Fertilizer Ingredients
Sturtevant Simpactor® Pin Mill
These are a couple examples of how the below features and benefits being applied as a preferred solution for processing fertilizer ingredients effectively and efficiently. Sturtevant has been supplying these types of solutions for over 130 years and invites you to explore our proven solutions. Other fertilizer ingredients/minerals processed are lime, urea, phosphates and more.
How it works: The Sturtevant Simpactor® is a centrifugal, pin-type impact mill. The Simpactor can reduce low-to-medium-density materials to uniform fine particle sizes of 50-200 mesh or take apart feed material components when used at low RPM. Feed is dropped onto the spinning rotor plate where centrifugal force drives it through a set of intermeshing pins and against a corrugated impact ring. This action reduces the size of friable particles via impact, or gently separates the material into fractional parts if used at low RPM.
| Features: |
| |
• The Simpactor® can be supplied in either carbon steel construction or various stainless steel designs.
• Tungsten carbide pins and ceramic impact liners are available for wear protection.
• Zero bug trap and quick change sanitary units are also available.
• Scheduled bearing lubrication can be done from external fittings. Larger models are equipped with a re-circulating temperature controlled oil tank.
• To minimize nuisance dust, and enhance product throughput the discharge cone contains a ventilation tube for connection to a nuisance dust collector.
• There are no screens to blind in the Sturtevant pin mills.
• Pneumatic or gravity feed is possible via a rotary air lock valve or volumetric feed screw. |
| Benefits: |
| |
• Due to the vertical shaft design, the product falls through by gravity eliminating material hanging up inside the mill.
• The range of the product particle size is achieved by simply adjusting the rotor speed.
• The rotor acts like a fan pulling in cool air to prevent excessive heat build up.
• Bearings are mounted in a “cartridge” for easy replacement reducing downtime and maintenance costs. |
