According to the price network of Jintou 2021May 28th, the domestic recycling price of waste products includes: the lowest price of heavy waste products in Jiangsu, Zhejiang and Shanghai is 2,970 yuan, and the highest price is 3 120 yuan; In Jiangyin, Jiangsu, the lowest is 3 100 yuan, and the highest is 3250 yuan; In Taizhou, Zhejiang, the lowest is 3050 yuan, and the highest is 3250 yuan.
Matters needing attention in scrap recycling:
1, the recovered scrap steel sometimes needs to be cleaned. Scrap steel is used to remove oil, rust, sediment and so on from the surface of steel parts by various chemical solvents or hot surfactants. Often used to deal with a large number of engines, bearings, gears and so on. Contaminated by cutting oil, grease, oil stains or other attachments.
2. Scrap steel is often mixed with waste aluminum, copper and scrap iron in the recycling process, so it must be carefully distinguished when recycling. The distinguishing method is as follows:
A, you can use a magnet to attract. If aluminum, iron and copper are mixed together to make mixed metal powder, the purity is relatively high. At this time, the iron can be easily separated with a magnet, and then the iron can be dried with a hair dryer. By controlling the wind, density can be used for separation.
B, can make use of the magnetic differences of various substances in solid waste, a treatment method of sorting in uneven magnetic sound. Magnetic separation is an effective method to separate iron metals.
After the solid waste is input into the magnetic separator, the magnetic particles are magnetized under the action of non-uniform magnetic sound, thus being attracted by the magnetic field, so that the magnetic particles are sucked into the cylinder and discharged with the cylinder at the discharge end; Due to the small magnetic field force, non-magnetic particles remain in the waste. Usually, the magnetic field source used in magnetic separation is electromagnet or permanent magnet.
