Continuous operation weighers DVND

USING

The continuous operation weighers DVND-650 are used for dosing powder and fine materials and can be used in different brunches of industry. Dosing materials – loose batch components with angle of friction no more than 60, humidity no more than 5 and with particle size no more than 30 mm. Output in fact depends of properties of transport material, transport conditions and specifies during de-sign process, there is output for material with density 1,75 t/h.

Weighers DVND-650 consist of the following devices:

– feeding device (vibrating feeder or screw)
– small size belt conveyor
– weigher cap (DVND-650/PV8S-0,5/1,2 and DVND-650/PV8S-0,5/1,6) or junc-tion pipe with flexible connector (DVND-650/SH-0,25/1,5)
– hinged conveyor carriage
– strain measuring suspender
– suspension frame
– control device

Feeding device with controlled output deliver the material on the belt of weighing conveyor. Indicator of speed (encoder), connected with movable pulley axle tree, gives im-pulse signal during tape transport on definite value. Strain measuring suspender test weight of conveyor with material and give the present meaning of weight load in control device to count weight of material, passed through conveyor. Container and scaling factor of weighing device installs during weigher settings in-stallation (calibration check and test). During the use of weigher for supplying certain dose of material, the concrete or-der is supported. This order allows managing the value of allowance, which provide measuring error elimination connected with loosing of material when the feeding device is switched of.
