Auger Mining In Weathered Hard RockWe are a large-scale manufacturer specializing in producing variousmining machinesincluding different types of sand and gravel equipment,milling equipment, mineral processing equipment and building materials equipment.
A dust collector is a system used to enhance the quality of air released from industrial and commercial processes by collecting dust and other impurities from air or gas.
A bucket conveyor is a mechanical devices used to transport products from one stage to another.
The hammer crusher, also named heavy hammer crusher, crushes by the collisions between high-speed hammer and materials. It has features of simple structure, high reduction ration, high efficiency, etc.
This series screen is always used in processing minerals such as ferrous metals including hematite magnet and nonferrous metals including lead, zinc, gold and silver, etc.
A rotary kiln is a device that supplies tremendous amounts of heat in order to change the chemical composition of an object.
The dryer machine has been mainly used for drying materials with some humidity and granularity in the fields, such as ore dressing, building materials, metallurgy, chemical industry, etc.
Auger drilling is restricted to generally soft unconsolidated material or weak weathered rock. It is cheap and fast. Percussion Rotary Air Blast Drilling (RAB) Therotary drilling riguses a pneumatic reciprocating piston-driven “hammer” to energetically drive a heavy drill bit into the rock. The rotary drill bit is hollow, solid steel and has ~20 mm thick tungsten rods protruding from the steel matrix as “buttons”.

The Denison sampler is designed to recover undisturbed thin-wall samples in dense sand and gravel soils,hardclays, partially cemented soils, or softweathered rock. The sampler consists of a double- or triple-tube, swivel-type core barrel with a nonrotating inner steel or brass thin-wall liner designed to retain the sample during penetration ...

Jul 19, 2013· In contrast in areas where deep moist soils exist, ahand soil augeris usually used to obtain soil samples. Handaugeringdown to a depth of a metre or more is sometimes necessary to obtain a sample from the top of theweathered rock.Soil samplesby this method are almost always moist orwet, so sieving is not possible.

All our pusher legs of the PL100’s are connected to therockdrill via a single port connection. The support legs are suited for narrowminingand made for rough use. The teeth are made from tungsten carbide steel which is much stiffer and harder than ordinary steel. A robust handle makes it easy to carry.

Mining-Mining- Undergroundmining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surfaceminingbecomes prohibitive, and underground techniques must be considered. Counting against undergroundminingare the costs, which, for each ton of material mined, are much higher underground than on the ...

II.RockRoller Bits: These are suitable for hole diameter between 75 mm and 300 mm. Inminingareas these are commonly used for drilling large diameter holes in mechanised quarries. Flushing of the hole with compressed air instead of by water under pressure is the common practice with this type of bit.
