Fill the water tank of the truck at home in advance, weigh it with a weighbridge under the witness of the staff, and then drive to the warehouse to load the garbage. During driving, start the button to pour out all the water in the water tank. Then, after being filled with waste, they return to the weighing company for weighing. The staff recorded the two times of weighing, and the difference of weighing was the weight of garbage, and then settled according to the price.

The disposal method of scrap steel varies with the material and shape. Fragile and irregular bulk materials are broken with a heavy hammer. Cut the super-thick and super-long large scrap steel into qualified sizes with a flame cutter. Larger scrap iron blocks were crushed by blasting. Thick waste steel plates, sections and bars are sheared by shears.
Lightweight materials with small volume and low specific gravity, such as scrap chips, scrap steel wires, waste car shells, etc., are pressed into blocks by balers and used as steelmaking raw materials after bundling.
The leftover material produced by cutting is degreased and pressed by a press. Scrap steel mixed with other metals is first crushed and then separated by magnetic separation. In recent years, a new crushing technology with liquid nitrogen at -50 ~- 100℃ has been developed. However, the separation of scrap steel from nonferrous metals and other impurities has not been completely solved. The use of mixed scrap steel should be limited to a certain proportion so as not to affect the quality of steel.
