Henan Sankuang Machinery, Precision Manufacturing Base of Polyurethane Wear-Resistant Rollers, Full-
The polyurethane roller production line of Henan Sankuang Machinery Technology Co., Ltd. finished delivery of wear-resistant flotation roller orders, which will be shipped to mineral processing lines in Peru and Iran. We built an integrated production line covering metal roller core precision machining and polyurethane casting, equipped with CNC lathes, cylindrical grinders, constant-temperature casting equipment and vulcanization lines. The machining precision of metal roller cores reaches micron level; polyurethane coating has uniform thickness without bubbles or delamination, with wear and acid-alkali resistance meeting global export standards, widely applied in rice mills, flotation machines and conveyor equipment.
Complete inspection procedures are carried out for every roller: full inspection of metal cores, precise coating thickness measurement, hardness test, abrasion resistance test and medium corrosion resistance experiment. Roller core material reports and polyurethane physical performance test sheets are attached to each finished roller. To meet overseas import standards, we allow independent third-party inspection on roller dimension, Shore hardness, abrasion loss and bonding strength, with compliant test reports issued to satisfy acceptance specifications of mining equipment imports in all countries.
Supported by complete metal precision machining equipment and mature polyurethane casting technology, our wear-resistant rollers are exported to Russia, Bulgaria, Southeast Asia, South America and Europe all year round. Custom rollers with customized hardness, diameter and length are available. Independent machining of metal cores guarantees coaxiality. Dual quality guarantee from full-process inspection and authorized third-party testing makes us a stable roller supplier for overseas mineral processing and grain manufacturing enterprises.
