Types of Crushers

Crushers are machines used to reduce the size of solid materials, including rocks, ores, and other bulk materials, for various industrial applications. There are several types of crushers designed for specific purposes and materials. Here are some common types of crushers:

Jaw Crusher: A jaw crusher is one of the most common types of primary crushers. It uses a pair of jaws to crush material by applying force to it. The material is fed into the top of the jaws, and it is progressively crushed as it moves down through the crusher until it's small enough to pass through the gap between the two jaws.

Gyratory Crusher: A gyratory crusher is similar in basic concept to a jaw crusher but has a cone-shaped gyratory motion. Gyratory crushers are typically used for large primary ore crushing.

Cone Crusher: Cone crushers are used for secondary and tertiary crushing. They have a conical-shaped chamber and an eccentrically rotating mantle that gyrates within the fixed bowl. The material is crushed between the mantle and the bowl liner.

Impact Crusher: Impact crushers, also known as impactors or horizontal shaft impactors (HSIs), use the principle of rapid impact to crush materials. They are often used for reducing soft to medium-hard materials and are frequently employed in the recycling industry.

Vertical Shaft Impact Crusher (VSI): VSI crushers use a different approach involving a high-speed rotor with wear-resistant tips. They are mainly used for shaping and producing high-quality sand and aggregate materials.

Hammer Crusher: Hammer crushers use hammers attached to rotating shafts to impact materials. They are commonly used for soft to medium-hard materials, such as coal, limestone, gypsum, and similar materials.

Roll Crusher: Roll crushers are compression-type crushers that use two rotating rolls to crush material between them. They are often used in mining and in smaller-scale applications, such as the preparation of coal.

Cage Mill Crusher: Cage mill crushers use multiple rows of hammers that spin quickly to crush the material. They are often used for very fine grinding and are used in various industries, including agricultural and food processing.

Cone Crushers for Crushing Ores: Cone crushers designed for crushing ores often have specific features and applications. For example, the HP (High Performance) and MP (Multi-Performance) series from Metso Outotec are commonly used for this purpose.

Specialized Crushers: There are various specialized crushers designed for specific tasks, such as bottle crushers, can crushers, and even ice crushers for the food and beverage industry.

The choice of crusher type depends on the material being processed, the desired end product, and other factors like the required production capacity and the abrasiveness of the material. Each type of crusher has its advantages and limitations, making it suitable for specific applications.

Types of Crushers

Crushers are used in various industries and applications to reduce the size of solid materials and make them more manageable for further processing or disposal. The primary purpose of crushers is to break down large or bulky materials into smaller, more easily handled particles. Here are some common uses of crushers in different industries:

Mining and Quarrying:

Jaw crushers, cone crushers, and gyratory crushers are used to crush and reduce large rocks and ores for further processing. They are used in primary, secondary, and tertiary crushing stages.

Construction and Demolition:

Crushers are used to recycle concrete and other construction materials. Impact crushers and jaw crushers are commonly used for this purpose.

Recycling and Waste Management:

Can crushers and bottle crushers are used to reduce the volume of recyclable materials like aluminum cans and glass bottles for easier recycling.

Food Processing:

Crushers are used in food processing to crush or grind ingredients such as grains, spices, and herbs. They are used in the production of flour, spices, and food powders.


Tablet crushers are used to reduce pharmaceutical tablets into a powder form, making it easier to mix with other ingredients and facilitate drug delivery.

Chemical Processing:

Crushers are used in chemical processing to reduce the size of chemicals and chemical compounds for various purposes, such as producing fine powders or ensuring proper mixing.

Forestry and Biomass:

Wood crushers, also known as wood chippers or shredders, are used in the forestry and biomass industries to reduce wood and wood waste into smaller particles for use in biomass energy production, mulch, or other applications.

Plastics and Recycling:

Crushers are used in the plastic and recycling industries to reduce the size of plastic materials for recycling or further processing.

Mineral Processing:

Crushers are essential in the mineral processing industry to reduce minerals like coal, iron ore, and limestone into smaller, more manageable sizes.

Cement Manufacturing:

Crushers are used to crush raw materials such as limestone, shale, and clay in the cement manufacturing process.

Oil and Gas Industry:

Crushers are used in the oil and gas industry to reduce drilling cuttings or to break down chunks of material in various processes.


Crushers are used to reduce the size of agricultural products, including grains, seeds, and feed materials, to prepare them for animal consumption.

Fertilizer Production:

Crushers are used to reduce large, lumpy materials into smaller granules or powders for the production of fertilizers.
