Horizontal Rotating Dryer 15TPH-20TPH Triple Pass Rotary Drum Dryer

The 15-20 TPH dry mortar dryer is an upgraded high-capacity three-pass rotary drying equipment specially designed for large-scale dry mixed mortar production lines. It is professionally applied to dehumidify and dry granular raw materials such as river sand, quartz sand, manufactured sand and fine aggregate for commercial dry mortar. Adopting optimized three-layer nested rotary drum structure and circulating hot air exchange technology, the equipment achieves continuous feeding, uniform flipping, high-efficiency heat drying and automatic discharging. It stably reduces raw material moisture from 13%-18% to 0.5%-1%, completely eliminating the problems of mortar caking, packaging jamming and unstable product quality caused by high water content of raw sand. With a rated stable output of 15-20 tons per hour, higher thermal efficiency and stronger continuous operation capability, it perfectly matches high-speed large-capacity dry mortar mixing and full-automatic packaging lines. It is the core front-end drying equipment for standardized, high-yield and intelligent large dry mortar production bases.

It perfectly adapts to 24-hour high-load continuous production of large dry mortar lines, completely solving the output bottleneck of conventional 10-15TPH dryers and meeting mass order production demands.
• Industry-Leading Thermal Efficiency & Energy Saving: Optimized internal lifting plate arrangement and closed hot air circulation + waste heat recovery system, the thermal efficiency reaches above 85%. Compared with traditional single-cylinder dryers, it reduces comprehensive energy consumption by 40%-60%, featuring lower operating cost and higher production benefits for long-term operation.
• High-Precision Constant Moisture Control: Equipped with upgraded intelligent PLC temperature control and frequency conversion speed regulation system. The drum speed, feeding volume and hot air temperature are dynamically adjusted in real time according to raw material humidity and particle difference. The finished material moisture is stably controlled within 0.5%-1%, ensuring uniform drying effect and consistent mortar batch quality.
• Heavy-Duty Wear-Resistant & Durable Structure: The inner drying drum adopts thickened high-manganese wear-resistant alloy steel plate, with enhanced anti-abrasion and high-temperature resistance. The whole machine undergoes high-temperature anti-corrosion spraying and reinforced welding process, adapting to long-term high-intensity sand abrasion and high-temperature working conditions, with longer service life and lower failure rate.
• Multi Heat Source Compatibility & Environmental Protection: Flexible multi-heat source adaptation, compatible with natural gas, diesel, biomass, coal and electric heating. Reserved standard dust removal interface, matched with pulse dust removal equipment to effectively control dust overflow during drying process, fully meeting industrial environmental protection emission standards for building material workshops.
• Intelligent Unmanned Operation & Wide Adaptability: Integrated touch screen automatic control realizes one-key start-stop, automatic constant temperature operation and real-time fault self-diagnosis. It supports stable drying of various mortar raw materials with particle size below 20mm, covering all conventional dry mortar formula aggregates with strong versatility.

• Complete Pre-Startup Inspection: Thoroughly check the tightness of the rotary drum, supporting rollers, transmission gears, sealing components and heat source pipeline before startup. Verify the normal operation of temperature sensors, dust removal system and frequency conversion control system. Overload operation and fault startup are strictly prohibited to avoid mechanical damage and safety accidents.
• Standard Preheating & Feeding Rules: Perform 15-20 minutes constant-temperature preheating before formal feeding to stabilize internal heat balance and ensure uniform drying. Prohibit sudden large-volume feeding and feeding of hard sundries, large-particle stones and metal impurities to prevent drum blockage, overload jamming and abnormal wear.
• High-Temperature Safety Management: The equipment runs under continuous high-temperature working conditions. It is forbidden to touch the drum shell, combustion chamber and hot air pipeline during operation to prevent scalding. Keep the workshop well ventilated, strictly away from flammable and explosive materials, and standardize heat source operation to eliminate fire hazards.
• Standard Parameter Adjustment: Only professional technicians are allowed to adjust drying temperature, drum rotating speed and feeding parameters. Unauthorized modification of operating parameters is forbidden to avoid material over-drying, insufficient dehumidification, equipment overheating and system alarm faults.
• Regular Daily Maintenance & Cleaning: Clean residual caked materials and surface dust inside the drum after daily shutdown to prevent accumulated materials from affecting heat exchange efficiency. Regularly lubricate transmission parts, check the wear of liner plates and lifting plates, and replace aging sealing strips and vulnerable parts in time.
• Standard Shutdown & Emergency Handling: Stop feeding first before shutdown, keep the drum running until all internal materials are completely discharged, then turn off the heat source and cut off the power supply. In case of abnormal noise, high-temperature alarm, material blockage or system failure, stop feeding immediately, cool down the equipment gradually and troubleshoot before restarting production.

The 15-20 TPH dry mortar dryer is dedicated to high-yield production demands of large-scale dry mortar factories and building material raw material processing bases. It serves as the core front-end supporting equipment for large and medium-sized dry mortar production lines, widely applicable to raw material drying for tile adhesive, interior and exterior wall putty powder, waterproof mortar, thermal insulation mortar, self-leveling mortar, masonry and plastering mortar, and repair mortar. It perfectly matches high-capacity mixing systems and fully automatic packaging & palletizing lines, adapting to 24-hour continuous mass industrial production. It is suitable for standardized fixed factory production and centralized large-batch raw material drying and processing scenarios.

Q1: What is the maximum raw material moisture this dryer can handle?
A1: This upgraded model supports raw sand with initial moisture up to 18%, higher than conventional small dryers. It can stably dry high-humidity raw materials and control the final moisture within 0.5%-1%, fully meeting high-standard dry mortar production requirements.

Q2: What are the advantages compared with 10-15TPH dryer?
A2: It features larger hourly output, higher thermal efficiency, upgraded wear-resistant structure and stronger overload resistance. It perfectly matches high-speed full-automatic mortar production lines, supports long-term high-load operation, and has lower unit energy consumption for mass production with higher overall cost performance.

Q3: How to solve uneven drying of materials?
A3: Uneven drying is mainly caused by insufficient preheating, unstable heat source temperature, excessive instantaneous feeding or blocked internal lifting plates. Standardize preheating time, control uniform feeding volume, and clean internal sundries regularly to ensure consistent drying effect.

Q4: Is multiple heat source switching supported?
A4: Yes. The equipment is compatible with natural gas, diesel, biomass, coal and electric heating. Users can flexibly switch heat sources according to factory environmental protection policies, energy costs and on-site conditions.

Q5: Is the operation complicated for new operators?
A5: Adopts intelligent integrated PLC touch screen control with preset standard drying recipes. It realizes automatic constant temperature operation and fault self-detection. Workers can master daily operation and simple maintenance after short-term training.

Q6: Why is three-pass structure more advantageous?
A6: The nested three-pass structure greatly extends the heat exchange stroke and time between materials and hot air, with higher heat utilization rate, more uniform drying and smaller floor space. It effectively avoids the low efficiency and high energy consumption defects of traditional single-cylinder dryers.

Q7: Can it support long-term 24-hour continuous production?
A7: Absolutely. The equipment is designed for heavy-duty industrial working conditions, with upgraded wear-resistant and high-temperature resistant structure. It can stably maintain 15-20TPH high output for 24-hour uninterrupted operation, fully adapting to large-batch and high-order production modes of large mortar enterprises.
