Problems solved by technology

The crushing cone of the fine crusher is a wearing part that wears quickly. After the new crushing cone is installed and operated for a period of time, the wear of the two cones increases, especially the lower part of the two cones wears quickly, especially near the ore discharge port. The nip angle decreases, the ore discharge opening increases, the ore is easy to pass through, and the productivity increases, but the crushing ratio decreases and the particle size of the broken ore increases, which cannot meet the requirements of the process.

Embodiment Construction

[0025] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0026] A segmented and staged continuous ring crushing method of the present invention is characterized in that a cone crusher is used, and on the basis of the three crushing stages of the existing coarse crushing, medium crushing and fine crushing, the fine crushing stage Divided into 2-3 ore-breaking process sections, each of which is composed of successive ore-feeding devices, ore-crushing devices and ore-discharging devices, and a screening machine is installed between each crushing process section, the first section The movable cone and fixed cone of the ore crushing device adopt new parts, and then the movable cone and fixed cone in the crushing section adopt the movable cone and fixed cone recovered after the previous crushing device has been used and scrapped. The first process section is the primary fine Crushing, accepting the me...

Abstract

The present invention relates to ore breaking technology, and is especially one sectional cascade ore breaking method and ore crushing apparatus. The ore crushing apparatus consists of two or three cascade ore crushers, each of which includes one ore feeder, one ore crushing mechanism comprising two or three ore crushing sections and sieves between ore crushing sections, and one ore discharger. In the first ore crushing section, new movable cone and static cone are mounted, while in the subsequent ore crushing sections, used movable cone and static cone are mounted. The present invention has reduced movable cone and static cone consumption, well matching between the meshing angle and ore size, raised ore breaking and small size of crushed ore.

Description

technical field [0001] The invention relates to the technical field of ore crushing methods, in particular to a segmented and staged chain crushing method and segmented and staged chain cone crushing equipment. Background technique [0002] The current ore crushing is divided into three crushing stages of coarse crushing, medium crushing and fine crushing. Each stage uses different types of crushers with different specifications. Each stage is no longer divided into particle size and stage, new and old The cones are not used separately, one cone is one machine, and the new cone is used once to be scrapped after installation. The crushing cone of the fine crusher is a wearing part that wears quickly. After the new crushing cone is installed and operated for a period of time, the wear of the two cones increases, especially the lower part of the two cones wears quickly, especially near the ore discharge port. The bite angle decreases, the ore discharge port increases, the ore ...
