A mobile crusher is a portable crushing and screening system used to process hard and bulky materials such as stone, ores, asphalt, concrete, and demolition waste. Its mobility allows it to be transferred easily between job sites, reducing setup time and operational costs in infrastructure and construction projects.

The working principle involves feeding raw material into a hopper that delivers it to the primary crusher. After the initial breakage, the material is transferred via conveyor belts to secondary or tertiary crushers. It is then screened into various sizes. Oversized materials may be recirculated back for additional crushing.

Mobile crushers are widely used in construction projects, road building, dam construction, mining, and recycling 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 permanent facility designed to handle large-scale, continuous crushing operations. It is installed at a fixed location and suited for long-term projects requiring high production volumes.

Raw material is dumped into the feeding bunker by trucks, then processed through primary and other crushers to reduce size. After classification via screening units, material is conveyed to stockpiles. The system is usually controlled automatically, ensuring efficient, uninterrupted production.

Stationary crushers are used extensively in quarries, mining operations, concrete and asphalt production facilities.

Differences Between Stationary and Mobile Crushers

  • Setup and Portability: Mobile crushers offer fast setup and are easily transportable. Stationary crushers are fixed and not relocatable.

  • Capacity: Stationary crushers typically have higher production capacities.

  • Cost: Stationary plants offer lower long-term operational costs. Mobile units suit short-term projects but have higher ongoing costs.

  • Application: Mobile units are ideal for flexible use across various job sites. Stationary systems serve large, continuous production environments.

What Is the 3rd Impact Pallet in a Primary Impact Crusher, What Is It Used For, How Does It Work, and Where Is It Used

The third impact pallet in a primary impact crusher is the final surface where material is struck after passing through the rotor and the first two impact pallets. Its function is to perform a final reduction of material already close to the target size, enhancing uniformity and achieving fine granularity.

This pallet directly affects product quality and allows fine-tuning through adjustable spacing. It's made of wear-resistant, high-grade alloy steel to handle repeated impacts.

It is used in high-precision applications such as concrete production, asphalt base manufacturing, road construction, and aggregate production.
