Seven method Raymond mill noise control

With the vigorous development of milling industry, people milling equipment to increase demand, Raymond mill in the market share of an increasing proportion of weight. (Raymond mill) mill production line as the most important equipment during the operation of the mill, often inevitable emergence of machine noise problem, then, how to effectively control noise Gives the operator and nearby residents harm? Now after a small series of summary data, noise control method will now be summarized as follows:
1, reducing bearing noise
(1) controlling the shape and position tolerances journal roller bearing housing bore.
(2) Install an elastic damping bushings, to reduce noise it has a more significant effect.
(3) reinforcement of the housing bore at the seat wall, bearing wall near the base should be thickened or stiffened to reduce vibration thin wall.
(4) to ensure good lubrication, reduce noise.
2, improved feeding mechanism
(A) feeding to automatically adjust the size of the door opening, to maintain uniform feeding, thereby reducing noise.
(2) After processing speed roller pulley subject to balancing test, balancing error is smaller, less vibration.
3, to reduce the noise of the body
(1) the upper part of the body using welded steel cast iron lower part of the bracket structure, and is conducive to maintaining and rolled away from the constant noise reduction.
(2) Mill fiberglass cover, add some sound-absorbing material within the housing, thus reducing noise.
(3) the speed of the roller drive gear should be used with a wedge, with low noise.
4, to improve the structural design of the grinding brush
From the next state, automatically leave the grinding brush roll body, reducing the friction between the roller and reduce noise grinding brush.
5, the control from the transmission
(1) plus provided a barrier to prevent the spread of noise, or the use of natural form, such as hills, slopes, trees, bushes or afraid of loud tall buildings or additions or structures.
(2) the use of directional characteristics of the sound source to control noise; to reduce the impact on the environment.
6, the contact person for protection
(1) personal protection, such as wearing earplugs, earmuffs anti-noise helmets and other supplies.

(2) to take workers rotation operations, reduce time-to high-noise environments working time; take silencer, sound absorption, sound insulation and other measures.
7, workers regularly exposed to noise and hearing general health check
(1) found a high frequency hearing persistent decline and more than the normal fluctuation range, should be removed as soon as possible noise operation positions.
(2) when a new pre-employment medical examination of workers, where the sense of hearing loss and significant cardiovascular, nervous system organic diseases, should not engage in a noisy room to rest;
(3) in high-noise environments minimize working time;
(4) regular workshop noise monitoring, noise and serious harm of factories, workshops carry out health surveillance, and promote its active measures to reduce noise, noise to comply with hygiene standards.
Research shows that when noise is 90 decibels, people retina rod cells distinguish brightness sensitivity began to decline, to identify low-light reaction time; when you reach 95 decibels, the pupil will expand; at 115 decibels, the brightness of the eyes to light adaptability will reduce 207. In addition, long-term noise exposure, the most prone to eye fatigue, eye pain, blurred vision and tearing and other phenomena.
Therefore, in their daily work must be appropriate control of noise, so your body produces its unnecessary harm!
