Whether it is river sand salvaged from the river or washed mechanism sand, the moisture content of 5% or more will be configured with a sand dryer machine, effectively improving the quality of the finished sand and selling for a reasonable price. So, which dryer machine to dry sand? How to choose a suitable sand dryer machine? Let’s take a look.
Currently on the market, more commonly used sand dryers, mainly single pass rotary dryers and triple pass rotary drum dryers, and one suitable for small production of roasting dryers.
Single pass rotary sand dryer
Single pass rotary dryer drives the material through the rotary device of the cylinder body and the lifting plate to carry out the full heat exchange with the high-temperature flue gas; in the process, the moisture in the sand is dried quickly. The single-pass rotary dryer is widely used in slag, clay, river sand, and other materials. It is characterized by reasonable structure, high output, and convenient operation.
Triple pass rotary drum sand dryer
Triple pass rotary drum dryer is the most efficient dryer for drying sand.
The triple pass rotary drum dryer has three cylinders from inside to outside, and the materials circulate in the machine with less heat loss and a high utilization rate; the materials’ final moisture will be below 0.5%. The thermal efficiency of cylinder self-insulation can be as high as 70% or more; compared with the traditional single-cylinder dryer, the thermal efficiency will improve by about 35%. The sand dryer uses a wide range of energy (gas, coal, diesel, electricity, biofuel) and is suitable for various materials production.
Roasting sand dryer
The roasting sand dryer can dry various materials such as peanuts, melon seeds, chili peppers, silt, fly ash, dregs, fruit residue, etc.
A roasting sand dryer, especially for drying nuts, will be a batch of materials dehydrated and unloaded, and then you can dry the next set of materials. It is cheap, but the nut dryer can’t feed continuously, and the output is small.
The roasting sand dryer uses the working principle of imitating nature to dry materials, subverting the traditional natural drying method, significantly improving the work output, saving time, saving labor, and reducing material deterioration, not only to keep the material resources but also to retain the color of the material, and storage is also convenient.
Compared with the single pass rotary sand dryer, the triple pass rotary drum sand dryer has a better processing effect on sand, is more energy-saving and environmentally friendly, and can significantly improve the utilization rate of the heat energy of the dryer, thus effectively improving the drying speed of sand and the quality of the finished product. Moreover, triple pass rotary drum sand dryer, due to higher thermal energy efficiency, cylinder insulation is more robust, so it can effectively prevent heat dissipation through the cylinder, significantly reducing the investment cost of sand drying, to meet the user’s low-investment high-yield production needs.

What factors do you need to consider when choosing a suitable sand dryer?
When choosing a sand dryer machine, there are a few factors to consider:
1. Type of dryer: single pass rotary sand dryer, triple pass rotary drum sand dryer or roasting sand dryer.
2. Capacity and throughput: Determine the quantity of sand you need to dry per hour or day. Choose a dryer with the appropriate capacity to handle your desired throughput.
3. Energy efficiency: Consider the energy consumption of the dryer. Look for energy-efficient models that can help reduce operating costs in the long run.
4. Drying temperature: Different types of sand have different drying temperature requirements. Ensure that the dryer you choose can reach the necessary temperature for efficient drying without causing any damage to the sand.
5. Drying time: Consider the desired drying time for your application. Some dryers are designed for fast drying, while others prioritize gentle drying for delicate materials.
6. Durability and maintenance: Look for a dryer that is built to last and requires minimal maintenance. Check customer reviews and ratings to understand the dryer’s reliability and longevity.
7. Budget: Set a budget for your dryer purchase. Compare different models and brands to find one that fits your budget while meeting your requirements.
Choose a suitable sand dryer machine according to your fuel
Sand dryers can also be categorized according to fuel, such as coal sand dryers, electric sand dryers, diesel sand dryers, etc.
