      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.

      High Pressure Grinding Rolls (HPGR)
      ZTIC designs and manufactures a range of HPGRs to suit the cement and mineral processing industries. Our HPGR designs range from 120-50 (2 x 355kW) to 240 -180 (2 x 3150kW).

      6. The main bearing adopts inner passage fully-sealing structure for cooling
      7. The hard alloy welding press roller surface or setting-in surface are available depending on the user’s need.

      Applicable scope

      1. Applicable for the mineral processing industry; it can be installed before the ball mill as pre-milling equipment or consist of mixing grinding system with ball mill.
      2. Applicable for oxide pellet industry instead of the common used damp mill.
      3. Applicable for building material and fire-proof material industry; successful application for the grinding of clinker, limestone and bauxite.

      Always up to expectations.

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

       

      A driving force: reasonably stressed.

      The drive power is transferred to the grinding rollers via multi-stage planetary gearboxes with first stage spur gears. The gearboxes are mounted on the drive end of the roller shaft using a hydraulic shrink coupling.. A V-belt drive can be used for drives of up to approx. 400kW per motor. Drives above 400kW are equipped with fluid or safe set coupling and cardan shaft.

      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.

       

      Roller Presses: roller support

      A question of the right bearings.

      Roller Press rolls and bearings.

      In ZTIC 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.

      Additional long life design features of CITIC 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 CITIC 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).

       

      Roller Presses: rollers, surfaces

      Reduced wear by autogenous wear protection.

      Grinding Rolls

      ZTIC 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.

      The principle structure of high-pressure roller mill

      High-pressure roller mill is a type of new mineral rock grinding equipment with high efficiency and energy-saving developed based on the lamination crushing principle. The materials enter into the crushing cavity between 2 rollers passing the feeding device with the help of the gravity when working. The material is brought into the cavity continuously. The material is forced to accept the direct pressure from the surface. The 2 rotary rollers will press the material in the crushing cavity solid so that the particles in the group will bear pressure at multiple points. Thus, the material volume weight in the pressing area is 85% of the actual density. The particles are crushed in the group be mutual pressing. Different particle crushing is caused due to different pressures. So the particle size is widely distributed and the piece of material cake is discharged. The material cake contains some sub-particles. There are many cracks in the particles to reduce the particle strength, which is good for the following grinding to reduce the power consumption of the whole milling system significantly.
