·replaced reducing wear part related costs even further Metso also develops custom jaws for special applications Special cheek plates are also available Conventional jaw crusher design Nordberg C Series jaw crusher The correct nip angle between the movable and fixed jaw dies ensures
·Taggart expressed the relationship between crusher capacity and reduction ratio in terms of a reduction ton or tonne Q R defined as Q R = Q T ⋅ R 80 where Q T is the capacity in terms of actual tonnage crushed per hour The quantity of feed actually crushed is determined by subtracting the feed undersize from the total quantity of feed
A jaw crusher is a rigorous device manufactured to pulverize rigid substances stones ore and concrete into very small and easy to handle sizes Its structure consists of a pair of jaws one of those is fixed and the other one is free to move and this is the perfect setup for compressing and breaking the materials with absolutely preciseness
On the other hand a jaw crusher has two jaws one fixed and the other movable The material is fed into the chamber between these two jaws and is compressed until it breaks apart They have a higher reduction ratio compared to smooth roll crushers and can handle larger feed sizes When it comes to choosing between a smooth roll crusher
The crushing ratio of a jaw crusher results from the maximum achievable final fineness in relation to the maximum feed size For Retsch jaw crushers this lies between 26 and 220 A high value reflects the capacity of a jaw crusher to accept large sample pieces and provide powerful crushing performance resulting in high final fineness
4 ·The jaw crusher has large crushing ratio which means that jaw crusher can crush large materials over 1000mm into particles smaller than 100mm In crushing and sand production plant jaw crusher is the preferred equipment for coarse crushing of materials with compressive strength not exceeding 320 MPa
·There are several advantages to using a jaw crusher in a crushing operation Some of these advantages include High reduction ratio Jaw crushers are designed to reduce the size of large rocks into smaller rocks or gravel They can achieve high reduction ratios of up to 6 1 which means that a 6 inch rock can be reduced to 1 inch
·Jaw crusher is used as primary crusher it s reduction ratio is usually 6 1 It uses compressive force to break the material this mechanical pressure is achieved by the two jaws of the crusher Inside the jaw crusher is consisting of two vertical jaws installed to a V form one jaw is kept stationary and is called a fixed jaw while the
·Figure Labelled Diagram of Jaw Crusher Working A Toggle and Pitman is the popular mechanism driving the Blake jaw crusher It normally comprises of a pitman working on an eccentric on the crusher shaft and two toggles travelling and traversing like a birds wings one between the main frame and the pitman and the other between the pitman
