Vertical mill type selection testing system

The utility model relates to the technical field of construction and machinery, in particular to a vertical mill type selection testing system. The vertical mill type selection testing system comprises a feeding device, a vertical mill host, a dust collector, a fan, an electric control system and an analysis instrument; the lower part of a storage bin of the feeding device is connected with a bucket elevator and a star-shaped feeding valve by pipelines; the star-shaped feeding valve is connected with the vertical mill host by a pipeline; the upper part of the vertical mill host is connected with the position of an inlet at the left side of the dust collector by a pipeline; the fan is arranged at the upper part of the right side of the dust collector; the dust collector comprises a bag type dust collector, a dust collection unloader and a dust collection reamer; the analysis instrument comprises an analytical balance and a negative pressure sieving machine. The vertical mill type selection testing system has the advantages that materials are subjected to performance testing; the grinding characteristics, comprising grindability and abradability, of the materials are accurately analyzed; a guarantee value of unit power consumption of an industrial mill is determined by comprehensively analyzing power consumption, product fineness and abrasion loss; abradability of specific materials also can be effectively calculated; specification type selection and structural design accuracy of the industrial vertical mill are greatly improved.
