Description

Vertical Semi-Circular Planetary Ball Mill

Product Introduction

A planetary ball mill is a high-efficiency and precise laboratory-grade powder preparation device, mainly used for material crushing, mixing, dispersion, and nanomaterial preparation. Its core structure consists of a planetary disk, ball milling jars (semi-circular or circular), grinding balls, a drive system, and safety devices. Through the composite motion of revolution and rotation of the planetary wheels, combined with high-energy impact and friction, the equipment achieves efficient grinding of materials. The semi-circular ball milling jar design further optimizes space utilization and grinding efficiency, making it suitable for small-batch and high-precision experimental requirements.

Operating Principle of Planetary Ball Mill

The main disk of the planetary ball mill is equipped with four ball milling jars. When the motor drives the main disk to rotate, the ball milling jars revolve around the main disk shaft and simultaneously rotate under the drive of the main disk’s planetary mechanism, performing planetary motion. The grinding balls inside the jars rub and collide with each other during high-speed planetary motion, enabling efficient grinding and sample mixing.

The vertical semi-circular planetary ball mill is a device used for mixing, fine grinding, small-sample preparation, new product development, and small-batch production of high-tech materials. Our planetary ball mill features a compact size, complete functions, high efficiency, and low noise. It is an ideal powder equipment for research institutes, universities, and enterprise laboratories to obtain research samples (four samples can be obtained simultaneously in each experiment). Equipped with vacuum ball milling jars, it can grind samples in a vacuum state.

Application Scope

Working Principle

Planetary Motion Mechanism: The turntable drives the ball milling jars to revolve around the main shaft, while the jars rotate at high speed, forming a composite centrifugal force field.
Grinding Effect: Grinding balls inside the jar collide with materials at high speed under centrifugal force, generating shearing, impact, and friction forces to achieve crushing and mixing.
Parameter Control: Precisely control the finished product particle size by adjusting the rotation speed (e.g., 200-800 rpm), grinding time, and ball-to-material ratio.

Selection Guide

Sample Properties: Wear-resistant jars (e.g., tungsten carbide) are required for hard materials; the low-temperature grinding mode is optional for brittle or heat-sensitive materials.
Processing Capacity: Choose a single-jar or four-jar configuration according to experimental needs, with the loading capacity not exceeding 2/3 of the jar volume.
Grinding Objective: Nanoscale grinding requires a high rotation speed (≥500 rpm) and small-sized grinding balls (e.g., zirconia balls).
Equipment Parameters: Focus on motor power (e.g., 0.75-2.2 kW), maximum centrifugal acceleration, and timing function.
Safety & Maintenance: Prioritize models with automatic shutdown, fault alarm, and easy disassembly design to reduce maintenance costs.
