Gravimetric Blenders - SGB

Features

Auto calibration function is performed every time after each material weighing with dosing rate to ensures best proportioning accuracy.

Up to 1000 recipes can be stored.

An optional movable hopper with a quick air connector is available with the SGB-3 series, which is convenient for changing masterbatches, cleaning and maintenance.

The quick detachable mixing tank and blade make it convenient for disassembling and cleaning.

The Ethernet communication function can realize centralized connecting and monitoring with the main process machine.

The built-in conveying function can operate with the vacuum generator SVG and the central hopper receiver SHR-U-ST.

When unit reaches the preset batch, the unit can stop automatically.

The power-off memory function, it can resume the work process as before after restart, which can save the metered material.

Software upgrades can be achieved via USB auto program updates.

The 7’’ color touch panel can be record the production data and alarm logs, and supports USB one-click export function that is convenient for production analyzing.

Support sandwich metering mode to solve the problem of differences in the accumulation specific gravity of masterbatch materials.

The unit supports the function of regrind material auto-compensation.

Support multiple languages including Chinese, English, Spanish, French, Vietnamese, Japanese, and Polish.

Material hopper low-level sensors can provide an early alarm when materials are low. Add “LS” at the end of the model code.

A special metering valve, including a bridge-breaking device. It is for flake or irregular material while the diameter is less than 12*12*12mm/0.47*0.47*0.47 inch. Add “FF” at the end of the model code.

The micro-pulse metering valve (suitable for SGB-1 series model) is optional, which is suitable for receipt ratio from 0.5% and 1%, and add “MF” at the end of the model code.

The bridge breaking device is optional, and add “MB” at the end of the model code.

For high-temperature materials processing above 80℃ and below 120℃, add “H” at the end of the model code.

SGB series with floor stand. Add “ GS” at the end of the model code.
