A crusher is a heavy-duty industrial machine designed to reduce large volumes of hard materials such as rocks, ores, and demolition waste into smaller, uniform, and usable pieces. These machines are essential in industries such as road construction, concrete production, dam projects, mining, and recycling. The process begins when material is loaded through a feeder belt or hopper into the crushing chamber, where it is broken by mechanical force—either compression or impact. The resulting aggregates are then passed through screening systems to separate them by size and transported to storage areas via conveyor belts. Crushers deliver the fundamental aggregates used across many industrial applications.

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

A mobile crusher is a portable crushing and screening plant mounted on wheels or tracks that allows direct on-site processing—without the need for a fixed facility. This enables immediate material handling and classification, eliminating transport costs and delays. The process begins with loading material into the machine via an excavator or loader. Primary crushing takes place using a jaw or impact crusher, followed by size separation through screens. The crushed output is then conveyed and stockpiled directly at the site. Mobile crushers are widely used in projects like road construction, dam building, railways, demolition recycling, and operations in remote and mountainous areas where flexibility and mobility are key.

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

A stationary crusher is a permanently installed, high-capacity crushing facility designed for long-term and heavy-duty operation. Common settings include large quarries, mining operations, and industrial processing plants. Raw material is delivered by truck to a feeder, then undergoes primary crushing followed by secondary and possibly tertiary crushing stages. The material is sized using screening units and then conveyed to storage bins or stockpiles. Designed for continuous and high-tonnage output, these systems are used in aggregate production, cement factories, large infrastructure developments, and bulk ore pre-processing in mining.

4. What are the differences between stationary and mobile crushers?

The primary distinction lies in mobility and setup. Mobile crushers can be moved and redeployed across different job sites; they feature quick setup and lower capital cost but higher operational expenses due to fuel and maintenance. Stationary crushers are fixed installations requiring extensive groundwork, infrastructure, and power connection; they serve long-term, large-scale operations and offer lower unit costs with higher capacity. Mobile crushers are ideal for short-term and flexible tasks, whereas stationary plants suit permanent, high-production environments.

5. What is an ore crushing and screening plant, what is it used for, how does it work, and in which fields is it used?

An ore crushing and screening plant is a processing facility that prepares mined ore by crushing and classifying it into sizes suitable for subsequent beneficiation and refining processes. Its purpose is to reduce ore to dimensions where valuable minerals can be efficiently separated. Trucks deliver ore to a hopper, and it goes through primary crushing. Subsequent stages include secondary and tertiary crushing for finer fragmentation. The material is then screened for precise size separation and stored on-site. Such plants are common in copper, iron, gold, chromium mining operations and also in facilities processing industrial minerals and rare earth elements.
