Ore crushing device capable of adjusting smashing distance

Abstract

The invention relates to the technical field of iron and steel smelting, in particular to an ore crushing device capable of adjusting a smashing distance. The ore crushing device capable of adjustingthe smashing distance comprises a machine frame, a first pressing roller and a second pressing roller, wherein the first pressing roller and the second pressing roller are positioned on the machine frame. The machine frame is provided with two sliding rods which are symmetrically arranged, the second pressing roller is arranged between the two sliding rods, first sliding blocks are separately arranged at the two ends of the second pressing roller, the two first sliding blocks are correspondingly arranged on the two sliding rods in a sleeving mode, and the first sliding blocks are provided withbolts for fixing the first sliding blocks to the sliding rods. The second pressing roller is connected with a driving device, a crushing funnel is arranged above the machine frame, and an extrusion column in the crushing funnel preliminarily crushes ore. According to the ore crushing device capable of adjusting the smashing distance, and the extrusion column is arranged in the crushing funnel forpreliminarily crushing the large ore so that the crushed small ore cannot damage the pressing rollers; and the first sliding blocks on the second pressing roller moves on the sliding rods to change agap between the first pressing roller and the second pressing roller, so that the required ore size is independently selected.

Description

technical field [0001] The invention relates to the technical field of iron and steel smelting, in particular to an ore crushing device capable of adjusting the crushing distance. Background technique [0002] In the field of iron and steel smelting, it is often necessary to use a crushing device to crush the mined ore, and then transport and smelt it. However, due to the simple structure of the existing ore crushing device, the ore cannot be crushed sufficiently, and the crushing effect is poor. The efficiency is low and cannot meet the needs of mining. [0003] The Chinese invention patent with the application number of 201810014560.0 discloses a step-by-step rolling ore crushing device, which is equipped with a step-by-step rolling device, which includes a number of roller sets arranged in sequence from top to bottom. There is a gap between the first pressure roller and the second pressure roller, and the distance between the first pressure roller and the second pressure...
