Planetary Ball Mills For Mixing, Fine Grinding, Small-sample Preparation, Nanomaterial Dispersion

Planetary ball mills are essential equipment for mixing, fine grinding, small-sample preparation, nanomaterial dispersion, new product development, and small-batch production of high-tech materials. These products are compact, multifunctional, highly efficient, and low-noise, making them ideal for research institutions, universities, and corporate laboratories to obtain microparticle research samples (up to four samples per experiment). When equipped with a vacuum grinding jar, samples can be ground under vacuum. They are widely used in geology, mining, metallurgy, electronics, building materials, ceramics, chemical industry, light industry, pharmaceuticals, cosmetics, and environmental protection sectors. The rotation speed, forward and reverse rotation alternation time, and total grinding time can be set according to process requirements.

Guangzhou Zoli Technology Co., Ltd. consists of four grinding jars mounted on a single rotating disc. As the disc rotates, the grinding jars revolve around the disc's axis while simultaneously rotating on their own axes, performing planetary motion. The grinding balls within the jars collide with each other during high-speed motion, grinding and mixing the sample. This product can grind and mix products of different particle sizes and materials using both dry and wet methods, achieving a minimum particle size of 0.1 micrometers (i.e., 1.0 × 10⁻⁴ mm⁾.

The microcomputer-controlled planetary ball mill is a high-tech product recently developed by Guangzhou Zoli, featuring user-programmable computer control. Users can input parameters such as rotation speed, forward and reverse rotation, and grinding time according to their grinding needs. It boasts a user-friendly human-machine interface and touchscreen control. The microcomputer-controlled planetary ball mill is an essential device for mixing, fine grinding, small-sample preparation, new product development, and small-batch production of high-tech materials. Zoli's planetary ball mill is compact, multifunctional, highly efficient, and low-noise, making it an ideal device for research institutions, universities, and enterprise laboratories to obtain research samples (up to four samples can be obtained simultaneously in each experiment). Equipped with a vacuum grinding jar, it can grind samples under vacuum conditions.

• Gear transmission overcomes the shortcomings of traditional belt transmission, such as easy slippage and unstable speed.
• This maintains the stability of gear transmission while overcoming the shortcomings of traditional belt transmission, such as slippage and unstable speed.
• The ball mill jar uses planetary motion, resulting in high ball milling efficiency and fine particle size.
• Variable frequency control allows the selection of the ideal speed based on test results;
• The frequency converter has undervoltage and overcurrent protection, which can provide some necessary protection for the motor;
• The integrated unit features timed shutdown, automatic timed forward and reverse rotation functions, and allows users to freely select unidirectional, alternating, continuous, timed, and untimed operation modes to improve grinding efficiency.
• A single experiment can simultaneously yield four samples of different sizes and materials;
• Low center of gravity, stable performance, compact structure, easy operation, safe and reliable, low noise, no pollution, and low loss;
• The equipment is equipped with a safety switch to prevent it from starting with the safety cover open, thus avoiding safety accidents.
• of a horizontal planetary ball mill is a horizontal device, it does not have a fixed bottom surface when rotating, which effectively solves the problem of some materials settling to the bottom.

1. Model Description: XQM- (Total Volume of 4 Jars)
   Example: XQM-4: A planetary ball mill with a total volume of 4L, capable of holding four 1L ball mill jars; therefore, the model of equipment should be selected based on the amount of material to be ground in one operation.

2. Selection of grinding jars:

   The main materials for grinding jars include: stainless steel, agate, corundum, tungsten carbide, nylon, zirconium oxide, polytetrafluoroethylene, and polyurethane lining, etc. The selection principle is that the material of the grinding jar should not contaminate the material to be ground and should not affect its appearance.

   When grinding materials that are prone to oxidation and must be isolated from air, a vacuum ball mill jar can be used;

3. Grinding ball selection:

   Grinding ball materials mainly include: chrome steel, stainless steel, agate, alumina, zirconium oxide, etc. The selection principle is that the grinding ball material should not contaminate the material being ground or affect its appearance; the density and hardness of the grinding ball material must be greater than that of the material being ground; the main specifications for grinding balls are: Φ5 , Φ8, Φ10, Φ20 .

4. Grinding ball ratio:

   The efficiency of ball milling depends on the ball selection (large, small, many, few), the properties of the sample, particle size, weight, rotation speed, and operating mode. For optimal results, large and small balls should typically be used in combination. Large balls are used for weighting, crushing the sample, and dispersing the smaller balls, while small balls are used for mixing and grinding the sample.
