Product Overview

RED single drum rotary dryer (also named single cylinder rotary dryer / single-pass rotary dryer) is a widely used continuous drying equipment for bulk granular and powdery materials. It adopts an inclined rotating steel drum with internal lifting flights to scatter materials evenly, enabling full contact between wet raw materials and hot airflow for moisture evaporation. Built for heavy-duty industrial production, RED single drum rotary dryer balances large throughput, low maintenance and stable running performance. It is a preferred drying solution for dry mortar plants, mineral processing lines, biomass recycling, sand production and building material factories.

Supporting System

A complete RED single drum rotary dryer system includes feeding device, rotary drum, hot air furnace, dust collector, induced draft fan, discharging conveyor and control cabinet. We can supply standalone dryer or full turnkey drying line according to your site layout and production requirements. 7ec791a2266777431ec9acd788d6422fd5b2035244e5be684fe6a80ca1c71297

FAQ

Q1:What materials can a single drum rotary dryer process?

It is suitable for non-viscous or slightly sticky granular and powder materials, such as sand, biomass, clay, mineral powder, fly ash and sludge. For highly sticky materials, we will optimize internal flight structure.

Q2:Can I customize the heat source?

Yes. RED supports multiple heat sources including coal-fired hot blast stove, biomass burner, gas burner and electric heating system based on local fuel cost and environmental rules.

Q3:What is the delivery time and warranty?

Standard single drum rotary dryer normally takes 20–35 working days. Core components enjoy 12 months warranty.

Q4:Do you support on-site installation guidance overseas?

We provide English installation manual, video guidance and overseas engineer service on request.
