A mobile crusher is a portable crushing and screening machine capable of processing hard materials such as rocks, stones, and construction waste directly at job sites. It is more flexible and easily transportable compared to stationary plants. Mobile crushers break down large volumes of material into smaller, reusable sizes, reducing the need for raw materials and transport costs. Material is fed into the machine through a vibrating feeder, crushed in the crusher unit, and then sorted by size using a screening system. Conveyors carry the output to storage. They typically operate on diesel or electric power. They are widely used in construction waste recycling, road building, mining, and infrastructure projects, and are also favored for emergency interventions due to their mobility.

A crusher is a machine used to break down large rocks and stones into smaller pieces. It can be either stationary or mobile. Its main purpose is to produce construction-grade material in usable sizes. Crushers operate using jaw, impact, or cone crushing systems. Material is fed into the machine, crushed, screened for appropriate size, and oversized material is returned to the crusher. Crushers are essential in road construction, concrete production, railway infrastructure, dam building, and also in aggregate production and recycling of construction debris.

A closed-circuit crushing and screening plant is a system in which crushed material is screened and recirculated to the crusher until it reaches the desired size. This ensures the output is uniform, high-quality, and consistent. The process begins with feeding material into the system, where it is crushed, screened, and oversized fragments are returned for reprocessing. Automated control systems manage this process efficiently. These facilities are used in aggregate production, high-grade concrete and asphalt manufacturing, and large-scale infrastructure projects. They can be mobile or stationary depending on the project needs.
