Black Sand 660

It is recommended to add a small amount of white mineral oil or diffusion oil to the raw materials when using small size granules. After wetting the raw materials, mix them thoroughly with it before directly granulating.

For medium size  they can be directly mixed and stirred with the raw materials without additional treatment.

For this product, the usual addition ratio is between 1-2%, but the final amount should be adjusted based on the required blackness of the product.
