Kek Mills & Grinders

Kek Kibbler Pre-Breakers

Particle Size Range 150mm to 2-3mm (6” to 1/10”)

Designed to grind large lumps up to 150mm (6”), reducing them down to 2-3mm (1/10”), the heavy-duty and robust Kek Kibbler prepares the materials for further processing. Working in conjunction with other Kek mills, or as a stand-alone grinder, the Kek Kibblers are pre-breaker grinding mills also known as de-lumpers and product conditioners. The slow speed, high torque heavy-duty beater bars sweep materials against the contoured grinding screen, causing a combination of crushing impact, cutting, and abrasion, allowing size reduction to take place. The cantilevered shaft grinding beater bars make the Kibbler ideal for pharmaceuticals, food, and fine chemical applications. 

  • Cantilevered shaft
  • High torque performance
  • Low speed, dust, noise, and heat
  • Rapid strip-down and reassembly



Kek Cone Mills

Particle Size Range D50 - 500μ to < 250μ

Recognized as an intermediate energy grinding mill, the Kek Cone Mill is one of the most versatile conical particle size reduction machines in the powder processing industry. The Kek Cone Mill is ideal for sizing in both wet and dry granulation processes because of its ability to take a wide range of feed material and produce an equally wide range of product. Traditional milling problems such as noise, dust, and heat generation, are eliminated due to the Kek Cone Mill’s gentle, low-energy size reduction technology. 

  • Highly efficiency, gentle grinding
  • Low dust, noise, and heat
  • Ideal for fatty, heat sensitive, moist products
Gardner Double Cone Blenders

Gardner Double Cone Blenders for powder processing provide superior blending of free-flowing powders and granules. They incorporate a gentle, low energy tumbling action, ideal for blending the most delicate and fragile products, through to the effective mix of very heavy and abrasive products.
