试验室SPB200型拍击式振筛机技术参数
Technical Parameters of laboratory Beating standard screen
系在SPB-200拍击式振动筛机的基础上改进的，改进后既能具备原型技术性能，又能装夹套筛方便灵活，夹紧牢固，并能自动停车，根据用户需要，可筛分多种特性的产品。
This kind of equipment is improved on the basis of SPB-200 beating standard screen. The improved type not only has the technical functions of its prototype, but also can clamp sieve sets tightly as well as stop automatically. It can sieve products with multiple characteristics according to user needs.

三、工作原理：
III. Working Principle
经过机械传动，将旋转运动转变为筛板的往复运动，从而使筛具亦作同步摆同，同时配以重锤的周期迫击，这样在一定震动的频率下达到筛具内物料的按网目分样之目的。
Through mechanical drive, rotating motion changes to reciprocating motion so that the sifter also swings synchronously. With also periodic strike from the hammer, the materials in the sifter can be successfully separated according to meshes under certain vibration frequency.
1、开机前必须加油10公斤，注意电机外壳上所示的箭头方向是否一致，禁止反转。
1. Make sure to add 10kg of oil before starting the machine; and check if the directions of arrows indicated on the motor casing are the same. Never invert it.
2、将装有试样的筛具（8）置于下筛盘（7）上，调整升降托架（10）使筛具紧卡在筛盘（9）与下筛盘（7）之间。
2. Put the sifter (8) which contains sample onto the lower sieve tray (7); adjust the lifting bracket (10) to get the sifter to be clipped firmly between the sieve tray (9) and lower sieve tray (7).
1、调整升降托架，启动蝶形紧螺母（11）
1. Adjust the lifting bracket and start up the wing nuts (11);
2、注意保持箱盖（6）上平面的油膜长存，以免产生锈斑。
2. Please keep the persistence of oil membrane on the surface of cabinet cover (6), to avoid rust;
3、经常注意运动件的滑润，定时加油，以延长使用寿命。
3. Lubricate the moving pieces frequently and oil it regularly, for extending the service life
4、整机须安在固定位置上，减少摇动。
4. The whole machine shall be installed in a fixed place to reduce vibration.
