Crushing and Grinding Wet & Sticky Ore

In the handling of wet, sticky ores such as encountered in tropical areas having distinct dry and rainy seasons, the crushing plant is a section of the mill which must be planned very carefully. Unless this is done, crushing becomes a constant source of trouble resulting in lost production and high milling cost. In some areas rainfall is high for prolonged periods.Онлайн-запрос

Mining Technology in the Nineteenth Century | ONE

Miners used mechanical crushing and grinding machines to break up ores for further processing. Early miners used Mexican arrastras or stamp mills, which reached their peak in the late nineteenth century, to crush ores into sand-size particles. Before going to stamp mills, ores often went through rock crushers, which were like nutcrackers.
