Collin® laboratory roll mils are machines intended for discontinuous mixing, kneading and plasticizing. These are important processing operations that can be used to test the quality and processability of plastics and elastomers . Whether commodity resin, high-temperature material or other specialty such as a ceramic formulation – roll mills from Collin® set the standard for precision and reliability.

Type W 100 T

Bench-top roll mills are designed for testing small batches. The primary users are research and educational institutions as well as industry. Rolls are 100 mm in diameter with a width of 120 mm. Batch weights up to 50 g can be processed.. As a down-stream take-off device, they are ideal for finishing extruded film.

Type W 110 EP and W 150 EP

Testing roll mills from Collin® are used primarily for routine testing in industry. Leading manufacturers of PVC, polyolefins , compounds, pigments and masterbatches use these high-quality mills to ensure the quality of their products . These machines also find regular use in production of high-quality plastic products.

Type W 110 AP and W 150 AP

Automatic testing roll mills from Collin® are especially useful when maximum reproducibility of test results is required. Auto- matic processing ensures that results are independent of the operator.

Type W 110 G and W 150 G

These roll mills are equipped with high-torque drives for processing elastomers .

Type W 150 M, W 200 M and W 250 M

These high-quality testing roll mills from Collin® are character- ized by their very sturdy construction. This provides the basis for precise and reproducible process parameters. An ergonomic touch screen control system regulates the process, records the process parameters and offers a variety of options for evaluat-ing the data collected. This makes the machine indispensible when developing high-performance resin formulations today.

Type W 150 MG, W 200 MG

The sometimes very high viscosity of elastomers requires roll mills with more powerful drives, gearboxes and ancillary devices. These MG Types offer a level of automation similar to that found on the above testing roll mills.
