Description
Technical field
The invention belongs to the preparation equipment technical field, be specifically related to a kind of iron ore and mix rock rate on-line detecting system.
Background technology
The iron ore mine generally has two kinds to the technology that iron ore carries out preliminary election at present, a kind of is that iron ore preliminary election technology is located at the stope, be that iron ore is after the stope is through coarse crushing machine, middle disintegrating machine, crushed product carries out tailings discarding by preconcentration with the iron ore of dry-type magnetic extractor after to fragmentation, the weak magnetic mineral of selecting or ferromagnetism iron mineral are transported to the ore dressing plant to carry out carefully broken or ultra-fine broken, then the finished breaking product is sent into grinding-classification operation, the dry-type magnetic extractor mine tailing directly is transported to Pai Yanchang; Another kind is that iron ore preliminary election technology is arranged on the ore dressing plant, after promptly the iron ore of extraction being transported to the ore dressing plant from the stope, behind coarse crushing machine, middle disintegrating machine, middle disintegrating machine ore discharge carries out tailings discarding by preconcentration through dry-type magnetic extractor, weak magnetic mineral of selecting or strong magnet mineral are proceeded thin broken or ultra-fine broken again, then the finished breaking product is sent into grinding-classification operation, the mine tailing of dry-type magnetic extractor is transported to Pai Yanchang again.Foregoing dry-type magnetic extractor mine tailing amount is exactly to mix the rock rate with the number percent of selected amount, it is an important indicator in bargh's production management, the high production efficiency that can reduce crushing process of the mixed rock rate of ore, increase the transportation cost of ore, especially iron ore preliminary election technology is arranged on the bargh in ore dressing plant, the transportation cost of increase is very obvious.Mixing the rock rate and can be production management and bring great convenience so in time grasp ore, is the key link that realizes the production economical operation.
Summary of the invention
The purpose of this invention is to provide a kind of iron ore and mix rock rate on-line detecting system, realize that iron ore mixes the online detection and the demonstration of rock rate, can line balancing provide in time in order to adopt, transport, to select, active data supports, be one of guarantee of mine realization economical operation.
The objective of the invention is to realize by following technical proposals.
Iron ore of the present invention mixes rock rate on-line detecting system, it is characterized in that respectively going out mine mouth by being separately positioned on the stope, the haulage vehicle automatic identification equipment that the iron ore transportation is along the line, the computing machine that is provided with the mixed rock rate calculation procedure of iron ore that is connected with these haulage vehicle automatic identification equipments, the A/D converter that is connected of the input interface of computing machine therewith, what A/D converter was connected therewith is separately positioned on dry-type magnetic extractor to the mine tailing check weighting apparatus under dry separation check weighting apparatus under the barrow band and the dry-type magnetic extractor mine tailing belt, is connected with the output interface of described computing machine and the display that is located in the Production Scheduling System is formed.
Described dry separation check weighting apparatus, mine tailing check weighting apparatus are electronic scales or uclear scale.
The mixed rock rate on-line detecting system of iron ore of the present invention respectively goes out mine mouth in the stope, transportation key position along the line is provided with the haulage vehicle automatic identification equipment, and identification signal sent to computing machine, so that the ore source of identification haulage vehicle, when haulage vehicle was poured ore into disintegrating machine, just available following method was measured the mixed rock rate of this stope ore;
By being located at dry-type magnetic extractor to the dry separation check weighting apparatus under the barrow band (electronic scales or uclear scale or other check weighting apparatuses), the ore throughput of centering disintegrating machine ore discharge (being that dry-type magnetic extractor is given the ore deposit) detects;
By being located at the mine tailing check weighting apparatus (electronic scales or uclear scale or other check weighting apparatuses) under the dry-type magnetic extractor mine tailing belt, the rock throughput of dishing out is detected;
More than the signal of two weight somascopes insert computing machine through A/D converter, through calculating the mixed rock rate that just can obtain a certain stope extracted ore;
The mixed rock rate that calculates is sent to Production Scheduling System shows, make things convenient for the production scheduling personnel to grasp the ore situation of each stope, provide important evidence for instructing to produce.
The invention has the beneficial effects as follows: mix rock rate on-line detecting system by iron ore, can in time grasp the mixed rock rate situation of each stope, mining methods are selected by unit for mining, and reducing the mixed rock rate of ore provides foundation; For enterprise realizes the production economical operation, optimize and adopt, transport, select production management that important evidence is provided; Also can effectively reduce iron ore unit transport cost, improve disintegrating apparatus production efficiency, concerning the enterprise of iron ore mine, have huge economic benefit and social benefit.
