Benefits

The Underdriven Cone Mill Comil® series

High-capacity throughput cone mill with a compact design.

The Quadro Comil Underdriven Series has a compact, inline design with a short head height which allows for easy integration into powder milling and processing environments. It offers productivity improvements from world-leading technology. 

With a small footprint, inline design, and extremely short head height it can be easily integrated into processing environments where space is limited. A large-diameter infeed and “straight-through” housing promote unhindered inline product flow for quicker discharge, and therefore higher throughput, improving productivity.

Available in five models, the Underdriven Comil is scalable in capacity from several ounces (grams) to 35,000 lb/hr (15,900 kg/hr). The innovative spacer less design allows for quick changeover of impellers and screens. Plus, specialized tooling is available to meet all process requirements including handling heat-sensitive products.  We can help you choose the right screen and impeller.

As well as meeting the requirements of cGMP, we want to ensure that the machines we develop are well designed and safe for the user, so we follow a variety of specific industry directives.

All Quadro products are designed and manufactured in a facility with an ISO 9001:2015 accredited Quality Management System. 

The scope of this Quality Management System applies to all processes and activities which are controlled, managed and performed by employees within the Quadro Engineering company. 

The current Certificate of Registration, reference Certificate No: CERT-0123529, has been issued by SAI Global and is effective to September 2, 2024.

ISO-9001-LOGO-Horizontalweb

We offer a complete selection of ATEX-approved mills that meet the ATEX European Union directive for products used in potentially explosive atmospheres.

Our equipment is designed to handle the toughest milling applications, which is why professionals around the world choose us.   With models specifically designed to meet ATEX Zone 0,20 (1GD)  or 1/21 (2GD) requirements, we provide the most comprehensively safe mills in the industry.

accred-atex-web-1accred-ce_white-web-1                            

All equipment destined for Europe is CE marked and comes with an EU Declaration of Conformity or EU Declaration of Incorporation.   It is certified to comply with the Machinery Directive 2006/42/EC,  the Low Voltage Directive 2014/35/EU and the Electromagnetic Compatibility Directive 2014/30/EU.

Our equipment is designed to meet a variety of international safety standards, so whichever country you are in we can be compliant.

Discover how we have become the equipment of choice for a number of different applications and companies around the world.

Typical product applications include:

  • High throughput capacity size reduction of pharma, food and chemical materials
  • Wet Conditioning - wet milling material before drying creates a more uniform particles which dry more consistently.
  • Granulation of dry powders
  • Reducing sticky agglomerates into uniform-size powders
  • Material reclaim - both of tablets and foods e.g. cookies

The under driven mill can be installed for:

  • IBC to IBC milling 
  • Milling within an Isolator - where higher containment is necessary the mill can be located within an Isolator
