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 above the feed plate. • The feed must be distributed evenly 360º around the crushing

It makes the primary crusher more efficient by supplying a constant, metered rate of feed to the crusher and by pulling fines from the feed material to keep it out of the crushing chamber. VGFs handle a variety of material types: from large shot rock to sand and gravel, and from high clay aggregate to recycled concrete.

While it is beneficial to retain some feed below the CSS, it is advisable to screen fines (-5mm) out of the feed to minimise compaction and avoid a tramping condition where the crusher will relieve under high pressure. 4. Restrict final stage reduction ratio to 3:1.

In general, fine jaw crusher and cone crusher have the following characteristics: The feeding granulation range of fine jaw crusher is relatively large, which can generally handle materials below 1000mm, while the cone crusher is relatively strict and generally requires less than 300mm (depending on the specific situation of the product).

Fines (for example, 0–4 mm) should be screened out before the material is fed to the crusher as the fines may cause packing: this is a force overload and can be seen as adjustment ring movement.

"Fines in the crusher feed" is defined as material entering the top of the crusher which is already equal to or smaller than the crusher''s closed-side discharge setting. As a rule of thumb, the maximum number of fines in the crusher feed should not exceed 25 percent for secondary crushers or 10 percent for tertiary crushers.

Those seeking fewer fines should try trickle feeding material into the jaw crusher. Keep in mind, however, that this will have an adverse effect on particle shape and will also reduce throughput capacity, hindering the crusher’s efficiency.

This scalping of the feed reduces unnecessary wear on the primary crusher. Since scalping the feed reduces the amount of material going into the primary crusher, it also reduces the required size and capacity of the crusher needed. The Wobbler Feeder is especially useful for scalping fines that stick to the larger lumps of material.

A crusher is a machine that uses mechanical energy to break blocks of stone, concrete, or other building materials into smaller blocks of a specific grain size. They are particularly used in the mining industry to reduce the size of ore blocks and facilitate their processing. Crushers are designed to receive blocks of a maximum size.

The facts outlined in the preceding paragraph apply to the action of the crusher on screened feed. We have stressed the desirability of screened feed for all reduction and fine-reduction crushers. If it should be necessary to feed unscreened material to such machines, they should never be choke-fed.

Screening Crusher Feed. The feed to a crusher should not contain an excessive amount of fine material; this could be stated a little more definitely by saying that it should not contain an excessive amount of material smaller than the crusher product size.

Jaw crusher: The material is crushed between a fixed jaw and a mobile jaw. The feed is subjected to repeated pressure as it passes downwards and is progressively reduced in size until it is small enough to pass out of the crushing chamber. This crusher produces less fines but the aggregates have a more elongated form. •
