Ore yard management system
In order to strengthen the management of the ore entering the raw material workshop, improve the homogenization effect of the ore, stabilize the quality of the ore, reduce the inaccurate batching caused by the fluctuation of the ore quality, and affect the next process index.
I. Acceptance procedures and acceptance contents of the incoming ore
1 The miners must be sorted according to the ore's ore and color classification.
2 For ore with more mud and roots, it must be piled up separately and should not be used without approval from the workshop.
3 The ore with obviously too much water can be stacked outside the shed according to the weather conditions to avoid and reduce the amount of refined lime used by the broken ore.
4 For the phenomenon of not unloading the car in accordance with the regulations, you can temporarily do not sign the receipt, and promptly respond to the workshop director.
5 The ore block exceeds the standard and must be indicated on the acceptance form and reported to the workshop at the first time.
6 Vehicles that place brake water in the site should be registered and indicated on the acceptance form.
7 The acceptance of ore is the primary work of the handover class. The shifting personnel must explain to the successor the mine collection situation. The successor must understand and understand the mining situation of the previous class, and supervise whether the previous class receives the ore according to the regulations. And record it. (If there is no ore entering the class, it is necessary to check the ore of the previous class, and truthfully transfer and hand over to the next class).
Second, the management of ore storage
1 All existing ore must be strictly listed. Content: mine point, weight, date, license plate number.
2 As the initial matching ore, it is stacked separately, used according to the workshop instructions, and may not be used without the consent of the workshop.
Third, the management of the initial allocation of ore
In order to ensure the initial distribution and homogenization of the grinding ore reaches A/S=8-10, according to the monthly mining volume of 15,000 tons (during the two groups), the ore reserves must reach:
1 The ore is A/S ≥ 9 and the quality is stable. The daily reserves are not less than 1000 tons. Use cloth car cloth.
2 The ore A/S fluctuates greatly. In order to reduce and stabilize the ore A/S, the ore is initially matched: the total amount of ore per month A/S ≥ 12 is not less than 3,600 tons, not less than 120 per day. Tons, as an adjustment to the initial allocation of ore. The total amount of ore with 7 ≤ A / S ≤ 8 per month cannot be higher than 4500 tons. If the mine is higher than 4500 tons/month or A / S is too low, if the above requirements are not met, the amount of ore with A/S ≥ 12 Should be increased.
The ore is equipped with the following:
Al 2 O 3 % SiO 2 % A/S
The first mine A 1 S 1 K 1
Second mine A 2 S 2 K 2
To be a mixed mine with A/S K, set the first mine to be 1 ton, and the second mine should be equipped with X tons, X = (A 1 - KS 1 ) / (K 2 S 2 - A 2 )
3 Before the ore is broken, the driver of the loading truck must carry out the crushing in strict accordance with the requirements of the workshop for the matching of the piles.
Fourth, the management of ore homogenization
1 After the crushed ore enters the homogenization warehouse, the fabric trolley must be opened to achieve further homogenization.
V. Requirements for homogenizing ore mining
1 In the primary selection of ore, in order to reduce the cost, the alkali consumption caused by silica in the ore is reduced as much as possible, and the artificially paid stone (not limited to personnel and posts) is used, and the compensation is 50 yuan/ton.
2 Before loading the truck, the mine must be in accordance with the requirements of the post personnel.
3 The loader must be mined according to the requirements of vertical reclaiming.
Six, assessment requirements
1 In order to ensure the initial ore and broken daily work tasks, the schedule of work and rest: 8:30 am - 12:00 am; 13:00 - 16:20 pm, during the work, without the consent of the workshop, the driver and other departments And personnel can not leave the post and privately mobilize the loading car for its use.
2 In order to save energy and reduce consumption, maintain the continuity of work, no special reasons (needing, cleaning, belt adjustment, maintenance needs) belt mining can not run empty (empty belt running 10 minutes), regarded as empty vehicle operation.
The 350-loader is a white-shift mine with a minimum of 7 hours of work per day. The time adjustment for all maintenance work must be based on the workload.
4 The ore is piled up and the mine is cleared to keep the passage smooth. It is necessary to cooperate with the miners to complete the night shift of the 50 loading vehicles. The main task is to work on the mine cost class according to the requirements of the miners.
5 In order to ensure daily mining tasks, a special loading vehicle must be assigned.
6 It is not allowed to use the fine lime to break the mine without the approval of the workshop.
7 The ore acceptance work must be carried out in strict accordance with the acceptance procedures and acceptance contents of the incoming ore.
8 Work must be carried out in strict accordance with the requirements of ore storage management, ore initial allocation management, ore homogenization management, and homogenization of ore mining.
In violation of the above provisions, the deduction of 20 yuan / time.
EDAWELD Co., Ltd. professional produce Laser products,laser nozzles,laser tips. We main produce two kinds of laser products, TRUMPF Nozzle and MAZAK Nozzle. The form and size of the nozzle nozzle selection of great influence on the cutting quality,There are three main forms of nozzle: parallel, convergent and cone form. Our laser nozzles are made by imported high-quality copper and use superb CNC technology. So they got bright surface and cutting speed, less wear and tear, as compared with the original parts, we can reach 90%. But our low prices, it is worth buying.
