  • What is ingot mold
    What is ingot mold

    An ingot mold is a container or mold used in the casting process to shape and solidify molten metal into ingots. It is typically made of durable materials such as cast iron, steel, or graphite, and is designed to withstand the high temperatures and pressures involved in the casting process.

    Working Principle of Eddy Current Sorter

    Eddy current sorting is a sorting technique that utilizes different conductivity of materials. Its sorting principle is based on two important physical phenomena: an alternating magnetic field that changes over time is always accompanied by an alternating electric field (electromagnetic induction law); A current carrying conductor generates a magnetic field (Biot Savart's law).

  • Smelting and classification of lead
    Smelting and classification of lead

    01. Lead smelting The main raw materials for lead smelting are lead sulfide concentrate and a small amount of block ore. There are two methods for smelting lead: pyrometallurgy and wet metallurgy. Currently, pyrometallurgy is the main method in the world, and wet metallurgy of lead is still in the experimental research stage. The pyrometallurgical lead smelting process basically adopts the sintering roasting blast furnace smelting process, accounting for 85-90% of the total lead production; Next is the reaction melting method, which can be equipped with chamber furnaces, short kilns, electric furnaces, or vortex furnaces; Precipitation melting is rarely used. The refining of lead mainly adopts fire refining, followed by electrolytic refining, but due to customary reasons, electrolytic refining is not widely used in China. For difficult to separate sulfide lead zinc mixed concentrates, the closed blast furnace smelting method that simultaneously produces lead and zinc is generally used for processing. For the extremely difficult to separate mixed ore of lead and zinc oxide, a unique treatment method has been developed in China through long-term research, which involves using the raw ore or its enriched products of the mixed ore of lead and zinc oxide, sintering or pelletizing them, and melting them in a blast furnace to obtain coarse lead and molten slag containing lead and zinc. The slag is further fumigated in a fuming furnace to obtain zinc oxide products, and electrolytic zinc is obtained through wet zinc smelting. In addition, zinc oxide products can also be directly fumigated using a rotary kiln.

  • Battery dismantling machines
    Battery dismantling machines

    Battery dismantling machines Battery dismantling machines (battery dismantling machines, battery dismantling machines) easily disassemble waste batteries. If electric vehicle batteries and car batteries are directly disposed of, they pose a significant risk and require centralized recycling for harmless treatment. Therefore, we will use our company's waste battery dismantling machine. The battery car battery dismantling machine equipment uses manual feeding to push waste batteries into the body. The propulsion system pushes the batteries into the position to be cut, and the crank drives the cutting blade to accurately cut off the waste battery cover. The cutting blade can be adjusted, and the propulsion system pushes the next battery forward again.

  • Customized 10T rotary furnace for our clients
    Customized 10T rotary furnace for our clients

    Rotary smelting furnace A rotary furnace is a type of blast furnace, whose body is an inclined cylindrical container that can rotate. The principle of rotary furnace is to use the effect of high temperature and high-speed Redox to mix ore and coke together, rapidly heat and melt in the furnace, and separate metal and waste slag. The internal parts of the rotary furnace are divided into different areas, with the top layer being the combustion zone, where coke and oxygen react to produce high-temperature and high-pressure gas flow. The gas flows downwards and enters the reduction zone. The ore and coke undergo a reduction reaction in the reduction zone, and the metal is reduced out. The metal flows downwards along the furnace barrel and finally reaches the slag area, where it is separated from the waste slag. The rotary furnace has the advantages of high production capacity and high melting efficiency, and can melt various metal materials such as iron, steel, and alloys. In the steel industry, rotary furnaces have become one of the main steelmaking equipment, widely used in fields such as steelmaking, ironmaking, and scrap recovery. Lead scraps, Lead grid, Lead acid battery scrap, adaptable to different raw materials. The Lead melting rotary furnace consists of a rotary host, a fire-resistant furnace lining, a combustion system, a hydraulic system, a Ring gear transmission system and a flue system. Both charging and discharging pass through the furnace mouth installed with a furnace door. During charging and discharging, the furnace door installed with a burner can be opened. Auxiliary machines are equipped with supporting automatic feeding machine, automatic slag (soup) bag and slag raking machine, and automatic ingot casting and stacking machine. Through these supporting equipment, the automatic operation of the whole process can be realized. Details include: - Refractory Material of Chrome-Magnesium basis - air-fuel burner or Oxy-fuel burner or Heavy oil burner - Feeding door opening through local control panel and through remote control - Door operation system with hydraulic unit; - Rotation system 0 - 1 rpm with variable speed driver (by VFD)
