The roller press is a highly efficient and energy-saving choice for grinding hard and medium hard materials. It is widely used in manufacturing and/or processing of raw meal, cement, slag non-ferrous metals and iron ore. When upgrading the capacity of ball mill systems, it is the best choice of equipment. A roller press can be used as a pre-grinding system or in a combined grinding system with ball mills. Independently, it can also operate as a finish grinding system.

Characteristics:

• High output, high reliability and low energy consumption.
• Relatively high working pressure, low vibration and stable operation.
• Smaller rollers are forged in whole from quality alloy steel before welding the hard-facing layers. They are highly reliable and can be repeatedly re-welded; larger rollers are split into shaft and tyre, which guarantees better quality of the shaft and ease of replacement of the roller tyre.
• Available roller surfaces: hard facing, composite and embedded studs.
• Four-row cylindrical roller bearings ensure high bearing capability and long service life.
• The calibration device for material feeding stabilizes roller gap from fluctuation.
• The smart roller bearing lubrication system supplies to each lubrication point separately.
• Due to the smart design of the control system, the roller press can be operated and controlled under the optimum working condition without great effort.

Hydraulic System:

• Oil lubricated roller bearing are now standard with all roller press. All contact point on the cylinder roller bearing are supplied evenly with lubrication
• Cooperation with professional hydraulic pressure plant
• Imported key component
• Highly integrated hydraulic pressure system—reliable operation
• Easy installation of oil tube
• Very few tube joint—no leakage

Structure of feeding system:

• The plates flexible will adjustment feeding volume by the feeding device.
• There is 50 ~ 120mm adjusting range for adjust the throughput of roller press
• The standard deviation reduced based on feeding device

Four-row taper roller bearings:

• High bearing capacity
• Long lifetime
• Reliable seal effect
• High pressure and large diameter oil cylinder—high extruding efficiency

Surface form of roller and roller sleeve:

• Offer roller with appropriate wear protection for almost all application in the cement and minerals industry. The two-part roller consisting of shaft and sleeve allows for economical surface replacement. The materials used in the two-part roller are perfectly matched to each other for strength and welding properties.
• In order to suit for different material and working condition, SINOMA developed the super wearable sleeve and hard alloy pins sleeve for roller
• Super wearable sleeve is multi-layer by centrifugal casting enables long running times without stoppages. The complete hard surface is used for feed material of normal wear characteristic. Surface repair can be carried out quickly.
• The hard alloy pins sleeve is used for extremely abrasive material. As it widely used for minerals industry.

A driving force: reasonable stressed:

• The drive power is transferred to the grinding roller via multi-stage planetary gear box with first stage.
• The gear box mounted on the drive end of the roller shaft using locking disc. gives absolute safety. The torque supports are linked directly to the machine foundation.
• This arrangement prevents torque related stress from acting on roller shafts and bearing.
