LJ-WL High-precision Trace Scale

LJ-WL High-precision Trace Scale
Product Detailed
1.High measurement accuracy 2.Structure for easy seal 3. installed in the mechanical system, also installed separately


Applied to the continuous feeding system for solid and powder materialsDesign of AC / DC drive for feedingCan set up joint control of the master / slave feeder proportionDesign of vertical mixer bridge damage Measurement accuracy is much better than ± 0.5% Volumetric or gravimetric feeding system 

        Trace weightlessness scale is also known as reduction scale or high-precision weightlessness scale, which is a weighing equipment for intermittent feeding and continuous discharging, as Vector Control is carried out in the hopper, it can achieve high control accuracy, and structure for easy seal. Especially in plastics, chemical, food, detergents and pharmaceutical industries, it is suitable for cement, lime, coal and other fine materials control.


 Trace weightlessness scale is designed with stir, feeder, extended hopper and support structure. Weighing feeder is completed by the two weighing modules. Stir components move the pliable hopper wall to ensure reliable flow from hopper to feeding part. Feeding device is designed as a single screw tube and propeller. In order to adapt the feeding flow and application, extended hopper can be used for different specifications. Weighing module of weighing feeder is formed by sealed precision load column with strain technology, and the column has a set of overload protection, anti-rotation protection and reduced.

       Weighing electronics is installed in the mechanical system, and can be also installed separately.
