Zhicheng Screen Mesh cooperates with a certain sandstone field in Chengdu

A sand and gravel yard supplies the surrounding construction market. Due to the higher quality requirements for sand and gravel in the construction industry and the tightening of environmental protection policies, problems frequently occur in its traditional screening process and equipment. Ordinary screens wear out quickly when screening high-strength sand and gravel. The shutdown due to screen replacement lasts for 3 - 5 days per month, affecting production. Moreover, the screening accuracy is poor. The granularity of finished sand and gravel is uneven and the mud content exceeds the standard, making it difficult to meet the needs of high-end projects and limiting market competitiveness and expansion. With its reputation, technology and diverse products, Zhicheng Screen reached cooperation with the sand and gravel yard after investigation, inspection and communication.

(1) Preliminary investigation and scheme customization The two parties established a joint investigation team, including technical experts from Zhicheng and key personnel from the sand and gravel yard. They went deep into the site to monitor the characteristics of sand and gravel raw materials (hardness, humidity, particle size distribution, etc.) and record the operating parameters of the production line (vibration frequency, etc.) to accurately identify pain points. Zhicheng customizes a fine screening scheme according to the data and designs a multi-level and differentiated pore size screen combination for different sand and gravel products. For example, large-pore manganese steel screens are used for coarse aggregates of concrete, and high-precision polyurethane screens with a pore size of 0.15 - 2 mm are used for fine sand for bricklaying and plastering. 

(2) Equipment installation and debugging Zhicheng organizes a professional team to install according to the scheme and operates strictly in accordance with the process to ensure seamless connection and accurate installation of the screen and upstream and downstream equipment. After installation, Zhicheng and the employees of the sand and gravel yard cooperate in debugging. According to the production situation, parameters such as screen vibration, pore size and flow rate are fine-tuned. After multiple rounds of trial production, the stable and efficient operation of the system is guaranteed. 

(3) Personnel training and technical support Zhicheng organizes a one-week training for the employees of the sand and gravel yard, including principles, structures, operation specifications, troubleshooting and handling. The combination of theory and practice improves skills. For subsequent cooperation, long-term technical support is provided. There is a customer service hotline for answering questions. Technical personnel are regularly sent for return visits to provide optimization suggestions according to needs and changes in raw materials.

(1) Significantly improved production efficiency The new screen is durable. The frequency of screen replacement is greatly reduced. The shutdown time is reduced from 3 - 5 days per month to once every 1 - 2 months. The sand and gravel processing capacity is increased by 30% - 40%. Precise screening makes the flow of sand and gravel smooth, reduces rework and blockage, and improves overall efficiency. 

(2) Excellent product quality The uniformity of the granularity of finished sand and gravel is improved. The classification accuracy exceeds 95%. The sand and gravel used for concrete and bricklaying and plastering meet the standards, improving quality indicators. The mud content is reduced from 8% - 10% to less than 3%, winning favor in the high-end market. 

(3) Substantial economic growth With excellent product quality, the price per ton is increased by 10 - 15 yuan. Orders and market share increase. The sales volume in half a year increases by 30% - 40%. The production efficiency is increased and the maintenance cost is reduced. The comprehensive cost is reduced by about 20% - 25%, with strong profitability. 

(4) Prominent environmental benefits Precise screening reduces unqualified sand and gravel waste and reduces pollution. The new screen has low energy consumption and helps the sand and gravel yard establish a good image. In conclusion, the cooperation between the two parties has achieved fruitful results and provided a reference for the development of the industry.
