Understanding the Different Types of Ballast Crusher Machines Available

Ballast refers to the stones or sand placed beneath the railway tracks. They serve the purpose of providing stability to the track structure, ensuring that the tracks remain in place and do not move, even under heavy load. In order to accomplish this, ballast crushers are employed to break down the stones into smaller pieces to be used as a sub-base material under the railway tracks.

There are different types of ballast crusher machines that are designed to vary in their size and power requirements. It is important to choose the right machine that meets your requirements. To understand the different types of crushers and to know which type of crusher is suitable for your specific needs, read on.

Jaw Crusher

Jaw crusher is a heavy-duty machine that crushes hard materials. So its hence muse be robustly constructed. Crusher frame is made from steel or cast iron. The jaws are made of cast steel. The liners are made from“Ni-hard,” Ni-Cr alloyed cast iron or manganese steel which can replaceable and use to reduce frame wear. The cheek plates are also made from hard alloy steel and installed to the sides of the crushing chamber to protect the frame from wear. Due to its large mouth opening, jaw crusher is able to handle quantities of rock or ore with a high degree of compression. Jaw crusher is widely used in the fields of mining, railway construction, water conservancy project, metallurgy, chemical, building material industries.

Cone Crusher

Cone crusher is a powerful machine that is commonly used for crushing hard and highly abrasive mines such as granite, basalt, andesite and stream material. The cone crushers crush the materials by pressing and are used as a premier, secondary or tertiary crusher. Since processing very hard mines and rocks, they are ideal for producing road base, top dressing chips, manufactured sand, and more.

Roll Crusher

Roll crushers are a compression-type reduction crusher with two drums rotating about a shaft. The gap between the drums is adjustable. The particles are drawn into the crushing chamber by the rotating motions of the rolls and a friction angle is formed between the particles and the rolls. The stone fractures from the compression forces presented by the rolls as they rotate. The crushed particles are then forced between the rotating surfaces into the smaller gap area. Roll crushers are mostly used in smaller scale production to crush ores that are not too abrasive. This type of rock crushing equipment gives a very fine product size distribution with very little dust production.

Impact Crusher

Impact crushers do not use force to crush materials, instead, they use impact. The material is contained within a cage that has openings on the bottom or side to allow for the crushed materials to escape. Impact crushers can be classified into two categories: vertical shaft impact crushers (VSI) and horizontal shaft impact crushers (HSI). VSI crushers use high-speed rotors with wear-resistant tips, and a crushing chamber designed to 'throw' the rock against. HSI crushers are used to crush hard materials like granite, basalt, and hard concrete.

Knowing the different types of crushers and how to choose the most appropriate one will ultimately help you complete your project on time and within budget.
