Roller Press

KHD’s leadership in grinding modifications has helped customers worldwide find inexpensive and energy-efficient ways to increase their capacity. Roller Press installations are available in Finish or Semi-Finish modes and suitable for highly abrasive materials, material with high moisture content, and are proven superior for Limestone, Clinker, and Slag grinding.
Features
  • 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
  • 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.
Benefits
  • A Better Framework
    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.

  • Better Bearing Life
    In KHD 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.

  • 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.

  • Better Longevity
    Reduced wear by autogenous wear protection.

KHD Roller Presses can be utilized in new plants or to enhance existing plants.

Specs & Sizes

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

Fans

Humboldt Wedag GmbH mainly manufactures fans for the cement industry and can look back on a long tradition and experience and carry on this basis. The fields of application of the KHD fans primarily are the transport of hot gases and dusts.
Features
  • Raw meal fans with high dusts loads and high differential pressures
  • Preheater fans, suitable for temperatures up to 450 °C with narrow blades for operation at low vibrations and at the same time low tendency to form accretions and high effi-ciency
  • Dedusting fans for kiln waste gas dedusting, cooler- and bypass dedusting for large volumetric flows at low pressures
  • Fans for cement grinding with particularly abrasive wear
Benefits
  • Unparalleled Toughness
    Thanks to their robust construction the KHD fans are designed for especially rough operating conditions at a high degree of operational safety. For all materials used great importance is attached to good weldability and high toughness.

V Separator

Originally developed to separate fine material from a roller press circuit, the V-SEPARATOR has, however, also proved its value in tough applications with large mass flows and abrasive material of wide size range and high levels of feed moisture.

Material is fed from above to the builtin step grate. From here, the fine material is carried upwards with the air through the separating channels, the coarse material falls down over the step grate and is discharged at the bottom of the housing. The ratio of material load to separating air can be up to three times higher than with an airstream separator.

  • Separating fine material from fresh material
  • Drying moisture from fresh material
  • Cooling hot fresh material
  • Deglomeration
  • Mixing fresh material and grits
  • Preventing formation of deposits when grinding granulated slag by positioning the V-SEPARATOR underneath the roller press.
  • Producing a finished material with custom tailored grain size distribution by combining V-SEPARATOR and cage wheel separator.
  • Virtually Unlimited Use
    The required product fineness is achieved by adjusting the air speed in the separating channels. Cut point range is from approx. 80μm to 1.5mm.

  • The Benefit To You
    The V-SEPARATOR is an uncomplicated static separator without any moving parts. Since it carries out a whole range of process functions, it considerably extends the range of applications for high pressure comminution. In addition to reduced investment for machinery, the V-SEPARATOR also results in energy savings. With the rising cost of energy, this will become increasingly important.

  • Limited Wear & Tear
    All internal parts are fixed and have straight and level surfaces, as does the housing. This ensures simple but effective protection against wear, eliminating the need for maintenance work for many years.

Combines With
SEPMASTER

High-performance separators have a long tradition at KHD Humboldt Wedag. The SEPMASTER provides excellent selectivity and fits into small space. In addition to installation in new mill circuits, the SEPMASTER is particularly well suited for increasing the productivity of mills already in operation. The innovative rotor cage system enables the grinding of premium product qualities. The investment cost incurred by a change of separators is quickly recovered.

  • Depending on size and application, the SEPMASTER separator is available in various versions and with specifically tailored protection against wear and tear.
  • Rotor Stability
    The rotor shaft is supported at both ends. This concept avoids vibration and ensures a smooth and safe running machine, even when producing very fine products.

  • Drive on the bottom
    For maintenance work on the separator, gearbox, motor and electric cables do not need to be moved. The drive is positioned away from the heat and easily accessible.

  • The bearings are outside
    The support bearings are located outside the separator housing and can be easily installed or removed, whilst the cage wheel remains in normal position.

  • Resistance to wear and tear = lower costs
    Easily replaceable parts made of high quality materials such as cast basalt, ceramics, chromium carbide or chilled iron guarantee long life.

  • Fits comfortably into small spaces
    The SEPMASTER is the perfect replacement for old separators. Compared to older generation separators, the cage wheel separator is not only more efficient but also significantly smaller and lighter.

  • Efficiency of separation
    Precise separation was previously only possible on a laboratory scale, but can now be achieved in large plants because of the SEPMASTER’s high performance.

VSK   (V + SK = VSK®, VSK® Separator)

VSK® Separator

The VSK® combines the sturdy design of the V-Separator with the high performance of the SEPMASTER. The cage wheel is arranged as an add-on module to the V. With the V and VSK® Separator, the need for auxiliary equipment is greatly reduced: no separate dryer, no deglomerator. New ways of process design are now open to a wide field of applications for new plant and upgrade alike. Wear is minimized, even when grinding abrasive materials. These new systems are not exclusively bound to the roller press, but can be applied in grinding circuits with tube mills and impact hammer mills. Tailor-made solutions by KHD Humboldt Wedag are available.

  • Five jobs in one unit
  • Relieving the dynamic classifier of coarse material by pre-classifying.
  • Mixing feed and recycled material before entering the roller press.
  • Deglomeration of RP discharge by impact action of the cascade.
  • Drying / cooling.
  • High efficiency classifying.
  • Cut size between 25 and 150μm.
  • Effective wear protection.

VSK®e Separator

The VSK®e Separator will require significantly less mechanical conveying capacity. To accomplish this, the VSK® is split into two parts. The static “V” – part underneath the roller press and the dynamic “SK”- part above the roller press are connected by a riser duct (e), over which all fines from the “V“- part are lifted by air flow to the “VSK®“- part.

  • Minimizing of bucket elevator capacity
  • Higher feed rates can be processed
  • Reduction in building volume
  • Lower capital investment
