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 капитальным активом, однако его производительность напрямую влияет на вашу прибыль. Common operational challenges include:
Непостоянная пропускная способность: Fluctuations in feed material hardness or size leading to an average output below the 280tph design target, causing project delays and missed delivery schedules.
Чрезмерное время простоя: Frequent mechanical failures in key components or lengthy changeover times for maintenance, resulting in hundreds of lost production hours annually.
Высокие эксплуатационные расходы: Uncontrolled wear part consumption, inefficient power draw per ton of processed material, and the labor intensity of routine monitoring.
Вариативность качества продукции: Inability to consistently meet multiple spec products (например, 05мм, 1020мм, 2040мм) simultaneously due to inflexible or poorly calibrated crushing stages.
Ограничения масштабируемости: A fixed plant configuration that cannot adapt to changing project demands or feed materials without significant capital reinvestment.

Центральный вопрос: how do you select a 250300tph crushing plant that transforms these cost centers into reliable, predictable production?

2. ОБЗОР ПРОДУКТА

Этот продукт представляет собой полный, стационарный 250300 TPH Hard Stone Crushing and Screening Plant. It is engineered for continuous, highvolume production of aggregates for large infrastructure projects, commercial concrete batching, and road base construction.

Операционный рабочий процесс:
1. Первичное дробление: Большой загружаемый материал (≤750 мм) is reduced to ≤200mm by a robust primary jaw crusher.
2. вторичный & Третичное дробление: Material is conveyed to a cone crusher circuit for further reduction, producing precisely shaped intermediates.
3. Скрининг & Классификация: Multipledeck vibrating screens separate crushed material into specified finished product sizes.
4. Рециркуляция: Oversize material is automatically returned via conveyors to the appropriate crusher for reprocessing (замкнутая конструкция).
5. Накопление запасов: Finished aggregates are conveyed to designated stockpiles for loadout.

Область применения & Ограничения:
Объем: Ideal for processing granite, базальт, речная галька, and other abrasive materials with compressive strength up to 350MPa. Suited for permanent quarry sites or longduration (3+ год) project bases.
Ограничения: Not designed as mobile or semimobile equipment; relocation requires disassembly. Maximum feed size and final capacity are contingent on specific material characteristics. Not optimal for processing sticky or highclay content materials without prescreening/scalping modifications.
