When selecting lifting and conveying equipment for a sand and gravel production line, the following factors are primarily considered:

· Material characteristics: Particle size, moisture content, adhesiveness, abrasiveness, temperature.

· Process requirements: Conveying capacity (t/h), conveying distance, lifting height, installation angle.

· Site layout: Whether the production line is arranged horizontally or vertically, and whether the space is compact.

· Investment and operational costs: Equipment purchase cost, installation difficulty, energy consumption, and maintenance costs.

· Environmental requirements: Whether a fully sealed design is needed to prevent dust leakage.
