John Thompson APC wins new de-dusting contract.


ppc-slurry-fm4-mill-upgrade_smACTOM Group business unit John Thompson Air Pollution Control was recently awarded a multi-million rand contract by leading cement producer PPC Ltd to replace the original finishing mill 6 electrostatic precipitator (ESP) with a bag filter at its De Hoek factory in the Western Cape.

The reverse-pulse bag filter will reduce dust emissions to the required legislative limits.

The replacement of the ESP with a higher performing dust control system is similar to an upgrade John Thompson APC – then known as ACTOM Air Pollution Control – performed at De Hoek three years ago to enhance the de-dusting system of its kiln 6 and raw mill 6.

As with the earlier upgrade, the new contract has been commissioned to ensure that dust emissions

from finishing mill 6 are maintained at less than 30 mg/Nm3 in accordance with the current environmental regulations. The contract was awarded in November last year for completion in March 2016, with a phased implementation due to cement demand.

The new bag filter, which will have a design air-moving capacity of 41 000 actual m3/h, will incorporate a variable speed drive induced draft (ID) fan and materials handling equipment consisting of a screw conveyor and rotary valve that will discharge the collected dust into an existing product conveyor.

ACTOM (Pty) Ltd is the largest manufacturer, solution provider, repairer and distributor of electro-mechanical equipment in Africa, offering a winning and balanced combination of manufacturing, service, repairs, projects and distribution through its 40 distribution outlets throughout Southern Africa.

ACTOM is also a major local supplier of electrical equipment, services and balance of plant to the renewable energy projects.

It also holds numerous technology, distribution and value added reseller agreements with various partners, both locally and internationally.
