The cover type roller jar mill is fitted with a protective cover over the moving rollers. It allows safe operation where dust release or operator contact must be avoided, and its synchronous belt drive transmits speed without slippage.

Key Features

Variable frequency, program-controlled stepless speed regulation
Integral rollers lined with a wear-resistant polyurethane sleeve — higher friction coefficient, the jar does not slip or deform
Feeding size below 3 mm (up to 10 mm for soft material), final fineness 20-300 mesh (65-75 µm)
Protective cover for special environments — reduces dust release and contact risk
Synchronous belt transmission — slip-free, repeatable speed transfer
Model options from one station up to eight stations
Universal wheels for easy moving, balancing feet for stable operation
