A Complete Guide to River Sand Dryer

River sand dryers have long been the industrial dryer of choice for handling sand and gravel in various industries. The sand dryer is highly targeted, and the dried sand has a wide range of applications.

What is the river sand dryer?

The river sand dryer is mainly used to dry materials within a certain humidity range, also known as the sand dryer or sand rotary dryer. The drying temperature of the dryer can reach up to 800°C, and it generally dries lumps, granules, or powders less than 50 mm.

River sand dryer's working principle: During the drying process of the river sand dryer, through the continuous rotation of the cylinder, the wet materials in the cylinder are continuously scattered and thrown, and fully contacted with the hot air flow. The moisture contained is gradually dried to achieve the purpose of drying.

Tip: The dryer cylinder is inclined and placed at an angle of 5° to the ground, which is convenient for discharging.

Applications of river sand dryer

After drying, materials are widely used in construction, chemical industry, casting, metallurgy, and other industries. Such as various sands in the dry powder mortar industry; small-grained clay in the building materials and cement industry; heat-resistant and dust-proof materials in the chemical industry.

River sand dryer price

River sand dryer price is a concerning issue for many customers, but due to various factors, the price can change. Factors that affect the price of dryers:

1. 1Yield factor
   Different purchasers have different output requirements for drying equipment, ranging from 1.9-65 t/h. The higher the output, the higher the performance requirements of the equipment and the higher the price.
2. 2Model size
   There are many models of sand dryers, and the price of different types of dryers is different. In general, the price of large machines will be higher than the price of small machines.
3. 3Production cost
   The main material of the river sand dryer is steel, and steel price directly affects the manufacturing cost of the sand dryer.
4. 4Market demand
   The fluctuating market demand is also a factor in the unstable price of river sand dryers.

Ftmmachinery can independently develop and produce various dryers with complete models, which can effectively control production costs. Therefore, the price of Ftmmachinery sand dryers is more reasonable and cost-effective, which greatly reduces the investment cost of users.

Components of river sand dryer

River sand dryer is simple in its structure and mainly divided into 4 parts:

Drum body

Support system

Transmission system

Thermal system

Drying process auxiliary equipment

The drying production line is composed of a feeder, conveyor, ID fan (induced draft fan), air heating furnace, and cyclone dust collector. According to user needs, Ftmmachinery can provide you with belt conveyors, quantitative feeders, supporting elevators, dust collectors, etc.

Performance advantages of river sand dryer

1. Strong wear-resistance

The main wear parts of the dryers are the drum body and the lifting plates. They are made of wear-resisting manganese plates, which is 3-4 times the wear resistance of ordinary steel plate. The machines use wear-resistant materials, which improve the service life and reduce the maintenance cost.

2. High drying efficiency

The initial moisture content of the material is 15%, and the final moisture is guaranteed to be 0.5-1% or less. It is the first-choice product for drying projects. Stainless steel gaskets are used for sealing at both ports, which can efficiently prevent heat from escaping, and improve the utilization of the hot gas and the drying efficiency.

3. Stable performance

The sand dryers adopt a unique internal structure, which effectively avoids materials sticking to the inner plate. Robust stainless construction requires less maintenance and reduces wear on internal parts, making them more stable in operation.

4. Reliable cooling system

The discharge temperature of the environmentally friendly sand dryers is not higher than 60℃, and they can be directly fed into the material warehouse. The system can prevent the discharge of hot or wet sand under abnormal conditions.

5. Small floor area

Compared with the single-cylinder dryers, the river sand dryers reduce the floor area by about 40%. They are rotary drum horizontal loading machines, which occupy a smaller area while keeping the output unchanged.

6. Better fuel combustion

The sand dryers can burn natural gas, liquefied gas, diesel, methane, biomass pellets, and other fuels, without air leakage. Drying cost is reduced due to more complete combustion of the fuel.

What affects river sand dryer efficiency?

1. Heat source

If the heat source is different when drying sand, the temperature in the furnace is different, resulting in different airflow temperatures in the dryer. If the temperature is too low, the drying time is long, and the output of the equipment will also be affected.

2. Cylinder rotation speed

Generally speaking, the rotation speed of the cylinder determines the drying time of the product. The faster the rotation speed, the faster the materials move inside and are discharged from the cylinder.

3. Degree of moisture

The humidity of materials affects the drying rate of the river sand dryer, so it is generally not suitable to transport fluid materials into the drying equipment. If it contains too much water, a filter press can be installed before the dryer, which can remove a lot of water and improve the working efficiency of the later process.

4. Evaporation intensity of materials

Different materials have different evaporation intensities, which will affect the drying efficiency. The greater the evaporation intensity of the material, the higher the efficiency of the dryer.
