| Product List |
The rotary dryer machine is a professional three-pass rotary drying equipment specially designed for dry mortar production lines. It is mainly used for removing moisture from river sand, manufactured sand and quartz sand, which are the core aggregates of all kinds of dry mortar products. Wet sand with high moisture content easily causes material agglomeration, poor mixing uniformity, unstable mortar strength and low finished product yield. Adopting a three-layer nested rotary cylinder structure and countercurrent hot air circulation technology, the machine achieves full heat exchange between materials and hot air. It can stably dry wet sand with 15%–20% initial moisture down to ≤0.5% final moisture, fully meeting the strict raw material standards for industrial dry mortar production. With high drying efficiency, stable operation and environmental protection design, it is essential front-end drying equipment for modern automatic dry mortar factories.
The three-layer inner-middle-outer cylinder structure prolongs the material heat exchange time. Sand forms a uniform material curtain inside the drum, ensuring thorough and even drying. It completely solves the problem of uneven drying and residual wet core in traditional single-cylinder dryers.
Equipped with internal thermal insulation layer and waste heat recovery system. The thermal efficiency reaches above 80%, which reduces comprehensive energy consumption by more than 30% compared with traditional dryers. It effectively lowers long-term factory operating costs.
The cylinder adopts thickened wear-resistant steel plate, and internal lifting plates are made of high-strength anti-wear materials. It can resist long-term impact and friction of high-hardness sand, ensuring stable mechanical performance and long service life under continuous industrial operation.
Matched with pulse bag dust removal system, the whole machine operates under fully closed negative pressure. No dust overflow occurs during drying process, improving workshop environment and meeting international environmental protection emission standards.
Optimized transmission system and supporting roller structure ensure low noise, low vibration and low failure rate. The equipment supports long-term uninterrupted high-load production, perfectly matching the continuous operation requirement of dry mortar production lines.
It supports multiple heat sources including natural gas, diesel, biomass and coal-fired hot blast stoves. It can be perfectly connected with screening machines, mixing systems and packaging machines to form a fully automatic dry mortar production system.

Check cylinder tightness, transmission system, lifting plate wear condition, hot air pipeline and dust removal system before startup. Ensure no foreign objects inside the drum. Never start the machine with faults.
Maintain continuous and even feeding speed. Overfeeding will cause material blockage, while unstable feeding will lead to inconsistent finished sand moisture. Remove large impurities in advance.
Adjust drying temperature and cylinder speed according to raw sand moisture. Avoid long-time ultra-high temperature operation to prevent cylinder deformation and material scorching.
Do not touch rotating parts and high-temperature pipelines during operation. Cut off the total power supply completely before maintenance, cleaning and component replacement.
Clean residual sand and dust inside the cylinder and dust collector after shutdown. Regularly lubricate bearings and reducers, and replace worn parts periodically.
Stop the machine immediately in case of abnormal noise, blockage, air leakage or temperature abnormality. Do not operate with hidden failures.
Specialized sand drying equipment for masonry mortar, plastering mortar, waterproof mortar, thermal insulation mortar and anti-crack mortar production lines.
Deep dewatering and drying for washed wet sand to meet high-standard building material production requirements.
Drying treatment of quartz sand, manufactured sand and various granular aggregates for powder building materials production.
Drying processing of granular raw materials for thermal insulation materials and refractory products.
Supporting aggregate drying for municipal engineering, road construction and industrial building mortar projects.
A1: It can stably process wet sand with 15%–20% initial moisture and dry it steadily to ≤0.5%, fully compliant with dry mortar production standards.
A2: It features higher thermal efficiency, 30%+ lower energy consumption, more uniform drying effect and smaller floor space compared with single-cylinder dryers, ideal for long-term continuous mortar factory production.
A3: It is mainly caused by unstable feeding speed, blocked hot air pipes or damaged lifting plates. Regular inspection and cleaning can ensure consistent drying quality.
A4: Yes. It supports natural gas, diesel, biomass and coal heat sources, adapting to different factory energy conditions and environmental policies.
A5: Yes. Closed negative pressure dust removal design ensures zero dust overflow during operation, meeting international environmental protection standards.
A6: Yes. We provide customized models from 3t/h to 30t/h according to customer production scale and site conditions.
A7: Keep stable feeding, set reasonable drying temperature, and regularly clean dust blockages in heat exchange system to maximize thermal efficiency and reduce power consumption.
