Ore crushing machine with multistage continuous crushing function

Abstract

The invention discloses an ore crushing machine with a multistage continuous crushing function. The ore crushing machine comprises a first-stage crushing device, a second-stage crushing device and a collecting device which are sequentially arranged from up to bottom according to the ore flowing direction. The first-stage crushing device comprises an inverted conical channel and a crushing roller arranged in the channel. A plurality of layers of crushing teeth A are arranged on the inner surface of the channel. A plurality of layers of crushing teeth B are arranged on the outer surface of the crushing roller. The crushing roller is in transmission connection with a driving device A. The ore crushing machine has the beneficial effects that by the adoption of the ore crushing machine, multistage crushing can be achieved, and the crushing efficiency and crushing precision are high; by arranging the channel, materials can be added so that the materials can be supplemented in time, thus, the continuous machining function is achieved, and the crushing efficiency is improved; and by arranging the crushing teeth A and the crushing teeth B, the contact area between the ore crushing machine and the materials can be increased, and the crushing efficiency and crushing precision of the materials are improved.

Description

technical field [0001] The invention relates to the field of pulverizers, in particular to an ore pulverizer capable of multi-stage continuous pulverization. Background technique [0002] In the metallurgical industry, a large amount of ore needs to be ground for smelting; in the building material industry, cement production needs to grind the stone and add it to the raw material. In the prior art, ores and stones are generally ground by a ball mill. The ball mill has a huge drum, and steel balls of different diameters are installed in the drum. When the ball mill is working, the granular materials are loaded into the drum, and the drum is driven to rotate. The steel balls and materials are transported from the low end of the drum to the high end during the rotation process, and fall from the high end to the bottom of the drum. When falling to the bottom, the steel balls and materials collide with each other, and the materials are ground. [0003] When the ball mill is work...

AI Technical Summary

Problems solved by technology

[0003] When the ball mill is working, because a lot of steel balls and materials are filled in the drum, the load of the drum rotation increases, and the power loss of the machine is relatively large; when the steel balls fall from the top of the drum, some steel balls do not hit the bottom material, but Impacting on other steel balls causes a lot of energy waste; because in many cases the collision occurs between the steel balls, the abnormal wear of the steel balls increases, resulting in a double waste of energy and steel ball materials. Therefore, Traditional ball mills have large power loss, low mechanical efficiency, and high production costs, which can no longer meet the needs of energy-saving and consumption-reducing production development.
