Due to the fact that it is not possible to grind rubber granules any finer in an economical way it becomes necessary to separate a finer product fraction from the cryogenic process downstream For such applications the Alpine Stratoplex ASP II turned out to be the ideal machine with regard to yield efficiency and investment costs
Cryogenic grinding We grind a number of different plastics for a great variety of applications with our cryogenic mills Whatever the end use of your polymer we process your powder to your exact specifications with our modern production systems Hosokawa Micron Powders GmbH Welserstr 9 51149 Köln Germany Phone 49 2203 308 0 info
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 Depending on the micron size the pellets turns into powder as the blade mill turns Together with a sieve the product is
Cryogenic Pulverizer using liquid nitrogen to lower the input material temperature to material embrittlement condition firstly then go to the grinding chamber the input materials were throughly pulverized through blade wheel S high speed rotating and the comprehensive force like mutual repeatedly impact crash shear and friction between the materials and blades fluted disc
Also another advantage of cryogenic grinding is speed An standard mill usually only reaches 5000rpm depending on the model A normal mill that works at more than 5000rpm needs cooling by water air special bearings etc Depending on the micron size the pellets turns into powder as the blade mill turns Together with a sieve the
Experience precision in cryogenic grinding with Shri Krishna Pulverisers specialized machinery This low temperature grinding process using liquid nitrogen produces fine uniform particle sizes and is widely used in the food pharmaceutical and chemical industries Our machinery including hammer mills and pin mills is designed for various scales of production Explore our cryogenic
·Hosokawa Alpine is a member of the Hosokawa Micron Group a high performance manufacturer of systems for powder and particle processing The graph plots a direct comparison between the grinding results of a cryogenic grinding process and those of a grinding process at ambient temperature The d 50 value was improved from approx 480 µm
Grinding spices is one of most challenging comminution tasks of all Not only does the structure of spices vary widely but also the grindability Some spices for example turmeric can differ dependent on how they are grown and when they are harvested Hosokawa delivers complete systems for any spice and dried vegetable for every fineness requirement and final application
There is an economic caveat to cryogenic grinding The more liquid nitrogen is used the cooler the temperature becomes and the more pulverisable and fine particles can usually be obtained The problem is that when you want smaller particles the amount of liquid nitrogen used becomes very high and the throughput is drastically reduced
