Applications of Crushers

For example, they break down materials for ore extraction in mining, produce construction materials, facilitate recycling, manage waste, reduce construction waste on-site, aid in cement production, process raw materials in the chemical industry, grind pharmaceutical pills, size raw food in the food industry, and facilitate demolition. Crushers play essential roles in a variety of industries.

1.1, Ore Crushing

A vital stage in the mining process is ore crushing, which is accomplished by utilizing crushers to reduce big rocks and ore chunks into smaller pieces. The huge ore pieces are compressed, struck, or squeezed into smaller granules by crushers using pressure or impact force. The specifications of the finished product and the kind of ore determine the size of these particles. It could be required to perform ore beneficiation processes after the ore has been crushed to the proper size in order to separate the valuable mineral particles and get rid of contaminants. The crushed ore particles are subsequently sent to further processing machinery, such flotation cells and grinding mills, in order to extract and purify more valuable minerals.

1.2, Construction Industry

Crushers are frequently used to handle waste materials from building sites, including bricks, concrete, and gypsum boards. Crushers help reduce waste volume and turn it into recycled building materials by breaking down these waste materials into useful pieces. They are employed in the production of building supplies like asphalt and concrete. Large stone pieces produced during road building are also processed in crushers to provide sturdy and smooth surfaces. Crushers are essential equipment in the demolition of buildings because they reduce the size of structural elements so that they can be transported and processed more easily.

1.3, Chemical Industry

Crushers are used in a variety of ways in the chemical industry, mostly in several areas. Large pieces of raw materials, including chemical feedstocks or ores, must frequently be crushed in the chemical manufacturing process in order to reach the proper particle sizes for later reaction and processing stages. Reactants are prepared in the form of powder or particles using crushers, which guarantees more efficient reactions and more even mixing in chemical processes. Crush raw materials to the right size during catalyst preparation to increase surface area and catalytic activity. Crushers are essential to this process.

1.4, Waste Management

In the realm of waste recycling, crushers are essential in the following ways: they are used to reduce big waste materials—such as plastics, glass, metals, etc.—into smaller pieces. This helps to lessen the amount of trash, which facilitates processing and shipment. Furthermore, crushing garbage into suitable pieces makes further sorting and processing easier to handle, which makes it easier to recover recyclable resources like glass, metals, and plastics. Crushers can be used to crush and process waste that contains hazardous materials, reducing the risk to the environment and facilitating safer management of toxic or dangerous trash in waste treatment facilities. Moreover, crushers may be used to crush biomass waste—such as food scraps and plant materials—into appropriate particles so that biomass energy—such as biogas or biomass fuels—can be produced.

Current Methods of Ore Crushing:

Detonating Blasting:

  • The goal is to break up a lot of rock at the mining location.
  • This is usually the first stage of the extraction procedure. The rock is broken up using explosives to make it simpler to handle and move.

Difficult Crushing:

  • The goal is to reduce massive boulders to more manageable sizes.
  • Description: To further break down the material into finer particles, the broken rock from explosive blasting is put into crushers, usually gyratory or jaw crushers.

Perfect Crushing:

  • Goal: Continue to reduce particle size.
  • Description: To reach a finer size, the material may undergo additional crushing stages utilizing impact or cone crushers after coarse crushing. This is frequently done in order to get the ore ready for further processing.

Grazing:

  • The goal is to get the particles down to a size that is appropriate for mineral extraction or separation procedures.
  • After the ore has been finely crushed, many kinds of mills, including ball mills, rod mills, and autogenous mills, are used to grind it. The ore is ground into a size where valuable minerals may be separated from the trash.
  • In combination, these phases provide a thorough ore processing sequence that gets the ore ready for additional beneficiation procedures. Depending on the kind of ore and the final products that are wanted, these procedures might involve leaching, flotation, or magnetic separation.

The ore dressing equipment provided by MoleDive includes

3.1, Hammer Crusher

The hammer crusher, often referred to as the hammer mill, is a type of crusher that breaks materials with the help of a high-speed revolving hammer. The rotor’s hammer mill receives materials put into it. The materials are broken into smaller bits by the impact force of the hammer and the centrifugal force generated by the revolving rotor.

Hammer crusher operation is based on the impact concept. The material breaks along its inherent cleavage lines or fractures as a result of the hammer’s powerful, kinetic blows.

Utilization:

Mining and Ore Processing: Used in the mining sector, primarily for the primary or secondary crushing of ores (such as gold, copper, and iron ore) and other hard and abrasive materials.

Building Materials: Suitable for pulverizing gypsum, limestone, aggregates, and other building materials.

Coal and Coke Processing: Crushing coal and coke in coal selecting plants.

Benefits:

Compact design, simple construction.

High reduction ratio, appropriate for applications with a lot of capacity.

3.2, Impact Crusher

The counter-attack crusher is a kind of crusher that applies force to entering materials by use of fast rotating hammers or rods. The hammer hits the material, which then collides with the crushing plate and fragments into smaller pieces. The concept of impact, which states that kinetic energy is transferred to the material upon collision, is how counterattack crushers work. The material fractures as a result of this energy along natural cleavage lines or fissures.

Utilization:

For the primary, secondary, or tertiary crushing of different minerals including limestone, coal, ore, and aggregate, mining and quarrying are utilized.

Concrete, asphalt, and other building materials may be crushed with great efficiency.

3.3, Vertical Shaft Impact Crusher

A high-speed rotor with wear-resistant tips is used by the Vertical Shaft Impact Crusher (VSI) to smash materials. The material is supplied into the center of the rotor, where it is broken up into smaller particles by the high-speed rotor’s throw of the material towards a fixed anvil or curtain. Centrifugal force is the basis for the operation of the VSI crusher. The material experiences a kinetic energy imparted by the high-speed rotor, which leads to its inherent cleavage lines or fractures breaking.
