DetailsA grizzly screen is placed between the magnet and the receiving hopper of the crusher to scalp (remove) boulders larger than the size of the gape. Some mines deliver product direct to storage bins or stockpiles, which then feed the crushers mechanically by apron feeders, Ross feeders or similar devices to regulate the feed rate to the crusher.
DetailsFeeding the Crusher: The cone crusher's feed hopper is filled with raw materials, such as rocks, ores, or recycled concrete, to begin the process. Automated systems or manual labor can be used to accomplish this. The material is subsequently directed by the hopper into the crushing chamber, which houses all of the action. ...
DetailsTable Source: Wikipedia (Crushers) Cone crushers use a spinning cone that gyrates in the bowl in an eccentric motion to crush the rock between the cone surface, referred to as the mantle, and the crusher bowl liner.Gyratory crushers are very similar to cone crushers, but have a steeper cone slope and a concave bowl surface. As the gap …
DetailsBy far the greater number of crusher applications involve feeds which are either graded (a mixture of large, medium, and small particles), or sized to a top dimension well within the effective receiving-opening dimension of the crusher.
DetailsImpact crushers is a versatile crusher that can be used to process natural rock and recycle materials alike. Many people claim that you can't process hard rock with an impact crusher. This is not entirely true because it depends on the breaking characteristics of …

DetailsA crusher is a machine that reduces large rocks into smaller rocks, gravel, or rock dust. Crushers are mainly used in the mining and construction industries, where they are used to break down very large rocks and boulders into smaller pieces. Crushers are also commonly used for jobs like breaking up asphalt for roadwork or demolition projects.
DetailsIn practice, many jaw crushers are fed in this intermittent fashion due to gaps in the delivery of feed material from the quarry. Additionally, jaw crusher feed should be pre-screened using a grizzly screen prior to crushing to remove material finer than the closed-side setting. Setting jaw crushers
DetailsA crusher' surge pocket, sometimes called a "rock box", is found directly below the primary gyratory crusher.It provides limited storage, normally about two truckloads, to enable smooth feeding of crushed product from the bottom of the crusher onto an apron feeder and takeaway belt conveyor.
DetailsThe main characteristic of our jaw gyratory crushers is their enlarged feed opening, which is located on one side of the crusher only. It is normally serrated and, together with the upper part of the mantle, it forms the initial crushing zone. The coarsely crushed material is then reduced to the desired product size in the crushing chamber below.
