1. ОТКРЫТИЕ С УПРАВЛЕНИЕМ PAINPOINT

Are you managing a highvolume aggregate operation and facing persistent bottlenecks that erode profitability? Для руководителей заводов и инженерных подрядчиков, а 250300 т/ч камнедробильная установка — важнейший производственный актив, yet common operational challenges can significantly undermine its return on investment. These include unpredictable downtime from component failures under continuous heavy load, inconsistent final product gradation leading to premium product loss, and escalating maintenance costs from abrasive wear. Более того, inefficient power utilization and inflexible configurations that cannot adapt to varying feed materials or product specifications create recurring inefficiencies. How do you ensure your crushing circuit delivers its rated 300 tonperhour capacity consistently, maintains precise product specs with minimal waste, and operates with predictable maintenance costs? The specification of the plant itself is the foundational answer.

2. ОБЗОР ПРОДУКТА

This specification outlines a complete, стационарный CE Marked 250300tph Stone Crushing Plant, designed for highvolume production of aggregates for construction, дорожная база, и железнодорожный балласт. The plant is engineered as a threestage crushing and screening circuit for processing mediumhard to hard stone such as granite, базальт, или известняк.

The operational workflow follows a logical, efficient path:
1. Первичное дробление: Большой загружаемый материал (≤750 мм) сокращается за счет надежной щековой дробилки первичного дробления..
2. вторичный & Третичное дробление: The output is conveyed to a cone crusher for further size reduction, ensuring optimal particle shape.
3. Скрининг & Накопление запасов: Material is classified via multideck vibrating screens; негабаритный размер рециркулируется, while correctly sized fractions are conveyed to designated stockpiles.

Application scope includes largescale quarry operations, major infrastructure project support sites, и специализированные площадки для поставки заполнителей. A key limitation is that this plant configuration is designed as a stationary installation; for frequent relocation, a modular or mobile variant would be more appropriate.
