Black weighing.Literature describes a patented pneumatic pneumatic /pneu·mat·ic/ (noo-mat´ik) 1. pertaining to air. 2. respiratory. pneu·mat·ic adj. 1. Of or relating to air or other gases. 2. weighing system for carbon black. For many years it has been acknowledged that to minimize carbon black degradation in pneumatic conveying systems, the product must be handled slowly in a dense phase mode, according to according to prep. 1. As stated or indicated by; on the authority of: according to historians. 2. In keeping with: according to instructions. 3. the literature. This meant that, although pneumatically fed scales give many advantages in the mixing room, their use is limited due to the dilute phase velocities Phase velocity The velocity of propagation of a pure sine wave of infinite extent. In one dimension, for example, the form of the disturbance for such a wave is given by y(x, t) = A sin [2π(x/λ - t/T required to achieve accurate weighing. The company has developed a dense phase scale that is said to combine the advantages of pneumatic scales with those of slow motion conveying, while maintaining the accuracy required for quality assurance. The literature describes how the company tested two types of carbon black, N660 and N234, using the dense phase weighing technique with a 30 m long NB100 conveying line. Advantages provided by the dense phase weighing system are said to include low fines generation, low investment cost, no rotating parts in contact with product, simple technology, low maintenance, low headroom head·room n. 1. Space above one's head, as in a motor vehicle, above a doorway, or in a tunnel; clearance. 2. Electronics Dynamic headroom. , and more. Motan Materials Handling Materials handling The loading, moving, and unloading of materials. The hundreds of different ways of handling materials are generally classified according to the type of equipment used. Circle 96 on card |
