A hammer crusher is an impact crushing machine primarily used for the intermediate and fine crushing of medium-hard and brittle materials. After entering the crushing chamber, the feed is progressively reduced by the impact of high-speed rotating hammers and by collisions with the liners and other particles. Material that reaches the required size passes through the grate openings, while oversized particles remain in the crushing chamber for further reduction.
The machine supports both dry and wet crushing. Dry operation is suitable for materials such as limestone, coal, gypsum, coke and shale. Wet operation is particularly suitable for lateritic gold ores . Water can be added during crushing to produce a slurry that feeds directly into the downstream mineral processing circuit.
A hammer crusher is typically selected when processing brittle, medium-hard, or low-abrasive materials, such as limestone, coal, gypsum, or shale. It is suitable for applications that require a large reduction ratio, allowing relatively large feed materials to be crushed to smaller sizes in a single stage. In many cases, this can reduce the need for secondary or tertiary crushers, helping to simplify the crushing process and lower overall equipment investment.
