In a roller pump, a section of flexible tubing is mounted against a rigid outer support, as shown in Figure II.5.5.15.The rollers compress a section of tubing, preventing backflow, and pushing the blood forwards. The flow from a roller pump is pulsatile, which can have a beneficial effect on mass transfer, and if the rollers occlude the tubing completely the flow rate is dependent on the speed ...The rollers are not powered and use gravity, if inclined, to move the product, or manually if mounted horizontally. The conveyors can be straight or curved depending on the application and available floor space. Powered Roller. Powered Roller Conveyors use powered rollers mounted in frames to convey products.

Drive Rollers and Idler Rollers Information. Drive rollers and idler rollers are cylindrically-shaped material handling components that convey items through a machine, process, or environment. They deliver time, space, and energy efficiencies in resource handling applications. Drive rollers rotate via direct interaction with a motor.The theories behind these machines are very simple, heat an air space up, and then tumble the material to be dried through this space until it is dried. All though it sounds simple there are problems that have to be solved before the required results are met. But first, so you know what we are talking about lets go through the design of a drier.

During a metal rolling operation, the geometric shape of the work is changed but its volume remains essentially the same. The roll zone is the area over which the rolls act on the material, it is here that plastic deformation of the work occurs.Operating principle Four to eight card or draw frame slivers are fed to the drafting arrangement (3). A feed roller pair (2) is located above each can (1) to enable the feeding step to be performed in a controlled manner without false drafts. The feed roller pairs are mounted in a creel frame or table and each is positively driven.

The Basic Principles of Roller Burnishing. Fig. 1: Material flow. The main goal of roller burnishing is to achieve high-quality smooth surfaces or surfaces with pre-defined surface finish. One or more rollers or balls plastify and deform the workpiece's surface layer. This process is used when the goal is to either achieve a high-quality ...Dry granulator sub-classes are primarily distinguished by the densification force application mechanism and they include; 1. Slugging. 2. Roller compaction. 1. Slugging. In slugging, a large tablet (slug) is produced in a heavy-duty tableting press. This mechanism of dry granulation leads to variation in the weight of one slug to another.
