This article explains the basics of dry powder classification and describes some of the most common classification methods available for bulk solids manufacturing applications.
Carbon Black is a material produced from the incomplete combustion of hydrocarbons and is an essential component in tires, rubber, plastics and liquids, enhancing these products by adding strength and durability. Most Carbon Black is produced in an atmosphere controlled furnace where fuel is introduced into a hot gas stream that produces sufficient heat to vaporize and pyrolyze the fuel into ultra-fine carbon particles. At this point the carbon black is an inconsistent mixture of fine particles and agglomerates referred to as grit. These grit particles are an unwanted byproduct, and can adversely affect the physical properties of the rubber and plastic products.
With the capability of on-site OEL testing services Hosokawa can offer an improved, single source supply of containment solutions to drug manufacturers seeking solutions for the safe handling of potentially harmful or high toxicity materials and for processors in other industries keen to meet the increasing obligations regarding personnel safety and product security.
When specialty fabric manufacturer Vlisco approached HML seeking a contained drum handling solution to provide a physical barrier between the operator and product to protect their workforce from contact with airborne, fabric dye particles, they were explicit in the challenges that needed to be met.
Drying specialist Hosokawa Micron B.V. offer competitive edge drying technologies and processing options for the production of complex pharmaceutical products.
In response to increasing market demand for high temperature powder processing Hosokawa Micron B.V. has developed a range of new technologies that address the requirement for processing temperatures up to 325°C.
Nauta Conical Screw Mixers are among the most popular homogenizers for blending powdered materials. Since Hosokawa invented the Nauta Mixer in 1946, over 15,000 blenders have been built, from 5 liter small batch mixers to large productionblenders with 120,000 liter capacity. The Nauta mixers are also available with many options and specialized configurations for vacuum drying, low and high shear mixing, and lyophilization.
Over the last 90 years, Hosokawa has conducted processing trials on thousands of food ingredients and installed hundreds of systems – everything from ultra-fine milling of sugar and blending large batches of dry ingredients, to vacuum drying and sterilization of delicate spices. Rob Voorhees, President of Hosokawa Micron Powder Systems, will be conducting a webinar focusing on processing seven common food materials on Wednesday, August 9th at 2:00 PM.
As products and technologies become more advanced in today’s markets, the need for materials with specific properties for special applications becomes more important. With the broad range of requirements, it is not practical to think that one type of milling technology will satisfy all needs. This article provides an overview of five product-specific milling technologies used in many industrial applications today. Read our article recently published in Processing Magazine (July 2017).
On Wednesday, October 4th, Hosokawa host the Powder Technology Symposium in Summit, NJ.
The development of particle processing technology is closely related to the new economy, which made use of more high-tech products towards the beginning of the 21st century. Applying ultrafine powders and nanoparticles to create new materials has caught the imaginations of researchers around the world. Although particle processing technology has gained significant progress in recent years, learning to use the processing technologies via particle characterization to achieve new product functionalities while meeting with the environmental and safety requirements is still challenging, but full of opportunities.
