The Puzzle Brought by the Noise Problem of Mining Machinery

Recently, the noise problems brought by the industry of mining machinery have become one question influencing the whole city, because all of the human beings hope to live in the environment which is quiet and peaceful.
Ball mill is also called coal mill or tube mill, mainly composed by the large tank barrel, gear, bearing and motor. When operate the ball mill, these components will make different noise, and the primary and secondary sound source position is also different.
As the domestic economy continues to develop, large production ball mill are constantly required in domestic and our country actively introduces advanced crushing production line equipment, so the advanced system of sand and stone equipment quickly enters into the country; through years of research and development and innovation, Hongxing machinery company introduced advanced wear large ball mill equipment, which is specialized for various hard stone crushing, such as pebbles, river pebbles, granite, granite, quartz, limestone and other extra-hard materials, widely used in sand plant, concentrator, stones, coal plants, mills and other major domestic projects.
Energy ball mill noise is made by the colliding of grinding steel balls, material and liner. This noise is a mechanical noise, radiating outward from the surface of the tank. As to the same type of energy ball mill and sand production line, when the crushed materials or the number of feed ranging are different, the noise generated by the operation is quite different.
Analysis measurements of the sound source of energy-saving ball mill a unit show that, the large cans is the main noise source; gears, bearings, sand making production line transmission device and motor, relatively speaking, belong to the secondary sound source. Considered from the point of view of the sound power, sound power radiated by the large cans is dominant, while other parts of the sound power radiation is significantly lower.
Then the way to solve the noise problem has become the most urgent matter for the manufacturer producing the mining machines.As the professional manufacturer of complete sets of mining machinery, such as hammer crusher,sand maker, Henan Hongxing is always doing the best in products and service.
