Casing: The casing is the fundamental building block of primary impact crushers, providing robustness and durability to the crusher. It is typically constructed from high-quality materials such as steel or cast iron.

Hammers: Hammers, also known as pallets, are crucial components that deliver impacts to the materials during the crushing process. They are usually made from heavy-duty steel and mounted onto the rotor.

Liners: Liners are protective elements that line the inner surface of the crusher, safeguarding against wear and tear caused by material transport and processing. Liners are often made from highly durable alloys or ceramic materials.

Rotor: The rotor serves as the heart of the primary impact crusher, transmitting impacts to the materials. It is usually constructed from heavy-duty steel or cast iron.

Apron: The apron, also referred to as the apron plate, is a horizontal plate that allows discharged materials to fall and be transported. As materials exit the crusher, they fall onto the apron and are directed toward conveyors or other transportation systems.

These five essential components of primary impact crushers enable effective stone processing within facilities. The robustness of the casing, the impactful blows of the hammers, the protective function of liners, the energy transmission to materials by the rotor, and the orderly transport provided by the apron collectively support the efficient and safe operation of the crusher.
