The working principle and structural features of the disc granulator
2020-07-02
The disc granulator is a new type of inclined-disc granulation equipment: its granulation rate can reach over 95%. The reducer and motor are driven by a flexible belt, which ensures smooth startup, reduces the impact force on the buffer, and significantly extends the equipment's service life. The bottom of the disc is reinforced with multiple radial steel plates, making it robust, durable, and resistant to deformation, thickening, or weight increase—while also featuring a sturdy base design. Notably, the machine operates stably without requiring anchor bolts. Additionally, the main gear of the granulator undergoes high-frequency quenching treatment, further enhancing its longevity. The anti-corrosion treatment applied inside the granulation disc is long-lasting. As a result, this machine delivers uniform granulation, boasts a high balling rate, operates smoothly and reliably, and boasts exceptional durability.

Refractory Materials and Performance Requirements for Side-Blown Furnaces
2020-06-22
The side-blown furnace is rectangular and consists primarily of a furnace bottom, furnace shell, hearth, furnace body, and furnace roof. Inside the furnace body are spray guns and a molten pool area, while the exterior is encased in a robust steel shell reinforced by water-cooled jackets. The interior is lined with refractory materials, which directly endure exposure to high-temperature slag, molten lead, and intense combustion flames. Consequently, the service life of these refractory materials directly determines the overall lifespan of the reduction furnace.
On the Manufacturing Technology of Smelting Furnaces
2020-06-16
The furnace bottom, furnace body, furnace roof, and outlet flue of the smelting furnace are equipped with cooling water jackets, and a layer of refractory bricks is laid on the furnace bottom. The smelting furnace has relatively high fuel consumption, but the waste heat boiler can recover most of the waste heat.
A Brief Discussion on the Features of Lead Extraction Pumps
2020-06-10
Due to the specialized maintenance required for lead tanks, as well as frequent leaks and emergency rescues, lead plating manufacturers must drain all the molten lead. Typically, this process is done manually by pouring the lead directly from the lead pot, which demands significant physical effort and results in extremely high labor intensity—tasks that most people simply cannot endure. However, when KND series lead pumps are used to extract the zinc liquid, their minimum flow rate of 30 tons per hour allows for pumping 100 tons of lead in just 3 hours. Not only does this dramatically reduce the time needed, but it also significantly boosts production efficiency. Moreover, it frees workers from grueling manual labor, greatly easing their physical burden. Additionally, using these pumps eliminates the risks associated with high temperatures and prevents molten lead from splashing onto personnel, further enhancing safety and improving the overall lead-plating process.
Applications and Maintenance of Lead Pumps
2020-06-05
Application scope of lead pumps: Designed for high-temperature lead liquid transfer in industrial environments, such as transporting lead liquid in multi-metal integrated recovery projects, and conveying alloyed lead liquid during the smelting process of lead alloys.
2020-05-26
The design of the lead pump takes into account numerous factors, such as the high temperature of molten lead, its significant density, and its tendency to solidify easily. Proper usage of the lead pump will ensure its long-term reliability. The operational steps for using the lead pump are as follows:
The working principle of a lead pump
2020-05-26
The lead pump primarily uses the centrifugal force generated by a high-speed rotating impeller to discharge molten lead. The key difference between a lead pump and a conventional centrifugal pump lies in their working media; their specific functions are as follows.

A detailed introduction to Henan's crude lead disc casting machine?
2020-01-03
If the auxiliary equipment for the coarse lead disc casting machine is to complete electroplating according to process requirements, simply having a power supply and plating tank isn’t enough—it also needs proper ancillary devices essential for smooth electroplating. This naturally includes heating or cooling systems, as well as equipment for cathode movement, agitation mechanisms, plating solution circulation, or even filtration units.
