Method and device for comminuting ore

Abstract

The invention relates to a device and method for comminuting ore and / or in particular slag, comprising an ore feeding unit for feeding ore to be comminuted to a pulverizer, wherein the pulverizer is composed at least of two comminuting elements (30, 40) that can be moved relative to each other, which elements form at least one comminuting space for the ore to be comminuted with each other such that, by a relative movement in the form of a rotation of at least one of the two comminuting elements (30, 40), the ore to be comminuted is pulverized in that one or more accelerating elements (35), in particular protrusions (35), are provided on at least one of the comminuting elements (30,40), said accelerating elements being arranged in particular on the end face of at least one of the two comminuting elements (30, 40); and accelerating and comminuting the ore to be comminuted by the rotation of one of the two comminuting elements (30, 40). An intermediate space (60) is provided between the two comminuting elements (30, 40) and / or in at least one of the two comminuting elements, through which gap the pulverized ore, during the rotation, is transported from the center of rotation toward the outside and away by the two comminuting elements (30, 40), and an outlet unit (14) is provided, which is connected to the intermediate space (60) and through which the pulverized ore is discharged.

Description

technical field [0001] The invention relates to a method and a device for comminuting ores, stones and / or in particular slag, which can be comminuted both in a wet process with added water and in a dry process without water, in particular in an environmentally friendly manner. [0002] For the extraction of raw materials, there is a huge demand for environmentally friendly methods and devices, especially aimed at protecting the health of the persons involved. The traditional ore crushing process is harmful to the health of workers, and the lungs of these workers are affected along with the accumulation of dust. [0003] Furthermore, there is a need for improved methods and apparatus for mining, especially processing ore, so as to save energy and reduce damage to the environment. Background technique [0004] Used as a technique for crushing ore, ball mills have been known for a long time. The ore is rotated together with the iron balls until a desired ore fineness is reach...

AI Technical Summary

Problems solved by technology

Therefore, the operating cost and energy consumption of this ball mill is very high

Furthermore, due to the impact of the sphere, the rotating drum for crushing wears a lot, so after a short period of use, both the sphere and the cylinder need to be renewed.

In addition, when using a ball mill, in order to achieve the expected effect, it is necessary to use a separate crushing element to process the crushed ore and then use one or more ball mills connected back and forth, otherwise it is difficult to achieve effective crushing

[0006] In addition, this kind of ball mill is not suitable for the mixture of ore and slag or only for the crushing of slag.
