Primary Crushing Best Maintenance Practices and Application

CHOKE POINT • The choke point of the crushing cavity is a zone of minimum capacity. It is that point or zone in the chamber where the volume of material can approach a solid mass. • The material can become compact, restricting progress down to the next crushing zone, drastically reducing capacity. This is known as the choke point.

Feb 17, 2016  The choke-point in a crushing chamber is that level in the chamber where the capacity of the crusher is a minimum; that is, it is the bottle neck of the crushing chamber. It follows that it is the point where choking is most likely to occur, particularly so if the choke is promoted by a condition existing within the crusher.

Choke Feeding a Jaw Crusher What is Choke Feed Looks Like

Mar 21, 2014  Too many mines run these jaw crusher cavity like a funnel without any choking. Operators must keep the jaw’s cavity full to maximize rock-on-rock compression and crushing. Notice the shape of the liner profiles? A crusher is choke fed when the chamber is full and there is material above to keep it full.

Cone Crushers McLanahan

A Cone Crusher is a compression type of machine that reduces material by squeezing or compressing the feed material between a moving piece of steel and a stationary piece of steel. Final sizing and reduction is determined by the closed side setting or the gap between the two crushing members at the lowest point. As the wedge or eccentric rotates to cause the compression within the chamber, the ...

Maintenance of the wear components in both gyratory and cone crushers is one of the major operating costs. Wear monitoring is possible using a Faro Arm (Figure 6.10), which is a portable coordinate measurement machine.Ultrasonic profiling is also used. A more advanced system using a laser scanner tool to profile the mantle and concave produces a 3D image of the crushing chamber (Erikson, 2014).
