The ball mill sound insulation cover structure and characteristics

The ball mill sound insulation enclosure though no typical heat source, but cans in the collision of Jane long-term friction also can produce certain quantity of heat, also need to ventilation cooling. So the top cover open a vents and matches the muffler. The lower end plate and cover between shaft have crack, lie between the subglottic also often open, don't have to put wind path. This kind of equipment is to heat, the natural ventilation cooling way is enough. The cover of the structure of ball mill for assembly type, the first ball mill around erection channel steel skeleton, and then it into pieces of the cover wall plate assembly in successive skeletons. The upper portion of the cover plate for tile form, all assembly method for bolt coupling fixed, so in the equipment can be easily removed when the overhaul the sound insulation cover. For convenience of homework personnel, in the sound insulation cover body is equipped with 8 group published two groups and the sound insulation window. The group of five for personnel to enter the laryngeal mask for ball mill in related to the operation with, the upper two equipment maintenance special door and a note oil lubrication with little door. Except through the sound insulation window lighting outside, enclosure also equipped with lighting facilities. Since it is the local sound insulation cover, there is part of the equipment in the hood, there is a cover body and the original equipment, the combination of between. Cover board and equipment should be sealed tight between fixed position. The problem is turning parts of the body and cover with more difficult, the rotation axis to cross the ball mill sound insulation cover the board, shall keep a circle gap here. Aperture neither too big. To avoid missing voice sound insulation effect influence; But neither is too small, so as not to cover plate and contact friction between the axis. Sound insulation cover wall the composition of the board from inner to outer is as follows: 3 RRN thick plate, 6 nm thick drain clear stone cotton lint damping layer, 10 (~ en thick rock wool sound-absorbing board, spun glass cloth and 1 mm thick, perforation rate 30% of the principal part of the perforation panel. Cover plate thickness of the total for 11 firm. In the ends of the cover because of the self-contained tank tube end of the gap between less than 100 ram, cover board and not allowed and rotation tank have a contact, and therefore the place between the cover thickness for five (krma. Close to the shaft of the site because operation requirements often remove cover board, so this part of the cover plate is 4 ding m thick panels, with handles, may at any time off.
