OptiTromp Separators for Ball Mills

High efficiency separators for bulk materials

 

From high efficiency separators in their OptiTromp family through to the all-in-one aggregate Heyd Separator on to the JS Classifier, which was developed especially for the high demands of the minerals industry: Christian Pfeiffer offers you a variety of separators to meet the special demands of your production lines.

 

QDK cross-flow rotating cage separator

A separator for every need

 

It is no surprise that the proven QDK high efficiency separator is the most popular product in Christian Pfeiffer’s OptiTromp family. The standard version of the cross-flow rotating cage separator can be integrated into almost any grinding plant. Top cuts of up to 10 µm can be produced, thanks to the particularly constant separating conditions within the entire separating zone.

  • High efficiency separator from the OptiTromp family
  • Top cut up to 10 µm
  • Constant separating conditions within the entire separating zone.
  • Air flow and speed of the rotating cage can be adjusted according to the required finished product
  • Standard version fits nearly every grinding plant
  • Circulation fans and cyclones ensure consistent optimisation of the finish product output
  • Alternative filter for finish product recovery: cooling of products and grits possible to 70oC
  • Avoidance of oversized particles due to wear-free confined air seal of rotating cage
  • Convenient maintenance thanks to large inspection doors for easy access to motor and bearing cartridge

TGS Top Gas Separator

The Christian Pfeiffer space saver

 

The compact design of Christian Pfeiffer’s Top Gas Separator allows particularly flexible installation and demonstrates its advantages especially when modernising existing plants. With a top cut of up to 10 µm, it is installed instead of a QDK separator in plant layouts where space is an issue.

  • Space-saving high efficiency separator from the OptiTromp family
  • Top cut up to 10 µm
  • Compact design through upward finish product output
  • Constant separating conditions within the entire separating zone
  • Air flow and speed of the rotating cage can be adjusted according to the required finish product
  • Avoidance of oversize particles due to wear-free confined air seal of rotating cage
  • Convenient maintenance thanks to large inspection doors for easy access to motor

DSL Dynamic Airflow Separator

The raw meal, coke and coal pro

 

The dynamic airflow separator (DSL) is used in airflow mills and is primarily used in grinding petcoke or coal as well as raw meal. Depending on the material to be ground it can also be used to separate other products such as minerals, limestone, feldspar or quartz sand. The input material enters the DSL with the separator airflow from below and is sucked upwards into the separator by the airflow. It provides a top cut of up to 20 µm.

 

  • Airflow separator from the OptiTromp family
  • Suitable for use in grinding plants for petcoke, coal, and raw meal
  • Top cut up to 20 µm
  • Material input through airflow
  • Air flow and speed of the rotating cage can be adjusted according to the required finish product
  • Avoidance of oversize particles due to wear-free confined air seal of rotating cage
  • Also available in an impact-resistant version (e.g. for separation of explosive materials)

TFS Twin Feed Separator

For combined roller press and ball mill grinding systems

 

The TFS is a dynamic separator working together with a static separator in a so called DSS (Dynamic Static Separator) system. These separators were specially designed for the use in combined grinding systems which consist of roller press and ball mill. The material enters the TFS through two feeding points:  through an airflow and through two feeding chutes above the separator. The TFS provides a top cut of up to 20 µm.

 

  • Separator from the OptiTromp family for combined roller press and ball mill grinding systems
  • Top cut up to 20 µm
  • Two feeding points for material via an airflow and through two feeding chutes
  • Air flow and speed of the rotating cage can be adjusted according to the required finish product
  • Wear-free confined air seal for rotating cage

DSM Dynamic Mineral Separator

For dry materials

 

The dynamic mineral separator is especially designed for the use with vertical mills and is suitable for the separation of products with relatively little moisture, for example for the grinding of minerals. The DSM is fed from below and supplies a top cut of up to 20 µm.

  • Vertical mill separator from the OptiTromp family
  • Suitable for products with low moisture content, e.g. minerals
  • Top cut up to 20 µm
  • Constant separation conditions in entire separating zone
  • Airflow and rotating cage speed adjustable according to required product grade
  • Wear-free confined air seal for rotating cage
  • Convenient maintenance thanks to large inspection doors for easy access to motor

DSK Dynamic Coal Separator

For damp materials

 

The dynamic coal separator (DSK) is used in cases where materials with high feed moisture are ground. The vertical position of its centrally-positioned feeding chute prevents the damp material from sticking. The material to be ground thus goes directly to the grinding table of the vertical mill. The DSK is often used for the separation of coal or petcoke and provides a top cut of up to 20 µm.

  • Vertical mill separator from the OptiTromp family
  • Suitable for products with high feed moisture, e.g. coal or petcoke
  • Top cut up to 20 µm
  • Constant separation conditions in entire separating zone
  • Air flow and speed of the rotating cage can be adjusted according to the required finish product
  • Wear-free confined air seal for rotating cage
  • Convenient maintenance thanks to large inspection doors for easy access to motor and bearing cartridge
  • Also available in an impact-resistant version (e.g. for separation of explosive materials)

JS Classifier

The minerals specialist

 

The JS classifier was developed for the high demands of the minerals industry. The ultrafine separator provides a top cut with grain sizes from 10 µm to ultrafine 1 µm. The patented motor-rotor unit together with the controlled material feed ensures optimum finish product output and up to 30 percent more efficiency in comparison with conventional ultrafine special separators.

 

  • Special separator for the minerals industry
  • Top cut from 10 µm to 1 µm
  • Patented motor-rotor unit for circumferential speeds up to 190m/s
  • Variable motor speed adjustable to product grade
  • Controlled patented adjustment of material feed by alteration of the grit flow
  • Works with overpressure for optimum and constant separation conditions
  • Up to 30% more efficient than conventional separators

Heyd Separator

The universal talent

 

With a top cut of between approximately 60 µm and 200 µm the Heyd separator improves the quality of the final product enormously. The Heyd separator is an all-in-one aggregate – thus neither cyclones nor filters to discharge finish product nor a process ventilator are required. An integrated adjustable fan wheel and reverse flow blades ensure optimum finish product output.

 

 

  • Top cut between approx. 60 µm to 200 µm
  • One aggregate only. Neither cyclones, nor filters for finish product output and process ventilators are required
  • An integrated adjustable fan wheel and reverse flow blades for optimum finish product output
