ykr/zkr系列振动筛采用世界先进的设计理念，具有国际先进水平的振动器和超强结构的筛箱，是矿山筛分设备最佳的选择，可完全替代国外进口产品。
产品特点
1.激振器采用外置式块偏心结构，每块侧板的激振器引起的合力通过侧板厚度中心侧板只受拉\压力，不受弯矩侧标和筛箱受力状况大为改善。相对轴偏心振动器提高了激振力，减轻了激振器重量，方便维修更换。激振器之间用万向节联接，具有使用安装更换灵活、寿命长的优点。
2.侧板与加强梁、横梁之间的连接全部采用钢结构用相剪型高强度螺栓（抗拉应力为900mpa）比用环槽柳钉（抗拉应力为300mpa）联接强度高，易更换，同时避免了因铆接不当而将联接螺栓孔挤出微裂纹的现象。
3.ykr圆振动筛电机是通过传动轴承座与激振器联接，电机的寿命得到保证，同时也可以通过更换皮带轮来方便的调节振动筛频率。
4.ykr大型圆振动筛采用国际先进水平同步带结构，和五齿轮同步器相比，结构简单，重量轻，维修方便。
5.筛机频率、振幅、安装角度都可调。采用挠性联轴器，电机不参振，具有使用寿命长，对筛机安装条件要求低，筛机运行平稳、振动轨迹好的优点。
6.筛机支撑采用橡胶弹簧，与金属弹簧相比，具有使用寿命长、耐腐蚀，过共振区平稳，噪音低，对地基冲击小等优点。
7.nj激振器的轴承座及偏心块设计紧凑，这种设计使得nj激根器不仅拥有巨大的激振力，同时可以整体的安装于侧板内孔中，免除了更换单个轴承的麻烦，整体拆装更换只需一小时，降低了维护成本。
ykr/zkr vibration screen is designed and developed with the world latest technology. it is the best choice for screening equipment in mining industry, ykr/zkr vibrating screen is incorporated with the most advanced vibrating exciter and high strength screening frame.
features
1.the exciter is designed with external eccentric block structure, both side forces through the mid-depth of side plate, side plate is only in tension\pressure, the force condition of the side plate and the screen body is greatly improved. this exciter increases the excitation force, reduces parts weight, it is also easier to replacement. the exciter is connected with universal joint, it has the advantages of flexible installation, and long life.
2.the connection between side plate and beams are torsion shear high strength bolts (tensile stress is 900 mpa), it has a higher strength and easier to replace than ring groove rivet (tensile stress is 300 mpa), at the same time, it avoided micro crack phenomenon due to improper riveting to squeeze the connecting bolt holes.
3.the motor of ykr screen is connected by the transmission bearing seat and the exciter, the life of the motor is guaranteed, and the frequency of the vibrating screen can be adjusted-easily by changing the pulley.
4.the ykr screen is used the international advanced horizontal synchronous belt structure. compared with the five gear synchronizer, the structure is simple, lighter and easy to maintain.
5.the screen frequency, amplitude and installation angle are adjustable. the motor avoid vibration by flexible coupling, it has the advantages of tong service life, low installation requirement, stable operation and excellent vibration track.
6.the rubber spring is used for supporting of the screen, compared with the metal spring, it has the advantages of long service life, corrosion resistance, stable resonance region, low noise and small impact on foundation.
7.the nj exciter's bearing seat and eccentric block are compact, this design makes nj exciter has the huge vibration force, and it also can be installed in the inner hole of the side plate to eliminate trouble of changing single bearing. it takes only one hour to remove the whole assembly, reducing maintenance costs.
