A proper choke-fed cavity level should be pursued as it will increase crusher throughput tonnage and result in a more cubical product – especially with tertiary (short head) crushers that make the most of the producers' salable products. Avoid trickle feeding the crusher; Try not to trickle feed a cone crusher.

It is very important to choke feed your cone crusher to ensure even liner wear and thereby extending the life of the liners. This will also ensure that the machine will run smoother and increase your quality of product and production rate.
Maximize Jaw Crusher Liner Wear life (7 replies) (unknown) 6 years ago Ensure that the jaw chamber is choke fed. The level of material in the jaw should just be below the jaw stock deflection plate. I wonder how you extend the life of jaw liners And Reduce volume of fines and wet material entering the crusher. Zander Barcalow 6 years ago Like
For industrial jaw crushers, the choke feeding intensity is not considered a critical phenomenon in initial rock breakage. However, the choke feeding intensity is highly dependent upon the m f in the crushing chamber. The more the m f in the crushing chamber, the more fine particles will be produced owing to intense choke feeding activity .
Jaw crushers are routinely choke fed, as this maximizes production capacity and ensures particles are uniformly broken. This promotes stone-on-stone crushing, breaking up flaky or slabby particles. If you seek fewer fines, trickle feeding material into …
Cone crushers are fed with pre-screened material from the primary crusher (usually a jaw crusher or primary gyratory), and the secondary crusher should always, if possible, have a scalped feed. Ideally, the deck on the scalping screen should have a cut point equal to the closed side setting (CSS) of the crusher
The crusher should be choke fed so that the crushing chamber is full all the time. This is important, especially in fine crushing. Choke feeding maximizes the amount of multilayer crushing and improves wear shape and crushing efficiency. Choke feed level for the AF secondary crusher is at the level of the mantle fixing nut.

Jaw Crushers are sized by the top opening of the crushing chamber. For example, a 32 x 54 Jaw Crusher measures 32" from jaw die to jaw die at the top opening or gape opening and 54" across the width of the two jaw dies. The narrower bottom opening of the crushing chamber is used to size the discharge material.
jaw crusher information and illustrations. Information on cone crushers, … CHOKE FEED Jaw crushers should be fed a consistent rate of feed that will result in the crushing chamber being kept full at all times.
Gyratory crushers are known for their high production rates, with a higher capacity than a jaw crusher. In order to get cubical material out of a gyratory crusher, it should be choke fed. Gyratory crushers are not suitable for crushing clay, as clay will clog the crusher. Construction and Working of Gyratory Crushers
Like the jaw crusher, the cone crusher provides a relatively low cost crushing solution, but there are application drawbacks that may make another crushing solution more appealing. First, cone crushers cannot accept all material sizes. Any material fed to the crusher must be pre-sized for that particular crusher (usually 200mm or less).
1. Check the feed arrangement: • The crusher should be choke fed so that the crushing chamber is full all the time. This is important, especially in fine crush-ing. Choke feeding maximizes the amount of multi-layer crushing, improves the shape of the crushing cavity as it wears and improves the crushing efficiency. => Choke feed level varies.
• The crusher should be choke fed so that the crushing chamber is full all the time. This is important, especially in fine crushing. Choke feeding maximizes the amount of multi-layer crushing, improves the shape of the crushing cavity as it wears and improves the crushing efficiency. => Choke feed level for an HP cone crusher is 300 mm or more
Ensure that the jaw chamber is choke fed. The level of material in the jaw should just be below the jaw stock deflection plate. I wonder how you extend the life of jaw liners And Reduce volume of fines and wet material entering the crusher.

The product from crushers of the standard gyratory type, or the older reduction types, as well as all types of jaw crushers, will be affected to some extent by the method of feeding; that is, whether the machine is choke-fed or not.
In addition, the jaw crusher cannot be choke-fed, as can the other machine, with the result that it is difficult to keep it working at its full capacity— that is, at maximum efficiency. Tables 5 and 6 give particulars of different sizes of jaw crushers.
With the measured results of the compressing force on the liner, the research on crushing force in jaw crusher is developed. Under a choke feed level the experiments to …
Ideally, the feed rate should not be switched from choke to non-choke, as this would cause problems downstream at the secondary processing plant. In practice, many jaw crushers are fed in this intermittent fashion due to gaps in …
The classification of the jaw crusher: In mining, building materials and infrastructure sectors, the jaw crusher is mainly used as primary and secondary crusher. According to the width of the feed opening, it can be classified into three kinds—large, medium and small crushers. The feed opening width of the large jaw crusher is greater than ...

To optimize operating costs and improve the product shape it is recommended that cone crushers are always be choke fed, meaning that the cavity should be as full of rock material as possible. This can be easily achieved by using a stockpile or a silo to regulate the inevitable fluctuation of feed material flow.
In this study, the effects of three different choke feed level (1/1, 1/2, and 1/4) and four different effective reduction ratios (2.5, 5, 10, and 20) depend on the capacity of the crusher of the ...
Jaw crushers can be divided into two basic types, single and double toggle. In the single toggle jaw crusher, an eccentric shaft is on the top of the crusher. ...

Jaw crushers are routinely choke fed to maximize production capacity and ensure that particles are uniformly broken. This promotes stone-on-stone crushing, which breaks up flaky or slabbier particles. Those seeking fewer fines should try trickle feeding material into the jaw crusher.
Unlike jaw crushers impactors do not run on the choke fed theory. Jaws and cones need to be choke fed as they work on gravity and compression. Where as impact crushers work on actual impact force (inertia) from the rotor and blow bars that impacts the rock. If you are over feeding the chamber you risk boggin down the crusher and limit the ...
For example, jaw crushers using this method of compression are suitable for reducing extremely hard and abrasive rock. As a mechanical reduction method, compression should be used for the following. ... Choke Feed Operating the crusher with a completely filled crushing chamber. Choking Stoppage of the flow of material through the crusher, which ...
For maximum size reduction, as when preparing feed material for jet milling, the rolls can be choke fed. Construction Our roll crushers are all steel construction for maximum strength and longevity. These too use high tensile bushings and bolted connection – no castings or welds to stress crack and break.
