Nickel ore sintering machine
It involves two aspects:
-
the company does not transfer out the medical insurance card, but continues to pay for you: you can't transfer out personally, so you need to transfer out from the company
-
the company did not transfer out the medical insurance card, and did not continue to pay, so that the medical insurance card is in arrears: take your personal identity and bank card, and you can transfer out after paying your arrears The medical insurance center involves the operation of several departments, and the specific departments have to be asked on site. I remember when I did it, I went to the director of medical insurance to issue certificates, to the finance department to pay, and then to the window office to transfer out.)
and is operated by an unknown private company,
it is easy to manipulate the price and cause losses to investors,
it is possible for the operation platform to run away or close down
suppose that we can proce 1200 tons of sinter 24 hours a day
1. The daily output of 1200 tons of new rectangular sintering machine is about 6 million yuan without environmental protection equipment, and the investment of traditional sintering machine is about 5.5-12 million yuan
2. The installed capacity of the traditional sintering machine is about 3100kwh (charged desting), while that of the new sintering machine is 1600kwh. Assuming that the electricity charge is 0.6 yuan, it can save 20000 yuan per day
3. If the air volume of traditional sintering machine is 6000 cubic meters per minute, and that of new sintering machine is 2000 cubic meters per minute, about 2 million yuan investment will be saved in electrostatic precipitator and bag filter
4. The consumption of coal powder of traditional sintering machine is as high as 10% per ton of sinter, while the consumption of coal powder of new sintering machine is about 5%. Only for this, the sintering machine can save 60 tons of coal powder, equivalent to RMB 60000 per day
5. The traditional sintering machine needs to use gas for ignition. The sintering machine with a daily output of 1200 tons of sinter needs about 9000 yuan of gas per day, while the new sintering machine does not use gas
6. In terms of scalability, e to the small amount of flue gas, the new sintering machine will not be put into operation again in the future
comprehensive analysis shows that the application of the new sintering machine can increase the annual income of the enterprise by more than 20 million e to its energy saving in gas, coal and electricity.
Sintering machine is not a machine, but a project composed of several processes. Take the 48 square meter laterite nickel ore sintering machine project of Jinye Metallurgical Equipment Manufacturing Co., Ltd. as an example:
the main process of sintering machine is composed of the following parts:
quicklime crushing room, coal (coke) powder crushing room, batching warehouse, primary mixer room, secondary mixer room, 70m2 sintering machine room Binder, heat breaker, screening chamber, etc
batching warehouse
raw material warehouse (60) × Two 50 type loaders and one 5 * 8m sliding screen are set for drying and screening of raw ore mixed lime. They are used as the reserve material storehouse for sinter proction. There are six silos in the storehouse. The ore powder and fuel are proportioned by electronic scale and flux by screw feeder according to the set proportion and then sent to the mixer room by the main proportioning belt
mixing room
mixing room φ two point two × Two 9m mixers are used to add water to a certain humidity and mix the incoming materials well. In the second mixture, the mixture is pelletized and the mixture is heated
sintering chamber
the mixture is evenly distributed in the mixing bin along the length direction by shuttle distributor, and then the mixture is evenly distributed on the 1.5m wide sintering plate by the combination of round roller distributor and multi roller distributor, and then it is fed into the igniter along with the rotation of the plate. The mixture preheated by hot air is heated and ignited by the burning high temperature flue gas. Under the action of negative pressure ventilation, the mixture burns downward with the trolley moving forward, and the physical and chemical changes are completed at the tail of the machine, and the hot sinter is fired φ one point five × 2.0 m single roll crushing falls into the screening system
quick lime crushing chamber
the large pieces of quick lime passing the inspection are sieved to & lt; 3mm> 85% of the lime powder is sent into the flux bin, weighed and digested before batching
coal (coke) powder crushing chamber; 3mm> 85% of the fuel powder is sent into the fuel bin, and then weighed and fed to participate in the batching<

1. The daily output of 1200 tons of new type rectangular sintering machine is about 6 million yuan without environmental protection equipment, and the investment of traditional sintering machine is about 5.5-12 million yuan
2. The installed capacity of the traditional sintering machine is about 3100kwh (charged desting), while that of the new sintering machine is 1600kwh. Assuming that the electricity charge is 0.6 yuan, it can save 20000 yuan per day
3. If the air volume of traditional sintering machine is 6000 cubic meters per minute, and that of new sintering machine is 2000 cubic meters per minute, about 2 million yuan investment will be saved in electrostatic precipitator and bag filter
4. The consumption of coal powder of traditional sintering machine is as high as 10% per ton of sinter, while the consumption of coal powder of new sintering machine is about 5%. Only for this, the sintering machine can save 60 tons of coal powder, equivalent to RMB 60000 per day
