A mobile crusher is a portable crushing and screening plant used for reducing the size of hard materials such as rock, ore, concrete, asphalt, and demolition debris. Mounted on tracked or wheeled chassis, it offers fast deployment and flexibility across different sites.

Working principle: Feed is introduced via a vibrating feeder into the primary crusher (jaw, impact, or cone). Crushed material is transported by conveyors to secondary and possibly tertiary crushers. Finally, a screening unit classifies the material into size fractions. Oversized pieces are recirculated for further processing.

Applications include:

  • Infrastructure projects (roads, dams, bridges)

  • On-site recycling of construction and demolition waste

  • Quarrying and mining operations

  • Temporary or remote projects requiring mobile production

What Is a Stationary Crusher, What Is It Used For, How Does It Work, and Where Is It Used
A stationary crusher is a fixed, integrated crushing and screening facility designed for long-term, high-capacity material processing. Commonly installed in quarries, mining sites, and asphalt/concrete plants.

Material is delivered by trucks into feed bunkers and processed through primary, secondary, and possibly tertiary crushers. The output is screened by size and conveyed to storage areas. The system is typically automated and powered by electricity.

Applications include:

  • Continuous operations in quarries and mines

  • Supply of aggregates for concrete and asphalt plants

  • Industrial-scale material processing

  • Large infrastructure projects

Differences Between Stationary and Mobile Crushers
Mobile crushers are portable and offer quick setup and site flexibility; stationary crushers are fixed, offering higher capacity and lower long‑term operating costs. Mobile systems suit short‑term or multiple sites; stationary systems are intended for continuous production.

What Is an 18‑Manganese Secondary Impact Crusher, What Is It Used For, How Does It Work, and Where Is It Used
An 18-manganese secondary impact crusher refers to secondary crushing equipment whose impact crusher hammers or liners (pallets) are made from high-manganese steel alloy containing approximately 18% manganese. This alloy offers excellent wear resistance and impact toughness.

How it works: High‑speed rotating rotor fitted with manganese steel pallets propels material against breaker plates. After primary crushing, material enters the secondary crusher where pallets apply high-energy impacts. The result is finer, more uniform particles. The manganese alloy ensures extended service life under severe abrasion.

Applications include:

  • Manufacture of fine, cubical aggregates for concrete and asphalt

  • Secondary crushing in quarries and mining operations

  • Crushing recycled construction materials

  • High‑performance aggregate production in harsh environments
