More about silo and discharge systems

PVC – the basic raw material

Outdoor silos with filter The PVC powder is stored in the outdoor silos. Large-area filters ensure clean ventilation when filling the silos. Pressure monitoring systems protect the silos from damage caused by overpressure or underpressure.

The existing silos at the Kurtatsch plant will continue to be used for the storage of PVC powder. Modern AZO filters and pressure monitoring systems reliably protect the plant. New suction hoppers with suction nozzels ensure trouble-free discharge from the silos into the conveying line.

Safety thanks to retrofitting the existing outdoor silos for PVC

AZO vacuum weighing systems

Multiport valve The multiport valve brings the individual conveying lines from the silos and big bag stations together at the conveying scales.

Pneumatic vacuum weighing systems with conveying scales are the solution for the economical automation of precisely weighed large and medium-sized components. The central elements of the multi-tube system are the conveying scale and the multiport valve. A conveying line leads from each product feed point to the multiport valve, which is connected to the conveying scale. As a result, the product overrun is very low, which enables high accuracy.

Discharging, dosing, conveying, combining and weighing. Many process steps in one system with special advantages:

• Safety thanks to sophisticated technology • Height and space-saving

• High weighing and dosing accuracy • Clean and simple product infeed • Consistent product quality • Fast recipe changes • Precise coordination of control and process technology

Convening scale The perfect system for transporting large and

medium-sized components directly above the mixer and weighing them precisely.
