The NVS series vertical shaft impact crusher uses the rocks put into the crusher to break themselves against each other. This self-crushing process produces the best grained aggregate on the market today. The high speed impact crushing of the NVS series improves the density of the rock and improves the grain type, so that the minimum formation can be achieved. The output of high quality products at the same time reduce the product moisture, easy to screen.
Working Principle
1. Unique rotor and cavity design, large processing capacity and high sand formation rate, good particle shape, good fineness modulus,FM=2.3 ~ 2.9, low needle flake content, can be controlled within 8%, high packing density.
2. The self-impact and self-lining mechanism between materials reduces the contact between materials and metal, effectively protects the throwing head and other wear parts, avoids damage and premature damage of wear-resistant body, and is conducive to the treatment of too dry or too wet materials.
3. The unique structure of wear-resistant parts reduces the weight of wear parts by 30kg, and more alloy materials are used to increase the service life of wearing parts by 25% and reduce the operation cost.
4. The specially designed transmission structure, the motor base is installed on the bracket, which breaks away from the vibration of the crusher, and the vibration load of the motor is reduced by 60%. Thus fundamentally eliminate the failure of motor block cracking and broken shaft which often occur when the motor block is fixed with the main engine by other manufacturers. At the same time, the transmission of high power is more stable and reliable.
5. The newly optimized material overflow mode ensures that the material overflow can be controlled, and the falling direction is just relative to the high-speed material flow emitted by the rotor, which can make better use of the impact energy and increase the output by 10%~20% without increasing the energy consumption.
6. Special spindle structure and simple dry oil lubrication, to ensure that the spindle and bearing used for more than 6000-10000 hours will not be damaged, bearing adopts FAG brand special bearings, to ensure reliable performance, reduce the user's cost, and convenient supply; We guarantee that in case of quality problems during the warranty period, unconditional free repair or replacement.
7. The ingeniously designed hydraulic control feeding valve ensures the uniformity of the equipment feeding and improves the crushing effect.
8. Optional electric lifting device, anti-vibration sensing device, temperature control sensing device, cumulative startup timing device, PLC control, to ensure the safe operation of the equipment.
9. The ingenious self-circulation design of internal air flow eliminates the dispersion of dust. The dust concentration in the center of the discharge port of the equipment is less than 60mg/m3, and the dust concentration in the environment within 5 meters around the equipment meets the relevant national standards, less than 10mg/m3.
