Evaporator Dryer Technologies provides a spray chilling process by means of a Prilling Tower. Our Prilling Towers allow for the formation of uniform or random spherical product particles derived from molten product. The Prilling Tower is designed with a full diameter air disperser at the bottom of a high tower to evenly distribute chilled air
ammonium nitrate may be produced in the form of prills, grains, granules, or crystals. Prills can be produced in either high or low density form, depending on the concentration of the melt.

Rotary Forging ROTARY FORGING, or orbital forging, is a two-die forging process that deforms only a small portion of the workpiece at a time in a continuous manner. Unfortunately, the term rotary forging is sometimes used to describe the process that is more commonly referred to as radial forging, causing some confusion in ter-minology

Two Chemetals MnCl 2 prills rotary dryers each rated at 1.8 MMBtu/hr fired by natural gas and is back-up by propane gas. Both dryers are controlled by a packed tower scrubber (EP7-407A). The scrubber is used for material recovery. 1975 One boildown tank controlled by one packed bed scrubber (EP7-407B). The scrubber is used for material recovery
Rotary dryers are known as the workhorse of industrial dryers. They are able to process a wide variety of materials, and can lend a hand in nearly any industry requiring industrial drying solutions. Some of the most common industries and materials in which rotary dryers are employed include: Aggregates
Prills are spherical and naturally resistant to abrasion or damage. Since no additives are necessary in the prilling process, prills of your product are 100% pure. Thanks to their size and shape, prills have the smallest possible contact surface area and high bulk density. In bulk, prills behave like a fluid which is beneficial for transport
mm prill. Dried EQ biosolids prills exit the dryer to be sorted by size based on finished product requirements. Appro-priately sized prills are cooled and dis-charged to a storage skiff. Oversized material is crushed and mixed with fines to be sent back to the recycle bin. The recycled fines are used as the dry seed material to form the prill that
Drum Flaker Working Principle. The drum flaker is used primarily to pro-cess chemical and pharmaceutical prod-ucts. However, more and more applica-tions for these machines are also being found in the food industry. The closed design is ideally suited for processing of toxic or offensively smelling products
May 12, 2010 May 12, 2010 This invention relates to granules comprising a homogenous mixture of metal flakes and/or metal powder and metal oxide powder, and a binder. The invention also relates to a process for producing such granules. The process includes the step of forming a mixture of metal flakes and/or metal powder and metal oxide powder, forming the mixture into a homogenous blend, adding

Rotary dryer, consisted of drum, lifting board, transmission device and support device and other assembly parts, can be custom designed to suit the unique processing needs of customers’ material. The drum should be fixed at a slight horizontal slope (about 2-5 degree) to allow gravity to assist in moving material through the drum
