introduction to cone crusher
Cone crushers are normally used as a secondary crusher but can be used as a primary crusher if used in processing a sand and gravel deposit. Normally a jaw crusher is used for the initial or primary crushing of larger rocks. To see an illustration of the difference between a standard cone crusher and a shorthead or fine crusher, and to see what the inside of a cone crusher looks like, including an animation of a cone crusher working, go to Cone Crushing. The average standard head cone crusher has an average reduction ratio of 6-10:1. That means an average rock will be fractured into 6-10 smaller rocks after passing through a cone crusher. A shorthead, also known as a fine cone crusher, typically has a 4-6:1 ratio. The maximum size of your target final product will be a good guide to whether you need a standard or fine cone crusher, either as a secondary crusher or a tertiary crusher. Cone crusher capacity is primarily determined by the closed side discharge setting and the diameter of the cone's mantle. Cone crusher capacity will be increased if the maximum final target product size and everything smaller is scalped (removed) prior to being fed into the crusher. The cone crusher's feed chute should be arranged to provide a uniform and consistent amount of feed material so it is distributed evenly around the head and keeps the crushing chamber filled at all times if possible. The size of the cone must match the entire crushing circuit. That means the feed system, scalping system, jaw crusher, cone crusher, and screens must all be designed to work together. Because raw feed consists of various sizes of rocks, a good screening process will enable you to use the smallest crusher while still obtaining the greatest production capacity. That will save you both capital costs and operating costs.used cone crusher cost
Comparing with other kinds crusher,cone crusher with high-efficiency have excellences for fine crushing, high productions and low maintenance.Cone crusher produced by Shanghai MEG definitely occupy the absolute position in China’s machinery area! With simple structure, convenient and reliable operation, convenient maintenance, low operation cost, high reliability, it has been exported abroad and win its own internatioanl welcome and popularity.
