1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Are unpredictable crusher breakdowns causing thousands in lost production and emergency repair costs? Is inconsistent product gradation from your primary crushing stage creating bottlenecks and quality control issues downstream? Are you facing escalating costs for wear part replacement and excessive energy consumption per ton of processed material? These operational challenges directly impact your bottom line through unplanned downtime, wasted power, and compromised final product value.

The selection of your primary reduction equipment is a critical capital decision. How do you ensure maximum uptime, coûts d'exploitation prévisibles, and optimal feed size reduction for your specific mineralogy and production goals? The solution requires a machine engineered not just to crush, but to perform reliably as the cornerstone of your entire processing circuit.

2. APERÇU DU PRODUIT

This content details our bespoke contract manufacturing service for Concasseurs à mâchoires primaires. We engineer and build heavyduty jaw crushers designed as the first stage in fixed or semimobile hard rock crushing plants. The operational workflow is purposebuilt for primary reduction: (1) Matière première de grande taille (ROM) est livré via un camion à benne basculante ou un chargeur dans le chargeur vibrant pour grizzly. (2) Oversize material is directed into the crusher’s robust chamber, where a reciprocating jaw exerts immense compressive force against a stationary jaw. (3) The crushed material discharges through an adjustable gap at the bottom, determining the product size. (4) Crushed output is conveyed to the next stage of processing.

Application scope includes primary crushing of abrasive materials like granite, basalte, minerai de fer, et béton recyclé. Key limitations involve material hardness exceeding designed specifications (généralement jusqu'à 350 Résistance à la compression MPa) and the presence of excessive, uncrushable contaminants like metal.
