High-Efficiency Dual-Layer Natural Gas Drying Oven for Cement Fiber Board & Calcium Silicate Board Production Line

This drying system integrates seamlessly into your existing board forming line. It typically follows the dewatering and pre-pressing stations and precedes the cutting, curing, and finishing sections. Our solution includes the drying oven本体, a high-efficiency low-NOX natural gas burner system, a heat circulation and exhaust unit, a PLC-based control cabinet with HMI, and a chain or roller conveyor system customized to your board size and weight.

Our dual-layer natural gas drying tunnel is engineered for the rapid and uniform removal of moisture from cement fiber boards and calcium silicate boards. It utilizes a two-pass design to maximize floor space efficiency. The system employs precisely controlled, high-temperature clean air (heated indirectly via heat exchangers) to ensure consistent board quality, prevent warping, and achieve the required physical strength before autoclaving.

Specifically designed for drying cement fiber boards, calcium silicate boards, and fiber cement siding after forming and pressing, to prepare them for the autoclave curing process.

We understand that every production line is unique. Our ovens can be fully customized in length, width, internal zone configuration, conveyor type (roller/chain), and heat distribution profiles to match your specific board formula, initial moisture content, and target production speed.

• Dual-Layer Design: Saves significant factory floor space while doubling throughput.
• Indirect Heating: Provides contaminant-free, clean hot air critical for product quality.
• Zoned Temperature Control: Allows for a tailored drying curve (heating, constant-rate, falling-rate stages) to optimize energy use and prevent defects.
• Energy Recovery: Optional heat recovery systems from exhaust to preheat intake air, reducing fuel consumption.

We offer turnkey project support, including installation supervision, commissioning, and operator training. Our service package includes a comprehensive warranty, 24/7 remote technical support, and readily available spare parts.

Major components are shipped in heavy-duty wooden crates for ocean freight. Electrical parts are packed in waterproof boxes. We handle all export documentation and can arrange CIF/FOB shipping per Incoterms.
