler and are more efficient than bushing crushers, and they allow the user to apply more horsepower during crushing without generating excessive heat. Bushing cones create more heat and require lots of lubricating oil and more active cooling systems

The optimal arrangement for a cone crusher is to choke feed it with a non-segregated feed. This will help the crusher run more smoothly by lowering both power and pressure peaks and improving overall performance. Choke feeding is about maintaining a constantly high level of evenly distributed material in the feed hopper.
