Abstract
The invention discloses a kind of multistage milling systems, the ball milling unit including at least two groups in tandem, and every group of ball milling unit includes at least two table grinders, and the ball mill of adjacent ball mill group is connected in parallel by ore slurry pipeline, are designed with solenoid valve on each ore slurry pipeline；It further include the control system with solenoid valve electrical connection.Every group of ball milling unit is connected by ore slurry pipeline in the present invention, and solenoid valve is all set on every ore slurry pipeline, if there is ball mill to break down, the solenoid valve that the ore slurry pipeline connecting with failure ball mill is howled at a funeral can be closed by control system, stop the pulp conveying between other normal ball mills and failure ball mill, failure ball mill will not influence the normal operation of entire milling system；Pressure sensor is equipped in the present invention also in ore slurry pipeline, the discharge pressure in each ore slurry pipeline is monitored by pressure sensor to judge whether ball mill breaks down, staff is enable to understand fault message in time, is overhauled convenient for staff.
Description
Technical field
The present invention relates to mineral processing production technical field, especially a kind of multistage milling system.
Background technique
During the time in grinding production in dressing plant, needs to carry out multiple grinding operation, ore grinding is improved by multiple ore grinding
Yield and quality.And in existing multistage grinding system, once some ball mill breaks down, it will lead to entire ball milling system
System stops production, and needs to overhaul the ball mill of failure, seriously affects time in grinding production efficiency.
Summary of the invention
The technical problems to be solved by the present invention are: providing a kind of multistage milling system, single ball mill breaks down not
It will affect the work of whole system.
To solve above-mentioned technical problem the technical scheme adopted by the invention is that: multistage milling system, including at least two groups
Ball milling unit in tandem, every group of ball milling unit includes at least two table grinders, and the ball mill of adjacent ball mill group passes through mine
Slurry pipeline is connected in parallel, and is designed with solenoid valve on each ore slurry pipeline；It further include the control system with solenoid valve electrical connection.
Further, including three groups of ball milling units in tandem, respectively the first ball milling unit, the second ball milling unit
With third ball milling unit, every group of ball milling unit is made of three table grinders；Each ball mill of first ball milling unit passes through mine
Slurry pipeline is connect with each ball mill of the second ball milling unit；Each ball mill of second ball milling unit pass through ore slurry pipeline with
Each ball mill of third ball milling unit connects.
Further, being equipped with pressure sensor in the ore slurry pipeline, the pressure sensor and control system are electrical
Connection.
The beneficial effects of the present invention are: the present invention, by setting multiple groups ball milling unit, every group of ball milling unit passes through ore pulp pipe
Road connection, and is all arranged solenoid valve on every ore slurry pipeline, if there is ball mill to break down, can be closed by control system with
The solenoid valve that the ore slurry pipeline of failure ball mill connection is howled at a funeral, stops the ore pulp between other normal ball mills and failure ball mill
Conveying, failure ball mill will not influence the normal operation of entire milling system；Pressure is equipped in the present invention also in ore slurry pipeline
Sensor, monitors the discharge pressure in each ore slurry pipeline by pressure sensor to judge whether ball mill breaks down,
So that staff is understood fault message in time, is overhauled convenient for staff.
Detailed description of the invention
Fig. 1 is schematic diagram of the invention；
In the figure, it is marked as the first ball milling of 1- unit, the second ball milling of 2- unit, 3- third ball milling unit, 4- ball mill, 5- mine
Starch pipeline, 6- solenoid valve.
Specific embodiment
To facilitate the understanding of the present invention, the present invention is further detailed with reference to the accompanying drawing.
Such as Fig. 1, multistage milling system of the present invention includes the ball milling unit of at least two groups in tandem, every group of ball mill
Group includes at least two table grinders 4, and the ball mill 4 of adjacent ball mill group is connected in parallel by ore slurry pipeline 5, each ore slurry pipeline
Solenoid valve 6 is designed on 5；It further include the control system being electrically connected with solenoid valve 6.Cooperate solenoid valve 6 right by control system
Conveying between each solenoid valve 6 is controlled, when there is ball mill to break down, staff by control system close with
The solenoid valve 6 on ore slurry pipeline 5 that failure ball mill 4 connects, stop failure ball mill 4 and other normal operation ball mills 4 it
Between pulp conveying.In order to grasp the operating status of ball mill 4, it is designed with pressure sensor in every ore slurry pipeline 5, is led to
Over-voltage force snesor judges whether ball mill breaks down to monitor the discharge pressure in each ore slurry pipeline, makes staff
Fault message can be understood in time, overhauled convenient for staff.
Embodiment 1
As shown in Figure 1, the first ball milling unit 1, the second ball milling unit 2 and third ball milling unit 3 are in tandem, every group of ball milling
Unit includes three table grinders 4；Each ball mill 4 of first ball milling unit 1 passes through ore slurry pipeline 5 and the second ball milling unit 2
Each ball mill 4 connect；Each ball mill 4 of second ball milling unit 2 passes through ore slurry pipeline 5 and third ball milling unit 3
Each ball mill 4 connects；Solenoid valve 6 is designed on every ore slurry pipeline 5.
Multistage milling system of the present invention can guarantee the normal operation of whole system, will not occur because of certain table grinder
Failure and so that whole system is stopped production, grinding efficiency can be effectively improved.
