Reducing tons of massive raw materials to useable product takes a heavy toll on bearings, seals and other crusher components. Shock loads and high vibration, plus exposure to dust, dirt and the elements can lead to bearing overload, contamination and lubricant loss. Eventually, premature failures, costly shutdowns and lost productivity follow.

92 Double toggle jaw crusher Double toggle jaw crushers have a large mouth open-ing. They are used, for example, as primary crushers to prepare ballast for road building. The coarse crushing is followed by further crushing operations until an ag-gregate of the size and shape required, e.g. gravel or grit, is obtained. Operating data
How you select your primary crusher will be based on factors like moisture content, maximum rock lump size, material density SG, abrasion index, degradability and it being prone to dusting or not. The crusher capacities given by manufacturers are typically in tons of 2,000 lbs. and are based on crushing limestone weighing loose about 2,700 lbs. per yard3 and having a specific gravity of 2.6.

TYPES OF CRUSHERS As stone passes through a crusher, the reduction in size may be expressed as reduction ratio. The reduction ratio is the ratio of crusher feed size to product size. The sizes are usually defined as the 80% passing size of the cumulative size distribution. For jaw crusher, the ratio can be estimated by the gape. CHAPTER 14.

to uniform size and shape so that the materials can be baled up according to the size of the crushing bin. The uniform size and shape of the materials can be obtained by providing a bin onto which the material is to be crushed. The crusher is designed to operate by both mechanical and electrical means.
Roll Crusher Applications. Roll Crushers are simple in design and construction, long-lasting, economical, and versatile. Roll crushing surfaces operate at a fixed distance apart, as opposed to the continually changing distances in a jaw or cone crusher. Product size is much more consistent. Both oversized pieces and fined are minimized.
