A tubular screen is concentrically mounted in a hollow journal of an ore discharging outlet of a horizontal grid type ball mill, an ore discharging overflow box is disposed below the tubular screen and connected with a sand pump tank, the sand pump tank is connected with an inlet of a first swirler through a sand pump, a bottom outlet of the swirler is connected with an ore feeding inlet of the grid type ball mill, and accordingly an ore grinding closed loop is formed. A closed-loop conveying belt for conveying coarse particles on the tubular screen to the ore feeding inlet of the grid type ball mill is mounted on the grid type ball mill, and another ore grinding closed loop is formed. Overflow of the swirler is conveyed to a second sand pump tank. The grid type ball miller of the ore grinding system is modified, so that the grid type ball miller forms a sectional mill, stable closed-loop ore grinding graded operation is achieved, effect is increased by above 50%, equipment potential is fully released, production cost is reduced, material grinding range of the grid type ball mill is widened, and the ore grinding system is capable of realizing treatment of various copper smelting slags including converter slag, flash furnace slag, accidental slag and the like.
Description
Technical field
The utility model belongs to the ore-dressing practice technical field, is specifically related to a kind of grinding system that uses grate ball mill processing copper smelting slag and improve ball milling board effect.
Background technology
What present domestic processing copper smelting slag grinding process adopted is: the production technology in semi-autogenous mill (a section)+ball mill (two sections) closed circuit grinding classification loop.Semi-autogenous mill utilizes steel ball and ore self to carry out ore grinding as milling medium as one section grinding machine, and characteristics are that flow process is short, and disposal ability is big.And if grate ball mill is as one section grinding machine, it is undesirable to handle the copper smelting slag ability, and there is a large amount of grate ball mills in present domestic ore dressing plant, purchases semi-autogenous mill again and handles copper smelting slag, not only the cost height also can cause the idle waste of grate ball mill.
Summary of the invention
The purpose of this utility model is at the primary grinding system, provides a kind of platform that can improve to imitate, cut down the consumption of energy, and can reduce the grinding system of the processing copper smelting slag of cost input again.
For achieving the above object, the technical scheme taked of the utility model is:
A kind of grinding system of handling copper smelting slag, one drum sieve is installed in the gape hollow axle journal of horizontal grate ball mill with one heart, under the drum sieve sieve ore discharge spill box is set, the ore discharge spill box connects the sand pump pond, the sand pump pond connects the inlet of one section cyclone by sand pump, the outlet at bottom of cyclone is connected with the feed port of grate ball mill, and it is closed circuit to constitute an ore grinding; Grate ball mill is equipped with goes up the closed circuit conveyer belt that coarse granule is delivered to the feed port of grate ball mill with the drum sieve sieve, and it is closed circuit to constitute another ore grinding; Two sections sand pump ponds are delivered in the overflow of one section cyclone.
Described drum sieve central authorities are provided with the porous spray header, and the flushing ore pulp is accelerated hierarchical speed.
The forward and backward water pipe of described grate ball mill is installed flowmeter, utilizes valve accurately to add water, the effluent concentration of stability ball grinding machine.
Install and scrape the ore deposit device at the cylinder place of described closed circuit conveyer belt, is used to clean the binding material on the belt conveyor.
The grinding system of the above-mentioned processing copper smelting slag that the utility model provides, grate ball mill is transformed, make it become one section grinding machine, and realized stable closed circuit grinding classification operation, and handle copper smelting slag platform effect and improved relatively more than 50%, can handle various copper smelting slags such as vessel slag, flash slag, accident slag, enlarged the scope of grate ball mill grinding material, and fully excavated equipment potential, and prolong old cycle equipment life, reduce production costs.Is example with common 2700*3600 grate ball mill transformation as handling one section grinding machine of copper smelting slag, the ball milling board is imitated and has been brought up to more than 18 t/h from 11t/h, increases output 63.6%, and not only the technological process of production is unimpeded, technical indicator is stable, remarkable in economical benefits.

Among the figure: 1-grate ball mill; 2-drum sieve; 3-ore discharge spill box; 4-sand pump pond; 5-sand pump; 6-one section cyclone; 7-closed circuit conveyer belt; 8-frequency converter; 9-water pipe; 10-flowmeter; 11-valve; 12-spray header; 13-two sections sand pump ponds; 14-cylinder; 15-scrape the ore deposit device.
The specific embodiment
Below in conjunction with accompanying drawing technical solutions of the utility model are further elaborated.
As shown in Figure 1 and Figure 2, a drum sieve 2 is installed with one heart in the gape hollow axle journal of horizontal grate ball mill 1, drum sieve 2 central authorities are provided with porous spray header 12, in order to the flushing ore pulp, accelerate hierarchical speed.Under drum sieve 2 sieves ore discharge spill box 3 is set, ore discharge spill box 3 connects sand pump pond 4, and sand pump pond 4 is by the inlet of one section cyclone 6 of sand pump 5 connections, and the outlet at bottom of one section cyclone 6 is connected with the feed port of grate ball mill 1, and it is closed circuit to constitute an ore grinding.Grate ball mill 1 is equipped with the closed circuit conveyer belt 7 of coarse granule on the sieve of drum sieve 2 being delivered to the feed port of grate ball mill 1, it is closed circuit to constitute another ore grinding, closed circuit conveyer belt 7 is by frequency converter 8 speed governing, when imitating with the copper smelting slag that adapts to different specific weight, different grinding machine platform to the requirement of belt speed, install and scrape ore deposit device 15 at stem motorized pulleys 14 places of closed circuit conveyer belt 7, scrape ore deposit device 15 and must contact by the circumference entity, be used to clean the binding material on the conveyer belt with cylinder 14.The forward and backward water pipe 9 of grate ball mill 1 is installed flowmeter 10, accurately adds water by valve 11, thereby has guaranteed when heightening the platform effect effluent concentration of stability ball grinding machine.
The course of work of the grinding system of the processing copper smelting slag that the utility model provides is:
Is example with common 2700*3600 grate ball mill as handling one section grinding machine of copper smelting slag, with the ore particle degree≤+ copper smelting slag of 25mm delivers to grate ball mill 1 and carries out ore grinding, the ore pulp that is flowed out by the grate checkerwork cell of grate ball mill 1 is after drum sieve 2 is crossed sieve classifications, the coarse granule disintegrating slag is discharged grate ball mill 1 by the guiding spiral on the sieve, returns grate ball mill 1 through closed circuit conveyer belt 7 and regrinds; The merging of the ore discharge of fine grained disintegrating slag and grate ball mill 1 is pooled to sand pump pond 4 under the sieve, raise through sand pump 5 and to deliver to one section cyclone 6 and carry out classification, the sand setting of one section cyclone 6 is delivered to grate ball mill 1 and is regrinded, and two sections sand pump ponds 13 are delivered in the overflow of one section cyclone 6, enter secondary grinding.
