Ore mill with grading function

Abstract

The invention provides an ore mill with a grading function. The invention is characterized by comprising a ball mill, a grading device, a bearing seat and a transmission gear, wherein the grading device is connected with the ball mill; the bearing seat is respectively and rotatablely connected with the ball mill and the grading device through bearings; the transmission gear is connected with the ball mill; the ball mill is composed of a barrel body, an ore feed end cover and an ore discharge end cover, and the ore feed end cover and the ore discharge end cover are respectively provided with a hollow shaft and are arranged on both ends of the barrel body; the transmission gear is composed of a main gear ring, a pinion and a motor which are arranged on the outer side of the ore discharge end of the ball mill shell; the grading device is a grading barrel body which is provided with a screen mesh in the circumferential direction; one end of the grading barrel body is provided with an ore feed end cover with an ore feed port; the ore feed end cover is connected with the hollow shaft of the ore discharge end cover of the ball mill barrel body through a flange; the other end of the grading barrel body is provided with the ore discharge end cover with a hollow shaft; the ore discharge end cover is rotatablely connected with the bearing seat through a bearing; a fine fraction ore collection box is arranged under the grading barrel body; and a coarse fraction ore collection box is arranged under the ore discharge end cover of the grading barrel body. The ore mill shortens the technological process and saves the investment.

Description

technical field [0001] The invention relates to the technical field of mineral processing equipment, in particular to a grinding machine with a classification function. Background technique [0002] In the process of mineral processing, in order to achieve the purpose of separation and separation of useful minerals and gangue minerals, it is necessary to grind the ore to a certain fineness and then sort it. In the current professional textbooks and actual production process, the combination of grinding equipment and grading equipment is generally used to obtain qualified grade materials. The method is to first feed the ore into the grinding equipment for grinding. The material discharged through the grinding equipment is a mixture of qualified grades and unqualified grades. The discharged materials need to be pumped or flowed into the classification equipment for classification. Divide into thick and thin products and then deal with them accordingly. Either way, either the...
