NTB-1000 SMOOTH ROLLER MILL

The Natreb Smooth Roller Mills, also called rolling mills or roll crushers, are widely used in pre-grinding, pre-grinding and finishing of fine particles with dry and wet materials. They can be used in the processing of mineral and vegetable coal, claystones, feldspars, clays, bauxites, limestones, graphites, ferroalloys, among other materials, both in mining and in the recycling, chemical and fertilizer industries. Its function is based on crushing the materials under compression between its two smooth, high-resistance cylinders, which can be developed in different steel alloys, depending on the application. The grinding of the particles is caused by the high pressure of the cylinders, generating microcracks in the larger particles, and thus leading to the generation of a large amount of fine material. Its production capacity is related to its size (model) and the regulation of the gap between the rollers.

• Monobloc type housing in welded sheet steel to meet the maximum operating condition that allows working without vibration.
• Cylinders with different speeds that rub the clay particles together, improving the lamination result.
• Spherical roller bearings sealed in their housings with a mechanical labyrinth system.
• Safety fuses and cylinder adjustment system totally external to the protections to facilitate periodic regulation.
• Conical bushing system for dismantling the pulleys.
• Support structure of the laminator suitable for receiving grinding. (Grinding is an optional equipment).
• Activation of the scraper blades by means of a electropneumatic system.
• High torque multi-V belt transmission.
• Spring cylinder damping system.
• Special alloyed steel shafts.
• Cylinder opening adjustment.

Produção varia conforme abertura entre cilindros e densidade. Densidade considerada do material 1,8 t/m³. Abertura mínima 1,0mm entre cilindros.
