Silica Flour Packing in Saudi Arabia
11 October 2006
Adwan Chemical Industries Co. Ltd .(ACIC) belongs to the Adwan group of companies within the inorganic chemicals manufacturing complex based in Second Industrial City, Riyadh. ACIC fully exploits two of Saudi Arabia's vast natural resources, oil energy and high-quality white silica sand, to produce various grades of industrial silica sand, silica flour and silicates. Adwan produce silica sand in four different grades for use in glazing in the ceramics industry, cementing in oil wells, fillers in paint industries, powder coast and marine paints, fillers for plastics and fibre optics, and construction chemicals.
By installing a new packing line, not only have ACIC been able to make the most of these natural resources, but they have also emerged as a reputed supplier of inorganic chemicals in Saudi Arabia and abroad.The order was placed after Adwan Industries' high-speed big bag filling system for silica flour had been a success using a Webster Griffin IBC-PF3 big bag filling machine. This had been used since 1993 for packing silica sand and sodium sulphate glass. An order was also placed for a Webster Griffin universal air packer for silica sand, packing at a rate of two to three bags per minute on 14kg to 50kg valves.
The machine installed was a Webster Griffin IBC-PF4, complete with a vibration table to consolidate the powder, an empty pallet magazine to stack the pallets, accumulating conveyors for five stacked pallets and a control panel. PE-coated woven polypropylene bags with four support loops and a central filling spout were used to fill fifteen to sixteen 1,000kg bags per hour.
The product is weighed using an Avery Berkel weighing system to weigh and fill fine, free flowing product into the bags. This product comes from Adwans' storage silo via a single screw feeder conveyor and a slide valve supplied by Webster Griffin. The platform-based filling machine is raised during the filling cycle. The carriage is then lowered at the end of the filling cycle to release the tension on the bag loops enabling the filled bag to be discharged from the machine; the carriage is then raised allowing the filled bags to exit the machine.
The bags finally conveyed to a warehouse where they stacked and ready for transportation, throughout Saudi Arabia and abroad.
