Jaw Crushers
Powerful and Reliable Size Reduction Solutions for Primary Crushing
Jaw crushers are powerful and reliable systems used in the primary crushing stage of coarse and hard materials. They provide controlled feed size reduction and prepare the material for downstream process stages. With high feed capacity, robust construction, and wide feed opening design, they ensure uninterrupted operation even under demanding conditions.
Operating Principle
Jaw crushers operate on the principle of compressing material between a fixed and a moving jaw plate. The moving jaw is driven back and forth by an eccentric shaft, and the material is crushed in the narrowing gap between the two jaws, reducing it to the desired size.
The crushing ratio is controlled by the jaw opening and the discharge setting. Material hardness, moisture content, and feed size are determining parameters for jaw profile and motor power selection.
Process Advantages
Secondary Impact Crushers
Efficient Secondary Crushing Solutions for Cubical Product and Controlled Size Reduction
Secondary impact crushers are efficient crushing systems used after primary crushing to achieve more controlled size reduction and a more uniform, cubical product. Their strong rotor design, durable wear parts, and easy maintenance access combine high performance with operational convenience.
Operating Principle
Secondary impact crushers break material through impact plates mounted on a high-speed rotating rotor. After hitting the rotor, material is directed toward blow bars and the inner surfaces of the crushing chamber, undergoing staged size reduction.
By adjusting the blow bars and rotor speed, the desired output size and product shape can be achieved. This structure provides a distinct advantage in applications requiring cubical and homogeneous product distribution.
Process Advantages
Rotor Impact Mills
High-Performance Solutions for Quality Crushed Sand Production and Fine Crushing
Rotor impact mills operate with a high-performance vertical-shaft crushing principle and are used to achieve high reduction ratios, good particle shape, and consistent particle size distribution. They provide an effective solution especially for processing low to moderately abrasive mineral materials and for producing high-quality crushed sand.
Operating Principle
Rotor impact mills operate on the principle of throwing material into the crushing chamber via a high-speed rotor rotating on a vertical axis and breaking it by impact against crushing surfaces. This design provides controlled crushing and shaping through high kinetic energy.
Product size and particle shape can be optimized by adjusting rotor speed and crushing chamber geometry. Closed-circuit operation enables more precise control over the desired gradation.
Process Advantages
Hammer Crushers
Effective Crushing Solutions for Fine Product from Soft and Medium-Hard Materials
Hammer crushers are effective solutions for the secondary or tertiary crushing of soft or medium-hard, low-abrasive materials. They are especially suitable for applications requiring finer product and controlled grading. Thanks to the lower grate design, the desired product size can be approached more effectively, and in some applications the need for a separate screening stage can be reduced.
Operating Principle
Hammer crushers operate on the principle of breaking material through impact by hammer elements mounted on a high-speed rotating rotor. Crushed material passes through the lower grate to reach the desired size.
By changing the grate aperture size and hammer configuration, different product sizes can be obtained. This design eliminates the need for a separate screening step in some applications.
