The working principle of a grid type ball mill is that the holes on the grid lining plate are arranged obliquely, and the width of the holes gradually expands towards the discharge end, which can prevent pulp backflow and coarse particle blockage. The slurry flows into the fan-shaped chamber through the pores on the grid lining plate at the lower part of the ore discharge end, and then rotates to the upper part of the cylinder and is discharged along the channel. The hollow shaft neck is embedded with a wear-resistant inner sleeve, and one end is made into a trumpet shaped blade to facilitate guiding the slurry out of the mill along the blade. Due to the fact that this type of mill slurry is discharged through a grid plate discharge device, it is called a grid ball mill.
There are many models, high production capacity, and strong functions of ball mills. Understanding the model and production capacity of ball mills before investing in this equipment is more helpful for users to purchase suitable equipment. Grid ball mill equipment is a popular model among grid ball mills, with a simple structure, good grinding effect, and long service life. The grid ball mill has a large number of users and production capacity, but there may be high noise. Here is a brief explanation of the treatment method for high noise in lattice ball mills.
The noise of lattice ball mills is one of the sources of industrial noise, and the noise control of lattice ball mills is also a common project. The noise of lattice ball mills is mostly transmitted through air vibration, and Fodamon engineers suggest using soundproof enclosures or soundproof rooms. The analysis of noise reduction methods for lattice ball mills is as follows:
Ⅰ. The soundproofing cover of the lattice ball mill is divided into global soundproofing and local soundproofing, with local soundproofing being smaller than global soundproofing.
Ⅱ. The soundproof cover is to cover the entire grid ball mill, and the material of the soundproof cover is generally made of 2-3 mm thick steel plate, damping material, sound-absorbing cotton, galvanized perforated plate, etc.
Ⅲ. Material and personnel access channels need to be reserved above the sound insulation cover. To achieve sound insulation, it is necessary to install double doors and windows at the same entrance and exit, as well as single access doors on both sides.
Ⅳ. The grid ball mill generates heat during operation, so ventilation channels should be reserved. Generally, ventilation openings are set up on the side and on the top. To ensure sound insulation, silencers are required for the ventilation openings.
Ⅴ. Replacing manganese steel lining with rubber lining can change the spectral characteristics from high frequency to low frequency.
Ⅵ. If conditions permit, soundproof rooms can be designed to concentrate the lattice ball mill into soundproof rooms designed for the lattice ball mill. The effect will be better than soundproof covers, which can effectively solve the problems of monitoring, indoor heat dissipation, and maintenance during the operation of the lattice ball mill.
