Product DescriptionProduct DescriptionProduct Description of S61 Series Rotary Drum Heating FurnaceThe S61 Series Rotary Drum Heating Furnace is a high-efficiency industrial heating system designed for continuous heating, drying, calcining, and preheating processes. It is widely used in core drying in foundries, refractory calcination, catalyst regeneration, chemical raw material drying, and pre-treatment of lithium battery cathode/anode materials. Featuring a horizontal rotating drum + external heating + intelligent temperature control, the furnace rotates slowly to tumble materials evenly, combined with hot air circulation or electric/gas heating, achieving efficient heat transfer, uniform heating, and dead-zone-free drying—ensuring process consistency and product quality stability.The furnace features a modular design with optional heating methods: electric, natural gas, LPG, or biomass fuel. Temperature range: ambient to 1200°C, capacity: 500 kg/h to 10 tons/h. Customizable based on material properties, production capacity, and process curves to meet diverse industrial needs.Working PrincipleThe S61 Series achieves continuous, uniform heating through mechanical rotation + convective/radiative heat transfer:Feeding & DistributionMaterials are continuously fed into the front end of the drum via screw feeder, belt conveyor, or bucket elevator, ensuring uniform and stable feeding.Rotating HeatingThe drum is driven by a frequency-controlled motor + gearbox at 2–6 rpm, slowly rotating. Materials tumble and fall inside, increasing contact area with hot air and enhancing heat transfer.Hot Air Circulation HeatingElectric Type: Electric heating elements heat air, which is forced through the drum by a high-temperature fan. Hot air enters from the rear, counter-current to material flow, ensuring full heat exchange before exhaust.Gas Type: High-temperature flue gas from a burner heats clean air via a tubular heat exchanger, then enters the drum—avoiding direct contact and contamination.Discharge & Cooling (Optional)Heated material discharges from the rear. Optional cooling drum or air-cooling system allows hot or ambient-temperature discharge for downstream packaging or processing.Exhaust Gas TreatmentExhaust gas is treated via cyclone + bag filter + optional activated carbon adsorption before emission—compliant with environmental standards (GB 16297-1996).Key FeaturesUniform Temperature, Precise ControlMulti-zone external heating with multi-point thermocouples + PID control ensures internal temperature deviation ≤±15°C—consistent material heating.Energy-Efficient, Low Operating CostDouble-layer insulation (ceramic fiber + refractory brick) keeps surface temperature ≤50°C, minimizing heat loss. Gas models ≥85% thermal efficiency; electric model be equipped with waste heat recovery.Robust Structure, Stable OperationDrum made of Q345R boiler steel or heat-resistant stainless steel (310S). Precision-machined rollers and riding rings ensure smooth, low-vibration operation—service life ≥10 years.Intelligent Control SystemPLC + 10" HMI touchscreen supports multi-stage heating profiles, data logging, fault alarms, remote monitoring (optional), and integration with MES.Safe & Reliable, Easy MaintenanceEquipped with over-temperature protection, gas leak alarm (gas models), emergency stop, explosion relief port; wide access doors and quick-change components simplify maintenance.Eco-Friendly, Green ProductionExhaust treatment effectively removes dust and harmful gases—emission ≤30mg/m3, compliant with national standards.Main Technical SpecificationsParameterSpecificationModel SeriesS61-800 / S61-1200 / S61-1500 / S61-2000 Based on drum diameterDrum DiameterΦ800 / Φ1200 / Φ1500 / Φ2000 mmDrum LengthCustomizableInclination AngleAdjustableSpeedVFD adjustableTemperature RangeAmbient to 1200°CHeating MethodElectric / Natural Gas / LPG / BiomassCapacityDepending on materialControl SystemPLC + HMI + Optional Remote MonitoringInsulationCeramic fiber + refractory (300mm)Surface TemperatureAt 25°C ambientWeight8,000 ~ 25,000 kgDimensionsCustomized by modelTypical ApplicationsContinuous drying and curing of resin sand cores and shell cores in foundriesCalcining of high-alumina bricks and magnesia-carbon brick blanksRegeneration of catalysts, molecular sieves, and desiccants in chemical industryPreheating and activation of cathode materials (e.g., NCM, LFP) for lithium batteriesDrying and preheating of agricultural by-products (sand, ore powder, aggregates)Pre-treatment for pyrolysis of organic waste in solid waste recyclingCompany ProfileQingdao Dingli Machinery Co., Ltd.Qingdao Dingli Machinery Co., Ltd. is a company specializing in the production of casting machinery equipment.
