Jaw crushers are one of the two classes of primary crushers and consist of a heavy main frame carrying a stationary fixed jaw and a pivoted, swing jaw. The swing jaw can be pivoted at the top (Blake crusher) or at the bottom (Dodge crusher), and is given an oscillating motion by means of toggles and a pitman riding on an eccentric shaft.Web

Table Source: Wikipedia (Crushers) Cone crushers use a spinning cone that gyrates in the bowl in an eccentric motion to crush the rock between the cone surface, referred to as the mantle, and the crusher bowl liner.Gyratory crushers are very similar to cone crushers, but have a steeper cone slope and a concave bowl surface. As the gap …Web

Double-Roll-Crusher Sticky and soft materials are reliably crushed in 2 or 3 stages down to the required product size. Due to the low crushing ration, the thyssenkrupp Double-Roll-Crusher is producing a product size ditribution with less content of fines and therefore it is the most suitable machine for the lime-industrie.Web

How a Jaw Crusher works. Reduction Ratio of Sampling Jaw Crushers. Jaw Crushers typically have a crushing ratio of 6:1, though there are a number of high efficiency Jaw Crushers available that can produce smaller crushed product sizes with higher crushing ratios (possibly as high as 8:1 or 10:1), albeit at lower feed rates.Web

Jaw crushers are normally capable of a reduction ratio of 1:2 or 1:3. This ratio is afected by the feed material's bulk density, crushability, size distribution and moisture content – …Web

The reduction ratio is then calculated by comparing the input feed size passing 80 per cent versus the discharge size that passes 80 per cent. The finer the CSS, the greater the proportion of fines produced. The CSS of a jaw crusher helps determine the nip angle within a chamber, typically 19 to 23 degrees.Web

The capacities are based on the crusher receiving full, continuous feed of clean, dry, friable stone weighing 100 lb/cu ft. These capacity tables show several significant differences between the two common types of primary crushers. A jaw crusher has a wider range of settings—generally, a maximum of two to three times the smallest setting.Web

Under this concept, fuel elements are crushed to ring-size particles smaller than 3/16 in. (4.8 mm) while minimizing the breakage of TRISO-coated fuel particles.

Jaw crusher limitations. Jaw crushers typically produce less fine material than impact crushers. A jaw's reduction ratio is approximately four to one, and a jaw crusher is commonly used as a primary crusher for initial size reduction or to produce non-spec material. However, fines are required to meet specific gradations and increase …Web
