Mining Industry Crushing Machine

What are the machines for crushing stones in the mining industry?

The crushing operation is an important part of mining, and it is the prerequisite for continuous and good follow-up operations such as milling and beneficiation. According to the engineering requirements and the characteristics of the ore itself, selecting the appropriate crusher can improve the project work efficiency, obtain better processing results and large economic benefits. The crusher for mining can be divided into: jaw crusher, hammer crusher, impact crusher, composite crusher, roller crusher, impact crusher and so on.

Mining Industry Crushing Machine
  1. Jaw Crusher: The jaw crusher has the characteristics of large crushing ratio, uniform product size, simple structure, reliable work, easy maintenance and economical operation.
  2. hammer crusher: (ring hammer crusher) referred to: hammer broken, mainly suitable for crushing minerals of various brittle materials. The materials to be crushed are coal, salt, white Asia, gypsum, alum, brick, tile, limestone and the like.
  3. Impact crusher: referred to as counter-breaking, it is suitable for crushing medium and hard materials, such as limestone crushing in cement plant, which has the advantages of large production capacity and small particle size.
  4. composite crusher: abbreviation (composite broken) is suitable for building materials, mining, metallurgy, chemical industry, broken limestone, clinker, coal and other ores. Features: large production capacity; high crushing ratio, low energy consumption; good sealing, stable operation; easy maintenance.
  5. roller crusher: the roller crusher (roller crusher, roller crusher) for ore dressing, chemical, cement, building materials and other industrial sectors in the crushing and fine crushing of various medium hardness below the ore and rock .
  6. Impact crusher: Also known as sand making machine, it is widely used in various kinds of hard and brittle materials such as rock, abrasive, refractory material, cement clinker, quartz stone, iron ore, concrete aggregate, etc. Finely crushed (made sand). The series of impact crushers (sand making machines) are suitable for construction sand and gravel for road construction.

The crusher is a key equipment in the mining, metallurgy, coal, building materials and other industries. At present, there are many crushing equipment commonly used in mines, such as jaw crusher, cone crusher, hammer crusher, gyratory crusher and so on. In actual production, in order to ensure the normal and stable operation of the crusher, the foundation of the crusher must be properly designed. The basic design method of the crusher is described below.

When designing the crusher foundation, the following information should be collected:

  1. Basic model, speed, specifications, weight, center of gravity position and contour size;
  2. The power and transmission mode of the machine;
  3. Outline drawing of the machine base, auxiliary equipment, pipe position and position and dimension drawings of pits, grooves and holes;
  4. Anchor bolts, the size and position of the embedded parts, and the thickness of the secondary grouting layer;
  5. The planar position of the foundation;
  6. Engineering geological survey and hydrogeological data of the construction site;
  7. The value of the dynamic load (ie, the disturbance) of the crusher, the position of the action, and the mass moment of inertia of the machine.
