Metal Briquette Machine Guideline

Why make metal briquette

Traditional maching process, due to imperfect technology, designers design products in the processing of a large number of iron chips, steel swarf, copper swarf, etc., in order to save costs and reduce waste and environmental protection, the recycling of the waste chips is of great significance.

With the development of global industry, the demand for steel has increased significantly, and a large number of metal chips are inevitable in the production process. Many factories do not pay enough attention to the treatment of metal chips, so many of them will accumulate. These chips, like iron waste, when exposed to the natural environment, will be easy to be corroded, the corrosion of iron filings reuse processing process is more complicated, and waste a lot of energy.

The amount of these metal chips are very large, their shape leads to occupying a lot of space when stored. During the processing such chips will be stained with a large amount of oil and coolant, simple processing will cause debris to scatter, and a certain amount of waste chips by briquetting to form a briquette that is convenient for storage management, which is more space-saving in the storage of these swarves, but also plays a certain protective role, reduces environmental pollution, and reduces unnecessary complex processes when reusing.

What is a metal briquette machine

Metal briquette machine presses the metal waste under high pressure into a briquette form. Normally it is used to reduce the storage cost as well as the conversion ratio in the furnace for metal recycling. The study shows the energy cost to get metal from metal recycling is only 50-90% by using raw minerals. Also, this will help to reduce the exhaust on the metal manufacturing process.

Energy consumption from recycling compare to use raw mineral

  • Zin 62%
  • Pb 73%
The raw material cost takes about 60% in the foundry industry. If you want to own a positive market competitiveness under the same foundry technology, you must find cheaper material, the metal chips is a good substitution. And the briquetting metal brings more economic than directly use metal chips for smelting.  Take iron as an example, the chips’ value amounts tens of the briquette, so the oxidation ratio is very high and easy to be blown away by the strong wind in the furnace, total the waste ratio is nearly 30%, but if use the briquette, the waste rate is only 5%. this means the metal chips after compress to be briquette, can improve 25% user ratio.

Common metal waste

Aluminium swarf/chips, Cast Iron swarf/chips, Copper swarf/chips, Steel swarf/chips, Stainless Steel swarf/chips, Brass swarf/chips, Titanium swarf/chips,  Nickel swarf/chips, etc.

Material – where the metal waste usually comes from

  • Scrapped machinery, equipment, metal parts.
  • Cutting waste, scrap.
  • Discarded metal products in daily life.
  • Non-ferrous metal smelting waste, such as iron oxide skin (mill scale), slag, smoke dust.

The raw metal chips requirement


No requirement on the moisture. There’s no need to worry if your metal chips if with coolants, actually, the metal briquette machine squeezes out harmful coolants from metal shaving, expel up to 99% moisture from the bulk materials.


The feeding size is very important for the briquetting process no matter what kind of briquetter you are using. Small particles very help to make high-quality briquette, with consideration of feeding section and the briquette quality, raw metal chips with size under 30mm is much acceptable.

Use a hydraulic briquetting to briquette the metal chips

The hydraulic briquetting system has a much larger briquette force than other types of briquette machine, long pressure holding time further makes the briquette perfect.

Work with the hydraulic briquetting machine  to compacting your scrap metal, improve your bottom line and reduce waste from industrial turnings, filings, chips, clippings and even metallic dust.

The benefit of making metal briquette

  • Briquetting increases the value of you metal chips and turns them into an ongoing income stream.
  • Briquetted material helps alleviate any potential cross contamination with other materials.
  • Briquettes are almost free of CNC coolant compared with loose metal chips and don’t leak coolant during transportation around the factory or en route to the recycler.
  • Briquetters eliminate the need for drying racks or centrifugal dryers, removing a costly handling process.
  • Transportation, handling and storage costs are lowered as a result of the volume reduction achieved through briquetting.
  • Machine briquette counters allow you to accurately monitor the amount of scrap being produced.
  • Briquetting your swarf allows a substantially more localised and tidy storage of your scrap, thus reducing your occupational health and safety risks.

DRI has ways to deal with including use the hydraulic briquetting system, big silos supplies buffer for final feeding, make the system with single structure, easy for operation.
