Jaw Crusher technology RETSCH Jaw Crushers are robust and powerful forced-feed crushers. The feed material passes through the no-rebound hopper and enters the crushing chamber. Size reduction takes place in the wedgeshaped area between the fixed crushing arm …
Primary crushing with jaw crushers. In terms of the size of the feed opening, the client gets a better return on investment when the primary crusher is a jaw crusher. That means less drilling and blasting because the crusher accepts larger boulders.
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 × …
Jaw crushers find a wide application for brittle materials. For example, they are used for comminution of porous copper cake. A Fritsch jaw crusher with maximal feed size 95 mm, final fineness (depends on gap setting) 0.3–15 mm, and maximal continuous throughput 250 Kg/h is shown in Fig. 2.8.
A larger feed opening increases material intake and ensures that the rocks enter the jaw crusher’s cavity without restrictions. A steeper nip angle decreases operating costs by reducing wear on jaw dies and speeds up material flow down in the cavity.
That crusher must be capable to reduce the size of even the lastest rocks it is fed. To secure the capacities specified, all feed to crushers should be smaller than the feed opening of the crusher in at least one dimension. The crusher discharge P80 product size needs to remain less than 1/3 of the related conveyor belt width.
Compared with the jaw crusher, the feeding size of the rotary crusher is larger, the discharging size is smaller and more uniform, and the content of needle-like particles in the discharging is less than 10%. the raw material can directly into the feed mouth without the need for a feeder.
Thesizeof ajaw crusheris usually described by the gape and the width, expressed as gape × width. The commoncrushertypes, sizes and their performance are summarised in Table 4.1.Currently, the dimensions of the largest Blake-typejaw crusherin use are 1600 mm × …
As a rule,Jaw Crushershave a 6:1 or 8:1 ratio for crushing material. Still using the 32 x 54Jaw Crusherexample, the topsizeof thefeedentering the crushing chamber has to follow the F80 rule that 80% of the topsize feedmaterial is smaller than the gape opening.

Thus, one of the first things you'll need to check before buying is the maximumsizeof the rock sheet you canfeedinto thejaw crusher. Generally speaking, purchasing one a little wider than you need is a good idea, as it will allow you to easily accommodate exceptions.

May 13, 2019· Additionally,jaw crusher feedshould be pre-screened using a grizzly screen prior to crushing to remove material finer than the closed-side setting. Settingjawcrushers. Ideally, the reduction ratio of ajaw crushershould be 6-to-1. There are different ways to calculate reduction ratio, but the best way is something called the P80 factor.
PEJaw Crusher Jaw crusheris used for crushing all kinds of ores and rocks with compressive strength below 320MPa. It is generally used for primary crushing of materials. The machine is widely used in mining, building materials, metallurgy, electric power, water conservancy, transportation and many other fields. 0086-371-63769782
