A crusher is an industrial machine used to reduce large rocks, stones, or mineral blocks into smaller, more manageable pieces. Crushers are essential equipment in industries such as mining, construction, road building, concrete production, and aggregate manufacturing.

The operation relies on applying mechanical force such as compression, impact, or shearing to break the material. Feed materials are delivered into the crusher chamber, where crushing units reduce their size. The crushed product is then screened and sorted into various sizes for use.

Applications include quarries, mining operations, infrastructure projects, recycling facilities, dam constructions, ports, and airport fill works.


2. What is a mobile crusher, what is it used for, how does it work, and where is it used?

A mobile crusher is a portable stone crushing machine mounted on tracks or wheels. It allows on-site crushing and screening of materials without needing transportation to a stationary plant.

These units eliminate the time and cost of fixed installations. All systems, such as feeders, crushers, screens, and conveyors, are integrated on a single mobile chassis. Material is crushed on-site, reducing transportation cost and saving time.

It is widely used in road construction, mining sites, demolition waste recycling, dam building, and asphalt production.


3. What is a stationary crusher, what is it used for, how does it work, and where is it used?

A stationary crusher is a permanent crushing and screening plant installed in one fixed location. It is suitable for high-capacity, long-term aggregate production or large mining operations.

The material passes through multiple crushers in sequence—primary, secondary, and tertiary—until it reaches the desired size. These plants offer greater efficiency and productivity for large-volume production.

Applications include cement plants, large-scale quarries, mineral processing facilities, and infrastructure megaprojects.


4. What are the differences between a stationary and a mobile crusher?

  • Mobility: Mobile crushers can move easily; stationary ones are fixed.

  • Installation Time: Mobile crushers require minimal setup; stationary plants need longer installation.

  • Cost: Stationary units have higher initial costs but lower long-term operational costs.

  • Capacity: Stationary crushers typically offer higher throughput.

  • Use Case: Mobile crushers suit temporary and medium-scale projects; stationary units serve large, ongoing operations.

  • Maintenance: Mobile units require more frequent maintenance; stationary systems are more stable.


5. What is a horizontal shaft mobile crusher, what is it used for, how does it work, and where is it used?

A horizontal shaft mobile crusher uses an impact mechanism with a horizontally mounted rotor to break materials. Horizontal Shaft Impact (HSI) crushers are effective for medium-hard rocks and recyclable materials.

Material is fed into the chamber and strikes impact plates at high speed, breaking into smaller fragments. Being mobile, it can be deployed directly at construction or demolition sites.

It is widely used for limestone and basalt processing, urban demolition, asphalt recycling, and road base production.
