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.

Cone Crushers | McLanahan

Cone Crusher Applications A general rule of thumb for applying Cone Crushers is the reduction ratio. A crusher with coarse style liners would typically have a 6:1 reduction ratio. Thus, with a 3⁄4" closed side setting, the maximum feed would be 6 x 3⁄4 or 4.5 inches.

Common Crushing Industry Terms & Vocabulary

 · 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.

Output prediction of cone crushers

Output prediction of cone crushers

 · Repeat point 2 to 5 until the location of the upper zone boundary has passed the inlet of the chamber. The boundaries of all the crushing zones are now determined. If the crusher is choke-fed the total capacity is given from equation (2).

Factors Affect Crushing

It is entirely possible for a crusher to choke at some other point in the crushing chamber than the theoretical choke-point. When the setting of a fine-reduction crusher is too close for its eccentric throw and for the general proportions of its crushing chamber, there is a tendency toward building up a choke in the zone immediately above the discharge opening, regardless of where the ...

An evaluation of the procedure and results of laboratory …

 · Crushing was carried out in two stages; the second stage by choke feeding the crusher. According to Briggs and Evertsson ( 1998 ) choke feeding causes a multi-point loading stress field on aggregate particles which results in cracks that are located within the edges of the original particles.

Improved flow

 · The distance a particle falls during a stroke is called a crushing zone. The amount of material that enters the inlet zone, i.e. the first crushing zone, determines the capacity of the crusher. During operation at normal eccentric speeds the material does not entirely fill the inlet zone due to dynamic and boundary effects.
