A mobile crusher is a portable crushing and screening plant designed to reduce the size of hard materials such as stone, rock, concrete, asphalt, or ore directly at the work site. Mounted on wheels or tracked chassis, it can be quickly deployed and easily relocated between different locations.

Typical components include a feed hopper, primary crusher (jaw), secondary or tertiary crushers (impact or cone), a screening unit, and conveyor belts. The material is initially loaded into the hopper. It is then conveyed to the crusher where it is broken down by force. The crushed material passes through a screening system to sort it by size and is transported via conveyors to storage areas. Most mobile crushers use diesel engines or onboard generators, enabling use in locations where site power infrastructure is unavailable.

Mobile crushers are commonly used in road construction, demolition recycling, quarrying, mining operations, and temporary or shifting project environments. Their portability, rapid setup, and onsite efficiency make them advantageous for flexible, decentralized operations.

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 crushing and screening plant designed for long-term, high-capacity material processing. Typically installed on a concrete foundation, it serves as a permanent production facility.

Materials are delivered to the site via truck or conveyor, fed into the crusher system via feeding units, and processed through primary, secondary, and tertiary crushers. Following crushing, the material is classified by vibrating screens, and final products are conveyed to storage or subsequent processing lines. Stationary crushers are usually powered by grid electricity and controlled via automation systems.

These systems are ideal for high-volume production facilities such as large quarries, concrete and asphalt plants, mining operations, and major infrastructure projects, offering efficiency, automation, and long-term reliability.

Differences Between Stationary and Mobile Crushers

  • Mobility: Mobile crushers can be easily moved; stationary crushers are fixed in one location.

  • Installation Time: Mobile systems are set up quickly and operational shortly after arrival; stationary systems require substantial preparation and construction time.

  • Capacity: Stationary systems handle much higher throughput; mobile units are suitable for mid-range project volumes.

  • Power Supply: Mobile units often run on diesel generators; stationary systems require grid power.

  • Investment Cost: Mobile systems have minimal site preparation costs; stationary plants require significant infrastructure investment.

  • Use Case: Mobile crushers serve temporary or site-varying projects; stationary crushers are best for long-term high-throughput operations.

What Are Crusher Blow Bars (Pallets), What Are They Used For, How Do They Work, and Where Are They Used

Crusher blow bars (also known as rotor blow bars or pallets) are heavy-duty, wear-resistant steel castings that are installed on the rotor in impact or tertiary crushing systems. Typically made from high-manganese steel alloy (16‑18% or 19‑21% manganese), they are designed to resist abrasion and impact.

The working principle: material enters the crusher chamber, where fast-moving rotor pallets strike it. The kinetic energy of the blow bars causes the material to fracture. While facilitating crushing, blow bars also protect the underlying rotor assembly from wear. They are replaceable components; worn bars are swapped out to maintain crushing efficiency.

These components are widely used in industries requiring intense crushing processes such as aggregate quarries, mining crushing plants, recycling facilities processing concrete or asphalt rubble, and asphalt/concrete production plants.
