Product Features

Rapid & Uniform Heating

Dual-sided heating above and below the roller table ensures uniform temperature distribution.
Heating zones can be finely controlled to maintain minimal top-bottom deviation (≤5°C).
High-efficiency SiC or MoSi₂ elements ensure reliable performance at high temperatures.

Energy-Saving Structure

Roller kilns require no kiln cars or saggers; only refractory backing plates are needed.
Reduced heat loss leads to energy savings and lower operating costs.

Transmission System

Equipped with a precision helical gear mechanism, minimizing transmission deviation.
Features include small footprint, high torque, smooth startup, and reliable motion.

Full Automation Ready

Independent control cabinet integrates temperature, roller speed, and alarms.
Optional touch screen + PLC interface supports data logging, auto-start, and remote monitoring.
Roller movement and heating profile are programmable for batch or continuous production.

Modular and Custom Design

Designed per customer’s process parameters: sintered material, temperature, and throughput.
GWDL engineers provide tailored solutions, balancing thermal uniformity, environmental protection, and automation.
