Impact Crusher

Limestone, the main raw material for cement production, needs to be crushed in multiple stages. Impact crushers are often used in the second or third stage of crushing. It can process limestone with a feed size of ≤700mm. The high-speed rotation of the rotor drives the hammer to impact the material, crushing the raw material into fine particles below 30mm, meeting the feeding requirements of the raw mill. The product is equipped with high-chromium hammers, wear-resistant impact linings, and unique toothed impact linings, which are especially suitable for hard rock crushing. The equipment is highly efficient and energy-saving. The product is in the shape of a cube, and the discharge size is adjustable, which simplifies the crushing process.

Industry knowledge

The impact crusher is a key piece of equipment for limestone crushing in cement production lines, primarily used for secondary or tertiary crushing. Using high-speed impact crushing, this equipment crushes limestone ≤700mm to less than 30mm, meeting the particle size requirements of raw mills. It is energy-efficient, highly efficient, and provides excellent particle shape, making it a vital piece of equipment for modern cement production lines. Jiangsu Haijian Co., Ltd. is a professional impact crusher manufacturer and company. We provide specialized cement production equipment, industrial solid waste incineration equipment, and specialized equipment for mining and metallurgy applications.

The impact crusher further crushes limestone (≤700mm) after primary crushing to ≤30mm, providing qualified raw material for raw mills with a particle size qualification rate exceeding 95%. Its unique impact crushing method produces cubic particles with a flake content of less than 10%, surpassing that of jaw crushers (typically 20-30%). The adjustable impact plate design allows for dynamic adjustment of the discharge particle size (ranging from 10-50mm), eliminating screening steps and reducing system complexity.

In terms of ongoing maintenance, the impact crusher emphasizes ease of maintenance and a long lifespan. Wear parts are symmetrically mounted, allowing for adjustable use when the hammer wear reaches 30mm on one side, effectively extending the replacement cycle. The bearing system is equipped with temperature monitoring and automatic lubrication to ensure reliable operation of key components. An intelligent monitoring system collects operating parameters such as vibration and current in real time, providing early warning of potential failures. Routine maintenance focuses on regularly checking hammer wear, maintaining proper working clearances, and promptly replacing symmetrically positioned wear parts. These measures ensure an annual equipment operation rate exceeding 98%, significantly reducing production and maintenance costs.
