Grinding & Classifying
In addition to toll screening, Elcan also offers customers the opportunity to toll grind and classify with us as well on our line of STM Micron equipment. All of the equipment in our facility is available for both testing and toll processing.
Elcan Industries has a SDF Series Dynamic Air Classifier installed in our plant. The ultra-high efficiency dynamic air classifier is equipped with a two-stage, dual air intake and a centrifugal type rotor to accurately classify the entrained powder. The precision engineering of the SDF Series prevents unwanted particle bypass to ensure that only the desired fraction is collected. The desired fineness is easily adjustable and assembly, maintenance and cleaning operations are extremely simple. These features allow the classifier to make precise separations at very small micron sizes.
We also have installed a sieve mill, which is similar to a hammer mill except it uses a screen to determine particle size. Within the sieve mill, the grinding is achieved by the material impacting the grinding tools mounted to the grinding disc. The grinding disc rotates around the grinding track, which includes the sieve itself. The sieve acts like a classifier as it determines the particle size according to its hole diameter. Final particle size is determined by a number of different factors that are adjusted based on each specific product’s sizing requirements. The machine has a simple design with a wide range of accessories and this along with numerous grinding disc designs and different sieve sizes make it suitable for virtually every purpose.
We are currently in the process of installing an MJS Fluidized Bed Jet Mill, which will be operational by the end of 2017. The MJS Jet Mill consists of a grinding unit which uses high pressure gas and a variable rotary classifier for precise selection of particle size. The high impact speed and accelerated air flow from the nozzles produce a high collision speed and allow for very efficient grinding. These advanced features enable the mill to pulverize extremely hard, abrasive products. Inside the unit, a turbine classifier is used for ultra fine powders, which results in a very precise selection and a tight curve of particle size distribution. The design of the machine allows for easy cleaning and the quality of the construction of the machinery eliminates the possibility of iron contamination as a result of wear and tear. The equipment features a completely automatic operation, which eliminates the need for constant supervision while in use.
