Honesty as the foundation, quality as the key to success

Zhengzhou Chenrui Machinery Equipment Co., Ltd. is an enterprise integrating, manufacturing and sales. Our products have passed CE certification and quality certification. The company's products are applied in various industries such as plastics, rubber, electronics,metals, and textiles.Our company mainly produces various types of single-shaft shredders,double-shaft shredders, tire shredders, metal crushers, plastic crushers,Solid waste shredder, copper and aluminum shredders, and,non-ferrous metal crushing and sorting equipment, as well as completesets of environmental protection production lines. These devices are widely used in the recycling and processing of waste materials and the recycling and utilization of renewable resources.The company's technical engineers, based on the actual situation, optimize and combine various types of equipment to meet different process requirements of customers (equipped with sorting machines, dustremoval equipment, etc.); it has the advantages of high crushing efficiency, low energy consumption, low noise and easy maintenance. lt has been widely recognized in domestic and foreign markets.Our equipment has been exported to countries and regions such as Canada, Spain, Mexico, Zambia, lvory Coast, Algeria, Japan, South Korea, the Philippines, Turkey, ltaly, Vietnam, Australia, Malaysia, Sin-gapore, India, the United States, Saudi Arabia and Dubai.

Quality is the core foundation of our industrial crushing, shredding, and non-ferrous metal sorting equipment. As a professional manufacturer dedicated to solid waste recycling and mineral processing machinery, we implement a full-process, standardized, and traceable quality control system covering raw material procurement, processing, assembly, factory testing, and after-sales delivery. We strictly adhere to international manufacturing standards to ensure every shredder, crusher, and metal separation production line delivers stable performance, high durability, and maximum operational efficiency for global clients.

1. Strict Raw Material Incoming Inspection

The durability and operational stability of crushing and sorting equipment depend entirely on high-quality raw materials. We maintain long-term cooperation with qualified certified suppliers. All core raw materials, including wear-resistant alloy steel plates, high-strength steel frames, motor components, and precision bearings, are strictly inspected before warehousing.

Unqualified raw materials and accessories are completely rejected to eliminate potential quality risks from the source, ensuring the wear resistance, impact resistance, and structural stability of machine bodies, crushing rotors, cutters, and sorting core parts.

2. In-Production Process Quality Supervision

We implement standardized quality management for every processing and production procedure. Each production link, including precision machining, welding, and surface treatment, is supervised by dedicated quality inspectors.

For key components such as shredder blades, crusher hammers, vibrating screens, and sorting magnetic separation systems, we conduct real-time monitoring of machining tolerance, welding quality, and heat treatment effects. Regular calibration of production and testing equipment is performed to guarantee consistent component accuracy, minimize processing errors, and ensure the interchangeability and assembly precision of all parts. Every process record is archived to achieve full production traceability.

3. Finished Product Comprehensive Testing

After complete assembly, all standalone machines and production lines undergo strict standardized factory testing.  conditions to test the equipment’s crushing efficiency, material adaptability, wear resistance, and continuous operation stability. For metal sorting equipment, we conduct targeted sorting rate and purification tests for copper, aluminum, and other non-ferrous metals to Only products that pass all test items can be marked qualified and enter the delivery process.

4. Standardized Finished Product Inspection 

Before delivery, our QC team conducts a final full inspection of equipment appearance, structural integrity, accessory completeness, and parameter configuration. We strictly classify and control product defects with clear acceptance criteria to ensuring customers receive intact and high-quality equipment.

5. Continuous Quality Optimization & After-Sales Guarantee

We regard quality improvement as a long-term sustainable work. We collect equipment operation feedback from global customers, combine actual working condition scenarios of waste recycling, mineral processing, and metal separation, continuously optimize production processes and product structure, and upgrade product performance and durability.

In addition to strict pre-sales quality control, we provide standardized after-sales quality assurance services, including installation guidance, operational training, regular maintenance reminders, and after-sales troubleshooting, ensuring stable long-term operation of our equipment and creating lasting value for customers.

Adhering to the principle of "Quality First, Customer Oriented", we rely on rigorous quality control standards to manufacture reliable industrial crushing and sorting equipment, helping global users reduce failure rates, improve production efficiency, and lower operating costs.
