It is the new impeller developed by Yixing Zeus Pump Co., Ltd. according to the actual working conditions and technical requirements of the hydrometallurgy industry and users. Its main features are corrosion resistance, wear resistance, temperature resistance (Less than 100 ℃). After several high-temperature leaching posts in domestic zinc smelters, the stirring effect, wear resistance, corrosion resistance and service life have reached very satisfactory results. Compared with the traditional precious metal alloy paddle Ratio, there is a clear cost advantage, the Inner Mongolia Xing'an copper and zinc smelting companies and other customers and industry experts evaluate that: the mixing paddle for the hydrometallurgical industry in the replacement of precious metal paddle products for wet-process smelting decay wear Stirring paddle structure features: combined 1. Blades for steel outsourcing ultra-high molecular weight polyethylene structure. 2. Leaves can be distorted according to user needs. 3. Paddle, wheels are all anti-corrosion wear structure. First, the wet-process corrosion-resistant wear-resistant stirring paddle technical characteristics and advantages: 1.1. The structure of the product The basic structure of the stirring paddle to the metal skeleton (including paddles, blades and hubs), over-current parts wrapped anticorrosive wear plastic layer, especially the paddles, wrapping the wear resistance is superior to the change UHMWPE, therefore, the impeller has both the high temperature resistance and impact resistance of steel, as well as the anticorrosion and abrasion resistance of the plastic, the paddle and the hub part, and adopts the multi-layer metal corrosion protection material The composite anti-corrosion structure, the performance is very reliable. 1.2. Anticorrosion and abrasion resistance of paddle material Advantages: The blade has excellent corrosion resistance due to the use of modified ultra-high molecular weight polyethylene material. In the hot-acid leaching process using the yellow-alum method for zinc hydrometallurgy , Some of the section of the slurry temperature up to 95 ℃, and in turn contains a certain amount of chloride and fluoride ions (chloride chloride 700 ~ 800 mg / L, fluoride ions about 100 mg / liter), this condition on the precious metal stirring paddle For leaf, it is very corrosive, so the service life of metal stirring blades such as stainless steel is not long, because of this. The ultra-high molecular weight polyethylene stirring paddle, just to overcome the shortcomings of the existing technology, to prevent corrosion of chloride and fluoride ions, to extend the life of the blade. The advantages of ultra-high molecular weight polyethylene stirring paddle lie in excellent abrasion resistance. The field test of the slurry pump for wet-process smelting shows that when the slurry temperature is 75-80 ℃, the weight ratio of liquid to solid is 1: 1 Slurry used, 500 million molecular weight modified UHMWPE material, wear-resistant than stainless steel 5 to 7 times. This is also evidenced by the use of ultra-high molecular weight polyethylene agitators in some zinc smelters in Inner Mongolia: 1800mm diameter paddles, m / s speed, running at 90 ° C for 6 months in zinc smelting leach slurry, See obvious wear and tear. Ultra-high molecular weight polyethylene unique advantages, to extend the service life of wear-resistant mixing paddle, laid the material foundation. 1.3. Hydraulic Properties of Ultra-high Molecular Weight Corrosion-Resistant Stirred Paddle Paddle blades can be non-twisted and twisted (ie, fan-shaped) according to user's specific requirements, which can help with the hydraulics of mixing. Users Practice has proved that the stirring blade distortion performance, to better meet the needs of zinc smelting process. 1.4. Corrosion-resistant wear-resistant paddle other advantages anti-plot thick, impact resistance. For advice, please call contact: Tan Xiping
