Scrap Graphite Recovery
Coidan Graphite Products can re-process your scrap graphite and convert it into reuseable parts such as furnace bricks or small consumable machined items - those pieces that are not suitable for re-machining are then crushed and used for recarburiser.
Recarburiser
We offer a full range of recarburiser, natural graphite and activated carbons to suit the bulk needs of major manufacturing industries.
Granular graphite
A wide range of carbon, coke, and graphite granular products are sold by Coidan Graphite Products Ltd.
The range is from typical coarse particles to special fines with various classifications according to customer requirements.
Packaging is bags, drums, or bulk. The variety of applications for these products is a result of differences in grade, particle and chemistry.
