Wescone W300-3

The new 2015 Wescone 300-3 supersedes the 22 year old W300/2 high speed cone crusher.

The W300-3 new and improved model has been introduced in Australia and now is available from Heath & Sherwood.

Early in 2013 the team at Wescone decided to take a closer look at a number of potential improvements which could be made to the W300/2. Through the use of Finite Element Analysis of all design components in the old model W300/2 were researched to make available improvements which will help performance. The Wescone project lasted for 2 years and was based around observing the results over decades of servicing, analyzing wear parts and making less obvious material and/or mechanical changes within the machine. The results according to Wescone was a “great insight into component selection and material designs”.

The new machine design can be straight swapped for the old machine (same external and base dimensions) with the amazing improvement +25% crushing efficiency and power reduction of similar at -25%. The W300/3 machine’s body is more robust as weight has increased around +5% ( about 10kg ) but at least 80% of the new parts by weight, are not interchangeable with the W300/2.

The W300-3 gives more crushing efficency with less horse power!

  • Portable more efficient than the original.
  • World's smallest gyratory crusher (265 Kg).
  • All minerals crushing for rapid sampling.
  • Glass recycling and crushing machine.
  • Best reduction ratio available in a single pass. Maximum Reduction Ratio: 25>1
  • Best gyratory crushing action for maximum efficiency.
  • Feed Maximum Size 50mm (33mm F80)
  • Discharge Minimum Closed Side Gap Setting 2mm
  • Recommended 9.2 kW (12.5 hp)
  • Designed, developed and manufactured in Australia, for the harshest mining regions.
  • More than 300 units used in over 20 countries, can be straight swapped with the original W300/2.
  • Heath & Sherwood will continue to service and repair all W300/2 machines in operation.
