The Pin Mill GSM 250 is a cryogenic grinding system of the highest quality. The milling plant is made of stainless steel. This also applies to the other system periphery such as the cooling screw conveyor, the filter, etc. The mill can be run with air, inert gas (nitrogen) or in cryogenic mode under liquid nitrogen.

Cryogenic grinding involves cooling a material below its embitterment temperature with a cryogenic fluid, typically liquid nitrogen or, in certain applications, carbon dioxide. After cooling, the material is fed into an impact mill where it is reduced in size primarily by brittle fracture.

Grinding at cryogenic temperatures creates ultra-fine particles in a very narrow distribution range.

Our sieving systems can be adjusted for a wide variety of application needs.

Cryogenic grinding, also known as freezer milling, freezer grinding, and cryomilling, is the act of cooling or chilling a material and then reducing it into a small particle size. For example, thermoplastics are difficult to grind to small particle sizes at ambient temperatures because they soften, adhere in lumpy masses and clog screens.

actual grinding. With our PolarFit cryogenic grinding system, you can process materials such as retread rubber, shoe soles/heels, weather stripping, urethane , chrome-plated ABS and vinyl-coated fabric. The cooling conveyor transfers the feed from the hopper to the grinding mill. Liquid nitrogen sprays onto the material as it moves along the

With cryogenic grinding we solve this problem. Thus, the pellets enter the mill and before grinding they are crystallized with liquid nitrogen at sub-zero temperatures to facilitate their breakdown and micronization. Also another advantage of cryogenic grinding is speed: An standard mill usually only reaches 5000rpm (depending on the model).

Hapman, Kalamazoo, MI 800. Laboratory Cryogenic Grinding System This system controls the flow of liquid nitrogen into the grinding chamber for customers performing cryogenic grinding. The engineered system includes a probe inside the grinding chamber that monitors the temperature, and at the same time, regulates the flow . Inquire Now

Cryogenic grinding is the act of cooling or chilling a material and then reducing it into a small particle size. Cryogenic grinding technology can efficiently grind most tough materials and can also facilitate cryogenic recycling of tough composite materials and multi component scrap. The term "cryogenics" originates from Greek word which means creation or production by means of cold.

Cryogenic grinding is a novel technology and with optimal processing conditions, its overall operating cost can be reduced. It helps to retain volatile compounds with increased recovery. The cryo-ground samples have uniform fine particle size, improved color and aroma along with more retention of volatile oil, total phenolics, total flavonoids ...
