Wearing parts in the gyratory crusher may be either chilled cast iron or manganese steel, depending on the character of the material to be crushed and the particular class of service for which the machine is intended. Standard crushers, in the small and medium sizes, are customarily fitted with chilled-iron head and concaves for …

Jaw crushers are commonly used in the mining and aggregate industry for breaking down different types of materials, such as rocks and minerals, into smaller pieces. There are several types of jaw …

As a matter of fact, when the crusher setting and other conditions are such that the machine is operating at anything approaching a choke condition, wear is very rapid in the region of the discharge point, as compared to the rest of the chamber so much so that "belling" of the head, and "dishing" of the concaves is likely to progress to ...

the fixed concave liners mounted in the top shell of the crusher. The gap is opened and closed by an eccentric assembly in the bottom shell, which causes the central vertical shaft to gyrate. The vertical shaft is free to rotate about its own axis. Gyratory crushers are one of the main primary crusher types used in mines and quarries.

A short-head cone crusher has a short crushing chamber and it is designed for the production of finer output sizes, generally between 6 mm and 25 mm. A fine cone crusher, also known as a tertiary cone crusher, is used for the production of They are manufactured to produce very fine output sizes, mostly below 6 mm.

But, viscous materials will cause a cone crusher to jam. Further, how much material the machine can handle differs. With a jaw crusher, the material must be evenly fed into the crusher, and the …

3 ⚫ The gap is opened and closed by an eccentric on the bottom of the spindle that causes the central vertical spindle to gyrate. ⚫ The vertical spindle is free torotate around its own axis. ⚫ The crusher illustrated is a short-shaft suspended spindle type, meaning that the main shaft is suspended at the top

motion of the eccentric causes the main shaft, which is free to rotate around its own axis, to rotate slowly in the same direction as the travel of the eccentric when the crusher is empty and in the opposite direction when the crusher is working. The older long-shaft gyratory crusher which has the gear above

Gyratory crushers typically crush to reduce the size of aggregate to a maximum of about one-tenth of its original size. Gyratory crushers are always installed vertically orientated. A gyratory crusher's size is classified by: Its gape and mantle diameter. The diameter of …

Crusher Reduction Ratio I have mentioned the fact that, as the % of voids in the crushing chamber decreases, the production of fines by attrition increases. This is like saying that, as the Crusher Reduction Ratio in any given crusher is increased, the % of fines in the product will increase, even though the discharge setting remains unchanged.
