The ACS-7007 series plasticizes and disperses polymers such as plastics. The rolls heat evenly and cool down quickly, and a stepless speed control system allows flexible adjustment of the roll friction ratio and roll speed to meet the dispersion requirements of different formulations. The ACS-7007-150 adds water cooling, which can be connected to a municipal water supply or a cold water chiller.

Why choose the ACS-7007 series

Two roll sizesACS-7007-120 has Ø120 × L350 mm rolls with electric heating (4 kW); ACS-7007-150 has Ø150 × L350 mm rolls with electric heating (6 kW) and water cooling.
PLC color touch screenPLC programmable color touch screen to set and display process parameters such as roll temperature and speed.
Dual servo stepless speed controlRoller speed 0–60 r/min from dual servo motors (1.5 kW × 2) with a planetary gear reducer; the roll friction ratio and roll speed are adjustable.
Mirror chrome-plated rollsHigh-hardness chrome-plated rolls with an HRC58–62 mirror chrome surface: uniform heating, smooth, wear-resistant, non-stick and easy to clean.
Manual roll gap with PLC displayRoll gap adjustable from 0–10 mm by handwheel, with a synchronous display on the PLC; suited to different sheet thicknesses.
Pull-rod emergency stopTouching the yellow pull rod with the body or hand triggers an emergency stop and the rolls reverse automatically.
Knee safety doorIn an emergency, pressing the safety door with the knee reverses the rolls immediately.
Emergency stop button panelRed mushroom-head emergency stop buttons with a running indicator light, at multiple positions.

Frequently asked questions

What is the difference between the ACS-7007-120 and the ACS-7007-150?

The ACS-7007-120 has Ø120 × L350 mm rolls and 4 kW electric heating. The ACS-7007-150 has Ø150 × L350 mm rolls, 6 kW electric heating and a water cooling connection. The controller, temperature range, roller speed and roll gap are the same.

What temperature range and accuracy are published?

RT to 300°C with an accuracy of ±3°C, set on the PLC color touch screen.

How is the roll gap set?

By handwheel from 0–10 mm, with a synchronous PLC display.

What safety devices are fitted?

Multiple emergency stop buttons, a pull-rod emergency stop and a knee-operated safety door; the last two reverse the rolls when activated.

What power supply does it need?

AC 380 V, three-phase, five-wire. The customer provides the power connection point.
