the right jaw design can make a big difference for your jaw crusher. our customers have proven that the right jaw plate design can make a dramatic difference, depending on the application. We have many case histories in which wear life increases of 50% are common, and some in
jaw crushers are often designated by the size of the top opening where material enters. the openings tend to be either rectangular or square and are referenced in inches. for example, a 3244 or jaw crusher has a by opening, being the gap at the top between the jaw dies and being the width between the side plates.
working of the crusher is as under. the main shaft of the crusher is journaled in the spider bearing and in the eccentric bearing assembly. the spider bearing fixes the position of the upper end of the main shaft. eccentric bearing assembly with inner bushing can be replaced, or in some models turned, to adjust the stroke.

jaw crushers are mainly used as primary crushers. their main purpose is to reduce rocks to smaller sizes for the next crushing stages. jaw crushers are a popular alternative to primary gyratory crushers, since they can process large amounts of hard material efficiently. due to their smaller physical size, jaw crushers are also ideal for tight spaces, such as underground mining and mobile
the sag mill was designed to treat 2,065 of ore at a ball charge of volume, total filling of 25% volume, and an operating mill speed of 74% of critical. the mill is fitted with mm grates with total grate open area of 7.66
the differential pressure between the inlet and outlet of the mill is an important process variable for the testing of grinding aids.p mill reflects the load and the filling level of the mill. At unchanged separator settings, the increase of mill indicates more internal circulations and more fines. As a result of the higher mill, the mill vibration increases (ms
