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.
The molded balls which contain much moisture are transmitted to the top by conveyor, and then they are evenly distributed on the top cross-section by distribution device. Briquettes fall down slowly by gravity, exchange heat with strong wind at the same time.
The moisture which is evaporated from briquette is taken away randomly by the strong wind. The briquettes achieve intensive drying after two hours evaporation process.
Material is pressed into shapes by briquette press machine; the moisture is usually at 12%-14%. After dried, the moisture can reduce to 2-4%, also can satisfy the request of hardness, storage and transportation.
Economic characteristics: the amount of investment reduced by 1/2; area is 1/5-1/3; energy consumption and operating costs significantly reduced.
Advantages: This product matching process is good, easily in connection with other equipments and automation in production line. Equipments are easy for operation and simple for maintenance. Drying furnace body has no mechanical moving parts, no maintenance routine. It is characterized by continuous operation, high efficiency, large output.
