Abstract: A big data processing method for a segment-based two-grade deep learning model. The method includes: step (1), constructing and training a segment-based two-grade deep learning model, wherein the model is divided into two grades in a longitudinal level: a first grade and a second grade, each layer of the first grade is divided into M segments in a horizontal direction, and the weight between neuron nodes of adjacent layers in different segments of the first grade is zero; step (2), dividing big data to be processed into M sub-sets according to the type of the data and respectively inputting same into M segments of a first layer of the segment-based two-grade deep learning model for processing; and step (3), outputting a big data processing result. The method of the present invention can increase the big data processing speed and shorten the processing time.

Abstract: A modular magnetic separation apparatus set has a processing capacity increased by increasing the number of the unit modules of the magnetic separation apparatus set, being suitable for all enrichment processes of magnetic minerals. One modular unit is defined with a separation wheel and its two neighboring magnet-concentration cores and two corresponding excitation coils and a charging hopper and a discharging hopper of magnetic materials, each unit being combined of multiple identical modular units. The modular magnetic separation apparatus solves the conflicts between the transportation of apparatus after the enlargement and the height and width restrictions on general roads, including more reasonable conditions for separate transportation.
