Coal slime dryers have specific requirements for the particle size of the coal slime to be dried, which directly affects the drying efficiency, energy consumption, final product quality, and equipment operational stability. So, what are the particle size requirements for coal slime in a coal slime dryer?

1. Particle Size Range: The particle size of coal slime is generally required to be between 0-15mm, but the specific range may vary depending on the equipment model and process requirements. Particles that are too large will lead to uneven drying and increased energy consumption; particles that are too small will increase dust, affecting the operating efficiency and safety of the equipment.

2. Particle Size Uniformity: The particle size of the coal slime should be as uniform as possible to avoid uneven mixing of large and small particles. Uneven particle size will lead to inconsistent drying effects and affect product quality.

3. Pretreatment: Before entering the coal slime dryer, the coal slime can be pretreated by a crusher or screening machine to ensure that the particle size meets the requirements. Pretreatment can improve the uniformity of the coal slime and drying efficiency, and reduce equipment wear and energy consumption.

4. Monitoring and Adjustment. Regularly check the particle size of the coal slime and monitor it using screening equipment. Adjust the pretreatment equipment in a timely manner to ensure that the particle size of the coal slime entering the dryer always meets the requirements.
