AMIT 135: Lesson 5 Crushing – Mining Mill Operator Training
Crushing Equipment. The selection of the right crushing equipment is influenced by many factors some of which are upstream of the crushing plant (e.g. blasting pattern and mining method) and others which are downstream of the crushing plant (e.g. mill and grinding circuit selection).

What Is The Significance Of A Choke Point?
A choke point is a feature on land or at sea including valley, defile, and strait which a military force is required to pass through. The choke point is sometimes substantially narrow, significantly reducing the effectiveness of the military force. A choke point allows a numerically inferior army to attack and overcome an opponent with a …

These are the volume limit, the horsepower limit and the crushing force limit. Regarding the volume limit, each crushing cavity has a volumetric limit that determines maximum throughput, and a choke-fed crusher is operating at its volumetric limit. The volume limit is exceeded when feed material overflows the top of the crusher.

1. Introduction. When a liquid flows through a nozzle, the flow rate tends to increase as the nozzle outlet pressure is lowered. This only holds up to a point; below a certain outlet pressure the flow rate remains constant at a maximal value (Amos and Schrock, 1983).This is referred to as critical flow or, alternatively, choked flow.
