High precision mobile belt scale
Chongqing Long has successfully launched an "array belt scale" with an accuracy error of ≤ 0.2% for a long time, and has also developed a "high-precision mobile belt scale".
The "high-precision mobile belt scale" can accurately weigh the entire belt conveyor while it moves, the frame tilts, rotates left and right, and the inclination angle changes. It is maintenance free during use and can maintain a weighing accuracy of ≤ 0.5% for a long time.
Scope of application
◆ Mobile belt scale
Installed on the cantilever of the stacker reclaimer and in situations where the inclination angle of the belt conveyor is variable. Accurate weighing can be carried out while the entire belt conveyor is moving, the frame is pitching, rotating left and right, and the inclination angle changes. Maintenance free operation is required during use, and the weighing accuracy error should be maintained at ≤ 0.5% for a long time
◆ Fabric control
The high-precision mobile belt scale combined with GPS 3D scanning technology obtains the stacking and layer distribution of the material yard, accurately controls the thickness of the material layer in the material yard, and greatly improves the quality of mixed materials.
◆ Floating belt weighing
Suitable for belt weighing with the tail of the belt conveyor installed in the dock moving dock and the inclination angle changing with the water level; Belt conveyor is installed on mobile devices, and various belt weighing situations where the installation status of the belt conveyor changes during weighing.
The mobile belt scale is a belt scale developed on the basis of the array belt scale, which is installed on variable inclination equipment such as stacker reclaimers or mobile docks. The mobile belt scale adopts "three-dimensional attitude tracking compensation technology" and maintains a weighing accuracy of 0.5% for a long time at any inclination angle of -15 to+100 and during -15 to+100 operation.
Main technical features
High precision attitude tracking system
High precision tracking and detection of three-dimensional attitude changes of weighing units during movement, and compensation and correction of the impact of attitude changes on weighing to ensure accurate weighing of belt scales in various motion states.
Accurate compensation technology for sensors
It can overcome the influence of temperature changes in the outdoor environment of the sensor and the impact of sensor zero point imbalance output.
Overcoming the influence of belt tension
The influence of belt tension has been basically eliminated, and there are no requirements for symmetrical amount rollers. There is no accumulation of empty belt.
