1. ОТКРЫТИЕ С УПРАВЛЕНИЕМ PAINPOINT

Are you facing persistent bottlenecks in your gold recovery circuit due to inconsistent ore liberation? Operational challenges with traditional crushing and grinding methods directly impact your bottom line. Учитывайте эти распространенные болевые точки:
Низкие темпы восстановления & High Tailings: Inefficient particle size reduction leaves gold locked within host rock, leading to recoveries below target and valuable material lost to tailings dams.
Чрезмерное время простоя & Обслуживание: Частая смена вкладышей, выход из строя подшипников, and unplanned stoppages in your comminution process halt production and inflate maintenance labor and parts costs.
Высокое энергопотребление на тонну: Старше, inefficient milling technology consumes disproportionate power for the grind achieved, making energy one of your largest uncontrollable operational expenses.
Непостоянный размер помола: Variable feed characteristics lead to an unstable product size, overworking downstream concentration equipment like cyanidation tanks or gravity circuits and reducing their efficiency.

Ваша деятельность нуждается в надежном, proven solution to enhance liberation, reduce operating costs, and stabilize your milling circuit? The industrial Chinese Stamp Mill represents a timetested engineering approach refined for modern mineral processing demands.

2. ОБЗОР ПРОДУКТА

The industrial Chinese Stamp Mill is a gravitydriven, mechanical crushing and grinding mill designed for the selective liberation of freemilling gold from quartz and other host rocks. Its core function is to repeatedly crush ore via heavy, mechanically lifted stamps, facilitating efficient gold recovery through subsequent gravity separation or leaching processes.

Операционный рабочий процесс:
1. Введение в фид: РуфМайн (ПЗУ) ore or primarily crushed feed is uniformly introduced into the mortar box.
2. Cyclic Percussive Grinding: Mechanically powered stamps (48 за мельницу) are lifted and dropped in a controlled cycle onto the ore bed within the mortar box.
3. Формирование суспензии & Увольнять: Water is introduced concurrently, создание суспензии. Finely crushed material passes through a perforated discharge screen at the mortar box's front.
4. Concentration Ready Output: Выгруженная суспензия, with optimally liberated gold particles, is directed to shaking tables, шлюзы, or directly to leaching for final recovery.

Область применения & Ограничения:
Идеально подходит для: Свободная добыча золотых руд, pilot plant testing, мелкие и средние горнодобывающие операции (5500 ТПД), and regions with limited grid power availability.
Ограничения: Less effective for refractory ores requiring ultrafine grinding (<100 сетка) or complex sulfide mineralization. Primary crushing to a manageable size (обычно <2") is required ahead of the stamp mill.
