Jaw crusher: single toggle or double toggle?

Schéma de principe d'un concasseur à mâchoires WEIL : mâchoire fixe, mâchoire mobile et chambre de concassage

The jaw crusher is the oldest and most widespread machine in primary crushing. Its principle is simple — compressing material between a fixed jaw and a swing jaw — but it comes in two technologies whose behaviour differs sharply: single toggle and double toggle. Understanding what separates them is understanding why one now dominates the […]

Vertical shaft impact crusher (VSI): working principle

Schéma de principe d'un concasseur à axe vertical VSI WEIL : rotor, aubes de projection et chambre de concassage

The vertical shaft impact crusher — commonly called a VSI, for vertical shaft impact — holds a place of its own in a crushing plant. Where gyratory and jaw crushers compress material between two surfaces, the VSI throws it. This difference in principle explains both its remarkable cubicity and its particular wear behaviour. Throwing rather […]

Gyratory crusher: working principle

Schéma de principe d'un concasseur giratoire WEIL : noix mobile, bol fixe et excentrique

The gyratory crusher is today the most widespread machine in the preparation stages for ores and minerals. Continuous throughput, high reduction ratios, the ability to handle almost every crushing problem: these machines have benefited from decades of continuous research and rank among the best performers on the market. Understanding their working principle makes it possible […]
