Cone crushers and jaw crushers both work by compression, reducing materials by squeezing them until they break apart. The benefit that cone crushers offer over jaw crushers is their ability to output a more cubical product similar to impact crushers. Cone crushers have traditionally been used as secondary and sometimes tertiary crushing ...
Here is cone crusher arranged with a Level Sensor interlocked with the feed conveyor. It keeps the crusher feed cavity full for best choke feeding.
Here are some reasons why choke feeding is beneficial for cone crushers: Improved Crushing Efficiency: Choke feeding ensures that the cone crusher is always working at or near its optimal capacity ...
Cone Crusher Function. A cone crusher has an annular crushing chamber. The CSS runs around the chamber so the action is basically rotational. Raw material enters the chamber on the OSS and is crushed one. h alf revol uti on l at er b y th e CSS. This cycle takes place in most cone crushers 5 to 6 times per second.
Cone Crusher Components. Top Shell & Spider Cap Assembly. The feed is fed by conveyors to a feed bin above the vertically mounted cone crusher. Feed enters the crusher via an opening in the upper shell. Depending upon the cone crusher design, a distribution plate may be used to distribute the feed evenly as it enters the crusher.
Here is what a well choke fed jaw crusher looks like! Too many mines run these jaw crusher cavity like a funnel without any choking. Operators must keep the …
In a nutshell, choke feeding a cone allows it to best do its job. A choke feed will provide rock-on-rock crushing for best cubicity, best liner wear, and best use of power. Another …
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.

Choke-feed implies a completely filled crushing chamber (or as full as the design will permit), with a sufficient head of material above the receiving opening to keep the crusher full continuously. This contrasts with regulated-feed, which implies that the flow of material to the crusher is throttled to a point somewhat below the capacity of ...

A good rule of thumb is that the maximum feed size should be 80% of the crusher opening. If the crusher opening is 30", a 24" feed top size is recommended. 4. Scalp out the fines by pre-screening the feed. Fines in the feed can limit production for several reasons. They can clog the crushing chamber, reducing the tons per hour and ...
The difference between the cumulative percentages at the 3.5″ and 1.5″ points on the curve gives us the amount, of such product to be expected from the output of the primary crusher This is 85 minus 43, or 42% of the primary crusher product. If our problem had covered a crushing condition calling for 80 instead of 85% passing the …

The reduction ratio in crushing is the ratio of the feed size to the product size during a crushing operation. It usually varies, but the reduction ratio depends on the chamber and nut adjustments. However, the best particle shape is found in material about the same size as the CSS, which is the smallest discharge opening dimension on the jaw ...

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. This will also ensure that the machine will run smoother and increase your quality of …

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. In a perfect world, you would not change your feed rate often.

GP500S™ is one of the GP Secondary cone crusher models. GP Secondary cone crushers are specifically designed for sometimes demanding secondary crushing stage where the feed flow may variate, and the feed size can be anything between extra coarse and extra fine. GP secondaries' main feature is the capability to accept extra-large feed ...
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.
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 crushing. Choke feeding maximizes the amount of multi-layer crushing, and improves wear shape and crushing efficiency. 1. Choke feed level for GP secondary crusher is at the level of the

1. Keep the crusher choke-fed. Choke feed means to keep the head covered with at least 150mm of feed material. Conditions that help keep the crusher choked include surge bins, bin level sensors, adjustable speed feeders, and automation. 2. Stable, continuous feed. The gradation of the feed material should be continuous from …
