The new 3 in 1 Drymeister-H is the latest multiprocessing unit from Hosokawa Micron and offers energy efficient and speedy grinding, classifying and drying operations in one compact unit.
The Drymeister-H combines intensive dispersion with high performance classification to deliver stable product quality, particle size and moisture content and is applicable for drying slurries, solutions, wet powder and pasty cake, giving speedy and reliable results.
Wet material is fed down to the grinding chamber to be dispersed and dried using hot gas. The ground and dried powder is carried to the classifier. Fine particles go through the classifier wheel and are transported to a bag filter. Coarse particles fall down to the grinding chamber to be further milled and dried. Particle size of the product is determined by the rotor speed of the classifier. Moisture content of the product is determined by the outlet gas temperature of the dryer and residence time in the dryer which is influenced by the classifier speed.
When compared to traditional spray or rotary dryers, the Drymeister offers processors energy savings of 50-70%. A fluidised bed of product in the drying chamber in conjunction with a heated drying track ensures a low level of adhesion of undried product. The combination of the fluid bed with the grinding/dispersion rotor contributes to the Drymeister-H’s very compact size compared to conventional flash driers or spray dryers.
With options for ceramic faced wear parts and a specially designed screw feeder for cakey material the Drymeister-H has applications across a range of industries with typical uses in the processing of retardants, lithium cobaltite, minerals, foods, detergents, pesticides, surfactants and pigments.
