Hand-held pneumatic rock drill
Pneumatic rock drill is ideally for development and stoping applications where high drilling speed is required. There are three primary variations include jackleg, stoper and sinker for practical work needs.
Air hoses, less than 1 inch in diameter, are not being used in mine compressed air distribution system. Contact us for reliable suggestions.
Suggestions for youThe air hose is responsible for transferring the power of compressed air to various pneumatic tools. In the compressed air distribution system, the air hose specifications required for different sizes of air compressors are also different.

Mining is a vast global industry focused on a wide variety of natural resources. Through mining, people can extract the most valuable, useful and beautiful natural resources on the earth for use in all areas of our lives. The modern mining process relies on a variety of mechanical equipment, most of which are powered by air compressors. Compressed air will be distributed to each machine through the proper air hoses. In order to achieve efficient operation, the discharge pressure must be high enough to deliver the compressed air to the machines at the a certain pressure. Special needs to be pointed out that the use of undersized hose in the compressed air distribution system is the primary cause of low air pressure. As a manufacturer, we will give professional advice according to our years of practical experience.
The appropriate compressors used at mines are of positive-displacement types. Reciprocating compressor, the air is compressed by a piston in a cylinder, is the most common choice of mine managers.

Mucking machines
Mucking machines, powered by a small compressed air, are designed for loading the broken rock in underground mining.
Pneumatic chain hoists
Mining air hoists are powered by the safe and reliable compressed air. They are specifically designed for pulling and lifting operations in mining and tunneling industries.
Air scraper winch
Air scraper winch adopts compressed air as power to diver the air motor. It is used to move the ores at the underground mining or open air.
