How to Make 2-10mm Alumina Granules in Austrialia?

On September 3, 2024, our company received an inquiry from a mining company in Gladstone, Australia. As is known to all, Australia, rich in mineral resources and the world’s largest exporter of alumina, presents significant opportunities in mineral processing. Thus, this Australian customer operates a mining enterprise with a certain ore processing capability and existing equipment. And he wanted to agglomerate alumina powder and dust—byproducts of aluminum ore and bauxite processing—into mineral fertilizers for the local market. So they sought a 1 t/h alumina granulation plan with the budget of $30,000 USD.

What Equipment Can Produce 1 T/H Alumina Fertilizer Pellets?

The customer detailed their needs meticulously. They required a 0.8-1 t/h fertilizer granulation plan to process alumina powder without the need for moisture. Moreover, the feed particle size of alumina powder ranging from 0.05–5mm and they required the finished fertilizer granule size of 2–10mm. Notably, the feed temperature was at 80℃. In response, our company proposed a cost-effective solution that focuses on dry granulation, a method that does not require water.

Dry Granulator to Meet No Water Requirement of Alumina Pellets

Considering Australia’s recent water price reforms, where water prices increased by 10%, and from July 2024, the cost exceeded 5.15 AUD per kiloliter beyond 50 kiloliters, reducing water usage became crucial. So this increase in cost has led the customer to specifically request a granulation process that would not require moisture addition. Initially, the customer considered a new type organic fertilizer granulator. However, we explained that this equipment is designed for wet granulation of organic fertilizers, which involves moisture and agglomeration methods unsuitable for alumina powder. Instead, we proposed the 1 T double roller granulator, which employs dry granulation technique. This method can produce alumina pellets without adding water or with a minimal addition of 4-8% water to enhance pellet cohesion.

High Temperature Resistant Design to Enhance Service Life of Alumina Granulator

Nevertheless, the alumina powder’s feed temperature is 80°C, which is relatively high. To improve the dry granulation machine’s service life, we customized stainless steel roller sheets to enhance durability.
The customer expected the product size of 2-10mm. We requested more precise specifications to customize the extrusion granulator’s ball socket diameter accurately. Ultimately, we provided two sets of stainless steel molds: one with 3-4mm ball sockets and an additional set with larger 8-10mm ball sockets to meet their product size range.

Auxiliary Equipment & Dust Control Measures

This Australian customer said the feed particle size of alumina powder ranging from 0.05mm to 5mm, which aligns perfectly with the roller press granulator’s feeding requirement, eliminating the need for additional grinding machinery. Additionally, we recommended several auxiliary machines to ensure smooth and efficient alumina fertilizer pellet production. The SXFM-2030 loader type feeder and the SXPJ-1600 disc feeder were selected to ensure even feeding of the alumina powder into the granulator. Then, we suggested buying SXGS-1020 granule screening machine to sort the finished product and return any oversized alumina granules for re-processing. Furthermore, a SXLTF-500 chain crusher adequately crushes oversized alumina particles to below 3mm for re-granulation. To meet the customer’s dust control requirements, we installed dust covers on the screening machine and all conveyor belts.

How to Transport 1 T/H Alumina Pellet Production Equipment to Mining Company in Australia?

This Australian mineral company sent representatives to visit our Yushunxin factory on September 30, 2024. And they paid the full amount of $26488.90 USD for 1 t/h alumina granule manufacturing machines directly on October 15^th. We spent 7 days to finish these equipment production. Then, we shipped the equipment from Shanghai Port on October 25^thto Gladstone Port, and the shipping time was 27 days. So one 40GP container FOB Shanghai Fees are totally at $4274 USD. After arrival, there are additional 5-7 days for customs clearance and inland transportation to customer’s mining factory in Gladstone.
