Product Details

This apparatus is designed to reduce the size of hard, solid materials like rocks and minerals through compressive force, simulating the primary crushing stage used in mining and aggregate processing. It is used to demonstrate the fundamental principles of size reduction by applying mechanical pressure between a fixed and a reciprocating jaw. The crusher features a robust cast steel and mild steel construction with a motor that transmits power via a belt to an eccentric shaft, driving the moving jaw in a periodic motion. As the jaw moves towards the fixed jaw, the angle of the toggle plate increases, creating a compressive action that crushes the feed material. When the jaw retracts, the crushed product discharges from the bottom outlet. The unit accepts feed sizes up to 2 inches and reduces them to a maximum of 8mm at an operating speed of approximately 330 RPM. Its primary applications are in mineral processing, mining, and construction materials education. The key benefit is the hands-on demonstration of compressive crushing mechanics, enabling students to understand factors affecting crusher performance, such as feed size and machine settings, and to observe the practical operation of a fundamental piece of comminution equipment.
