==Griding Mill Series==
A grinding mill is a unit operation designed to break a solid material into smaller pieces. There are many different types of grinding mills and many types of materials processed in them. Historically mills were powered by hand (mortar and pestle), working animal, wind (windmill) or water (watermill). Today they are also powered by electricity.

The grinding of solid matters occurs under exposure of mechanical forces that trench the structure by overcoming of the interior bonding forces.
After the grinding the state of the solid is changed: the grain size, the grain size disposition and the grain shape.
Grinding may serve the following purposes in engineering: magnification of the surface area of a solid manufacturing of a solid with a desired grain size pulping of resources

Gyratory [http://www.shibang-china.com/info/Cone_crusher.html Cone crushers] can be used for primary or secondary crushing. The crushing action is caused by the closing of the gap between the mantle line (movable) mounted on the central vertical spindle and the concave liners (fixed) mounted on the main frame of the [http://www.shibang-china.com/info/Jaw_crusher.html crusher]. 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 to rotate around its own axis. The crusher illustrated is a suspended spindle type, meaning that the main shaft is suspended at the top and that the eccentric is mounted above the gear.

==Cone Crusher ==

[http://www.shibang-china.com/info/Cone_crusher.html Cone crusher] is similar in operation to a gyratory crusher, with less steepness in the crushing chamber and more of a parallel zone between crushing zones. A cone crusher breaks rock by squeezing the rock between an eccentrically gyrating spindle, which is covered by a wear resistant mantle, and the enclosing concave hopper, covered by a manganese concave or a bowl liner. As rock enters the top of the [http://www.shibang-china.com/info/Cone_crusher.html Cone crusher], it becomes wedged and squeezed between the mantle and the bowl liner or concave. Large pieces of ore are broken once, and then fall to a lower position (because they are now smaller) where they are broken again. This process continues until the pieces are small enough to fall through the narrow opening at the bottom of the crusher.

==Technology==

For the most part advances in crusher design have moved slowly. [http://www.shibang-china.com/info/Jaw_crusher.html Jaw crusher] have remained virtually unchanged for sixty years. More reliability and higher production have been added to basic [http://crusher.shibang-china.com/Cone_crusher.html Cone crusher] designs that have also remained largely unchanged. Increases in rotating speed, have provided the largest variation. For instance, a 48 inch (120 cm) [http://www.shibang-china.com/info/Cone_crusher.html Cone crusher] manufactured in 1960 may be able to produce 170 tons/hr of crushed rock, whereas the same size cone manufactured today may produce 300 tons/hr. These production improvements come from speed increases and better crushing chamber designs.
The largest advance in [http://crusher.shibang-china.com/Cone_crusher.html Cone crusher] reliability has been seen in the use of hydraulics to protect crushers from damage from uncrushable objects entering the crushing chamber. Foreign objects, such as steel, have been known to cost thousands of dollars of damage to a [http://www.shibang-china.com/info/Cone_crusher.html Cone crusher], and more costs in lost production. The advance of hydraulic relief systems has greatly reduced downtime and improved the life of these machines.
