  Gyratory Crusher Overview

  A gyratory crusher is among the main kinds of primary crushers in a mine or ore processing plant. Gyratory crushers are designated in dimensions either by the gape and mantle diameter or from the size the receiving opening. Gyratory crushers can be utilized for primary or secondary crushing. Because, the gyratory crusher design is broken product quality and production capacity as the primary factor to consider. Gyratory crusher is developed for both dry and wet crushing of brittle, medium-hard materials for the mining, cement, coal, metallurgic material, construction material, road building, and petroleum & chemical industries.
• Application area:mining, cement, coal, metallurgic material, construction material, road building, and petroleum & chemical industries
  Processing stage: primary and secondary crushing
  Crushing material: limestone, gypsum, talcum, coal, calcite, bauxite, granite, slag, iron ore etc. (<Moh’s harness 9)
  Crushing ratio: 5
  Main components: Step bearing, ShellPinion shaft, Mantle, Main Shaft Sleeve, Main Shaft
  Working principle: the gap between movable cone and fixed cone changes with the rotation of main shaft, thus the material is squeezed to the required size
  Discharge opening: 150mm~170mm
  Capacity: 720t/h~815t/h

Gyratory Crusher Detail Info

• Gyratory crusher application

  Gyratory crusher is mainly used to crush hard and medium hard stones in stone mining, metallurgy industry, building material, highway, railway, chemical industry, etc. The highest anti-pressure strength of material to be crushed by small jaw crusher is 320 Mpa.

• Gyratory crusher main features and benefits

  • 1. Optimum crushing ratio.
  • 2. Starts under load possible.
  • 3. Main Shaft Assembly and crusher parts designed to assure security.
  • 4. Forged alloy gears and carburized pinions engineered to prevent tooth failure.
  • 5. High capacity lubrication for smooth operation.
  • 6. Automation systems are available for all the models of gyratory crushers.
  • 7. Low power requirement, low maintenance and operating cost.

• Gyratory Crusher Working Principle

  Gyratory crusher is similar in basic concept to a jaw crusher, consisting of a concave surface and a conical head; both surfaces are typically lined with manganese steel surfaces. The inner cone has a slight circular movement, but does not rotate; the movement is generated by an eccentric arrangement. As with the jaw crusher, material travels downward between the two surfaces being progressively crushed until it is small enough to fall out through the gap between the two surfaces.
  Gyratory crusher consists of a long spindle with attached hard steel conical grinding element. The spindle is suspended at the top by a "spider" and the bottom end is seated in an eccentric sleeve. The eccentric sleeve rotates and causes the spindle to move in a conical path within the fixed outer crushing chamber. This closing of the gap of the grinding element and the fixed surface generates the crushing action. Material that has been reduced to the desired size, falls through the opening of the gap at the bottom of the grinding element.
  Gyratory crusher is designated in size either by the gape and mantle diameter or by the size of the receiving opening. 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.
