One, enterprise technical accumulation: 25 years focused on tile-making equipment research and development

Zhengzhou Xinlong Machinery Manufacturing Co., Ltd. was established in 2001, with a factory covering an area of approximately 30,000 square meters and 25 years of experience in the production of roof tile equipment. As one of the earlier companies in China to engage in the cement colored tile machine field, its technical team has, through continuous iteration, formed a comprehensive technological capability covering equipment design, mold development, and automatic control. For instance, its core equipment is made of high-strength alloy steel, with a mold life exceeding 100,000 times, suitable for producing colored cement tiles with thicknesses of 4-6mm and widths of 300-440mm, meeting the building specification requirements of different regions.

Section 2: Technical Principle: Closed-loop Control from Raw Materials to Finished Products

The production of colored cement tiles involves four major processes: raw material proportioning, mixing and blending, high-pressure molding, and natural curing. Xinlong Machinery achieves precise parameter control through PLC control systems: raw material proportioning errors are kept within ±1%, mixing time is dynamically adjusted based on material fluidity (usually 8-12 minutes), molding pressure is stabilized between 25-30MPa, ensuring tile density reaches 2.1-2.3g/cm³. The natural curing stage employs segmented temperature control technology, maintaining humidity above 85% and temperature at 25±2℃ for the first 3 days, and gradually reducing to room temperature over the next 4 days, enhancing the tile's flexural strength to over 18MPa.

Section 3: Equipment Advantages: Modular Design and Overseas Adaptability

In response to diverse market demands, Xinlong Machinery offers two types of equipment: the Standard Model (output of 800 pieces per hour) and the High-Speed Model (output of 1200 pieces per hour). The Standard Model has a total power of 38kW and occupies an area of 15㎡, suitable for domestic small and medium-sized production lines; the High-Speed Model features a dual-position molding structure with a total power of 55kW, catering to the needs of overseas large-scale projects. The equipment supports customization, such as the moisture-proof mold developed for Southeast Asian customers, which maintains over 95% impermeability in regions with an annual rainfall of 2000mm by adding drainage channels.

Four, Typical Case: Technical Upgrade Project of a Building Materials Factory in Hebei

In 2022, Xinlong Machinery provided a complete transformation plan for a color cement tile production line for a building materials factory in Hebei. The original equipment used traditional hydraulic molding, which had issues such as high energy consumption (0.12 degrees of electricity per tile) and high scrap rate (about 8%). After the transformation, servo motor driving technology was adopted, reducing the energy consumption per tile to 0.08 degrees and controlling the scrap rate within 2%. Within the first 6 months of the project's operation, the customer's new order volume increased by 40%, and the products were exported to Mongolia, with a single batch export reaching 500,000 tiles.

V. Technical FAQ: Common Questions Explained

Q1: What are the requirements for raw materials in the cement colored tile machine?
A: Use 42.5 grade ordinary silicate cement, fine modulus of 2.3-3.0 medium sand, and gravel with particle size below 5mm. The raw material mud content must be less than 3%, otherwise it will affect the tile strength.
Q2: How is the equipment maintenance cycle arranged?
A: It is recommended to check the hydraulic system oil level every 200 hours, change the reducer lubricating oil every 500 hours, and polish the mold every 1000 hours to extend the service life of the equipment.
Q3: How to solve the tile surface bubble issue?
A: Solutions can be achieved through a combination of adjusting the stirring speed (recommended 15-20 rotations per minute), adding a vacuum degassing step (vacuum level -0.08MPa), and extending the standing time (5-8 minutes).

Six, Technological Outlook: Dual Drive of Intelligence and Greening

Xinlong Machinery is developing an Internet of Things-based remote monitoring system. By installing sensors at critical parts of the equipment, it collects real-time data such as temperature, pressure, and vibration to achieve fault early warning and production optimization. At the same time, its new generation equipment adopts waste heat recovery technology, using the heat generated during maintenance for raw material preheating, thereby reducing comprehensive energy consumption by 15%, meeting the carbon peak goal requirements of the building materials industry.
