Sand Dryer Particle Size Requirements for Applicable Materials

Sand dryers are widely used in construction, chemical, and metallurgical industries, primarily for removing moisture from sand to meet usage standards. When selecting and using a sand dryer, the particle size of the sand is a crucial technical parameter, directly affecting the drying effect and operating efficiency of the equipment.

1. Influence of Particle Size Range

Sand dryers have specific requirements for sand particle size, typically suitable for sand with a particle size between 0.3mm and 5mm. If the sand particle size is too large or too small, it may affect the drying effect and the equipment's lifespan.

- Oversized Particles: If the sand particle size is too large, it may increase internal wear on the equipment, especially in the dryer's drum and blades. Simultaneously, large sand particles tend to accumulate during the drying process, leading to uneven heat distribution and affecting drying efficiency.

- Undersized Particles: If the sand particle size is too small, especially fine sand (particle size less than 0.3mm), it easily generates dust during the drying process, not only affecting the environment but also potentially causing equipment blockage or heat loss.

2. Requirements for Particle Size Uniformity The particle size uniformity of sand is also a crucial factor affecting drying efficiency. If the sand particle size distribution is uneven, some sand may be over-dried while others remain incompletely dried during the drying process. Therefore, it is recommended to screen the sand before using a sand dryer to ensure uniform particle size.
