Our granulation dryer is a professional rotary drying equipment matched with dry mortar production lines. It is mainly used to reduce the moisture content of sand, granular mineral powder, granulated admixtures and other raw materials. The equipment consists of rotary drum, hot air furnace, feeding device, discharging unit, dust removal system, transmission mechanism and intelligent temperature control cabinet. Wet materials contact with high-temperature hot air inside the rotating drum for continuous heat exchange to achieve uniform dehydration. Stable moisture control ensures the subsequent batching, mixing and finished mortar quality. It supports continuous 24-hour operation and can be flexibly integrated into new or existing mortar production lines.
- Uniform drying & stable moisture control: Rotary rolling structure makes materials fully turn over and contact hot air; moisture can be stably controlled within the required range, avoiding mortar quality fluctuation caused by wet raw materials.
- High thermal efficiency & energy saving: Optimized internal lifting plate design extends material retention time; heat loss is reduced, lowering fuel consumption and operating cost.
- Wear-resistant & long service life: The inner drum and lifting plates adopt high-temperature and wear-resistant alloy steel; anti-corrosion treatment is applied to cope with abrasive granular raw materials.
- Complete environmental protection configuration: Equipped with pulse dust collector and waste gas treatment unit; low dust emission, meets local environmental discharge standards.
- Intelligent temperature automatic control: Real-time monitoring of inlet and outlet temperature; automatic adjustment of air volume and heating power; simple operation and fewer on-site workers.
- Strong compatibility & easy maintenance: Suitable for silica sand, granular additives, mineral aggregates and other building raw materials; quick-wear parts are easy to disassemble and replace.

- Operators must receive professional training before operation and strictly follow the operation manual; wear high-temperature resistant gloves, goggles and other protective gear.
- Check the fastening parts, supporting rollers, sealing rings, transmission system and dust removal pipeline before startup; remove foreign matters in the drum.
- Preheat the dryer gradually; do not heat up rapidly to avoid thermal deformation of the drum. Feed materials only after the working temperature reaches the set value.
- Do not put metal blocks, large hard sundries and inflammable hazardous materials into the feeding port to prevent equipment damage or fire risk.
- Regularly clean filter cartridges of the dust collector and check the sealing points to prevent air leakage, dust overflow and heat efficiency reduction.
- If abnormal vibration, loud noise, smoke or material blockage occurs, cut off the heating source first, then stop feeding; do not open the inspection door when the drum is still hot.
- Keep the control cabinet dry and away from high-temperature pipelines; inspect the temperature sensor and safety interlock device periodically.
- Cut off the main power supply before maintenance and wait until the drum temperature drops to safe temperature.
- Dry mortar production line: Drying quartz sand, river sand and granular additives for masonry mortar, plastering mortar and tile adhesive.
- Building material plant: Dehydration of mineral powder, granular fillers and lightweight aggregates.
- Sand processing plant: Drying manufactured sand and washed sand for construction.
- Chemical & mineral industry: Drying granulated raw materials, inorganic fillers and granular binders.
- Stabilized soil and road base material production: Drying granular aggregates for road mixing materials.
Q1: Can this dryer be matched with our existing dry mortar production line? A: Yes. We can customize the capacity, feeding height and layout according to your existing mortar line, to realize seamless connection with batching silos and conveyors.
Q2: What heating source options are available? A: Multiple heating modes are optional, including natural gas, biomass, coal and diesel. We will recommend the most suitable solution based on your local fuel cost and environmental requirements.
Q3: How to guarantee the final moisture of dried sand? A: Equipped with real-time temperature monitoring and adjustable feeding speed. Our technicians will debug parameters on site to stabilize the outlet moisture within your target range.
Q4: What is the delivery and installation cycle? A: Standard models are delivered within 20–35 working days. Installation and commissioning usually take 7–18 days, depending on site layout and supporting configuration.
Q5: What is the warranty period? A: The main body enjoys a 12-month warranty, excluding quick-wear parts such as lifting plates and sealing strips. We provide long-term spare parts supply and remote technical support.
