Stedman's line of fabricated hammer mills for crushing, grinding and pulverizing includes Type "A", "B" and "BX" Hammer Mill models and features a more competitive cost and lighter weight than previous Stedman hammer mills that were all cast. Hammer mills operate with a rain of hammer or ring blows to shatter and disintegrate materials, require less maintenance and allow for easy access for adjustments and replacements. Hammer mills are available for a variety of size reduction applications, including alum cake, bran, coal, fish scrap, gypsum, limestone, shelled corn, steamed bone, wood, dried milk, oats, salt cake and animal tankage. Type "A" Hammer Mills (up-running) feature a 2-stage reduction principle for a dual mechanical reduction using the revolving hammers to shatter materials upon entry and then further disintegrating materials against the breaker plates. Type "B" Heavy Duty Hammer Mills use heavy, reversible hammers in conjunction with Stedman's exclusive saw-tooth breaker plate to produce uniform product. Type "BX" Medium-Duty Hammer Mills, similar to Type "B", feature a larger feed opening for medium hard, lumpy or bulky materials. Both the "B" and "BX" are down running hammer mills.
