Recyclinginstead of disposal

KOMINEX Minerals + Processing processes your industrial mineral residues. We can offer you customised concepts for your residues using our years of experience and broad know-how in recycling industrial minerals.

The focus of our activities lies in the recycling of garnet sand from water jet cutting and scrap material from the manufacture of vitrified grinding tools and refractory products.

In addition to processing mineral residue, we are also able to offer you high-quality virgin garnet sand due to our many years of experience. We can be your fully integrated partner for all garnet sand needs.

Production processes

On six production lines, residual minerals from the abrasives and refractory industries are made into high-quality products at KOMINEX Minerals + Processing.

Our systems include:

  • Different crushers
  • Various mills
  • Several drying furnaces
  • A variety of magnetic separators and de-dusting equipment
  • Complex sieving equipment to produce various grit sizes

Testing laboratory

The quality of raw materials is decisive to improving final products and recycling processes. In a first step, we inspect your residues individually for their general suitability for recycling and discuss the best methods to transfer your materials to us.

Upon arrival of all residual materials in our facility, these are again inspected for adherence to the needed parameters for smooth processing. Then they are stored for the interim, and in due time fed into the recycling process in order to manufacture the desired final product.

Before the final products are shipped to our customers, they are inspected in our in-house laboratory for precise adherence to all physical parameters and then shipped.

Our quality assurance consists of the following (among other things):

  • Detailed discussion and close cooperation with our residue suppliers
  • Physical analyses of materials in our in-house testing laboratory
  • Continuous feedback about our product quality

European certification

KOMINEX Minerals + Processing is certified according to EMAS, which underlines our obligation to our customers. Furthermore, we are a certified waste management facility, and have all needed permits for professional acceptance and processing or disposal of your residual materials.
