Description

The invention relates to technological lines for the production of finely ground ore material in the form of pulp and can be used in mining, metallurgical and other industries, in particular, when grinding gold-bearing ores.

Known two-stage line grinding ore with a mill of the first stage of self-or semi-grinding, equipped with a butar, and a ball mill of the second stage [1. V.P. Yashin, A.V. Bortnikov. Enterprise "Lornex" (Canada). "Theory and practice of self-grinding", Nedra Publishing House, 1978, pp. 126-129. 2. V.F. Rams. Modern world practice in the field of ore preparation (foreign experience). Ore beneficiation, 2004, No. 3, p. 42, ore preparation scheme No. a.].

The disadvantage of these two-stage lines is the return of the overburner product (gali) from the butary with high-pressure water (and large sands from the vibrating screen [V.P. Yashin, A.V. Bortnikov. Lornex enterprise (Canada). "Theory and practice of self-grinding" , Nedra Publishing House, 1978, pp. 126-129]) into a self-grinding mill, which reduces its productivity and increases the specific energy consumption, both in the initial ore and in the class - 0.074 mm.

A limiting factor in increasing the productivity of ore preparation lines with self-grinding and semi-self-grinding mills of most enterprises both in Russia and abroad are these head mills.

Also known is a three-stage line for grinding ore with a mill of the first stage of self or semi-grinding, equipped with a butar, a crusher of the second stage of grinding (to finish the gali and return the crushed product to the mill of the first stage) and a ball mill of the third stage [V.F. Rams. Modern world practice in the field of ore preparation (foreign experience). Ore beneficiation, 2004, No. 3, p. 42, ore preparation scheme No. c].

The disadvantage of these three-stage lines is also a decrease in the maximum possible productivity and an increase in the specific energy consumption of the self-grinding or semi-self-grinding head mill, as well as the entire line, due to the return of the crushed product, with a low content of the finished size class, to this mill.

A known line of three-stage grinding of ore, containing an ore hopper with a feeder, sequentially installed a mill of self-or semi-self-grinding of the first stage with butar and estrus for over-mill (gal) and under-mill products, ball mills of the second and third stages of grinding with unloading devices, sump, hydrocyclone, pump and pipelines, where the feed of a feed-through product is connected to a loading device of a coarse grinding ball mill of the second stage, and the supply of a feed-mill product and unloading devices va ball mills, second and third stages are connected to a sump connected to the inlet of the hydrocyclone, the hydrocyclone peskovy pipe is connected to a feeder ball mill third step, and the spout hydrocyclones connected to the reservoir of the finished product [RF patent №67890 from 28.06.07. “The line of three-stage grinding of ore (options)” M. Pk. B02C 15/00].

A known ore grinding line containing an ore hopper with a feeder, a mill of self-or semi-self-grinding of the first stage with butar and estrus, ball mills of the second and third stages of grinding, a group of hydrocyclones, estrus of a sub-bag product and a discharge device of a ball mill of the second stage are connected to a sump of a large product, connected to the inlet pipes of the first group of hydrocyclones, the sand pipes of which, in turn, are connected to the loading device of the ball mill of fine grinding of the third stage, exl. characterized by the fact that the line contains a second group of hydrocyclones, where the discharge device of the fine grinding ball mill of the third stage is connected to a sump of a small product connected to the inlet pipes of the second group of hydrocyclones, and their sand pipes are connected to the loading device of the same mill, drain pipes of the first and second groups of hydrocyclones are connected with the finished product capacity [RF Patent No. 70633 dated 08/20/2007 "Ore grinding line" M. Pk. B02C 15/00].

The main disadvantage of the above two lines of ore grinding ([RF Patent No.67890 of 06/28/07. "Three-stage ore grinding line (options)" M. PC. B02C 15/00] and [RF Patent No. 70633 of 08/20/2007 "Grinding line ore ”M. Pk. B02С 15/00]), is the use in the second stage of grinding ball mills for grinding a pre-mill product (gali), which is the most resistant to ball grinding industrial product (critical size class) of grinding schemes with mills self-or semi-grinding in first stage. Because of this, these lines are characterized by relatively high specific energy consumption for grinding, as well as relatively high capital costs due to the irrational use of expensive ball mills in the second stage of grinding and high operational costs to make up for wear of grinding balls and lining of ball mills. In addition, the persistence of the superbutter product (gali) of the self-grinding or semi-self-grinding mills of the first stage to ball grinding does not significantly increase the productivity of the mills of the first grinding stage due to the increase in the size of the slit of the discharge grill of self-grinding or semi-self-grinding mills and, accordingly, increasing the output of critical material from the mill size. In this case, with an increase in the size of the slit of the discharge grill (the size of the largest piece of gali) of self-grinding or semi-self-grinding mills above a certain size, an additional installation of a crushing apparatus, for example, a cone crusher, is required before the ball mill to finish up the gali (or a large fraction of gali) to optimal for a ball mill initial feed size. The latter leads to an additional increase in capital and operating costs.

Also, the disadvantage of the above two lines of ore grinding is their non-variability, since in the case of using the line of three-stage grinding of ore [RF Patent No. 67890 from 06/28/07. “The line of three-stage grinding of ore (options)” M. Pk. B02C 15/00] without installing a second group of hydrocyclones operating in a closed cycle with a ball mill of the third grinding stage, it is not possible to increase the productivity and energy efficiency of ball mills of the third grinding stage by increasing the classification efficiency of the product of the third grinding stage with an increase in the yield of the finished product, both at the design stage of the enterprise, and in individual production periods. In turn, when using the ore grinding line [RF patent No. 70633 dated 08/20/2007 "Ore grinding line" M. Pk. B02C 15/00)], which operates using the second group of hydrocyclones operating in a closed cycle with a ball mill of the third grinding stage, the enterprise cannot be operated in separate production periods during which the third grinding stage does not limit the performance of the ore grinding line as a whole , and, accordingly, it is not required to increase the performance of ball mills of the third grinding stage by increasing the classification efficiency of the product of the third grinding stage with an increase in the yield of the finished product and, therefore, during these production periods, the enterprise cannot refuse to use the second group of hydrocyclones of the third grinding stage with the corresponding auxiliary units and mechanisms, and, in fact, work according to the technological scheme of the three-stage ore grinding line [RF Patent No. 67890 dated 06/28/07. "The line of three-stage grinding of ore (options)" M.Pk B02C 15/00]. In addition, in the well-known ore grinding line [RF patent No. 70633 dated 08/20/2007 "Ore grinding line" M. Pk. B02C 15/00)], both on an ongoing basis of the enterprise’s work and in individual production periods, it is not possible to send the ball mill product of the second grinding stage to the second group of hydrocyclones to classify it together with the ball mill product of the third grinding stage, which, in many cases, may be more appropriate, since the particle size distribution of the products of the second and third stages of grinding may be more similar than the particle size distribution of the products of the first and second stages of grinding, and traces tion, the joint product classification second and third grinding steps, in these cases, be more efficient than co-product classification of the first and second grinding steps.

The analysis of the patent literature did not reveal the known technological schemes, methods, and lines for grinding ore, which avoids the complex of disadvantages inherent in the above known lines.

The main objective of the inventive ore grinding line is to increase productivity while reducing the specific energy consumption of the ore grinding line with a self-grinding or semi-self-grinding head mill, as well as reducing capital and operating costs.

The technical result obtained by solving the problem lies in the creation of variable hardware and technological schemes for the ore grinding line, which can increase the line productivity while reducing specific energy consumption, as well as reduce capital and operating costs.

The ore grinding line is patented in options.

In all embodiments of the implementation of the line for grinding ores, the technical result is achieved by using ores for grinding in the second grinding stage for the overburning product (gali) of the head mill of self-or semi-grinding as a grinding apparatus of a drum-roller mill, which is due to its higher technological and economic efficiency compared to with ball mill.

In all embodiments of the implementation of the line for grinding ores, the technical result is also achieved by the fact that the use of a drum-roller mill eliminates the need for additional installation of a crushing apparatus, for example, a cone crusher, for preliminary refinement of gali (or a large fraction of gali) before grinding, since in this case drum-roller mill quite effectively performs both the function of the crusher and the function of the mill.

The advantages of the proposed options for ore grinding lines are the possibility of implementing many options for classification schemes and directions of movement of the products of mills of different stages of grinding, as a newly built or modernized enterprise has the technical ability to work most technically and economically rationally on any option on an ongoing basis or different options in separate production periods, for example, when changing the properties and characteristics of the ore entering the processing, or when changing the composition of the ore charge, or changing the production and technological tasks presented to the ore grinding line, such as, for example, reducing or increasing the fineness of ore grinding, reducing or eliminating sludge during grinding, decreasing or increasing the productivity of the line.

Due to the fact that in all variants of the implementation of the line for grinding ores in the second stage of grinding the super-mill product (gali) of the self-grinding or semi-self-grinding head mill, a drum-roller mill is used, the specific energy consumption of the ore grinding line is reduced, and the capital and operating costs are reduced, due to the following design features of drum-roller mills:

- specific power consumption reduced by 25-40%, compared with ball mills;

- high (about 70%) product yield after the first passage of the material through the mill;

- lack of grinding bodies (balls);

- a significant reduction in wear of the lining of the drum and roll;

- the ability to work both in “wet” and in “dry” modes;

- high maintainability;

- lack of effect of regrinding;

- controlled grinding process;

- compactness.

Also, due to the fact that in all embodiments of the ore grinding line in the second stage, a drum-roll mill is used that simultaneously uses the principles of crushing to grind the super-mill product (gal) of the self-or semi-self-grinding head mill, which is characterized by a relatively high resistance to ball grinding, and grinding material, and characterized by a high content of the finished class of fineness in its product, the newly built or modernized enterprise appears those It is possible to more significantly increase the performance of mills of the first grinding stage by increasing the size of the slit of the discharge grill of self-grinding or semi-self-grinding mills and, accordingly, increasing the output of critical material from the mill without additional installation of a crushing device, for example a cone crusher, for preliminary refinement of galium (or large fractions of gali) before grinding, which, in turn, leads to a decrease in specific energy consumption, as well as capital and operating routine costs.
