The RSM results demonstrated that the characterized feeding size (F 80, mm) dominates the general size reduction, whereas the feeding quantity (m f, g) is associated with the crushing energy consumption and product flakiness. Therefore, the choke feeding intensity has a direct relation to the m f and F 80. In addition, novel gene …

Crushers should have all of their guards and safeties in place before operating. When feeding the machine, use choke, non-choke or trickle feeding when necessary and ensure you use the correct feed in primary, secondary and tertiary crushing methods. 4. Keep the Operator Isolated.
Illustration of choke feeding intensity for an industrial jaw crusher a) Fully loaded feeding bunker b) Uncontrolled choke feeding intensity in the crushing chamber. In this direction, the present study explores the DRC variations due to varying feeding properties using a laboratory scale jaw crusher.
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 …

The purpose of the primary crusher is to reduce the ROM ore to a size amenable for feeding the secondary crusher or the SAG mill grinding circuit. The ratio of reduction through a primary crusher can be up to about 8:1. Feed: ROM up to 1.5 m; Product: -300mm (for transport) to -200mm (for SAG mill) Feed Rate: 160 to 13,000 tph
Various feeding sizes (9.5 – 19 mm) and quantities (500 – 1500 g) were adopted to reveal the choke feeding intensity during crushing actions. The efficiency of feeding properties was investigated through the response surface methodology (RSM). ... such as crusher performance, feeding method, and rock properties. All these …
The adjustable stroke also allows you to attain proper choke feed conditions and optimum crusher settings, ensuring the maximum yield of a required end-product size. The crusher automation, on the other hand, …

CHOKE FEEDING IS A MUST At the top of Thistle's list is keeping the cone crusher choke fed during operation — a practice that maximises the effectiveness of rock on rock crushing, which in turn maintains maximum manganese wear life and ensures a quality product shape. He stresses that it is common to see crushers operating with too …
Choke feeding. Jaw Crushers work best when the entire crushing chamber is used for material size reduction. Choke feed a Jaw Crusher to maintain a crushing …
This limits opportunities for the material to clog the crusher. Choke feeding is the next… "Jaw crushers work best when the entire crushing chamber is used for material size reduction," the team explained. "Choke feeding a jaw crusher to maintain a crushing chamber that is at least 80% full will help to draw the material down into the ...
Its unique crushing action provides excellent capacity, high reduction, and good product cubicity for the production of high-quality aggregate and sub-base materials. A level probe over the feed ring regulates the feed belt to ensure the cone chamber is choke fed, essential for maximum reduction, manganese life, and optimal product shape.
Keeping the cone crusher choke fed. Maintaining a continuous feed to the crusher is essential to greater manganese wear life. Choke feeding means keeping the cone head covered with at least 150 mm of consistent, homogenous feed material. Most operations use a combination of hoppers, feeders and surge bins to achieve optimum …

The reduction ratio is driven by the Crusher Close Side Setting. The actual minimum safe closed side setting of a crusher will vary somewhat, for any given crushing machine, depending upon the character of the material, the amount of fines in the feed, and whether the crusher is being operated under choke-feed or regulated feed conditions. …
Choke feeding a cone crusher, whereby a head of material is maintained in the chamber, provides rock-on-rock breakage (Evertsson, 2000). Jacobson and Janssen (2010) studied the effect of varying cavity level inside a high-speed cone crusher chamber in relation to capacity, power utilization, and size reduction properties. They concluded …
The Importance of Choke Feeding a Cone Crusher. (Applies to the Cone Crushers UD211, QH331, QH440, US440 and UH440) It is very important to choke feed your cone crusher to ensure even liner wear and thereby extending the life of the liners.

Feeding Your Jaw Crusher. Jaw crushers are often choke-fed to maximize production speed. Choke feeding results in stone-on-stone crushing, which can help break apart more flaky materials. However, choke feeding also often results in a finer output. Trickle-feeding will result in larger products but also reduce capacity and jaw crusher efficiency.
The best way to ensure optimal liner life is to choke feed your Cone Crusher. Choke feeding allows a full chamber with material on top to help force the material in the chamber through.
