KEFID DR-Series VSI crushers are operating in aggregate and mineral processing installations around the world with an established track record of cost savings, durability and unmatched performance. KEFID has the technology and experience in applying and servicing the DR-Series VSI across the globe in an extensive variety of applications, processing a diverse range of materials.

The unmatched producer of superior concrete and asphalt aggregate
Less cement can be used and stronger concrete created by using KEFID DR-Series VSI product. The KEFID DR-Series VSI combines high velocity impact crushing with high pressure attrition grinding to produce high volumes of cubically shaped product. Continuous control of the product shape and gradation provides a product which meets the size distribution required.

A proven producer of quality manufactured sand
Superior particle shape and consistent gradation are a direct result of the rock-on-rock principle of the VSI crusher. Impact, grinding and abrading within the crusher simulates the action of nature, eroding the particles to a cubical shape.

The perfect pre-mill crusher to improve mill circuit performance
The KEFID DR-Series VSI reduces power requirements and increases mill capacity by reducing the top size and increasing the fineness of the mill feed. Mill liner life is increased by providing a finer mill feed, allowing the use of smaller mill balls to achieve the required size reduction.

The producer of fine products for the industrial minerals industry
The KEFID DR-Series VSI's crushing action gives a product with a large surface area, which gives increased recovery of the desired mineral. The free impact reduction will preferentially crush a more friable mineral when separating a desirable product from a waste material.

The only viable crusher for extremely abrasive fine material
The rock-on-rock crushing principle of the KEFID DR-Series VSI minimises metallic wear resulting in low maintenance and wear costs. The low wear of internal components ensures extremely low contamination of fine products by wearing metal parts. KEFID DR-Series VSI crushers process a diverse range of materials in applications across the globe. The KEFID DR-Series VSI is a producer of superior shaped product.
