Vertical semi-circular planetary ball mills are devices used for mixing, fine grinding, small-sample preparation, new product development, and small-batch production of high-tech materials. Our planetary ball mills are small in size, multifunctional, highly efficient, and low in noise. They are ideal for research institutions, universities, and enterprise laboratories to obtain research samples (up to four samples can be obtained simultaneously in each experiment). When equipped with a vacuum ball mill jar, samples can be ground under vacuum conditions.

Vertical semi-circular planetary ball millsare widely used in geology, mining, metallurgy, electronics, building materials, ceramics, chemical industry, light industry, medicine, environmental protection and other sectors. They are suitable for the production of electronic ceramics, structural ceramics, magnetic materials, lithium cobalt oxide, lithium manganese oxide, catalysts, phosphors, long afterglow luminescent powders, rare earth polishing powders, electronic glass powders, fuel cells, zinc oxide varistors, piezoelectric ceramics, nanomaterials, disc ceramic capacitors, MLCCs, thermistors (PTC, NTC), ZnO varistors, dielectric ceramics, alumina ceramics, zirconium oxide ceramics, phosphors, zinc oxide powder, cobalt oxide powder, Ni-Zn ferrite, Mn-Zn ferrite and other products.

Technical parameters

Working principle

Planetary motion mechanism : The turntable drives the mill jar to revolve around the main shaft, while the jar itself rotates at high speed, forming a composite centrifugal force field.

Grinding action : The grinding balls inside the tank collide with the material at high speed under the action of centrifugal force, generating shearing, impact and friction forces to achieve crushing and mixing.

Parameter control : The particle size of the finished product can be precisely controlled by adjusting the rotation speed (e.g., 200-800 rpm), grinding time, and ball-to-material ratio.

Selection Guide

Sample properties : For hard materials, wear-resistant canisters (such as tungsten carbide) should be selected; for brittle or heat-sensitive materials, low-temperature grinding mode can be selected.

Processing capacity : Select a single tank or four-tank configuration according to experimental requirements, with the filling amount not exceeding 2/3 of the tank volume.

Grinding target : Nanoscale grinding requires high rotation speed (≥500 rpm) and small-diameter grinding balls (such as zirconia balls).

Equipment parameters : Pay attention to motor power (e.g., 0.75-2.2 kW), maximum centrifugal acceleration, and timing function.

Safety and Maintenance : Prioritize models with automatic shutdown, fault alarms, and easy disassembly design to reduce maintenance costs.
