1. ОТКРЫТИЕ С УПРАВЛЕНИЕМ PAINPOINT

Are you facing escalating operational costs and unpredictable throughput in your gold processing circuit? Для руководителей заводов и инженерных подрядчиков, the comminution stage—particularly with a Chinese stamp mill for gold mining—often presents critical bottlenecks. Общие проблемы включают в себя:

Большие простои при обслуживании: Frequent wear part replacement on traditional stamp mills leads to unplanned shutdowns, directly reducing annual processing hours and revenue.
Непостоянный размер помола: Variable feed material can cause uneven pulverization, compromising gold liberation and recovery rates in downstream cyanidation or gravity circuits.
Чрезмерное потребление энергии: Старше, inefficient drive systems and heavy mechanical components result in disproportionately high power costs per ton of ore processed.
Трудоемкая операция: Manual feeding and monitoring requirements increase labor costs and introduce potential for human error in process control.
Ограниченная масштабируемость & Контроль: Basic mechanical designs offer little flexibility to optimize performance for varying ore hardness without significant mechanical adjustment.

How do you reduce total cost of ownership while ensuring consistent, reliable ore preparation? Решение заключается в модернизации, precisionengineered stamp mill technology designed for the demands of contemporary small to mediumscale gold mining operations.

2. ОБЗОР ПРОДУКТА

This product line refers to modernized, heavyduty mechanical stamp mills engineered for the primary crushing and fine grinding of goldbearing quartz ores. Designed as a robust alternative or upgrade to historical models, these mills are built for continuous duty in hard rock mining applications.

Операционный рабочий процесс:
1. Контролируемая подача: Рунофайн (ПЗУ) ore is fed via a regulated hopper and feeder system into the mortar box.
2. Precise Pulverization: A camshaft lifts cast iron or steel stamps (обувь) in a sequenced cycle, dropping them under gravity onto the ore bed within the mortar box.
3. Непрерывный разряд: Finely crushed material passes through a perforated screen plate at the mortar box's end, allowing liberated gold particles to report to downstream recovery processes.
4. Обработка суспензии: The discharged pulp is typically channeled to shaking tables, центробежные концентраторы, or directly to leaching tanks.

Область применения & Ограничения:
Идеально подходит для: Smalltomedium scale hard rock (жила) gold mining operations; processing centers handling 10100 тонн в день; regions with reliable access to mechanical power but limited grid infrastructure.
Хорошо подходит для: Quartz vein material where gold is finely disseminated and requires thorough liberation.
Ограничения: Not optimal for highclay or alluvial (россыпь) депозиты; requires consistent ore sizing (<2 дюймы) для оптимальной работы; not a standalone solution, must be integrated into a full recovery circuit.
