Zhengchang provides an overview of the elements of a good feed project
Press release
According to Zhengchang, there are six elements to a good feed project: 1. Reasonable plant environmental planning; 2. Detailed quality standards for process equipment; 3. Strict engineering construction WBS node management and control; 4. International standard quality control system; 5. Continuous innovation of smart factories; 6. Stable and reliable equipment. More is explained in the article below.
1. Reasonable plant environmental planning
Reasonable plant planning is the first step of a good feed project.
From the site selection of the feed factory to the design of environmental protection and safety supervision, the functional division of the plant area must meet the requirements of the production process, fire protection and environmental protection, urban planning, and architectural geomancy.
For the problem of waste gas emissions from feed factories, it is necessary to conduct centralised cooling treatment for the dust odour discharged from the pulverizing pulse fan, the odour from the cooling fan, and the odour from the drying exhaust gas. Then the activated carbon purification treatment and ultraviolet photolysis waste gas purification treatment are required to achieve European and American emission standards.
In noise treatment, sound insulation and vibration isolation materials are used; mufflers are installed on the inlet and outlet pipe sections of the ventilator to control the noise radiated from the inlet and outlet.
The separation of rainwater from production and domestic sewage in feed plants, as well as the separation of production sewage and domestic sewage, should be planned and designed in advance, and separate sedimentation tanks should be set up to divert production waste-water and rainwater from office canteens to their respective settling tanks and then discharged.
2. Detailed design quality standards for feed production technology
Zhengchang's professional design team has a set of strict and detailed design quality standards from the factory's general plan, process plan, three-dimensional renderings, to three-dimensional engineering design. For each specific factory process design, Zhengchang will conduct accurate planning for the entrance of raw materials into the factory, storage, various types of warehouse groups, logistics line, batch mixing, crushing and granulating, finished product storage and distribution, oil storage and addition, boiler transformer, electrical control automation system, and for detailed, customised engineering to ensure the safety, efficiency, environmental protection, cleanliness and aesthetics of the factory.
Zhengchang strives for perfection in engineering details. The company focuses on wear-resistant measures of equipment and pipelines, noise treatment, airflow, dust and odour treatment, dust and explosion prevention, precision, and energy efficiency. Fast disposal of tailings and miscellaneous materials, equipment hoisting, start-up operation, human-machine safety, and ergonomic design, enable the majority of companies using Zhengchang equipment engineering to benefit from an environmentally-friendly, clean, and profitable feed factor
3. Rigorous feed process design quality standards
With strict engineering construction WBS node management and control, Zhengchang pays attention to the technical details of the feed plant engineering, and strives to make every section, every equipment, and every part measurable, so as to avoid waste and improve production quality.
Zhengchang feed project management and control has a total of 255 nodes, which comprehensively control the progress, safety and quality of project construction. The total duration of on-site construction is accurately controlled. Company leaders can understand the progress of the project in real time, and the safety and quality can be accurately determined in the first time Decision to resolve.
The project progress is reported daily to the working WPS node in the form of real scenes, and horizontal comparisons can also be made between various engineering projects. The achievement rate of each department of each project is displayed in the form of histogram, wave chart, and pie chart, which provides intuitive data basis for management and senior leadership, enabling timely project delivery.
4. International standard quality control system
Adhering to the concept that quality starts from design, Zhengchang says that their projects "completely eliminates design errors". Using international advanced design software, a modular, parametric design and quality control system and three-dimensional display model is clear at a glance at the design stage. The software can automatically generate engineering drawings, section drawings and non-standard prefabricated parts drawings to eliminate errors.
86 categories and 450 kinds of prefabricated parts currently adopt the three-dimensional standardised modular design. The standardised production and on-site assembly also greatly shortens the installation period and improves project quality.
5. Continuous innovation of smart factories
The development of feed engineering is inseparable from the innovation of intelligent factory areas. Zhengchang insists on intelligent logistics, warehouses, and production, and provides quality operation management services on this basis.
Some intelligent systems include: intelligent control system, scheduler, big data centralised control and processing, energy consumption and maintenance monitoring of production section; dust-free hydraulic grain unloading shed, automatic unpacking machine, positive pressure of powder into the bin are used for receiving raw materials, automatic de-ironing device for raw grain cleaning; in the crushing section, the crushing and feeding materials automatically discharges iron and stone, broken screen detection, automatic and continuous screen change, bearing temperature measurement, spark detection, vibration monitoring; batch mixing and automatic calibration scale, micro-scale system; automatic control of the granulator in the granulation cooling section, automatic oil injection of the granulator, automatic gap adjustment of the pressure roller, processing of the head of the granulator, water adjustment of the cooler. In addition, the technology of intelligent production workshop such as tailings processing brings unlimited possibilities for development.
6. Stable and reliable equipment
Stable and reliable equipment is the foundation of good feed engineering. Since its establishment in 1918, Zhengchang has experienced a century of vicissitudes and has always insisted on continuous innovation in products, from the first domestic pelletiser developed in the early stage to the largest domestic output (hourly production of 75t/h) 1208 granulator, from the wholly-owned acquisition of American CPM's investment in China's granulator factory in 1998 to the improvement of the core technology of CPM granulator. In terms of crusher equipment, Zhengchang has a number of patented technologies, among which "multi-cavity technology" increases the efficiency of the entire crusher by 30%.
For Zhengchang's double-shaft mixer, a result of the exclusive purchase of European 'Forberg' technology in China, the use of functions and technical content have reached an international advanced level. With the combination of Chinese and European technology, the transmission is more stable, and is the mixer that European feed companies see as an industry benchmark.
In summary, reasonable environmental planning of the plant area makes for a more stable start of a feed project; the meticulous processing of the quality control points of the feed production process brings more efficient production efficiency to the feed factory; the rigorous construction management and control of WBS node project has achieved the century-old quality plan of Zhengchang Project; the international standard quality system provides for a more competitive quality feed factory in the industry; the continuous innovation of intelligent factories brings more room for development to companies; stable and reliable equipment will provide a brighter production outlook for customers.
