Hammer Milling

Elcan finds screening solutions to problems that other companies cannot. Find out why we have earned the nickname, “The Screening Experts.”

Our industrial milling capabilities allow companies to convert coarse fractions down to finer particle sizes. Particle size reduction of feed materials by hammer mills occurs in three actions: repeated high-speed impact from hardened steel rotating hammers, materials colliding with the grinding chamber/liner wall, and high-speed particle-to-particle collision (impact and shearing). We have experience working with multiple, friable products that in conjunction with our advanced sieves allow for precise particle size control.

The ability to mill products down to a fine size and then classify then to remove any oversize or fines from the products allows companies to obtain products from material that may have previously been unusable. The hammer milling equipment is great for a wide array of products, including graphite, minerals, and specialty chemicals. Working closely with customers, Elcan often times will sieve products first to maximize yield of good product and then mill the oversize down and reclassify it. This allows for customers to obtain a very high product recovery and significantly decreases the amount of “out of spec” product. The hammer mill works with a sieve to control the particle size inside the system which can ensure that no oversized ends up in the product fraction and significantly lowers any yield loss.

Screens, set at a specified cut point, retain coarse particles for further grinding while allowing product sizes below the cut point to pass and exit the mill. Achieving the target particle sizing is a function of rotor speed, feed rate, hit resistance, clearance between grinding plates and hammers, and screen size.

Features & Benefits

  • Milling is perfect for producing individual pieces in small or large batches
  • It has the capability of producing complicated shapes, using multi-tooth and single point cutting tools
  • The operation costs can be controlled to a great extent if general-purpose cutters and equipment are used
  • Greater precision in the finishing of the work compared to other machines
