grinding process sulfur - Bussa Machinery

Size reduction of waste rubber is carried out in two steps. In the grinding process, the breakdown of particles is the primary objective so that the obtained crumb rubber can be fed into the subsequent processing stages. The successive stage is breaking of the chemical bonds (primarily sulfur bonds) in a process called devulcanization. Read More

Effect of grinding with sulfur on surface properties and ...

01.11.2017· Basic researches have been conducted on the transformation of oxides into sulfides by co-grinding with sulfur and reducing agents such as iron or aluminum powders [28−31], allowing the use of cheap sample of element sulfur to replace sulfides as sulfidizing agent.
