10-15TPH Rotary Sand Dryer Dry Mortar Rotary Dryer Industrial

The 10-15 TPH dry mortar dryer is a professional three-pass rotary drying equipment independently optimized for medium and large-scale dry mixed mortar production lines. It is mainly used for drying raw river sand, quartz sand and aggregate materials for dry mortar, solving the core problem of unstable moisture of raw materials affecting mortar mixing quality and packaging efficiency. Adopting advanced three-layer nested rotary drum structure and circulating hot air drying technology, the equipment realizes continuous feeding, uniform heating, rotary flipping and automatic discharging. It effectively reduces the raw material moisture from 12%-15% to below 0.5%-1%, fully meeting the production standards of tile adhesive, putty powder, waterproof mortar, thermal insulation mortar and other high-precision dry mortar products. With stable hourly output of 10-15 tons, low energy consumption and high thermal efficiency, it is the essential front-end drying core equipment for standardized and high-efficiency dry mortar production lines.

• High Efficient Drying & Stable Output: Adopts three-pass rotary circulating drying structure, which prolongs the heat exchange path between materials and hot air. The thermal efficiency reaches over 80%, far higher than traditional single-cylinder dryers. It maintains a continuous stable output of 10-15 tons per hour, completely matching the operating speed of medium and large dry mortar mixing and packaging lines without production bottlenecks.
• Precise Moisture Control: Equipped with intelligent temperature sensing and frequency conversion speed regulation system. The drum rotating speed and feeding speed can be adjusted in real time according to material humidity and particle size. The final material moisture is stably controlled within 0.5%-1%, ensuring uniform drying effect and consistent mortar product quality.
• Durable & Wear-Resistant Structure: The inner drum is made of thickened high-strength alloy steel plate, which is 3-4 times more wear-resistant than ordinary steel plates. The whole machine adopts anti-high temperature and anti-corrosion spraying treatment, adapting to long-term high-temperature and abrasive working conditions of mortar raw sand drying, with ultra-long service life.
• Energy-Saving & Environmentally Friendly: Equipped with closed hot air circulation and waste heat recovery system, which greatly reduces heat loss. It supports multiple heat sources such as natural gas, diesel, biomass and coal. Meanwhile, it is matched with professional dust removal interface to effectively control dust overflow and meet industrial environmental protection emission standards.
• Intelligent & Easy Operation: Adopts PLC touch screen automatic control, realizing one-key start-stop, automatic temperature adjustment and fault self-detection. The equipment supports 24-hour continuous uninterrupted operation, with simple daily operation and low dependence on manual workers.
• Wide Material Adaptability: It can stably dry various granular raw materials required for dry mortar, including river sand, quartz sand, manufactured sand and fine aggregate. It is compatible with multiple raw material specifications and can adapt to diversified mortar production formulas.

• Pre-Startup Safety Inspection: Check the tightness of the drum, transmission gears, supporting rollers and sealing parts before starting the machine. Confirm that the heat source system, temperature sensor and dust removal device are in normal working state. It is forbidden to start the machine with faults or overload.
• Standard Heating & Feeding Operation: Preheat the dryer for 10-15 minutes before formal feeding to avoid uneven drying caused by sudden temperature difference. It is forbidden to feed excessive materials at one time or mix ultra-large particles and hard sundries to prevent material blockage and drum overload operation.
• High-Temperature Safety Protection: The equipment operates at high temperature during working. It is strictly prohibited to touch the drum shell, heat pipeline and burner parts to avoid scalding. Keep the workshop ventilated and away from flammable and explosive materials to ensure production safety.
• Prohibited Parameter Modification: Professional technicians are required to adjust temperature, rotating speed and feeding parameters. Unauthorized arbitrary modification is forbidden to avoid excessive drying, insufficient drying or equipment overheating failure.
• Daily Maintenance & Dust Cleaning: Clean internal residual materials and surface dust regularly to prevent material caking from affecting heat exchange efficiency. Regularly lubricate transmission components, check the wear of liner plates and sealing strips, and replace vulnerable parts in time.
• Shutdown & Emergency Handling: Stop feeding first before shutdown, and continue running the drum until all internal materials are discharged, then cut off the heat source and power. In case of abnormal noise, high temperature alarm or material blockage, stop feeding immediately, cool down the equipment and troubleshoot.

The 10-15 TPH dry mortar dryer is specially applicable to medium and large-scale dry mortar production enterprises and building material raw material processing bases. It is the core front-end supporting equipment for dry mortar production lines, widely used in drying raw sand and aggregate for tile adhesive, interior and exterior wall putty powder, waterproof dry mortar, thermal insulation mortar, self-leveling mortar, masonry and plastering mortar. It perfectly matches the supporting use of medium-capacity dry mortar mixing lines, meeting the continuous drying demand of large-batch raw materials. It is suitable for both fixed factory standardized production and centralized raw material drying and processing scenarios.

Q1: What is the applicable raw material moisture range of this dryer?

A1: It is designed for conventional wet mortar raw materials with initial moisture within 15%. After drying, the final moisture can be stably controlled below 1%, fully meeting the raw material standard requirements of all dry mortar products.

Q2: Can the drying temperature and speed be adjusted freely?

A2: Yes. The equipment adopts frequency conversion speed regulation and intelligent temperature control system. Users can adjust drum speed and hot air temperature according to material humidity and output demand to ensure the best drying effect.

Q3: Why is the material drying uneven?

A3: The main reasons include insufficient preheating, excessive feeding volume, unstable heat source temperature or blocked internal lifting plates. The problem can be solved by standard preheating, controlling feeding capacity and cleaning internal sundries regularly.

Q4: What heat sources can the equipment support?

A4: It supports multiple flexible heat sources such as natural gas, diesel oil, biomass fuel, coal and electric heating, which can be selected according to user’s factory conditions, energy cost and environmental protection requirements.

Q5: Is the equipment easy to operate for new workers?

A5: The whole machine adopts integrated PLC automatic control with simple operation logic. It supports one-key operation and automatic constant temperature operation. Workers can master the operation and daily maintenance after simple training.

Q6: What is the advantage of three-pass structure compared with single-cylinder dryer?

A6: The three-pass nested structure greatly prolongs the heat exchange time, with higher thermal efficiency, more uniform drying and lower energy consumption. It avoids material waste and low drying efficiency of traditional single-cylinder equipment, with better continuous operation stability.

Q7: Can it support 24-hour continuous production?

A7: Yes. The equipment is designed for heavy-duty industrial continuous operation, with wear-resistant and high-temperature resistant structure. It can stably maintain 10-15TPH hourly output for long-term uninterrupted production, suitable for large-order batch production.
