Recently, the author learned from the production site of No. 4 Plant of Shuikoushan Non-Ferrous Metals Group Co., Ltd.: In 2014, the plant achieved a total recovery rate of 95.17% for electric zinc smelting, 97.75% for fused smelting, and recovery of refined indium after excellent production tasks were completed. 73.72% and direct silver picking rate of 72.6% were all new historical records and created higher benefits for enterprises.
The company has taken many measures to improve the quality of products, production, smooth running rate of equipment, reduce energy consumption, material consumption as the core of the competition, the indicators will be decomposed step by step, the quantitative assessment of the workshop. The leaching workshop, electrolysis workshop, and smelting workshop are designed to reduce the total power consumption of zinc and improve the total recovery rate of zinc and the direct yield of fused cast. In the labor competition, it is combined with the excellent personal achievement of the squad, prompting operators to operate meticulously, and try to reduce The cost is significant. In 2014, total recovery rate of zinc smelting in the Shuikoushan zinc system and the straight rate of fused casting reached the highest level in history, and the total electricity consumption per ton of zinc was reduced by 30 kwh. In order to improve the recovery rate of refined indium, after controlling the extraction conditions in the thin and expensive workshop, the leaching process is required to control the acidity and temperature, so that indium-rich slag containing indium is leached into the solution as much as possible, achieving a new high 73.72% recovery rate of refined indium. In order to increase the direct yield of silver deposits and focus on solving the key issues affecting the cost and benefits, the filtration workshop will focus on strengthening a section of filter presses, control the level of pulp, eliminate leakage, and use the difference in the location of pharmaceutical additives to better exert pharmaceutical effects. The direct yield of silver picking was 72.6%, which is the best in history. (Li Xinghua)
it includings hookstrip Shaker Screen and Corrugated shaker screen.
1)
Hook strip shaker screens are applied most widely at present, Main feature as follows:
- These products screen panel are constructed with two or three 304 or 316 stainless steel wire cloth layers with a steel backing plate combined together. Because of different mesh size, and steel backing plate, on the condition of using intensity, to get the best and most effective filtering area.
- The above of thin wire cloth with middle and the bottom of the thick wire cloth, combined with different thickness steel backing plate together, infinitely enhance the whole screen use intensity. Because of different model and clients requirement, can choose different steel backing plate form, for example hexagonal, rectangular, square and so on, supporting the above different screen cloth, the whole cloth is divided into independent small surfaces, prevent the part excessive expansion damaged, better extend the use lifetime.
- it including models: Derrick FLC2000 PWP shaker screen, Derrick FLC500 Series PWP shaker screen, Derrick Hyperpool PWP shaker screen , Derrick 313 PWP shaker screen.
2) Corrugated shaker screen is named by its special corrugated form.Main feature as follows:
1. These products screen panels are constructed with two or three 304 or 316 stainless steel wire cloth layers, after compounded and bended, with a steel backing plate combined together. The wire cloth and bottom steel backing plate combined tightly, increase the filtering area 120% to 150% more than hookstrip flat screen, get an better effective
2. it including models:
- Derrick FLC2000 PMD shaker screen,
- Derrick FLC500 Series PMD shaker screen,
- Derrick Hyperpool PMD shaker screen ,
- Derrick DP600 Series shaker screen.
