Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement needs that require the use of an open mill, it is recommended to match the production scale based on key technical parameters such as mixing capacity, roller size, and power. For example, a two roll open mill is suitable for small laboratories, while large-scale rubber processing requires the selection of large equipment with adjustable roller spacing.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and enterprises with industry data support or platform statistical information to ensure the stability of equipment in plastic or rubber mixing scenarios.
  • In different scenarios such as rubber material pretreatment or recycled rubber processing, attention should be paid to the heating method of the open mill and the difference in roller speed. For high-temperature processes, it is recommended to choose electric heating models, while for low-temperature mixing, emphasis should be placed on the performance of the cooling system.
  • The roller material and transmission structure of the open mill directly affect durability. When purchasing, the difference in wear rate between cast iron rollers and alloy rollers in long-term use can be compared based on industry application case data provided by the supplier.
