Premium Quality Calcined Bauxite for High Friction Surfacing & Asphalt


I am a Business Representative for Orient Abrasives Ltd (associate company of Ashapura). Established in 1960 the group is India’s largest muti-mineral solutions supplier & supplier of Calcined Bauxite.


                                                        

Orient Abrasives Ltd. (OAL) provide high quality competitively priced Calcined Bauxite. The PB 1000 grade, typically 1-3mm is used for High Friction (Anti-skid) Surfacing. A finer grading is available for specific Surface Treatment processes. It is also available in larger sizes for use in High Skid Resistant Asphalt. The colour is a distinctive dark grey. With it's very high Polished Stone Value(PSV) and exceptionally low Aggregate Abrasion Value (AAV) & Micro-Deval, OAL's Calcined Bauxite is the ideal product for incorporation in long lasting durable HFS systems. OAL offers: 

  • Extremely competitive prices DDP ex India
  • Excellent logistics
  • Warehouse facility in Antwerp for top up & urgent orders in Europe, lead time 1 week
  • High PSV product with exceptionally low AAV & Micro-Deval
  • Compliance with BS 8870, UK Clause 924, BBA/HAPAS, New Zealand, Australia, Ireland and multiple US state standards
  • Colour consistent product

Over the last number of years, OAL have supplied thousands of tonnes to the UK, US, Australia & New Zealand for HFS installation. The group's proximity to ports and the fact that they own their own port and fleet of ships gives them the competitive edge in today's challenging  market environment, where costs, quality and time are of the essence. Ashapura & associated companies have the scale & logistical capability to efficiently produce & deliver large quantities of product. 

Calcined Bauxite is obtained by calcining (heating) superior grade Bauxite at high temperature, which removes moisture, thereby increasing the alumina content. Compared to an alumina content of about 57 % to 58 % in raw Bauxite, Calcined Bauxite has an alumina content (Al2O3) of 84 % to 88 %. The heating is carried out in rotary kilns and is calcined at temperatures from 1200º C - 1800ºC. The calcination plant is situated at Jam-Khambaliya in Saurashtra region (India) with an annual capacity of 100,000 tonnes. The plant is within a radius of 50 kms to major international ports.   

A whitish buff stone PB 500 is also available. This is suitable for decorative applications where skid resistance is important.
