This company has introduced a new, modular jar-rolling mill that can be provided with one to four tiers, each with two to five rollers. Modular construction permits the user to start with a small unit and then add more rollers or tiers as requirements increase. The 2-hp motor provides enough power to handle heavy jars and dense materials. The spacing between rollers can be adjusted to accommodate various-size jars. The rollers are made of heavy, steel cores covered with durable urethane for excellent traction and long wear.
