Planetary ball mill (semi-circular model)

Product Introduction

Planetary ball mill is an efficient and precise laboratory-grade powder preparation equipment, mainly used for crushing, mixing, dispersing materials and preparing nanomaterials. Its core structure includes planetary disk, ball mill tank (semi-circular or circular), grinding ball, drive system and safety device. The equipment achieves efficient grinding of materials through the compound motion of the planetary wheel's revolution and rotation, combined with high-energy impact and friction. The semicircular ball mill tank design further optimizes space utilization and grinding efficiency, and is suitable for small batch and high-precision experimental requirements.  

Vertical semicircular planetary ball mill is a device for mixing, fine grinding, sample preparation, new product development and small batch production of high-tech materials. Our planetary ball mill has small size, full functions, high efficiency and low noise. It is a powder equipment for scientific research institutions, universities and corporate laboratories to obtain research samples (four samples can be obtained simultaneously in each experiment). Equipped with a vacuum ball mill tank, the samples can be ground in a vacuum state.

Technical parameters

Basic configuration parameter table

Performance parameter table

• Sample properties : Hard materials require a wear-resistant tank (such as tungsten carbide), and brittle or heat-sensitive materials require a low-temperature grinding mode.

• Throughput : Choose a single tank or four-tank configuration according to experimental requirements, and the filling volume should not exceed 2/3 of the tank volume.

• grinding target : Nanoscale grinding requires high rotation speed (≥500 rpm) and small particle size grinding balls (such as zirconia balls).

• Equipment parameters : Pay attention to the motor power (such as 0.75-2.2 kW), maximum centrifugal acceleration and timing function.

• Security and Maintenance : Give priority to models with automatic shutdown, fault alarm and easy-to-disassemble design to reduce maintenance costs.

Working Principle

• planetary motion mechanism : The turntable drives the ball mill tank to revolve around the main axis, and at the same time, the tank itself rotates at high speed, forming a composite centrifugal force field.

• grinding action : The grinding balls in the tank collide with the materials at high speed under the action of centrifugal force, generating shear, impact and friction to achieve crushing and mixing.

• Parameter control : Precisely control the particle size of the finished product by adjusting the rotation speed (such as 200-800 rpm), grinding time and ball-to-material ratio.

Product Features

• Efficiency : Planetary motion mode (revolution + rotation) provides high energy density, and the grinding efficiency is significantly improved compared to traditional equipment.

• Uniformity : The three-dimensional movement trajectory ensures that the materials are fully mixed and the particle size distribution is uniform (the minimum can reach 0.1 micron).

• Versatility : Supports dry/wet grinding, suitable for ball mill tanks made of different materials (such as stainless steel, ceramics, polyurethane).

• Safe and reliable : Equipped with safety switch, overload protection and low-noise design, complying with laboratory safety standards.

• Intelligent control : Frequency control, timing forward and reverse, LED display and programmed operation to improve the repeatability of experiments.
