Description

Technical Field

[0001] The utility model belongs to the field of bulk material transportation and batching, and relates to a three-dimensional two-stage ore batching process system. Background Art

[0002] Batching process is a kind of pre-batching of raw materials. The pre-batching process can reduce the material inventory demand, improve the utilization rate of raw materials, reduce resource waste, and batching can optimize the production process to reduce the demand for large equipment, thereby reducing equipment investment and operating costs. Batching process can also reduce material segregation, which helps user units improve product quality and ensure product consistency.

[0003] Existing batching technologies mainly include systematic material field processes and independent forced mixing technologies. The material field processes mainly include conveying systems, batching troughs, quantitative feeding devices, stacking conveying systems and stackers, reclaimers and output systems. The materials are unloaded at fixed points and then batched by using batching troughs, and then directly taken out by flat laying. There are disadvantages such as low batching flexibility and large space requirements for the process system. The forced mixing technology mainly includes input systems, forced mixing batching troughs, professional mixing equipment (such as agitators, mixers, etc.), output systems, etc., and professional equipment is used to mix materials locally. The forced mixing process can only achieve material homogenization in an extremely short period of time, and cannot achieve stable batching over a longer period of time. There are disadvantages such as large material fluctuations and low stability at different stages.

[0004] Due to the shortcomings of the existing batching process, such as complexity, low flexibility, large land requirements, high equipment costs, and low material stability, in order to reduce equipment and civil engineering investment and improve product quality, a new batching process is proposed to replace the existing high cost of direct flat-laying in the mixing yard and the unstable strong mixing process.
