A mobile rock impact crusher works by using a rotating rotor with blow bars to impact and break up materials, typically rocks or stones, into smaller pieces. Here's a step-by-step explanation of how it works:
Feeding: The raw material (e.g., rocks or stones) is fed into the crusher either by a hopper or an excavator, conveyor belt, or vibrating feeder.
Primary Crushing: The material enters the impact crusher and is struck by the blow bars attached to the fast-spinning rotor. These blow bars are made from durable materials and positioned to provide optimal impact force.
Impact and Breakage: As the rotor spins, the blow bars accelerate the rocks and hurl them against static breaker plates or curtains within the crusher housing. When the kinetic energy from the rotor and blow bars hits the rocks, it causes them to break into smaller pieces upon impact.
Secondary Crushing: The primary broken rocks may bounce back from the breaker plates and be struck by other blow bars for further crushing, depending on the crusher design and settings.
Sizing and Filtering: The crushed material is then moved to a discharge area. Depending on the crusher’s design, there might be screens or other systems to separate and classify the crushed material by size. Use of screens ensures uniformity in the size of the output product.
Conveying: The final, sized product is then conveyed away from the crusher for further processing or use.
Mobility: The mobile aspect means the crusher is mounted on tracks or wheels, allowing it to be moved easily to different locations or directly to the working site, which eliminates the need for transporting material to a fixed crushing plant.
This type of crusher is highly efficient in reducing rock and other materials to their desired sizes, and is used in various industries such as mining, construction, and recycling.
