Product Description
The 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.

Brief Introduction
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.
What is the Most Commonly Used Air Compressor in Mine?
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.
Main Machines Powered by Compressed Air
A mine worker is operating with a stoper drill.Hand-held
pneumatic rock drillPneumatic 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.
A used mucking machine with black air hose.Mucking
machinesMucking machines, powered by a small compressed air, are
designed for loading the broken rock in underground mining.
There are two pneumatic chain hoists with different
styles.Pneumatic chain hoistsMining 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.
There is an air scraper winch on the ground.Air scraper
winchAir 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.
A picture show the ventilation pipeline of the underground
mine.BlowersBlowers have a wide range applications in underground
minging industry. Such as dust control, cyclone solutions,
ventilation and cooling. They act as different types of large
vacuum cleaner to move dirt from the job site.
Material Selection
Where there is an air compressor, there will be one or more
air hoses.
Rubber
We adopt quality EPDM (Ethylene Propylene Diene Monomer), SBR
(Styrene Butadiene Rubber) or NR (Natural Rubber) as tube material.
Then reinforced by high strength polyester or synthetic yarn.
PVC
PVC pneumatic hammer hose are available in polyester yarn
reinforced type and high-pressure double polyester reinforced
type.
