The second generation of low-speed granulators from Ningbo Beilun Rhong Machinery Manufacturing Co.,Ltd. comes in three upgraded models. They now have rings on the side bed cutter housing and the scraper housing that allow for tool-less opening of the unit in a single action with bare hands. The Model 200 has removed the casing of the crashing cutter, which which can eliminate mis-cuts. Model 300 has redesigned side housings that can open 138° for easier access to cleaning and maintenance. Other new features include two-sided blades for all the cutters and the scraper; a more durable small rotating blade; dust wiper and airpurge function to protect the bearing; and anti-vibration torque arm that extends the life of the bearing and reduction gear by 60%.
