A crusher is a heavy industrial machine used primarily to reduce large pieces of rock, ore, or stone into smaller, more manageable sizes. Its main function is to prepare raw materials for further processing by breaking them down mechanically. Crushers are essential in mining, construction, quarrying, and recycling industries.

The working principle involves applying mechanical forces to the material, such as compression, impact, or shear, to fracture and reduce it. Common types include jaw crushers, cone crushers, and impact crushers. Jaw crushers work by pressing material between a fixed and a moving jaw. Cone crushers crush by squeezing material between a rotating cone and a stationary shell. Impact crushers break material by striking it with high-speed rotating hammers or rotors.

Crushers are widely used in producing aggregates for roads and buildings, mining operations, concrete production, and waste recycling.

What is a Mobile Crusher? What Does It Do? How Does It Work? Where Is It Used?

A mobile crusher is a portable crushing plant mounted on wheels or tracks, allowing it to be moved easily between sites. It offers flexibility for short-term projects, rapid deployment, and easy relocation.

Mobile crushers generally combine a feeding system, crushing unit, and screening system on one mobile platform. Material is fed, crushed, and screened on-site, allowing for processing of rocks, minerals, or demolition waste directly at the job location.

They are widely used in temporary construction sites, small to medium mining operations, roadworks, and recycling projects that require mobility and quick setup.

What is a Stationary Crusher? What Does It Do? How Does It Work? Where Is It Used?

Stationary crushers are large, fixed plants designed for continuous and high-capacity crushing tasks. They are built for durability, high throughput, and long-term operation.

Material is fed into the crushing unit via conveyors or feeders, mechanically reduced in size, and sorted using screening equipment. These crushers are mainly used in large-scale mining operations, quarries, and industrial facilities requiring steady, high-volume material processing.

Differences Between Stationary and Mobile Crushers

The fundamental differences lie in portability, capacity, and flexibility. Stationary crushers are heavy-duty, fixed installations optimized for long-term, high-volume crushing. Mobile crushers prioritize portability and fast setup but generally have lower capacity.

Choosing between stationary and mobile crushers depends on project size, duration, and site mobility requirements.
