1. ОТКРЫТИЕ С УПРАВЛЕНИЕМ PAINPOINT

Вы управляете средним и крупным предприятием по производству агрегатов и сталкиваетесь с постоянными узкими местами, которые снижают прибыльность?? Для руководителей заводов и инженерных подрядчиков, камнедробильная установка производительностью 250–300 тонн в час является важнейшим активом, однако общие операционные проблемы напрямую влияют на вашу прибыль. Consider these frequent issues:
Непостоянная пропускная способность & Время простоя: Unplanned stoppages due to feeder blockages, crusher overloads, or conveyor misalignment can cost thousands per hour in lost production and idle labor.
Высокая эксплуатационная & Затраты на техническое обслуживание: Частая замена изнашиваемых деталей, high energy consumption per ton of output, and the need for specialized maintenance crews steadily increase your cost per aggregate ton.
Плохая форма продукта & Контроль градации: Inconsistent output leads to excess fines or outofspec material, reducing the market value of your end product and causing rejections.
Rigid Plant Layout & Ограничения масштабируемости: Fixed designs struggle to adapt to changing feed material hardness or required product mixes, forcing costly retrofits or operating below optimal capacity.

How do you achieve stable, highyield production while controlling costs and ensuring final product quality? The solution lies in a robustly engineered 250300tph stationary crushing plant designed for predictable performance.

2. ОБЗОР ПРОДУКТА

This solution is a complete stationary stone crushing and screening plant engineered for a nominal output of 250 к 300 метрические тонны в час (т/ч) готового заполнителя. It is designed as a primarytotertiary processing system for mediumhard to hard stones like granite, базальт, и известняк.

Операционный рабочий процесс:
1. Первичное дробление: Большой загружаемый материал (≤750 мм) is reduced by a heavyduty jaw crusher or gyratory crusher.
2. вторичный & Третичное дробление: The primary crushed material is further processed by cone crushers for size reduction and improved particle shape.
3. Скрининг & Классификация: Vibrating screens separate material into precise size fractions, routing oversize back to crushers and directing onspec product to final stockpiles.

Область применения: Ideal for large quarry operations, major infrastructure project support (шоссе, железные дороги), and commercial aggregate supply yards requiring highvolume, последовательный вывод.

Ключевые ограничения: Feed material hardness must be within specified limits (например, до 300 МПа прочность на сжатие). Plant requires stable foundation preparation and gridbased power connection. Not designed for mobile or frequent relocation.
