Metal Granulation.

Exclusive supplier of the Gran-Tech Molten Metal Granulation System.


  • Economy Industrial Metal Granulation

E-WASTE GRANULATION / COPPER, GOLD, SILVER, CADMIUM, PLATINUM.

Economy Industrial is the leading designer and supplier of hot metal granulation systems for the granulation of e-waste, copper and brass alloys.

The Economy Industrial, Gran-Tech e-waste alloy proprietary technology rapidly cools plasma heated e-waste alloy from 1600C to 120C in 30 seconds. The granules are then dewatered, pass thru a rotary dryer then stored for future process. The rapid cooling of the alloy during granulation keeps the high value metals copper, gold, silver, cadmium and platinum homogeneous during the cooling process.

The Gran-Tech Method.

The Economy Gran-Tech Granulation System is a state of the art method of solidifying liquid metal into pellets or granules that resemble marbles that are squeezed flat into irregular shapes. The granules are between 2-50 mm in size. The customer’s material handling systems generally requires granules that are flat and irregular in shape. The Gran-Tech granulation system solidifies, cools, dries, sorts and stores the granules for immediate packaging and shipment to customers.


The Economy Granulation System designed by ASWT is an effective granulation machine: it takes about 30 seconds for the liquid metal (1600 C or 1650 C) in the ladle to reach 100 C or 120 C at the dewatering screen.

PIG IRON, FERRO ALLOY GRANULATION.

Economy Industrial is the exclusive supplier of the Gran-Tech Molten Metal Granulation System to the Ferro Nickel, Nickel Pig Iron, Blast Iron, and Ferro Chrome producers located in the Peoples Republic of China. Alloying materials like Ferronickel, Ferrochrome and blast furnace iron have traditionally been cast in blocks, pigs or ingots in casting machines. Large pieces of alloying materials were required because earlier furnaces lacked automatic material handling and charging systems. The Economy Industrial Gran-Tech Granulation System is a state of the art method of solidifying liquid metal into pellets or granules that are flat or irregular shapes. The granules are between 2-50 mm in size. The customer's material handling systems generally requires granules that are flat and irregular in shape. The Gran-Tech granulation system solidifies, cools, dries, sorts and stores the granules for immediate packaging and shipment to customers.

The Gran-tech Granulation System designed by Economy Industrial an effective granulation machine: it takes about three minutes for the liquid metal (1600, 1630 - 1650 C) in the ladle to reach the storage bins at the end of the system, dried and ready to be packaged.

Since the melting time of granules are shorter, the production costs are generally reduced when granules are used within most melting processes in the metallurgical industry. Granules also reduces handling costs. The granulated product is easy to handle, transport and store. Granules are suited for most types of material handling feeders.

There are many areas where granules can be used in steel-works and foundries. Stainless steel-making converters are in need of strict temperature control during the production process. Materials that are used to cool the liquid metal have to be added to the converter during the decarburizing stage of the process. Granules are particularly well suited to allow for a continuous addition. During such addition, the blowing stage can continue undisturbed and this will increase the productivity of stainless steel-making converters. As a result, the refractory wear is reduced, the chromium yield is increased and ideal temperatures can be achieved.
