Explosion proof bag weight filler for powders / granulates
Ex 700 series
Collischan GmbH & Co. Kg
At the development phase of the machines, we work closely with our customers which allows us to provide a high level of filling solutions. To meet requirements in accuracy we offer many different weighing load cell systems enabling small tolerance limits to be maintained.
Spezification Ex 700:
Explosive-proof design:
The weigh filler Ex 700 complies with all requirements of electrical systems and their equipment in explosive areas. Depending on customer request we can offer constructions for different zones (0, 1 or 2 and 20, 21 or 22) and temperature ranges up to T6.
Self-optimizing Conrtoll:
The S 700 controls the speed of the vibration feeder with a digital adaptive control algorithm. The parameters (flow behavior, falling height and weight) are automatically measured and permanently checked. The vibrated chute is automatically controlled, based on values for nominal weight, tolerance limits and output, speed is optimized and monitored. Control systems shoots for the target weight as mean value, at the lowest possible dispersion within the tolerance limits specified. Therefore gross and fine dosing can be operated with one vibrated chute and the operator does not have to enter the machine area. .
Rejection of overfilling:
With our special dosing process with pre- and finedosing the rejected material can be set down to about 5% of the general bulk. Therefore down time can be reduced.
