Belt scale and weightlessness scale are used in industrial batching system,all can be used as quantitative feeding part of batching system,both have their advantages.

一、The product features of belt scale
1. As a dynamic measurement system,belt scale is very stable when in use,and is also easy to operate;
2. The occupied space of belt scale is small,the cost is not high,and is suitable for installing in a variety of forms of conveyors,can be used to measure from the lump ore to the coal to dry powdered materials;
3. No movement or abrasion resistance,small amount of maintenance;
4. Strong steel,small dusty area,to ensure the stability of zero;
5. Resistance lateral force and resistance level are strong;
6. Installation is simple and convenient;
7. The accuracy is up to 1%;
8. System accuracy: ± 0.25% (4 ~ 8 Doto roll),± 0.5% (2 ~ 4 rollers),± 1.0% (1 ~ 2 single idler);
9.  Flow range: 0.1 ~ 2000t/h;
10. Weighing sensor: domestic or imported can be equipped with sensors (alloy or stainless steel type);
11. Belt width: 500、650、800、1000、1200、1400mm,etc.;
12. Belt speed: 0.10 to 4.0 m/s   belt angle: 0 to 18;
13. Belt model that can be equipped with: TD72、TD75、QT80、QT85 and other belt rack.

二、The batching system features of weightlessness scale
1. The measurement control accuracy is very high;
2. Can be used in a continuous or  batch type feeding needs;
3. Suitable for powder,granule and other bulk materials;
4. The whole system is sealed,so it will not pollute the environment;
5. Manual or automatic mechanical packing all can be fine;
6. When packing,the speed must be fast enough;
7. With explosion-proof function;
8. You can use the multiple devices with the multi machine system connected distributed batching control system.

The majority of users in the selection of belt scale or weightlessness scale,should be determined according to the actual situation,the specific materials and control requirements.So it can meet the production requirements.
