Roller press
1.A new cement and saved energy power grinding equipment; 2.Ruduce the steel consumption and noise;
3. Hydraulic

2014 Hydraulic Roller Press for Cement Plant!

  

1.High Pressure Grinding

With our Roller Presses, the grinding pressure is transferred from the hydraulic system via the movable roll to the material bed and absorbed in a stable, closed machine frame. A key feature is the mounting of the rollers in oillubricated cylindrical roller bearings. The oil is both, lubricant and cooling agent. Alternatively, grease lubrication is possible. Power transmission from the electric motors is effected via cardan shaft, fluid or safe set coupling and clamping disc fitted gear boxes, usually of planetary design. Depending on the application, the rollers are either one piece solid construction or shaft and tire design with suitable wear protection for almost all applications in the cement and minerals industry

 

2.Always up to expectations.

The Yuhong Brand Roller Press is available in eight standard sizes ranging in grinding force from 2 to 20 meganewtons. Yuhong Roller Presses offer a reliable solution for every application for grinding cement, slag, raw material or for special applications, such as preparation of ore.

 

3.A framework you'll work better with.

The machine frame has identical upper and lower tiebars. Rubber pads are placed between the roller bearing blocks and the frame ends. The rubber pads act as an articulated joint and have a vibration damping effect. The RPS-type as a special type reduces maintenance time during roller changes. The doors in the roll cover permit rapid and wide access to the rollers for inspection and maintenance.

4.Roller Presses: roller support

A question of the right bearings.

5.Roller Press rolls and bearings.

In Yuhong Roller Presses, the rollers are supported in radial, multi-row cylindrical roller bearings. This ensures an even load distribution on the roller bearing, substantially increasing the life of the bearing.

6.Additional long life design features of Yuhong Roller Presses include:

• Generously sized bearing load factor
• Continuous feeding of filtered lubrication oil
• Bearings cooled by the lubrication oil for low bearing temperature
• Bearing sealing with fixed radial shaft sealings arranged back to back
• Additional permanently greased labyrinth with V- ring and separate dust
• labyrinth on the inner side of the bearings.

Oil lubricated roller bearings are standard with all Yuhong Brand Roller Presses. All contact points on the cylindrical roller bearing are supplied evenly with lubrication. Operating cost can be further reduced by checking the state of lubricant regularly (alternative grease lubrication).

7.Roller Presses: rollers, surfaces

Reduced wear by autogenous wear protection.

8.Grinding Rolls:

Yuhong Brand  Roller Presses offer rollers with appropriate wear protection for almost all applications in the cement and minerals industry. The two-part roller consisting of shaft and tire allows for economical surface replacement, single part rollers are used for high temperature grinding:

• Multi-layer welding enables long running times without stoppages.
• The complete hard face welded surface is used for feed material of normal wear characteristic. Surface repair can be carried out quickly.
• The surface with hard-alloy studs is used for extremely abrasive materials.
