When selecting a quantitative belt scale, it is essential to understand its application points!

A quantitative belt scale is a device for short-distance material transport, dynamic weighing, and quantitative control between two points in production. Its application is mostly a customized solution based on actual production needs, with hardware structure and software functional configuration tailored to the site environment. Therefore, users must clarify its application points before choosing a quantitative belt scale.

When providing requirements to the manufacturer, users should first specify the specific parameters of the actual application site, including:

· Materials: name, moisture content, temperature, granularity, and bulk density.

· Flow range: maximum, minimum, and normal flow rates per hour.

· Application conditions: actual wiring distance from the scale body to the electric control cabinet, and the total number of quantitative belt scales in the control system.

· Hardware: whether the shell needs to be enclosed or semi-enclosed.

It is crucial to honestly inform the manufacturer of the actual application parameters, especially the maximum flow rate, bulk density of materials, and distances. Inaccurate distances can prevent the installation and application of the belt scale. If the actual flow rate significantly exceeds the device's maximum flow rate, it may cause damage.

 Conversely, if the actual flow rate is much lower, it may result in inaccurate measurements, rendering the scale ineffective. The bulk density affects the calculation of material conveyance per unit length of the belt scale.

If the proposed bulk density is high, the speed of the frequency converter output must be increased accordingly. Insufficient allowance may prevent reaching the maximum flow rate. In summary, the parameters of the quantitative belt scale must align with the actual site conditions.

Excessive belt speed may damage the belt or cause unstable material cross-sections, affecting equipment stability and measurement accuracy.

Generally, the belt speed should not be too fast. The belt speed also relates to material characteristics. When the material mixture contains a large amount of fine materials, the belt speed can be appropriately increased.

The width of the quantitative belt scale closely correlates with factors such as material flow rate, bulk density, granularity, and fluidity. If the belt is too wide, the material layer will be thin, the belt load will be small, and the discharge will be unstable, with greater belt stiffness. If the belt is too narrow, the material layer will be thick, the belt speed will be fast, and the material flow will also be unstable. Besides belt width, if the material is fluid and prone to spilling, corresponding material retainers can be configured.

The choice of belt material depends on the material characteristics. For high-temperature materials, heat-resistant belts should be selected; for corrosive materials, corrosion-resistant materials and components should be chosen; for highly abrasive materials, belt wear must be considered, as well as the wear at the material inlet.

The center distance of the quantitative belt scale relates to its width, i.e., its length. When the belt is wider, the center distance should be appropriately increased. For materials with good fluidity, the center distance can be increased to ensure uniform and stable material flow through the weighing area.

Of course, apart from these application points, there are many other details to consider. However, users must inform the quantitative belt scale manufacturer of the actual site conditions and needs. The manufacturer will then provide a reasonable and suitable solution based on the user's requirements.
