During roller compaction, the powder is compressed by two counter rotating rollers. The material is fed into the rollers with feed screws and they also help to increase the density of the powder before the compaction stage. A compacted drug forms as a result of mechanical interlocking and intermolecular forces.

A road roller is used primarily for compacting soil, gravel, asphalt, and concrete during the construction and maintenance of roads and pavements. To use a road roller, position it at the starting point of the area to be compacted, ensuring the surface is free of debris. Operate the machine by engaging its controls to move forward and backward, applying weight and vibration as necessary to achieve optimal compaction. Finally, overlap each pass slightly to ensure even coverage and consistency in the compacted surface.
This industry covers establishments primarily engaged in manufacturing ball and roller bearings (including ball or roller bearing pillow block, flange, takeup cartridge, and hangar units) and parts.

Roller marks in glass are caused by the manufacturing process, specifically during the glass forming stage. As molten glass is shaped and cooled between rollers, any imperfections or discrepancies in the roller surfaces can leave marks on the glass. These marks can be influenced by factors such as temperature, pressure, and the speed of the rollers. Proper maintenance of the rollers and careful control of the production conditions can help minimize these imperfections.
