A chocolate ball mill refiner is one of the most commonly used grinding equipment to grind and refine coarse raw materials such as cocoa, sugar and other ingredients of a chocolate paste. As it will be easly understood from its name, a chocolate ball mill refiner contains lots of balls which are commonly made of steel.
When a certain degree of wear of roller and ring is affected, it is recommended to adjust the length of the spring to maintain the constant pressure between the roller and the ring. As a result, the stable output and fineness are ensured.
And its rolling pressure ration is 1.2 times higher than that of the raymond grinder under the same power condition and the production output is raised to substantial degree.
The Ball Mill is used to grind many kinds of mine and other materials, or to select the mine.2 It is widely used in building material, chemical industry, etc. There are two ways of grinding: the dry way and the wet way. It can be divided into tabular type and flowing type according to different expelling mine.
Our ball mills have been used to grind glass, powder food products, creat custom varnishes, make ceramic glaze, powder various chemicals, and make black powder.
Cryogenic Mill with Closed Liquid Nitrogen (LN2) Auto-fill: LPM-01
Overview:
The LPM-01 cryogenic mill with closed liquid nitrogen (LN2) auto-fill system is carefully developed by RUISHENBAO® analytical (shanghai) Co., Ltd, which pulverize and mix some soft, temperature-sensitive or high fat content of samples such as candy, chocolate, Soybeans, peanuts and other food samples for sample preparation in laboratory. The grinding jar is continually cooled with liquid nitrogen from the integrated LN2 cooling system before and during the grinding process. Thus the sample is embrittled and volatile components are preserved. The liquid nitrogen circulates through the system and is continually replenished from an auto-fill system in the exact amount which is required to keep the low temperature of user that evenly reach -196 °C depending on the continuously filling time and amount of LN2. Powerful impact vibratory disc mill results in a perfect grinding efficiency. The auto-fill system avoids direct contact with LN2 and makes cryogenic grinding very safe. Its versatility (cryogenic, wet and dry grinding at room temperature) makes the LPM-01 the ideal mill for quantities up to 100-500 mL (depend on feed material). Its typical area of application includes food analysis, plastic product analysis, mineral analysis, medical aid analysis, drug performance testing, and identification of textile components and so on.

� Noise-insulated grinding chamber and especially safe hood locking;
Fields of application:
Agriculture, chemistry/plastics, construction materials, engineering/electronics, environment/recycling, food, geology/metallurgy, glass/ceramics, medicine/pharmaceuticals.
Typical samples include: animal feed, bones, chemical products, food, hair, oil seeds, paper, plant materials, plastics, sewage sludge, soils, tablets, and textiles, waste samples, wood, wool and so on.
Overviewï¼?
The PM-01XL is developed by RUISHENBAO® analytical (shanghai) Co., Ltd, which is a new-type high capacity dry-mill and specifically designed to offer many practical advantages in all areas in which hard, brittle and fibrous material must be ground extremely quick down to fineness in modern laboratory. It can grind up to 100-500mL of dry samples per grinding within short time (max. equivalent of 500g, depend on feed material). In this mill, the grinding is performed by horizontal circular oscillations of the grinding set on a vibrating plate. The grinding set consisting of a disc comminute the grinding sample with extremely high pressure, impact forces and friction. The instrument runs steadily and smoothly at maximum speed thanks to the stabilized plane designed. Due to the high end fineness and speed the PM-01XL is the perfect mill when it comes to preparing high-capacity and fineness samples for laboratory requirement. The circular vibrations are produced by a frequency controlled and touch-screen programmable controls for grinding cycles. The PM-01XL is suitable for the extremely quick, loss-free, high-capacity and reproducible grinding for modern laboratory.

Model PM-01XL
Feed material Hard, medium-hard, brittle fibrous
Size reduction principle Impact, friction, pressure
Overview:
The PrepM-01 vibratory disc mill series offer many practical advantages in all areas in which hard, brittle and fibrous material must be ground extremely quick down to fineness for spectral or X-ray fluorescence analysis. In the vibratory disc mill, the grinding is performed by horizontal circular oscillations of the grinding set on a vibrating plate. The grinding set consisting of ring and puck comminute the grinding sample with extremely high pressure, impact forces and friction. The instrument runs steadily and smoothly, even with heavy grinding sets, at maximum speed thanks to the stabilized plane designed. It has proven to be ideal for use in the building materials sector (cement), in geology, mineralogy, metallurgy and in power plants. Due to the high end fineness and speed PrepM-01 vibratory disc mill is the perfect mill when it comes to preparing samples for spectral analysis. The circular vibrations are produced by a frequency controlled or constant speed motor according to different models. It ensures that the motor output is precisely matched to the grinding material and grinding set - which optimises the energy consumption.
