Jaw crushers operate according to the principle of pressure crushing The crushing material is crushed in the wedgeshaped pit between the fixed crusher jaw and the crusher jaw articulated on an eccentric shaft The material is crushed by the elliptic course of movement and transported downwards
Jaw crusher is composed of frame rotating jaw eccentric shaft jaw plate and plate knee etc The motor drives the eccentric shaft through Vbelt making the movable jaw do periodic movement according to the well timed track The material is crushed in this process The frame adopts whole cast steel structure or welding steel plate
As in the jaw crusher maximum movement of the head occurs near the discharge This tends to relieve the choking due to swelling The gyratory crusher is a good example of arrested crushing
There are two basic types of jaw crushers single toggle and double toggle In the single toggle jaw crusher an eccentric shaft is on the top of the crusher Shaft rotation causes along with the toggle plate a compressive action A double toggle crusher has two shafts and two toggle plates
Rocksizer Jaw Crushers Developed by Parker this gives a slight downward movement to the swing jaw that promotes a forced feed and therefore increased output while at the same time minimising any rubbing action resulting in a well shaped product and reduced and even wear on the crushing jaws
1 FEED HOPPER 38 cubic metre hopper Which can be filled by excavator or wheeled loader 960mm opening into jaw crusher Fitted with side support legs
The fixed jaw is an integral part of the crusher frame Both jaws are fitted with manganese jaw liners that can be replaced or reversed when worn During the crushing operation the toggle plate which acts as a pivot point for the jawstock controls movement of the lower part of the swing jaw
A jaw or toggle crusher consists of a set of vertical jaws one jaw is kept stationary and is called a fixed jaw while the other jaw called a swing jaw moves back and forth relative to it by a cam or pitman mechanism acting like a class II lever or a nutcracker The volume or cavity between the two jaws is called the crushing chamber
Types of Jaw Crushers Jaw crushers have been around for nearly 200 years at this point and are one of the most "historic" crusher types Because of this jaw crushers have advanced technologically through the years to make them more durable and to improve their movement to reduce choking and increase operational speed
LippmannMilwaukee jaw crushers are fabricated with an extraheavily ribbed steel plate construction to provide maximum strength and durability while in operation Frames are stress relieved before machining and after welding to ensure the highest quality product
Industrial Rock Crushers employ two planer crushing surfaces set at a small angle to each other and convergent downward One plane is fixed and the other is pivoted either top or bottom allowing a reciprocating motion when pushed by a pitmantoggle arrangement activated by an eccentric drive The 3 common variations of the jaw crusher drive system are describe here
Apr 04 2019· The movement in a jaw crusher may be challenging to prescribe and set up but the developed motion kernel in Rocky DEM allows you to build a model Rocky DEM''s simulation technology enables you to study the workings of the equipment to improve the equipment''s process and integration and make improvements in the prototypes empowering you to develop equipment with more robust
Jaw crushers process medium to hard quarry rock or other materials by compressing it between the fixed jaw and the swing jaw The swing jaw being the moving part is attached to a rotating eccentric shaft The fixed jaw is an integral part of the crusher frame Both jaws are fitted with manganese jaw liners that can be replaced or reversed when worn
Jaw Crusher is widely used to crush materials into medium size in the first crushing process of ore rocks so your rocks would get be ready for the secondary crushing it had a wide range of suitable materials such as granite marble basalt limestone quartz pebble iron ore copper ore and so on the jaw crusher is applicated in mining metallurgy building highway railway water conservancy chemical industry
All LippmannMilwaukee heavyduty jaw crushers feature an oversized heat treated shaft forged of special alloy to provide an exceptionally large eccentric throw These heavyduty shafts are paired with two dynamically balanced flywheels effectively reducing vibration on
Types of Jaw Crushers Jaw crushers have been around for nearly 200 years at this point and are one of the most "historic" crusher types Because of this jaw crushers have advanced technologically through the years to make them more durable and to improve their movement to reduce choking and increase operational speed
The jaw crusher is mainly composed of a frame a movable jaw assembly a movable jaw a fixed jaw a triangular wheel a flywheel a bracket a side guard a discharge port
Jaw crusher movement is guided by pivoting one end of the swinging jaw and an eccentric motion located at the opposite end 4 The size of a jaw crusher is designated by
On the overhead eccentric style Jaw Crusher the moving swing jaw is suspended on the eccentric shaft with heavyduty double roll spherical roller bearings The swing jaw undergoes two types of motion one is a swing motion toward the opposite chamber side called a stationary jaw die due to the action of a toggle plate and the second is a vertical movement due to the rotation of the eccentric
