Abstract
The present invention relates to the method dynamic ball adding methods that a kind of semi-autogenous mill rationally adds steel ball, its main feature is that under the premise of the suitable ore milling concentration of the grinding particle size and setting that keep requiring, according to the situation of change of the parameters such as the specification of semi-autogenous mill, rotational speed rate, mine-supplying quantity, pack completeness, running power, quantity of return mines, mog, it is dynamically determined suitable adding ball amount and adding ball time, so that semi-autogenous mill load pack completeness is maintained in appropriate range, while semi-autogenous mill mine-supplying quantity being made to reach the range of requirement.This method makes semi-autogenous mill working condition dynamically be maintained in optimum range always, to reach the minimum consumption of unit steel ball, unit liner steel consumption and ore grinding unit power consumption, production capacity also can be improved, reduce product granularity or improve recovery rate in ore-dressing.
Description
Technical field
The present invention relates to one kind to use for metalliferous mineral, industrial mineral, chemical industry mineral, energy source mineral and building materials material grinding
The replenishment method of powder grinding medium steel ball in semi-autogenous mill.
Background technology
Semi-autogenous mill be metalliferous mineral, industrial mineral, chemical industry mineral, can be important in source mineral and building materials materiel machining powder
Equipment is ground, the part for functioning as powder grinding medium of steel ball makes up the deficiency of massive ore media capabilities.In grinding process
Middle steel ball constantly wears and consumes, so needing constantly to add steel ball with the propulsion of grinding process, so as to protect in semi-autogenous mill
Hold necessary steel ball amount.Traditional steel ball method of adding is to be evenly distributed to the worn steel ball consumption that long-time statistical obtains often
The steel ball of identical quantity is added in a working day or class, daily or per tour.The shortcomings that this ball feeding method is that ball adding amount does not meet mine
Worn steel ball amount caused by stone change of properties and steel ball changes in material changes, therefore frequently results in the larger change of steel ball pack completeness
Change, further results in fluctuation and the consumption of unit steel ball, the unit liner steel consumption and unit power consumption of product granularity and production capacity
Raising.
Invention content
Exist to solve the problems, such as that tradition adds steel ball method, it is dynamic that the present invention proposes a kind of semi-autogenous mill ball feeding method-
State ball adding method.
The technical solution adopted by the present invention to solve the technical problems is：According to the specification of semi-autogenous mill, rotational speed rate, give mine
The variation of the parameters such as amount, pack completeness, running power, quantity of return mines, mog, when dynamically determining adding ball quantity and adding ball
Between, so that steel ball number keeps dynamic equilibrium in semi-autogenous mill.
The beneficial effects of the invention are as follows：By implementing above-mentioned technical proposal, semi-autogenous mill load pack completeness is made to be maintained at suitable
In the range of, while semi-autogenous mill mine-supplying quantity being made to be maintained in the range of requirement, to make semi-autogenous mill working condition always
It is maintained in optimum range, reaches the minimum consumption of unit steel ball, unit liner steel consumption and ore grinding unit power consumption, life also can be improved
Production capacity power reduces product granularity or improves recovery rate in ore-dressing.
Embodiment
A kind of semi-autogenous mill ball feeding method embodiment of the present invention, certain iron ore mine Ф 10.36m × 5.49m semi-autogenous mills require production
Ability is 930t/h, and product granularity ranging from 0.075mm accounts for 85%~90%.It is investigated through production, suitable steel ball pack completeness is 9%
± 0.5%, semi-autogenous mill running power is within the scope of 8300~9500kW, and for quantity of return mines within the scope of 120~180t/h, ore grinding is dense
Degree is 83%~84%.
Before semi-autogenous mill starts, semi-autogenous mill internal loading is drawn off, steel ball quality therein is measured, pack completeness is scaled and is equal to
8.5%, it is less than 9%.Supplement steel ball makes pack completeness reach 9%.Load is reinstalled into semi-autogenous mill.Start.
Start semi-autogenous mill, production capacity is adjusted to 930t/h, ore milling concentration is adjusted to 83%~84%；Measure product grain
Degree is that 0.075mm accounts for 87.5%, meets the requirement that 0.075mm accounts for 85%~90%；Semi-autogenous mill running power is observed, is
9200kW, quantity of return mines 160t/h are Appropriate.Continuous running, and semi-autogenous mill running power and quantity of return mines are observed at any time.
Observation finds that semi-autogenous mill running power gradually increases, and starts to add steel ball when more than 9500kW, adds 4t every time,
5min is added once.With the addition of steel ball, running power is gradually reduced, and stops adding steel ball when dropping below 8300kW.
It remains in operation, after a period of time, observation finds that quantity of return mines gradually increases, starts to add steel when more than 180t/h
Ball, adds 4t every time, and 5min is added once.With the addition of steel ball, quantity of return mines gradually decreases, and stops when being reduced to less than 120t/h
Only add steel ball.
Continue to add steel ball according to above method during long-term production.Statistical result shows in the life for ensureing to require
Under the premise of production capacity power, compared with traditional timing, quantitatively adding the method for steel ball, the consumption of semi-autogenous mill unit steel ball reduces about
20%, unit power consumption declines 15% or so, and mog improves 1~2 percentage point, and the magnetic separation roughing rate of recovery improves 1~2 percentage
Point.
