High-Precision Machining
Drum machining

304/316L/321 stainless steel, material welding and processing strictly follow the ASME system of the American Society of Mechanical Engineers, longitudinal/circumferential weld inspection rate ≥20% (radio/ultrasonic inspection), and penetrant flaw detection 100%. The drum surface is processed by a high-precision grinder with ultra-mirror treatment (Ra≤0.4 μm), co-axiality ≤0.05 mm, to ensure long-term 

Scraper System

The material is high-performance alloy (such as high-tin copper alloy, special stainless steel, etc.) or high-performance polymer material (resin, polyetheretherketone (PEEK), etc. Non-contact design, fixed gap between scraper and drum (0.05-0.3 mm) based on the required thickness of the desired flakes, manual or automatic adjustment of scraper angle and gap, supports fast fine-tuning (accuracy ±0.05 mm), and equipped with an intelligent material thickness gauge to monitor material slice thickness in real time.

Fully Enclosed Environment

Adopting an involute arc material tray and a fully enclosed body, the leakage of material sublimation is reduced by 40%. The body is equipped with a nitrogen or dehumidified gas instrument wind purge protection system to prevent the deterioration of oxidizable and moisture-absorbing materials.

Intelligent Control

Precise Control of Flake Thickness:

The drum is variable frequency speed regulation, and the rotation speed is adjustable within the range of 2-12 rpm. It can intelligently detect the slice thickness. If there is an abnormal slice thickness, a chain alarm will be issued, and then the slice thickness will be controlled by adjusting the speed and feed amount.

Precise Interlocking Control of Liquid Level:

The liquid level transmission system remotely monitors the liquid level in real time and interlocks with the pneumatic control valve at the feed port to control the liquid level. In addition, the liquid level control valve group, composed of multiple nozzles such as reflux, high overflow, and drain, equipped with a mechanical design, can also control the liquid level locally by mechanical means. When the liquid level reaches the height of the high overflow port, the material will return to the pipeline from the overflow port.

Discharge Temperature Control:

The discharge temperature is interlocked with the cooling system to monitor the discharge temperature in real time and adjust the cooling system flow according to the slice temperature to control the flake temperature intelligently.

System Temperature Control:

Our patented PLC automatic temperature control interlock ensures that the temperature fluctuation is ≤ 2℃, and the technical agreement and acceptance standards accept the highest temperature detection and cooling effect standard detection in various industries.
