Equipped with a variable-frequency drive (VFD) for programmable, stepless speed control.
The spacing between the rollers can be adjusted via a handwheel, preventing the grinding jar from shifting or drifting during operation.
The rollers are encased in wear-resistant polyurethane sleeves, which increase the coefficient of friction and prevent the grinding jar from slipping or becoming deformed.
Accommodates feed particle sizes of less than 3 mm (up to 10 mm for soil samples), with an output particle size ranging from 20 to 300 mesh (approx. 65–75 µm).
Features a single-jar configuration; lightweight and ideal for mixing small batches of samples in laboratory settings.

Introduction
The roller ball mill is a fundamental piece of equipment, critical to the processes of powder grinding and mixing. Its operating principle involves a main shaft connected to a motor via a pulley and bearing system. This shaft generates relative motion against the surface of the grinding jar—creating friction that drives the jar to rotate—while a secondary (passive) shaft supports the rotation. The rollers are encased in wear-resistant polyurethane sleeves, which increase the coefficient of friction and prevent the jars from slipping or becoming deformed. Our company offers a comprehensive range of roller ball mills, available in a wide variety of specifications and series. Our primary product lines include dry-grinding ball mills, wet-grinding ball mills, lined ball mills, grinding-and-sieving ball mills, laboratory-scale ball mills, and various customized models.
Applications
This equipment is widely used in industries such as cement, silicate products, advanced building materials, refractories, chemical materials research, bio-fertilizers, non-ferrous metal ore processing, and the production of glass and ceramics. It is designed for the dry or wet mixing of various ores and other grindable materials. Furthermore, it is suitable for grinding and mixing processes in sectors including electronics, ceramics, coatings, glass powder, fluorescent materials, non-metallic minerals, pharmaceuticals, electronic materials, magnetic components, battery manufacturing, biological cultivation, food packaging, and battery materials.
Mixing
The equipment operates via two rotating rollers, which induce a consistent, patterned motion in the grinding media (balls). This ensures uniform internal movement, preventing issues such as material sticking to the walls or sedimentation. Its primary strength lies not in ultra-fine grinding, but in the mixing of dry powders, slurries, and nanomaterials. Compared to other types of ball mills, the roller-type ball mill offers superior mixing performance. Experimental data analysis shows a narrower particle size distribution curve with a higher peak, which ensures greater stability for the material in subsequent processing stages.
