A crusher is an industrial machine used to break down large and hard materials such as stones, rocks, and ores into smaller, manageable pieces. Its main function is to make raw bulky materials suitable for further processing or transport. Crushing occurs through mechanical forces like compression, impact, or friction. Crushers come in various types, including jaw crushers, cone crushers, and impact crushers.

The working principle involves feeding material into the crusher chamber, where moving parts crush and break the material. The crushed material is then screened and separated according to size, producing different product fractions.

Crushers are widely used in mining, construction, road building, recycling, concrete and asphalt production. Proper crushing is essential for processing efficiency and product quality.

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

A mobile crusher is a transportable crushing unit mounted on wheels or tracks, designed for easy relocation. It provides fast setup and mobility on construction sites, mines, and temporary projects. It is usually powered by diesel engines or generators.

Material is loaded into the crusher hopper via loaders or conveyors. The crusher breaks the material, and vibrating screens separate it into different sizes.

Mobile crushers are preferred in projects with frequent site changes, low to medium capacity needs, and flexible operation such as construction, road repair, demolition, and small mining sites.

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

A fixed crusher is a stationary high-capacity crushing system, installed permanently at a designated site. It runs on electrical power and is often integrated with automation. Materials are continuously fed via feeders into the crushing units such as jaw, cone, or impact crushers. The crushed product is screened and sized.

Fixed crushers are mainly used in large mines, quarries, concrete and asphalt plants where high volume and continuous operation are required.

What are the Differences Between Fixed and Mobile Crushers?

Fixed crushers are permanent, electrically powered, high-capacity systems with automation, requiring infrastructure and immobile once installed. They offer higher efficiency and lower maintenance.

Mobile crushers are portable, usually diesel-powered, lower capacity, quick to install and move, with higher maintenance requirements but greater operational flexibility.

What is a Mobile Crushing and Screening Plant? What Does It Do? How Does It Work? Where Is It Used?

A mobile crushing and screening plant combines crushing and screening functions in a transportable unit, typically mounted on wheels or tracks, allowing site-to-site mobility.

Material is loaded into the crusher, broken down, and then passed through vibrating screens to separate different size fractions. This provides flexibility in production and easy adaptation to project needs.

These plants are used in quarries, construction sites, mining operations, recycling, and infrastructure projects. Their mobility, fast setup, and multifunctional capability provide cost and time advantages.
