1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Gérez-vous une opération de granulats à moyenne ou grande échelle et faites-vous face à des goulots d'étranglement constants dans votre circuit de concassage primaire ?? Les défis d'une usine de concassage de pierre de 250 300 tph sont importants: unpredictable feed size variations causing choke points, excessive wear part costs from suboptimal chamber designs, and unplanned downtime for liner changes that halt your entire production line. Each hour of stoppage represents thousands in lost revenue. En outre, atteindre une cohérence, inspec product gradation across multiple aggregate sizes often requires manual, inefficient adjustments. Are you questioning how to improve your plant’s overall availability beyond 90%, reduce your costperton for wear parts, and achieve a more predictable output to meet stringent project specifications? La solution ne réside pas seulement dans l’équipement, but in a fully integrated system designed from the ground up for this specific throughput class.

2. APERÇU DU PRODUIT

This 250300tph Stone Crushing Plant is a stationary, hardrock crushing and screening solution engineered for highvolume production of aggregates for construction, base de route, et ballast ferroviaire. It is designed as a complete circuit to accept large feed material (généralement jusqu'à 750 mm) and process it into precisely sized final products.

Flux de travail opérationnel:
1. Réduction primaire: Large dump trucks feed material into a robust primary jaw crusher for initial size reduction.
2. Secondaire & Concassage Tertiaire: Prescreened material is routed to secondary cone crushers for further reduction, with closedcircuit screening ensuring optimal recirculation.
3. Projection finale & Stockage: Crushed aggregate is conveyed to multideck vibrating screens for precise separation into final product sizes (par ex., 05mm, 510mm, 1020mm), qui sont ensuite acheminés vers des stocks désignés.

Champ d'application: Idéal pour le granit, basalte, cailloux de rivière, et autres matériaux abrasifs avec une résistance à la compression jusqu'à 350 MPa. Suitable for permanent quarry sites or longterm project bases.

Limites: Non conçu comme installation mobile ou semi-mobile; requires stable foundation and planned electrical infrastructure. Maximum feed size and final product range are determined by the specific crusher models selected within the plant configuration.
