Planetary ball mill products of different models and specifications from Hunan Powder Research Institute
Heavy-duty horizontal ball mill
Model: WXQM
The heavy-duty horizontal planetary ball mill adopts a double-disc, end-support bracket structure, which effectively improves the equipment's stability and load-bearing capacity, overcoming the limitation of light-duty horizontal planetary ball mills being restricted to light-load applications. The heavy-duty horizontal planetary ball mill is mainly suitable for pilot-scale or small-batch grinding production.
Planetary ball mill (semi-circular model) XQM
Model: XQM-0.4~16A
A planetary ball mill is a high-efficiency, precision laboratory-grade powder preparation device, primarily used for the crushing, mixing, dispersion, and preparation of nanomaterials. Its core structure includes planetary discs, a grinding jar (semi-circular or circular), grinding balls, a drive system, and safety devices. The equipment achieves efficient material grinding through the combined motion of the planetary gears' revolution and rotation, along with high-energy impact and friction. The semi-circular grinding jar design further optimizes space utilization and grinding efficiency, making it suitable for small-batch, high-precision experimental needs.
Low-temperature planetary ball mill
Model: XMQ
A low-temperature planetary ball mill is a combination of a planetary ball mill and a refrigeration unit. During high-speed grinding, most materials experience temperature increases due to friction or exothermic reactions, potentially altering their physicochemical properties and negatively impacting the grinding process. Low-temperature planetary ball mills are primarily used in grinding processes requiring strict temperature control.
Vertical square planetary ball mill
Model: XQM-2~100
Vertical square planetary ball mills are powder processing 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, making them 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 grinding jar, samples can be ground under vacuum conditions.
360° Rotating All-Around Experimental Planetary Ball Mill
Model: QXQM-2~40
The 360-degree rotating planetary ball mill is based on the vertical planetary ball mill, with the addition of a planetary disk flipping function. While the planetary disk and the grinding jar are performing planetary motion, they can also perform a 360° tipping-style flipping within a three-dimensional space, realizing multi-dimensional and multi-directional movement of the grinding jar.
Horizontal light ball mill
Model: WXQM
The lightweight horizontal planetary ball mill consists of four horizontally mounted grinding jars symmetrically mounted on a vertical planetary disk.
All-round production planetary ball mill
Model: QXQM
The all-round production planetary ball mill has a large production capacity, short production cycle and high production efficiency. While the planetary structure rotates on its own axis and around the sun, the whole machine rotates 360 degrees, thereby achieving multi-dimensional and multi-directional grinding, which can solve the problems of some materials easily settling and caking.
Microcomputer planetary ball mill
Model: XMQ
The microcomputer planetary ball mill is based on the conventional planetary ball mill and equipped with a touch screen operation control system, which further improves the equipment level and control performance. The microcomputer planetary ball mill is mainly designed to meet the needs of users who have higher requirements for equipment quality and control performance.
Soil grinder and screen
Model: XQM
For soil heavy metal analysis, four agate grinding jars are required. The pressure of the sealed agate grinding jars is set via a scale. While revolving around a rotating disk axis, the jars also rotate in the opposite direction around their own axes. The samples inside collide and rub against each other during high-speed motion, achieving the purpose of crushing, grinding, mixing, and dispersing the samples. Dry grinding, wet grinding, and vacuum grinding are all possible. Two or four grinding jars can operate simultaneously.
Ultrasonic planetary ball mill
Ultrasonic planetary ball mills are products developed based on the grinding principle of traditional planetary mechanisms. The equipment is mainly used for mixing and fine grinding of materials that require high particle size and that would cause settling, clumping, sticking to the walls, and agglomeration when using traditional ball mills.
Double planetary ball mill
Model: SXQM
The dual planetary structure enables the large planetary disk to drive the small planetary disk, and the revolution radius and the rotation speed of the grinding jar are amplified compared with ordinary planetary ball mills of the same specifications. The centrifugal force on the grinding balls is multiplied, and the collision, shearing and friction between the grinding balls are significantly increased, improving the grinding effect and grinding efficiency. Some materials can be ground to the nanoscale.
Vertical production planetary ball mill
Model: XQM
Vertical production-type planetary ball mills are large-scale planetary ball mills designed and manufactured based on the principle of small planetary ball mills. Production-type planetary ball mills are mainly suitable for users' batch grinding production.
Continuous planetary ball mill
Model: LXYM
This model is a newly invented high-efficiency planetary powder processing equipment, and it is the preferred equipment for scientific research, teaching, experimentation and production of nanoscale materials and ultrafine powders.
