A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials as in rock ore, so that pieces of different composition can be differentiated.
Essentially, the gyratory crusher consists of a heavy castiron, or steel, frame which includes in its lower part an actuating mechanism eccentric and driving gears, and in its upper part a coneshaped crushing chamber, lined with wearresisting plates concaves.Spanning the crushing chamber across its top is a steadyrest spider, containing a machined journal which fixes the position of
Gyratory crushers are principally used in surfacecrushing plants. The gyratory crusher Figure 6.5 consists essentially of a long spindle, carrying a hard steel conical grinding element, the head, seated in an eccentric spindle is suspended from a spider and, as it rotates, normally between 85 and 150 rpm, it sweeps out a conical path within the fixed crushing chamber, or
The gyratory crushers are equipped with a hydraulic setting adjustment system, which makes it possible to regulate the gradation of the crushed material. Cone crushers . Cone crushers resemble gyratory crushers from technological standpoint, but unlike gyratory crushers, cone crushers are popular in secondary, tertiary, and quaternary crushing
As an example, suppose that it is required to make a reduction of 71 in two stages of crushers, one a standard gyratory and the other a finereduction crusher. We know from our examination of the crushing characteristics of these types that, for equal reduction ratios, the volumereductionratio in the standard gyratory is considerably higher
The AllisChalmers Type R Small Gyratory Reduction Crusher is designed for large capacity, fine crushing and incorporates many improvements over other gyratory type crushers previously manufactured by this company. The most distinctive feature of the Type R Crusher is the builtin, oil filled hydraulic jack used for fast, positive change of crusher setting while crusher is operating.
The first important development in the move to adapt the gyratory crusher to fine crushing was the debut of the Superior McCully finereduction crusher, which was brought out a few years before AllisChalmers took over these crushers. This machine was designed along lines identical to those of the standard Superior McCully crusher with one important exception instead of the orthodox tapered
Crushers may be divided into three general classes, with respect to the manner in which they do their work Pressure Crushers This category embraces the several types of gyratory crushers and jaw crushers, as well as the double crushing rolls, with either smooth or corrugated shells. Impact Crushers This division is represented chiefly by the various styles of hammermill also by the cage
Gyratory crushers can produce size reduction ratios over a somewhat larger range of 31 to 101. The primary operating variable available on a crusher is the set and on jaw and gyratory the openside set OSS is specified. This reflects the fact that considerable portions of the processed material fall through the crusher at OSS and this
History of crushers. Crushing and breaking of rock, ore and minerals is one of the oldest industries undertaken by man. The earliest crushing known was by hand on 34native34 ores gold, silver, and copper or on ores containing lapis lazuli, garnet, diamond, jade, etc. Glass making may have required breaking of agglomerates.
Mechanical Reduction Methods. There are four basic ways to reduce a material by impact, attrition, shear or compression and most crushers employ a combination of all these crushing methods. Compression. As the name implies, crushing by compression is done between two surfaces.
Gyratory equipment, used in mechanical screening and sieving is based on a circular motion of the machine. Unlike other methods, gyratory screen operates in a gentler manner and is more suited to handle fragile things, enabling it to produce finer products. This method is applicable for both wet and dry screening.
Metso39s product family of primary gyratory crushers is called Superior MKIII primary gyratory crushers. The MKIII stands for the third generation of the Superior primary gyratory crushers Metso has developed during over 100 years in designing and manufacturing crushers.. The latest Metso Superior MKIII primary gyratory crushers generation is again better, more efficient, safer
Stationary gyratory crushers. CG850i Gyratory crusher CG830i Gyratory crusher CG820i Gyratory crusher CG810i Gyratory crusher Plant solutions The onepiece spherical spider bearing offers at least 5 times longer wear life than than previous Sandvik crushers. High reduction, great capacity.
Size Reduction Machine. Viridis provides robust and efficient machine that perform size reduction of solid particles which comply with clients requirements particle size reduction machine includes click the equipment below to read respective working mechanismsball mill semiautogenuos grinders crusher jaw crusher cone crusher gyratory crusher roll mill ball mill the ball mill.
Additionally, jaw crusher feed should be prescreened using a grizzly screen prior to crushing to remove material finer than the closedside setting. Setting jaw crushers. Ideally, the reduction ratio of a jaw crusher should be 6to1. There are different ways to calculate reduction ratio, but the best way is something called the P80 factor.
