1. ОТКРЫТИЕ С УПРАВЛЕНИЕМ PAINPOINT

Вы управляете средним и крупным предприятием по производству агрегатов и сталкиваетесь с постоянными узкими местами, которые снижают прибыльность?? The challenges of a 250300 tph stone crushing plant are often clear: inconsistent feed material causing crusher stalls and wear, excessive downtime for liner changes and maintenance, high energy consumption per ton of output, and difficulty meeting strict aggregate specifications consistently. These issues translate directly to lost revenue. How much production are you losing during changeovers? What is the true cost of unplanned downtime on your project timelines? Are your operational costs under control, or are they being inflated by inefficient processes and premature component failure? A wellengineered, customized OEM 250300tph stone crushing plant is designed to systematically address these exact pain points.

2. ОБЗОР ПРОДУКТА

This solution is a complete, heavyduty stationary or semistationary stone crushing plant engineered for reliable production of 250 к 300 metric tons per hour of crushed aggregate. It is not an offtheshelf product but a configured system built around core OEM crushers, экраны, and conveyors.

Операционный рабочий процесс:
1. Первичное сокращение: Большой загружаемый материал (до 750 мм) is reduced by a robust primary jaw or gyratory crusher.
2. Вторичное/Третичное дробление: Material is conveyed to secondary cone or impact crushers for further size reduction and shaping.
3. Размеры & Классификация: Crushed material passes through multideck vibrating screens to separate it into precise product fractions (например, 05мм, 510мм, 1020мм).
4. Накопление запасов & Рециркуляция: Onspec material is conveyed to stockpiles. Oversize material is automatically recirculated back into the circuit for recrushing.

Область применения: Ideal for large quarry operations, major infrastructure projects (шоссе, железные дороги), и коммерческие заводы по производству бетона/асфальта, требующие больших объемов, consistent aggregate supply.
Ограничения: Requires significant capital investment and planned site preparation. Optimal performance depends on correct system configuration for the specific feed material characteristics (абразивность, silica content, влага).
