Features: Noise reduction Energy-accumulated technology： ● The roller body rigidity minus vibrations and doesn’t transfer cutting vibration . ● Physical greater moment of inertia of the roller body , great cutting force during cutting ,high cutting efficiency. ● High linear velocity, improve the sharpness of diamond blades. Complete sound insulation cover technology： ●The whole configuration acoustic enclosures ,control the noise in the working area between the machines ,reduce the mixing and sympathetic vibration of thenoise between the machines consequently eliminating sympathetic vibration noise. ● Adopted movable Double-layer toughened glass doors. ● Removable top-covers with special rubber insulating strips. Maintanance safety, convenient: ●Working area of the machine is fully isolation with the outside world, effectively prevent negligent injury. ●Minus the noise from 110dB about to 90Db about. ●The noise meet the emission standard, protect the operator health. ●Removed easily down when changing the roller and maintanance.
