Similar to jaw crushers, the mechanism of size reduction in gyratory crushers is primarily by the compressive action of two pieces of steel against the rock. As the distance between the two plates decreases continuous size reduction takes place. Gyratory crushers tolerate a variety of shapes of feed particles, including slabby rock, which are ...

The crushed material moves downward and is continually crushed till it becomes small enough to fall through the gap between the two surfaces. This kind of crusher is used in size reduction of hard and dry solids having size comparatively smaller as in the case of jaw crushers. They can reduce the size of feed by a maximum of about …

Setting jaw crushers. Ideally, the reduction ratio of a jaw crusher should be 6-to-1. There are different ways to calculate reduction ratio, but the best way is something called the P80 factor. The reduction …

Jaw crushers feature safe, simple operation and maintenance. Disadvantages of a Jaw Crusher. Jaw crushers can also have some disadvantages compared to other types of size reduction. Opposing jaw plates are less efficient at reducing materials that are tough, ductile, or soft instead of hard and brittle.

Jaw Crushing. Jaw crushing is typically the most basic means of size reduction — in fact, mining and quarry operations typically have jaw crushers on site, where they are used to reduce large chunks of material to smaller chunks. As the name suggests, this type of mill consists of two jaws, one fixed and one moving.

Jaw Crushers 7 The BB 50 is designed for a very efficient and convenient size reduction pro-cess. The variable speed can be set between 550 and 950 min-1 to adapt the crushing process to sample requirements. The possibility to reverse the rotat- ing direction is helpful if too much sample material has been fed to the crusher causing it to block.

Primary crushers are designed so that the maximum size that can be presented to the crusher is approximately 80% of the gape. Jaw crushers are operated to produce a size reduction ratio between 4 :1 and 9 : 1. Gyratory crushers can produce size reduction ratios over a somewhat larger range of 3 :1 to 10 :1.

Jaw crushers are routinely choke-fed, as this maximises production capacity and ensures particles are uniformly broken. This promotes stone-on-stone crushing, which breaks up flaky or slabbier particles. ...
