Recently, by Jiangsu Zhongtai EcoTech Group Co., Ltd the zt 30 series dual-pressure dehydration equipment independently developed was successfully put into operation in the copper slag tailings treatment project of a large copper industry group in Hubei. This project is not a simple equipment replacement, but a technological revolution with 'nano-ceramic filtration + dual-pressure intelligent control' as the core. It has successfully reduced the tailings moisture content from 14% to 7%, increased the processing capacity by nearly 46%, and saved over six digits in annual transportation costs. It has set a new benchmark of 'high efficiency, energy saving, and cost reduction' for tailings dry discharge in the non-ferrous metal industry.
In the field of non-ferrous metal smelting, the dehydration treatment of copper slag tailings has always been a key link affecting the economic benefits of the enterprise. The Hubei Copper Group's original ordinary ceramics Filtration Machines have long faced the pain points of 'high moisture, low productivity, and high cost':
l The filtration accuracy of traditional equipment is insufficient, causing the moisture content of the filter cake to be as high as 14%, which seriously increases the burden of subsequent transportation and storage;
lThe existing equipment is not fully automated and needs to be manned on a 24-hour three-shift basis , which imposes a heavy labor cost burden.。
lThe processing capacity of 5 tons per hour is no longer able to meet the production line expansion needs, seriously restricting the company's cost reduction and efficiency improvement process.
In view of the material properties of copper slag tailings , which are 'high hardness, fine particle size, and difficult to dewater,' Zhongtai Environmental Protection customized the zt 30 series dual-pressure dehydration solution for the copper industry group . The core of the equipment uses the country's leading nano-ceramic filter media with a pore size accuracy of up to 0.15 microns. Together with the dual-pressure intelligent control system, it achieves the triple breakthrough of ' high-precision filtration + automated operation + low energy consumption output' .
The zt 30 series equipment put into operation this time has not only achieved a 'nano-level' upgrade of the filter media in terms of hardware, but also completed a leap from 'manual intervention' to 'intelligent control' in terms of control logic.
lThe core of the equipment is made of high-strength nano- scale ceramic filter plates, which are made through a special sintering process. The microporous structure on the surface is dense and uniform, which can effectively intercept more than 98% of copper slag particles while ensuring that the filtrate is clear for reuse.
lDual -pressure control technology monitors filtration resistance in real time through pressure sensors, automatically adjusts pressure difference and cleaning frequency to avoid filter plate clogging and ensures that the equipment is always in optimal operating condition.
lThe equipment integrates a PLC intelligent control system to realize 'one-click start and stop, automatic cleaning, and self-diagnosis of faults', reducing labor requirements from 24 hours and three shifts to 16 hours of unmanned duty.
Compared with the traditional dehydration process, Zhongtai Environmental Protection zt 30 series equipment has verified the value of technological upgrades with 'hard core' data. After the equipment is put into operation, the copper slag tailings treatment efficiency has been improved by leaps and bounds:
l The processing capacity per hour jumped from 5 tons to 11 tons, and the efficiency increased by nearly 46%, easily meeting the production line expansion needs;
lThe moisture content of the filter cake has been reduced from 14% to 7%, effectively reducing annual transportation costs;
l Running time is compressed by 33%, energy consumption and labor costs are significantly reduced, equipment stability is improved, and maintenance cycles are extended by more than 50%.
The successful application of the Hubei copper slag tailings project is not only a vivid practice of Jiangsu Zhongtai Environmental Protection's 'technology-driven, customer first' concept. In the future, Zhongtai Environmental Protection will continue to use technological innovation as the engine to deepen the research and development of core technologies such as nanoceramic filtration and intelligent control, expand application scenarios in metallurgy, chemical industry, mining and other fields, and provide more efficient, smarter and greener solid-liquid separation solutions to global industrial customers.
