Double Roll Crushers

We are counted amidst the well-known names involved in providing quality products from Asansol(India).We team makes sure that all the trade transactions are made keeping all the details of the clients confidential.

Function

• Ajmani manufactures the double roller crushers separate the feed material with high pressure.
• The driven toothed rollers draw the material into the crushing gap.
• Due to the high impact rate of the circulating crushing tooth segments the effective crushing action starts already above the toothed roller.

Design

• Welded robust housing
• Roller core shaped as a polygon with surface-ground supports for the crushing tooth segments
• Locking of the segments by means of dovetail guides and fastening by screwed bolts
• Tooth shape and tooth pitch are adapted to the respective application
• Crushing tooth segments individually replaceable without lifting the crushing roller out
• Crushing roller alternatively available with crushing rings
• Stationary and loose rollers with dust light encapsulated anti-friction bearing
• Stepless setting of crushing gap with optional mechanical or hydraulic overload protection
• Parallel evasion of the loose roller on the occurance of uncrushed components of the material

Fields of application

• Cement,gypsum and limestone plants
• Coal,ore and potash mining
• Building,glass and chemical industries
• Metallurgical plants

Advantages
