　　YKR/ZKR系列振动筛选取世界先进的设计理想，拥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，可齐全代替国表进口产品。

　　产品特点

　　1.激振器选取表置式块偏疼结构，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情况大为改善。相对轴偏疼振动器提高了激振力，减轻了激振器沉量，方便维批更换。激振器之间用万向节联接，拥有使用装置更换矫捷、寿命长的利益。

　　2.侧板与加强梁、横梁之间的衔接全数选取钢结构用相剪型高强度螺栓（抗拉应力为900mpa）迸酌环槽柳钉（抗拉应力为300mpa）联接强度高，易更换，同时预防了因铆接不当而将联接螺栓孔挤出微裂纹的景象。

　　3.YKR圆振动筛电机是通过传动轴承座与激振器联接，电机的寿命得到保障，同时也能够通过更换皮带轮来方便的调节振动筛频率。

　　4.YKR大型圆振动筛选取国际先进水平同步带结构，和五齿轮同步器相比，结构单一，沉量轻，维建方便。

　　5.筛机频率、振幅、装置角度都可调。选取挠性联轴器，电机不参振，拥有使用寿命长，对筛机装置前提要求低，筛机运行安稳、振动轨迹好的利益。

　　6.筛机支持选取橡胶弹簧，与金属弹簧相比，拥有使用寿命长、耐侵蚀，过共振区安稳，噪音低，对地基冲击幼蹬着点。

　　7.NJ激振器的轴承座及偏疼块设计紧凑，这种设计使得NJ激根器不仅占有巨大的激振力，同时能够整体的装置于侧板内孔中，免去了更换单个轴承的麻烦，整体拆装更换只需一幼时，降低了守护成本。

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.
