A powdered organic fertilizer production line, custom-built for a client in Lhasa, has recently passed factory inspections and high-altitude adaptation modifications; the equipment has been loaded onto three trucks for shipment to Lhasa. The production line comprises a chain crusher, rotary screener machine, double shaft paddle mixer, automatic packaging scale, and dust removal system, with a designed hourly capacity of 3 tons.

To address the specific conditions of Lhasa—including an altitude of 3,650 meters, low atmospheric pressure, and significant diurnal temperature fluctuations—the technical department implemented several adjustments: main motors were re-selected based on high-altitude derating factors and equipped with increased cooling airflow; electrical control cabinet components were configured with increased creepage distances and automatic temperature-controlled heaters to ensure reliable startup at -15°C; conveyor belts were made from cold-resistant, UV-resistant materials; and anti-aging agents were added to exposed rubber parts. During the trial run, the entire line operated continuously for four hours in a simulated low-pressure environment, with crushing fineness and mixing uniformity meeting all contractual specifications.

For the packaging and transport phase, crusher hammers were removed and boxed separately; mixer inlets and outlets were sealed after the interior was cleaned; and the electrical control cabinet was fitted with desiccants and component reinforcements. The equipment was secured using steel cradles and anti-slip pads, with high-strength straps anchoring the loads to the truck beds. The transport route follows the Qinghai-Tibet Highway; the logistics department has verified height restrictions and road conditions along the way, and escort personnel have been assigned to accompany the shipment.

Documentation accompanying the goods—including installation drawings, operation manuals, electrical schematics, and high-altitude usage guidelines—has been sealed in waterproof bags. The three trucks have now departed the factory and are en route to Lhasa as planned.
