1. PYNPUNT GEDREWE OPENING

Are you managing a highvolume aggregate operation and facing persistent bottlenecks that erode profitability? Vir aanlegbestuurders en ingenieurskontrakteurs, a 250300tph stone crushing plant is a critical production asset, yet common operational challenges can significantly undermine its return on investment. Consider these frequent issues:

Ongeskeduleerde stilstand: Component failures in key crushers or screens halt your entire line, costing thousands per hour in lost production and idle labor.
Inconsistent Final Product Quality: Fluctuations in grain size and shape result from poorly synchronized or overloaded crushing stages, leading to product rejection and reduced market value.
Hoog operasioneel & Onderhoudskoste: Excessive wear part consumption, high energy consumption per ton processed, and laborintensive routine maintenance steadily increase your cost of ownership.
Onbuigsame konfigurasie: Can your plant efficiently adapt to changing feed material hardness or produce different product gradations for various contracts without major reconfiguration?

Die sentrale vraag is: hoe kan jy betroubare bereik, hightonnage output with predictable operating costs and superior product control? The solution lies in a professionally engineered 250300tph stone crushing plant designed for industrial durability and operational efficiency.

2. PRODUK OORSIG

This solution is a stationary 250300 tonperhour (tph) harde rots vergruis- en siftingsaanleg. Dit is ontwerp vir primêre kontrakteurs en totale vervaardigers wat konsekwent vereis, highvolume output of specification aggregates from materials like granite, basalt, and limestone.

Operasionele werkvloei:
1. Primêre verplettering: Groot voermateriaal (≤750 mm) is reduced to ≤200mm by a robust primary jaw crusher.
2. Sekondêr & Tersiêre verplettering: Material is conveyed to secondary cone crushers for further reduction, with optional tertiary cone or impact crushers for precise shaping and final size reduction.
3. Sifting & Klassifikasie: Multipledeck vibrating screens accurately separate crushed material into required finished product sizes (bv., 05mm, 510mm, 1020mm).
4. Materiaalhantering & Voorraad opgaar: Closedcircuit conveyors recirculate oversize material while radial stackers build controlled stockpiles of finished products.

Toepassingsomvang & Beperkings:
Omvang: Ideal for largescale quarry operations, major infrastructure projects (snelweg, rail), and commercial aggregate supply yards requiring sustained high output.
Beperkings: Nie ontwerp vir draagbare of mobiele toepassings nie. Feed material compressive strength should typically not exceed 350 MPa without specific configuration adjustments. Requires stable foundation and gridbased power supply.
