·crushers need a choke feed to utilize rock on rock crushing And to main tain a choke feed the crusher must have the correct liner for the feed material If coarse material is fed to a cone with a fine liner the liner will wear unevenly near the top of the man ganese A feed that is too coarse will also result in low tons per hour a
4 ·One method that has been used to model mining equipment is the discrete element method DEM which has proven to be an excellent tool for predicting the behavior of mineral processing machines This process is repeated and simulates how particles move and interact in the domain The DEM models of crushers allow a robust analysis of
Feeding Jaw Crushers It is desirable to feed jaw crushers continuously However feed is often provided intermittently using front end loaders shovels or trucks When the feed rate exceeds the product rate the condition is known as choke feeding In choke feeding particle breakage occurs between the plates and particles and between the
·The feeding process marked in red 1 in Fig 1 is equipped with belt conveyors magnetic separators screens and coal crushers The ring hammer crushers are assembled between B 2 and B 3 It can be seen from Fig 1 that most of the conveying devices are redundantly configured for safety purpose

·For these distinctive needs different types of crushers bring optimal results This can be easily achieved by using a stockpile or a silo to regulate the inevitable fluctuation of the feed material flow Level monitoring devices detect the maximum and minimum levels of the material starting and stopping the feed of material to the crusher
·As experience shows when one determines the energy power parameters of crushing and grinding processes by using the existing methods the power of motors used in drives of existing crushers of various types often turns out to be excessive [10 11] In this case the drive will operate at a relatively low load ratio of the power consumed by the working body

·Normally belt conveyors are used to feed the ore to the crushers When the material is moved on conveyors through chutes and in bins segregation occurs immediately Quist and Evertsson 2010 The most widely utilized method is the integration of discrete element method DEM and computer aided design CAD tools Kessler and Prenner
·Wearing parts in the gyratory crusher may be either chilled cast iron or manganese steel depending on the character of the material to be crushed and the particular class of service for which the machine is intended Standard crushers in the small and medium sizes are customarily fitted with chilled iron head and concaves for crushing soft and medium
·Perhaps the first and most fundamental aspects to consider are application and feed material A variety of crushers exist and each is tailored to meet the demands of very specific applications or materials The most critical factor with feed material is its degree of hardness Sean Donaghy is the national UK sales manager for IROCK Crushers
