About CDC Dust Control

CDC specialises in designing, developing and manufacturing components for dust suppression and integrated dust suppression systems used on continuous miners and road headers.

Who we are

CDC is an African leader in dust suppression technologies for the mining and industrial sectors.

A level 1 B-BBEE company, we are the only company in Africa that has the specialised ability to ensure effective dust management for both continuous miners and road headers. We also offer practical and powerful dust suppression solutions for conveyors and transfer points in mining and most industrial plants across Africa – and, in the mining sector, this extends to both above- and underground applications.

Proving our specialised ability, CDC Dust Control worked with the Department of Minerals & Energy (DME), the Council for Scientific & Industrial Research (CSIR), and recognised South African higher learning institutions to establish the dust suppression requirements for South African Mines.

We not only manufacture and distribute our specialised dust suppression systems into Africa, but also provide a maintenance and repair service that covers all equipment in our range. All our dust control and dust suppression solutions are backed with customer support and service offering.

Sasol and Anglo American use CDC equipment & solutions for their dust management requirements.

Mission & Vision

Vision

To be a respected global enterprise working under the banner of continuous product and service improvement, and to harness our skills in supplying researched and competitive technologies that excel in selected markets.

Mission

To improve and expand the range of gas and dust management products required by modern industrial and mining technology, and to capitalise on growth opportunities domestically and international through process, service and product innovation.

A brief history

Our origins stem back to the late 1980s, when Erol Ribbink began experimenting with methods of capturing dust in collieries in his spare time. His dust capturing initiatives began bearing fruit in the early 1990s, and Ribbink was joined by current CDC operations director, Bob Johnstone, at the company’s Bredell premises in Kempton Park.

Increasing production levels at coal mines and higher dust loads in the early ’90s led to heightened awareness of health and safety issues pertaining to dust. In 1993, Doug Hudson bought the company and Colliery Dust Control Services was launched on 5 November 1995 and relocated to a Springs-based premises.

This new ownership began at the time when the impact and dangers of increased mine dust loads were being investigated. The company worked closely with the Department of Mineral Resources (DMR) and the Council for Scientific & Industrial Research (CSIR) to develop its range of dust suppression solutions.

In 2009, CDC was sold to the National Empower Fund with a number of existing personnel retaining a shareholding.

The company partnership structure comprises:

  • Managing Director: Gavin Ratner
  • Operations Director: Robert Johnstone
  • Financial Manager: Louise Mawhinney
  • HR Director: Thembi Chagonda
  • Shareholder: National Empowerment Fund

New name, same tailored solutions

The company’s original focus was colliery dust control, hence its founding name, which was shortened to CDC for brevity. However, the company’s solutions are designed to be used for dust suppression and control, and gas and dust scrubbing, in the majority of mined minerals.

To this end, in 2020 a decision was made to rebrand the organisation and omit the word ‘colliery’ from the name. However, it was important to maintain the company’s existing recognition.

A decision was therefore taken to use the former acronym, CDC, as the company’s official trading name. We are now known as CDC Dust Control.

Engineering capabilities

Engineering drawings

To engineer products tailored for your ideal solution, CDC uses a range of engineering drawing tools, including:

  • Solid Edge ST8, Siemens NX
  • A1 Plotter
  • CAD files supported (IGES, Step, Parasolid, Inventor, Solid Works, AutoCAD)
  • Drawing management using PLM programs

Product testing

We conduct thorough product testing at our plant:

  • Fan volume flow
  • Fan pressure delivery
  • Power consumption (electrical & hydraulic)
  • Water flow
  • Fan noise & vibration levels
  • Booster pumps
  • Scrubber box resistance

Design analysis

Our offboard scrubber units are designed to be used anywhere onsite, and incorporate a control system which is essential in helping eliminate failures. It prevents equipment failure by tripping the scrubber system and alerting operators. We carry out equipment design analysis in-house to ensure our products meet all industry and legislative requirements. We also work to reduce costs for our customers.

To do this, we conduct:

  • Vibration analysis
  • Static & Dynamic Finite Element analysis
  • Computational Fluid Dynamics (CFD)

Pump workshop

We have an in-house pump workshop which is used to carry out hydraulic and electrical testing, as well as revolutions, flow and pressure.

Pump repair services are also carried out at the facility, and test certificates are issued for each pump tested that certifies its compliance to original design parameters.

Accreditations

Our products meet the highest quality accreditations:
