The frequency of delivery, in addition to coal mining because of mine conveyor conveying capacity, simple structure, maintenance convenience, low cost, general strong advantages, and is widely used in various occasions, loading, shipment, reproduced or accumulate temperature loose density is 800kg. By single or multiple units of synthetic transportation system to transport coal, according to process requirements can be arranged into a horizontal or inclined form, mine conveyer can meet the horizontal or inclined conveying requirements, but also can be used with a convex arc concave arcs and straight line segment combination form. Conveyor permits delivery of materials depending on the bandwidth, speed, groove angle and inclination, depending on the bulk material.
The design of mine conveyor conveyor with stacking angle rho = 20 degrees, the belt speed: v=1.6m/s; tilt factor: k = 1, the largest shipments of 400t / h.
