Our line of cutting mills includes models which reliably process: soft, medium-hard, elastic, tough and, fibrous materials. All models are based on the same grinding geometry and feature. Depending on which model, our cutting mills may feature: Variable speed and adjustable in a range from 700- 3000 revolutions per minute A fixed rotational speed of 1500 … Read more

Screw conveyor

The screw conveyor consists of a spiral blade attached to a shaft which revolves in a horizontal or inclined trough. Material fed into one end of the trough is pushed toward the other end by the rotating spiral. The shaft is mounted on bearings at each end and also in the middle, if the conveyor … Read more

Mine Water Chemistry – Is Process Water Hurting my Results

Mines are recycling more water than ever before. This is a logical response to water stresses (see our article on Water Balances).  However, there is a risk associated with the good stewardship of water.  Deleterious elements and compounds can concentrate in recycled mine water as it is recycled again and again, and these deleterious elements … Read more

Mineral Jig Concentrator

The Duplex Mineral Jig Machine belongs to gravity concentrating device that separates material based on differing densities of the material. The Jig is widely used in concentration of heavy minerals such as tin, gold, tungsten, manganese and barite. The 911MGTK-XCT Laboratory Mineral Jig Machine is an ideal instrument for research of beneficiation of ferrous metal … Read more

Gold Amalgamator

Grinding and amalgamating are practical and satisfactory methods for treating gold-bearing concentrates or black sands or for cleaning up a mill. The gold is brightened and made more amalgamable. The tailings might be rich enough for cyaniding. Figure 137 shows an amalgamation barrel. Laboratory ball- mills and the smaller of the ball-mills (amalgam gets behind … Read more

Lime Slaking Mill

A horizontal ball mill can be used as in a lime slaking circuit just as well as a vertimill. Some operations apply the raw quicklime directly to the ore on the belt moving toward further crushing or grinding. In this application, it is necessary only to have a suitable lime storage tank with a live … Read more

VSI Crusher Vertical Shaft Impactor

In a vertical shaft impact crusher, the aggregate feed is introduced into a shoe or pump spinning on a vertical axis. The aggregate feed is thrown centrifugalLY against a series of anvils, pockets of aggregate particles (i.e., autogenous), or a combination thereof. Vertical shaft impact crushers produce a small reduction ratio and arc often used for … Read more

A high quality spiral sand washing machine for you sand wash plant.  The spiral sand washing machine (XL series) is able to wash and separate the soil and other impurities in sand and gravel aggregate. I he enclosed structure, adjustable overflow weir plate, and reliable transmission parts increase the cleaning and dehydration effect, which can … Read more

Dense Medium Cyclone

From the early 1960’s until the mid 1980’s, dense medium cyclone circuitry design technology did not change appreciably. The basic design, which was both highly flexible and highly efficient, was consistent with technology developed by the Dutch State Mines (“DSM”) in the mid 1940’s. During this period, the “typical” dense medium cyclone circuit was designed … Read more
