40 • ROCK products • March 2019 Crushing Stedman Cage Mills Stedman multi-row cage mills pulverize, grind, crush and/or mix abrasive and non-abrasive materials – wet, sticky or dry. The cage mills offer: • Fine, uniform grind up to 240 tph. • Reversible for extended wear life. •  Single-, two-, four-, or six-row cage assemblies are available. • Optional heaters and air cannons are available to reduce buildup of wet and sticky materials. •  A quick-opening housing provides minimum downtime during maintenance. •  Cage inspection requires about five minutes, complete change-out in as little as one hour. •  Aglime, coal, fertilizer, salts, potash, corn, aluminum dross, grains and gelatin applications. • Full-scale toll processing and testing available. Stedman Machine Co., McLanahan MSP Cone Crushers The technology that makes a McLanahan MSP Cone Crusher outperform competitive cones on the market is the com- bination of all of the factors of performance i.e. balanced eccentric, higher speeds, fulcrum point position, and stroke. By using sound engineering with years of field testing a truly tried and tested new cone crusher has emerged. A balanced eccentric coupled with a fulcrum point ideally placed over the crushing chamber yields highly effective compression crushing. This allows higher eccentric speeds to maximize performance without disruptive forces. The eccentric stroke is designed to work with the eccentric speed and fulcrum position to produce higher yields and minimize recirculating loads. The torque and resultant crushing forces are as effective as virtually any cone crusher on the market. Spiral bevel gears provide the turning force to the eccentric. The spiral gear is mounted on a sturdy countershaft of the cone crusher, which rides in bronze bushings. The gears are precision cut for quiet operation. Misalignment problems are eliminated. The MSP Cone Crusher features one of the largest volume dis- placements by a crusher head. When there is a large volume of material displaced this way, it means that more material is crushed in each cycle, more material can be fed to fill the larger void left when the crushing head recedes, and more material flows through the crusher due to the larger through- put and gyrating cycles allowing material to drop further. The benefits of high efficiency, greater crushing force and high capacity coupled with the durability the market expects are the reasons why this design is the best way to increase your productivity and profitability. MSP Cone Crushers are built to make operations run smoother and easier. It's simple control panel provides users with the necessary information to properly run the crusher. For example, the MSP Cone Crusher shows the exact cone set- ting to allow the operator to stay on top of a critical set point. McLanahan Corp.,
