jaw crushers. jaw crushers are often used as primary crushers and are perhaps the most popular crusher worldwide. these compressive crushers are suitable for most any type of material.in this type of crusher reduction takes place between a stationary jaw plate and a moving jaw plate.
westpro’s heavy-duty jaw crushers are available as standalone units portable assemblies and as modular crushing units. generally used as primary crushers these mine-duty jaw crushers provide excellent coarse material crushing performance in the mining and aggregate industries.
the size of a jaw crusher is usually described by the gape and the width expressed as gape × width. the common crusher types sizes and their performance are summarised in table 4.1. currently the dimensions of the largest blake-type jaw crusher in use are 1600 mm × 2514 mm with motor ratings of 250 300 kw.
in the standard gyratory crusher this is accomplished very simply by increasing the thickness of the concaves at the top and tapering them down toward the discharge; in the jaw crusher the change is generally made by inserting a wedge-shaped filler behind the liner plates on the movable jaw.
single toggle jaw crusher is generally used where size distribution is not of paramount importance but productivity is to be maximized with lower power consumption. these do not require high operating skill and gap setting is simpler.
generally speaking the jaw crushers are usually used as the primary crusher or secondary crusher in the reduction system of crushing circuit that may consist of several stages and crushers. types of jaw crushers: immovable two portable crushers of wheel type and track type.
fixed jaw crusher as a coarse crushing machine has larger discharge size generally in 300-350mm depending on the manufacturer and product model . impact rock crusher as a medium or fine crushing machine obviously has a smaller larger discharge size.
jaw crusher is mainly used for all kinds of ores and medium size bulk materials broken can be broken compressive strength is not more than 320mpa materials divided into coarse crushing and fine crushing.
jaw crushers typically use spherical roller bearings chosen for their ability to manage high radial loads and the presence of misalignment. spherical roller bearings self-align and thus better compensate for shaft deflections and seat misalignment.
as a kind of primary fracture jaw crusher has a wide range of applications complex materials and relatively harsh working environment. therefore more jaw materials are needed to adapt to different working conditions which is the best working condition of the seesaw.
jaw crusher machines are most commonly categorized depending on the width of the feeding chamber and are divided into large medium and small. also jaw crushers can be classified into simple complex and combination swings depending on the motion characteristics of the two jaw plates.
c120 jaw crusher is generally used as primary crusher as the first step of size reduction. it prepares the feed for the secondary crusher in a crushing and screening process. however due to its versatility c120 jaw crusher can be utilized in later stages of the crushing process as well depending on the application and processed material.
