Abstract
The invention belongs to the technical field of mineral separation in mines, and in particular relates to an anti-segregation ore-blending system of a high-pressure roller mill. The system is characterized by comprising a distributing-blending system, an aggregate conveying sealing-tape machine and a stirring system, wherein the distributing-blending system comprises a raw material cabin, an oversize return cabin, a raw material cabin chute, an oversize return cabin chute, a pneumatic valve on an outlet of the raw material cabin chute and the oversize return cabin chute, a discharging sealing-tape machine I, a discharging sealing-tape machine II, and a head funnel on a junction of the discharging sealing-tape machine I and the discharging sealing-tape machine II, and the aggregate conveying sealing-tape machine is arranged below the outlet of the head funnel. New materials and oversize returned materials are respectively fed into the raw material cabin and the oversize return cabin, and the pneumatic valve is used for controlling the mixing proportion of the new materials and the oversize returned materials according to the granularity and the ore properties of the new materials and the oversize returned materials to realize reasonable ore-blending, so that the material segregation caused by the condition that the new material and the oversize returned material are fed into the same cabin is avoided, and the continuity and the stability of feeding of the high-pressure roller mill can be guaranteed.
Description
Technical field
The invention belongs to the mine ore dressing technical field, especially relate to the anti-segregation ore blending system of a kind of high-pressure roller mill.
Background technology
High-pressure roller mill is that German Schoenert teaches the design eighties in 20th century, makes two roller disintegrating apparatus of material fragmentation under static pressure state with the lamination smashing principle, in the metallurgical mine field, is widely applied in recent years.The technological process generally adopted at present is the closed circuit flow process of high-pressure roller mill, and configuration coarse grain vibratory sieve after high-pressure roller mill, carry out classification by the high-pressure roller mill product, oversize with newly feed material together with as the high-pressure roller mill feed.While working due to high-pressure roller mill, must guarantee to be full of material between two rollers, it is too large that size distribution on the roller cross direction can not differ, therefore, if entering the material of high-pressure roller mill has produced serious segregation and will cause the skewness on roller is wide, to make high-pressure roller mill generation deflection, and cause two roller gaps to have big difference and frequent stop jumping repeatedly.So, in order to guarantee the continuous and steady operation of high-pressure roller mill, guarantee that continuity and the uniformity of feeding will become very important.But in the prior art, virgin material and the upper returns of sieve that high-pressure roller mill sieves closed circuit flow process feed same ore storage bin often, because the upper difference of returns on granularity and ore properties of virgin material and sieve, segregation phenomena very easily appears in ore storage bin, also can produce segregation in sealing-tape machine transportation and discharge process in addition, to high-pressure roller mill, running brings adverse effect.
Summary of the invention
The purpose of this invention is to provide the anti-segregation ore blending system of a kind of high-pressure roller mill, solve high-pressure roller mill and sieve virgin material and the sieve segregation problem that above returns produce in ore storage bin, adhesive tape transportation in closed circuit flow process.
The objective of the invention is to realize by following technical proposals:
