The corncob grains are known to have high abrasion resistance, good moisture absorption, low specific gravity and are employed mainly for drying in the Rotary Dryers and Vibratory Dryers. Walnut shell is a hard and fibrous material of medium abrasiveness, and is used in both the polishing and deburring processes as it leaves no scratches or pitting. Pre-treated Media All of our agro media comes in a treated, bovine-free form, which is particularly suitable for high lustre or mirror finishes. Special Media Our special media includes steel media; a separation ball media that keeps flat parts separate, ensuring they don t stick together. 14 15
Additional Services Value Added Service On top of our state-of-the-art machinery and media, we also supply a range of support and training services. Learn more on how you ll benefit: Waste Water Treatment During the finishing operation, the effluent can be polluted with oil, media and metal fines. It is critical that the effluent must be treated before going to drain, or if it is being recycled back into the system. Each area or district has its own discharge consent, hence the effluent must be analysed against this. The effluent can be recycled, however there are certain applications where it is not possible. In those cases, the treated effluent can be transferred directly to the drain. Recycling can save on the significant amount of water and compounds (greater than 90%) used. We offer a range of flocculants (powder and liquid) coupled with our Centrifugal technology. Please refer to our waste water treatment brochure for more details.
