Iron-ore crushing and grinding device

Abstract

The invention discloses an iron ore crushing and grinding device, which comprises a main body, a crushing cone, a lifting auger, a fixed sieve plate, a movable sieve plate and an eccentric shaft sleeve; a feeding hopper is provided on the upper side of the main body; The inside of the main body is fixed with a partition, and the partition divides the interior of the body into a crushing chamber and a fine crushing chamber. The crushing chamber is located on the upper side of the fine crushing chamber; two crushing rollers are symmetrically arranged inside the fine crushing chamber; The bottom of the chamber is fixed with a fixed sieve plate, the fixed sieve plate has a conical structure, and a number of sieve holes are evenly opened on the fixed sieve plate; two lifting augers are symmetrically installed on the left and right sides of the fine crushing chamber. The invention preliminarily crushes the iron ore by setting the crushing cone, which is convenient for subsequent fine crushing treatment; it is also equipped with a fixed sieve plate, a movable sieve plate and a lifting auger to carry out circular crushing treatment on the iron ore, improving the crushing efficiency and crushing efficiency. Evenness.

Description

technical field [0001] The invention relates to iron ore processing equipment, in particular to an iron ore crushing and grinding device. Background technique [0002] Iron ore is a mineral aggregate containing iron element or iron compound that can be used economically. Natural ore (iron ore) is gradually extracted from natural ore (iron ore) after crushing, grinding, magnetic separation, flotation, re-election and other procedures. An important raw material for enterprises. [0003] Ore crusher is one of the necessary equipment in the process of ore processing. In the process of iron ore processing, it is necessary to crush large pieces of iron ore first, and then carry out subsequent smelting; the existing iron ore crushing device is crushing At this time, the ore particles with smaller particles are easy to accumulate at the bottom of the crushing device without being crushed, resulting in low crushing efficiency and uneven crushing, which seriously affects the subseque...
