Description
Technical field
The utility model belongs to metal ore dressing technical field, and in particular to a kind of equipment is reliable, dramatically increases grinding machine processing
The system of amount and energy-saving continuous removal semi-autogenous mill abrasion steel ball.
Background technique
Ore grinding is metal, the necessary procedure in non-metal mine dressing plant, and usual ore presses certain grain after broken
Grade proportion feeds grinding machine autogenous grinding, reaches feed particle size after ore grinding and just can enter and sorts process.So ore grinding is for sorting operation work
Prepare, energy-efficient and qualified granularity clean material, quality and the ore grinding effect of ore mill discharge are provided for ore-dressing practice
Rate directly affects technique of preparing economic indicator.Autogenous tumbling mill be will the raw ore from stope or the ore Jing Guo coarse crushing etc. directly to
Enter, be medium using grinding charge material itself, is realized and crushed by mutual impact and ablation.And semi-autogenous mill is in autogenous grinding
A small amount of steel ball is added in machine, to improve its ore grinding processing capacity and reduce energy consumption.Semi-autogenous mill grinds mineral in rotation
In the process, the mutual impact and collision between steel ball, inevitably will lead to it and becomes smaller or partial crushing, become smaller and fragmentation
Steel ball does not have the abrasive action to mineral not only, but also can accelerate the abrasion of normal steel ball, and mixed broken ball in ore pulp
Enter lower end technique or equipment in the case where sorting is not added, will cause the blocking to ore-dressing technique pipeline, especially sand pump is made
The abrasion of Cheng Geng great causes accessory loss fast, and sand pump shuts down replacement accessory and influences equipment availability, leverages production stream
The patency and mineral processing production of journey.In addition, usually raw ore enters semi-autogenous mill ore grinding after coarse crushing, the ore pulp after ore grinding is through dividing
Grade, particulate ore pulp feed normal mill and select process, and coarse grain mine or coarse grain ore pulp are back to semi-autogenous mill and regrind and recycle.Due to
The abrasion steel ball for becoming smaller and being crushed in the ore pulp of semi-autogenous mill ore discharge containing part, and wear most of granularity+40 of steel ball
Mm or more, since part wears ball hardness is high, after being recycled inside with coarse grain mine or coarse grain ore pulp return semi-autogenous mill easily
Hard rock is formed in inside, occupies mill volume, to reduce grinding capacity and increase the energy consumption and steel consumption of ore grinding, increases cost.
Aiming at the problem that wearing steel ball occupancy mill volume, generally taking intermittent outage, all taking-up steel ball and remaining mine screen divide doing for removal
Method, mill mineral loss when not only resulting in shutdown, support staff be more, larger workload, security risk are difficult to eliminate, and clear
Mill volume still can be occupied before reason, causes grinding capacity lower, also there is also increase ore grinding energy consumption and steel ball loss.
" much broken and lessmill " is that energy-saving effective ways are generally acknowledged in ore dressing circle both at home and abroad at present, how simply and effectively to be improved
The grinding capacity of semi-autogenous mill and the loss for reducing steel ball, have great importance to reduce ore grinding energy consumption.
Utility model content
The purpose of this utility model is to provide a kind of equipment reliably, dramatically increases grinding machine treating capacity and energy-saving company
The system of continuous removal semi-autogenous mill abrasion steel ball.
Purpose of the utility model is realized as follows: including semi-autogenous mill, double-deck screen shale shaker, rough conveying unit, steel
Ball conveyer, the discharge gate of the semi-autogenous mill are set to above the feed end I of double-deck screen shale shaker, under the double-deck screen shale shaker
The sieve lower discharge port of layer sieve selects the feeding channel of flow sheet equipment to connect with normal mill, the lower screen of the double-deck screen shale shaker
Sieve top discharge mouth I is set to the top of feed end II of rough conveying unit, the exhaust end of the rough conveying unit with it is Semi-Autogenous
The feeding inlet of machine connects, and the sieve top discharge mouth II of the upper screen of the double-deck screen shale shaker is set to the feed end of Steel ball conveyor
III top.
The utility model has the advantages that compared with prior art
1, the utility model is stupid with easily being formed in inside after coarse grain mine or coarse grain ore pulp return circulation according to abrasion steel ball
The problem of stone occupies mill volume, and grinding capacity is caused to reduce and increase ore grinding energy consumption and steel ball loss, using double-deck screen shale shaker
It sorts, in time can divide automatically the steel ball worn in semi-autogenous mill under not shutdown status instead of conventional single-deck vibrating screen
From, so that will not form hard rock in semi-autogenous mill occupies mill volume, the grinding capacity of semi-autogenous mill can be dramatically increased, and
When the separation that decreases the loss of steel ball in semi-autogenous mill, and wear steel ball of separation abrasion steel ball be only vibration assorting room
In subsidiary function, do not increase additional energy consumption, whole energy consumption reduction is more significant.
2, the utility model avoids abrasion steel ball half by just removing the abrasion steel ball that ore pulp contains in Semi-Autogenous process
It is worn away repeatedly in autogenous tumbling mill and enters the normal mill of ore pulp inflow and select process, not only ensure that the purity and quality of ore pulp, but also
It is avoided that normal mill selects the blocking of process pipe and causes bigger abrasion to sand pump, to improve the serviceability rate of equipment, it is ensured that
The patency of production procedure and ore dressing normally produce, and increase economic efficiency.
3, the utility model replaces conventional single-deck vibrating screen that abrasion steel ball can be realized using mature double-deck screen shale shaker
Continuous separation, not only equipment is relatively simple reliable, nor can destroy existing equipment layout；The continuous separation of mechanization is not
Operating personnel can be only reduced, reduces labor intensity and process cost, moreover it is possible to eliminate safe hidden trouble.
Therefore, the utility model has the characteristics that equipment is reliable, can dramatically increase grinding machine treating capacity and energy-saving.
