For modifying asphalt with SBS the key is a high‑shear rotor‑stator colloid mill sized for your throughput and polymer form (granules, powder or liquid). For medium to large continuous production where you need to grind and disperse granulated SBS into hot bitumen at industrial throughputs, a heavy‑duty unit such as the CLM‑40.2 is a common choice — it’s built for SBS grinding, high shear and elevated process temperatures and can be supplied as part of a new plant or retrofitted into an existing line. For general‑purpose, high‑shear polymer‑modified bitumen work across a range of products the CLM‑200.2 is a versatile option, while the smaller CLM‑8/16 is appropriate for inline homogenization/emulsification and lower‑rate SBS grinding tasks where adjustable gap and robust rotor/stator tooling matter.

If you want a turnkey continuous modification solution (controlled heating, mixing, dosing and circulation) consider a dedicated continuous modification unit rated for SBS handling — these are sized for moderate throughputs and simplify integration and process control. Ultimately select the mill by required capacity, whether you run continuous or batch, the physical form of the polymer, temperature and pressure needs, and how you’ll integrate heating and dosing; discuss your exact throughput and process temperatures with the supplier so they can match the correct CLM model or a continuous unit to your plant.
