Stone crusher for soft or medium hard and extremely hard materials crushing, plastic, widely used in a variety of ores, cement, refractories, aluminum where the soil clinker, emery, glass raw materials, mechanism building sand, stone and various metallurgicalslag, especially for silicon carbide, carborundum, sintered bauxite contour hard, special hard and corrosion-resistant materials is higher than other types of crushers yield efficacy.
Primary Crushers
Primary crushers that are heavy duty, just like the crushers in the Philippines, can crush a ROM ore. Under Primary crushers are the Jaw Crushers and Gyratory Crushers.
Jaw Crushers: This equipment utilizes compression force when reducing the size of materials. Its processing speeds range up to 100-350 rev/min.
The materials used for the components of this crusher are made from cast steel replaceable liners made of Iron or Manganese Steel.
Jaw crushers are classed based on their receiving areas like the width of the plates and the gap between the jaws and opening.
Gyratory Crusher: This crusher has a long spindle and a conical grinding equipment made of steel. Normally, a Gyratory Crusher revolves between 85 and 150 rev/min in a conical path.
Its outer casing is constructed from heavy steel casting or plates. Then, these metals are fortified with reinforced alloyed white cast-iron.
Secondary Crushers
Secondary Crushers can only manage to break down medium size rocks. There are five categories of crushers that fall under the description of a Secondary Crusher.
Cone Crusher
In terms of operation, a cone crusher is similar to a Gyratory Crusher. The distinction between the two is the lesser steep crushing chamber and more parallel crushing zones of a Cone Crusher, and the spindle in a Cone Crusher is supported, not suspended like the ones in a Gyratory Crusher.
Impact Crusher
Just like what the name states, Impact Crushers utilize impact for its process, compared to other crushers that use pressure.
Hammer Mill
Staying true to its name, a hammer mill crushes fragile stones against a rotating hammer. Before, the hammers used were made of Manganese Steel. It was later on changed to nodular cast Iron that contains Chromium Carbide, making the hammer strong against abrasions.
