Briquetting Without Binders
Briquettes made with binders are usually pressed at low pressure.
When briquettes are made without binders, however, the success of the process depends upon crushing or plastically deforming the particles to bring them closely together. It is not surprising that many crystalline organic components can be briquetted with pressure alone. The forces that bind these crystals together are neither strong nor specific, so it is necessary only to squeeze the individual crystals into close contact.Because of the mandatory squeeze rollers, the products have high density, high strength, high hardness, and the local roll is used in 650Mn hard materials with good wear resistance. Effectively improve the life of rolls
Briquetting With Binders
Many other materials are briquetted with binders.
Iron and chromite ore are briquetted with a binder consisting of lime and molasses.
Fluorite also is briquetted with lime and molasses binder as well as with sodium silicate.
Portland cement is used as a binder for bauxite Lignosulfonate binders which are a residue of
the paper industry are used for copper ores and for magnesite. In glass batch mixes, water and
soda ash form a binder for the silica sand.
