Using a roller press to compact your low-moisture by-products for recycling — Part I
Waste by-products from manufacturing plants, coal-burning power plants, and other operations can create bulky, costly, or even hazardous disposal problems. Agglomeration equipment can treat these by-products so they can be recycled — either by sending them back to your process or using them to make new products. This two-part article concentrates on using one type of high-pressure agglomeration equipment, the roller press, to help you recycle low-moisture waste by-products by compacting them into various high-density shapes. Part II will appear in the March issue.
Roller presses have long been used to increase the bulk density of powders, granules, and shredded materials so they're less dusty and easier to handle and transport without degrading. But increasingly, these high-pressure machines are helping processors agglomerate low-moisture waste by-products for recycling. Recycling can include sending the by- products back to the original process, creating new products from them, or selling the by-products for use as secondary raw materials in other products.
