How do you pick a mobile crusher that’s right for your company?

Must read

A crusher is a device that transforms large stones, chunks of concrete, or other building materials into smaller ones with a predetermined grain size using mechanical energy. They are mainly utilized in mining to shrink ore chunks and speed up processing. Blocks of a specific maximum size can only be put into crushers. To get the required end product, it may be necessary to go through many crushing procedures.

Mobile stone Crusher in India are categorized according to how finely they break up the raw material. There are primary, secondary, tertiary, and quaternary crushers (which produce coarse final products) (fine particle finished products).

Types of mobiles stone crushers in India

The application and feed material are the first and most important factors. There are many different crushers, each designed to fulfil the needs of a particular application or set of materials. The degree of hardness of the feed material is the most crucial consideration.

Compressive strength, or the maximum force a material can withstand before breaking, is a common way to describe a substance’s hardness. For ores and other hard materials, the hardness ranges from 7000 psi for concrete to 50,000 psi.

The longer it may take to crush a substance, the more complex the material is. The particular crusher for the operation will depend on the degree of hardness in addition to production timeframes.

  1. Jaw Crusher– The jaw crusher is used mainly to break rocks and other hard, abrasive materials like granite, ores, and recycled concrete. The rock is trapped and crushed between the jaws, which are made of fixed and swing plates. The moveable jaw is rotated by an eccentric shaft that receives action from a motor and a belt. This moving jaw is returned by a spring, allowing the crushed materials to enter the crusher gradually. When the materials are tiny enough, they drop between the crusher’s two jaws. The crusher reduces the rock to small stones, which is particularly useful in producing concrete for buildings and roads.

Jaw crushers employ a simple and dependable technology that doesn’t need any upkeep or engineering expertise. They are the most often used crushers worldwide. When the main goal is to break up massive blocks into smaller bits that other machines can then process, jaw crushers are exceptionally well suited.

Pros:

  • Low operating and maintenance costs because there aren’t many moving parts.
  • Brings the raw material down to roughly 150 mm.

Cons

  • Not appropriate for tiny material requirements (less than 150 mm) (smaller than 150 mm). It can be used in conjunction with other crushers to produce grains of a smaller size if necessary.
  • Handling clay or metal mixed with rock is not recommended.
  • Cone Crusher: Cone crushers, commonly called conical crushers, shatter rock in a bowl between an eccentric revolving head. A wear-resistant mantle protects the rotating head from the elements. Once between the two jaws, the vast chunks are split into smaller pieces that can fit through the small aperture at the bottom of the breaking chamber before slowly descending into the crusher to finish the process. Rocks ranging in hardness from medium to soft can be crushed in a cone crusher.

Pros:

  • dependable construction
  • extremely productive
  • simple correction
  • Low operating expenses This particular type of crusher has a spring release mechanism that guards it against overloads and enables incompressible materials to flow through the crushing chamber without causing damage to the machine.
  • affordable machine

Cons:

  • All types of material cannot be fed into the cone crusher. For the crusher, the materials must be dimensioned beforehand (usually 200 mm or less).
  • The completed product lacks homogeneity, which is crucial for many material requirements.
  • Handling clay or metal mixed with rock is not recommended.
  • Impact Crushers– Horizontal impact crushers are perfect for contaminated materials and can readily handle any clay, dirt, or metal mixed in with the feed material. They were developed to fill the void left in the market by cone and jaw crushers. For mixed materials, impact crushers are the best option. When metal, such as reinforcing bars, wire mesh, or anchors, is combined with the feed material, it can crush clay, dirt, or metal. Although they may smash hard materials, they work best with mild to medium-hard rocks. Impact crushers, often known as hammer crushers, can have either a vertical axis or a horizontal shaft.

Pros:

  • Impact allows for better size control of the crushed product, such as better cubic gravel.

Cons:

  • Operating expenses can be more significant.
  • It may be challenging to shatter small pieces since the crusher’s capacity to split blocks depends on the amount of energy the stone has acquired upon collision with the hammer. As a result, this energy is dependent on the stone’s mass and the hammer’s speed.
  • The stuff being crushed affects how quickly the beaters wear out.

How should I pick the suitable mobile stone crusher for my company?

There are numerous qualities to take into account:

  • The hardness and abrasiveness factor. It is crucial to know the material that will be crushed, especially its abrasiveness and hardness. Before breaking, you must assess the material’s compressive strength or the most significant force it can withstand.
  • The measurements. It would be best to consider the machine’s maximum allowable dimensions (length, width, and thickness).
  • Requirement for granulometry. The desired outcome, or the grain size after crushing, must be specified.

You must ascertain the processing throughput (or capacity) required for your use. Tonnes/hour are used to measure this. If you are looking for a mobile stone crusher of the best quality, look no further than E-track.
