A gyratory crusher is one of the main types of primary crushers in a mine or ore processing plant. Gyratory crushers are designated in size either by the gape and mantle diameter or by the size of the receiving opening. Gyratory 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 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 short-shaft suspended spindle type, meaning that the main shaft is suspended at the top and that the eccentric is mounted above the gear. The short-shaft design has superseded the long-shaft design in which the eccentric is mounted below the gear.
The Crusher is lifted and freed from the spikestrip by Beta Raptor.

You need to pay attention to materials which point at durability on the part of the ice shaver you want to buy. Most common ice shavers are either made of plastic or stainless steels. There is no point in buying an ice crushing machine which does not last more than few months to the date of purchasing and this can be disappointing.
Clean out the low spots by raking away existing gravel. You might also want to make the pothole slightly larger with a pickaxe or shovel. Smaller potholes re-form quickly if not repaired correctly. Widen the hole and even out the surface as best as possible before adding crusher run.

The traditional system of sand production line equipment mainly includes jaw crusher, impact crusher and cone crusher. As the newly-designed sand making machine, VSI crusheris designed to incorporate three crushing types and change feeding methods, which can be used as a crusher machine and a stone shaping machine. VSI crusher not only can accomplish the process of crushing the material, but also can adjust the particle size of gravel aggregate. In sand making process, VSI crusher is widely used for crushing hard and crispy materials, such as rock, grinding material, refractory material, cement clinker, quartzite, iron ore and concrete aggregate. The advantages of VSI crusher mainly reflected in the proportion of fine product and product of cubic shape is increased distinctly and product of lump size is decreased by a large extent.
Dewatering screens have a wide variety of applications, including dewatering, desliming, degritting, rinsing, scrubbing and washing.
Iron is a kind of metals that is found the earliest in the world, the most widely used, and the most dosage. Its consumption accounts for about 95% of total consumption of metal. Iron ore is mainly used for smelting different cast iron (carbon content is in commonly 2% above) and steel (carbon content is in commonly below 2%)in iron and steel industry. Iron and steel products are widely used in various departments. It is necessary to social production and the public life of basic materials.
