1. ОТКРЫТИЕ С УПРАВЛЕНИЕМ PAINPOINT

Управление карьером известняка или заводом по переработке известняка представляет собой, дорогостоящие проблемы. Вы постоянно сталкиваетесь с узкими местами, которые ограничивают истинную производительность вашего предприятия?? Key pain points include:

Чрезмерное время простоя первичной дробилки: Bridging and clogging at the primary crusher feed hopper halts the entire production line, потери производительности и простоя труда обходятся тысячами в час.
Высокие затраты на замену изнашиваемых деталей: The abrasive nature of raw limestone rapidly degrades standard equipment liners, buckets, and teeth, что приводит к частым, expensive maintenance cycles and parts inventory burdens.
Неэффективная обработка материалов & Предварительный скрининг: Fines and subfeedsize material unnecessarily entering the primary crusher reduces its effective capacity for size reduction and accelerates wear.
Inconsistent Feed to Downstream Processing: Fluctuating feed size and volume from the quarry face to the processing plant creates instability, reducing the efficiency of secondary crushing, скрининг, and milling circuits.
Elevated Operational Costs: Frequent equipment interventions for unclogging, part replacement, and managing inefficient flow directly impact your cost per ton.

Центральный вопрос: how can you create a more stable, continuous, and costeffective flow of raw limestone from the face to the primary crusher?

2. ОБЗОР ПРОДУКТА

The solution is a HeavyDuty Apron Feeder specifically engineered for limestone mining applications. This robust material handling system is designed to absorb the impact from large haul trucks or loaders and provide a controlled, continuous feed to your primary crusher.

Операционный рабочий процесс:
1. Impact Absorption: Dumped material from a haul truck (до 100+ тонны) lands directly onto the feeder’s overlapping steel pans.
2. Контролируемая добыча & Транспортировка: The heavyduty crawler tractor chain assembly drives the pans forward at a regulated speed.
3. Предварительный скрининг (Необязательный): A grizzly section can be integrated to allow fines to bypass the crusher, increasing overall system capacity.
4. Steady Feed Discharge: Material is consistently delivered into the primary crusher at an optimal rate determined by plant capacity.

Область применения & Ограничения:
Объем: Ideal for primary feeding applications directly from quarry haul trucks or large wheel loaders in hightonnage limestone operations. Suitable for both stationary and semimobile crushing plants.
Ограничения: Not designed as a longdistance conveyor; optimal for shorttomedium length installations (typically up to 30 метры). Requires a solid foundation due to significant weight and dynamic loads.
