A crusher is choke fed when the chamber is full and there is material above to keep it full. This contrasts with regulated feed, where the flow of material to the crusher is throttled in some manner so that the crusher is never completely filled. Aa particle moves from level to level it drops a greater distance with each movement of the mantle.
It will explain how the effect of choke feeding the gyratory was measured and from that, the various changes made to improve choke feeding of the gyratory crusher.

Mining of raw materials is a process that consists of several stages. In open-pit mining, material with high compressive strength is extracted by drilling and blasting and material with low compressive strength is extracted by e. g. a bucket wheel excavator. Most important influencing factors for crusher decision are compressive strength, moisture content, capacity of …
Environmental Impact Assessment is the process of evaluating the effects caused by a project on the environment. The outcomes generated by this assessment can lead to a reduction of the negative ...
This is the starting point for understanding how cone crushers work – and how they can make your mine or quarry more productive. ... CH cone crusher. The open side and closed. As the feed is crushed, it falls and exits the crusher through the space at the bottom. The eccentric gyration of the mantle means that at any moment this space ...

A method for estimating the crusher model parameters based on Axb value was introduced. Abstract. In hard rock mining, blasting is generally the first operation of rock fragmentation from its in-situ state. ... Since coarser grind size can have a negative effect on recovery, there is a trade-off between throughput and recovery. ...
Contrary to the adverse effects of mining on crop productivity, Ambastha and Haritash ... Further, the results indicated that soil quality was worse closer to the crusher site than it is farther away. For instance, the pH value near a crusher unit that produces a lot of dust was >10 within 100 m, and it drops to 8.2 m away from the center of ...
For example, the effect of ore crushing on the shovels of the Gol-e-Gohar iron ore mine was presented with a mathematical model to determine their production levels. This model was obtained using data that differed from …
The effect of the undersize in the feed upon the capacity of the crusher depends upon several factors. If the crusher is a primary breaker, and the discharge opening is large, undersize will usually sift readily through the voids between the large pieces of material, and discharge quickly. The material must, of course, be free-flowing to behave ...
