Brief introduction of vertical dryer: Vertical drying equipment, also called vertical dryer, is designed for the dehydration of briquette and pellet. It has reasonable design, high thermal efficiency, good drying effect and adjustable air volume. This type of vertical dryer is made of steel structure; Inner lining adopts heat preservation materials to keep warm; Multilayer high temperature castings are adopted in the roaster; There are vibration system, interception system, temperature control system and intelligent control system installed on some relevant parts of the machine; Vapor and smoke are collected with the application of a draught fan and a cyclone dust collector. Techinique information: Inner lining adopes heat preservation materials to keep warm and multilayer high temperature casting are also adopted in the roaster. Moreover, there are vibration system, interception system, temperature control system and intelligent control system installed on some relevant parts of the machine. Vapor and smoke re collected with the application of a draught fan and a cyclone dust collector.
