Refractory

A refractory is a materials that can withstand very high temperatures, 3000°C or more, without degrading or softening. Refractory materials include certain ceramics and superalloys, and are used in heat insulation of kilns. [... more]

Retort

A retort is a vessel or chamber in which material is processed at high temperature. [... more]

Retrofitting

Retrofitting is adding a component or accessory to something that did not have it when manufactured or to upgrade an older piece of equipment. It allows new parts, components and technology to be added to ensure optimal operation of equipment. [... more]

Ring-torsion load cells

Ring-torsion load cells are based on the basic principle of strain gauge load cells. They use electrical signals such as current and voltage to determine mass. [... more]

Roller Mill

The Raymond® Roller Mill is an air-swept vertical pendulum mill with integral classification. The typical system is designed to dry, pulverize, classify to deliver a number of products. It provides efficient control of product size with minimal power resu [... more]

Rotary Airlock

Rotary airlocks are used to discharge bulk solids materials such as powders, granules, and pellets from hoppers, bins, receivers, and cyclones into a pneumatic conveying system [... more]

Rotary Airlock Feeder

Rotary airlocks are used to discharge bulk solids materials such as powders, granules, and pellets from hoppers, bins, receivers, and cyclones into a pneumatic conveying system [... more]

Rotary Cooler

A rotary cooler is designed using a rotating cylinder. The material to be cooled is fed into one end of the cylinder and cooled either directly, by showering the material through a cool air stream utilizing lifting flights, or indirectly, by spraying wate [... more]

Rotary Cylinder

Rotary cylinders are used in rotary equipment such as rotary dryers and rotary kilns. They are fabricated cylinders that include new cylinders, retorts, replacement cylinders and cylinder sections that can be provided in carbon steel, stainless steel or [... more]

Rotary Dryer

Rotary dryers are designed using a rotating cylinder. With two basic designs, directly and indirectly heated, they are readily adaptable to a wide variety of processing applications, as stand-alone units or as part of complete thermal processing systems. [... more]

Rotary Valve

A rotary valve is a device that can be designed to discharge bulk solids materials such as powders, granules, and pellets from hoppers, bins, receivers, and cyclones into a pneumatic conveying system [... more]
