Roller assembly is the core part of briquetting machine. Particles are fed by squeezing them between two rollers rotating in opposite directions and then form final briquettes. It is composed of items such as main shaft, roller shell, bearing, bearing support and seals. Adopting high quality bearing steel, integral rollers are finished by multiply processes such as machining, UT, milling, hot treatment. After hot treatment, its surface hardness could be up to standard. All rollers are high wear-resisting and replaced easily. The main shaft is made of forging 40Cr, which is processed by multiple processes and processes such as drilling, turning, heat treatment and milling.
Roller shell and main shaft are assembled by an interference assembly, and then assembled into a roller assembly with corresponding seals such as bearings and bearing supports.
Our roller assembly has a high reputation in China and abroad because of its high quality and low price. It can be processed according to the drawings.
