Centrifugal Impact Mills

Fine grinding made easy: No screens â cleaning made easy â controllable results OVERVIEW Ideal for: Fine grinding of friable materials Coarse grinding friable materials Lump breaking Conditioning of cellulose fibers Wet or dry materials Tight particle size control Finally, a mill that gives controllable particle size distribution and is easy to clean. The versatile Munson Centrifugal Impact Mill provides a simple, inexpensive means of grinding, sizing, de-agglomerating and homogenizing material, and can be employed as an effective infestation destroyer. It yields particle sizes down to 325 mesh and is primarily used for friable materials. Available in #304 stainless steel, sanitary, abrasive resistant and standard carbon steel design, the Centrifugal Impact Mill operates without screens, hammers, knives or rolls. Operation Metered material is gravity fed through the centrally located inlet of the "stator disc". Centrifugal forces accelerate the material and launch it into the impact zone. The action created by the stationary and rotating pins creates a "treacherous path" for material to pass through. Achieving the desired tight particle size distribution is obtained by controlling the rotor speed. Varying the rotor speed between a few hundred rpm up to 5400 rpm provides the flexibility to use the machine as a coarse grinding or de-agglomerating unit as well as a fine grinding mill. Whether the machine is used for cracking wheat, grinding iron oxide powder, creating powdered sugar or as a cellulose fiber conditioner, large production throughput rates can be attained in an inexpensive, compact machine. It also fits in neatly after most flaking operations. Disc Attrition Mills also available for fine grinding applications of more fibrous materials down to 100 mesh Lab testing icon

Hammer Mills

The Munson Hammer Mill reduces a broad variety of friable and fibrous materials into very fine products in uniform size ranges from 20 to 300 mesh (versus 50 mesh [250 micron] for some competitive machines). If raw material consists of large pieces exceeding 2" to 3" (50 mm to 75 mm), a pre-crusher may be used ahead of the hammer mill for initial reduction and uniform feeding of small pieces. Engineered for economical operation, extreme durability and low horsepower per ton of output, Munson Hammer Mills also offer compactness, flexibility and ease of operation. Compare Munson's ž inch thick housing with the lightweight gauge-stock housings of competitive machines to understand one of the many reasons why a Munson Hammer Mill offers stiffness, alignment, durability and reliability unmatched by any other brand. Also designed for top efficiency, Munson Hammer Mills have an extra quarter screen located in the hinged section of the top case, increasing screen area by approximately 50% over that of conventional designs, for a total of 270°.

Large Block Shredders

Reduces large blocks and bails of material into particles of narrow size ranges with minimum fines OVERVIEW The "Maxum 30" shredder from Munson reduces large blocks and bails of material into particles of narrow size ranges with minimum fines. Each of two rotors is configured with a staggered array of specially treated, solid carbide tips able to shred a broad variety of materials, including the most difficult-to-shred products. The conical tips have an interference fit into receiver slots for rapid replacement. Driven by two 20 HP (15kW) motors, the counter-rotating shafts can grind blocks of material up to 2 ft x 2 ft x 6 ft (610 x 610 x 3658 mm) in size and 1600 lb (726 kg) in weight, into uniform particles within narrow size ranges determined by the diameter of bed screen perforations which range from 1/32 to 1-1/2 in (0.79 to 38 mm). The two 14 in (355 mm) diameter shafts rotate at 25 to 35 rpm, producing up to 240 cu ft (6.8 cu m) of sized product per hour, depending on material. The cutter handles large pieces of solid material, blocks of frozen products, compounds that cold-flow (such as SB rubber), and highly abrasive products. Material is fed through the top intake chute and discharge is via gravity, pneumatic transition or independently powered belt or screw conveyor. The unit is equipped as standard with two direct-coupled shaft-mounted gear reducers. Operating Mechanism Dual shaft Dual rotor Dual rotor very low speed high torque

SCC Magnum Cutters

A specialized Screen Classifying Cutter for large-scale applications OVERVIEW Munson's SCC Magnum Cutter is an ultra heavy-duty version of the SCC Cutter, itself an exceptionally rugged machine. While the SCC Magnum Cutter handles the same types of materials as the SCC cutter, its extremely robust design enables it to accommodate infeed of significantly larger sizes, and achieve much higher rates with ease. In other regards, the SCC Magnum Cutter offers the same design and production advantages of Standard SCC Cutters: minimal power requirements, patented rotary cutter design, non-redundant cutting, spiral feeding, stationary bedknives, bedscreens, infeed and discharge options, drive arrangement options and construction/finishes to industrial or sanitary standards.

SCC Screen Classifying Cutters

The Munson "SCC" Screen Classifying Cutter is highly effective at cutting hard, soft and fibrous materials into controlled particle sizes with minimal fines at high rates. It features a patented helical rotor design with dozens of cutter blades attached to a helical array of staggered holders called "interconnected parallelograms" to continuously shear oversize materials against twin, stationary bed knives. Unlike conventional granulators containing a small number of angled rotor blades that slice materials into strips in scissor-like fashion, the SCC cutter is configured with cutter blades along the entire shaft, with no gaps between blades, making total contact with the product. As a result, the material is cut into uniform pieces with minimum fines or imperfections in the granulate and little to no heat generation. The blades are available in stainless steel, tool steel and tungsten carbide, and are available with replaceable cutter tips that are with retaining socket-head screws for rapid replacement. Primarily employed for coarse grinding of materials into particles of uniform sizes ranging from granules down to 20-30 mesh, the cutter has throat widths ranging from 10 to 72 inches. Bed screen perforations range from 1/32 to 1-1/2-in (0.79 to 38 mm) in diameter and up to 3-in (76 mm) square, according to material characteristics and desired particle size. The 11-in (279 mm) shaft rotates at 30 to 3600 rpm, producing up to 1000 cu. ft. (28 cu. m) of sized product per hour, depending on application. Offered in industrial, abrasion resistant, stainless steel and food-grade construction, the cutter handles fiberglass insulation, potash, herbs and spices, flake materials, chalks, clays, coal, filter cake, sugar, wood chips, foods, foundry materials, grains, minerals, pharmaceuticals, pigments, powdered metals, medical waste, general chemical products and plastics, including scrap from thermoforming, molding and extrusion operations. Material is fed through the top of an adjustable, double-baffled intake chute, or directly into the front of the chute though a hinged door. An independently powered, variable speed pinch roll feeder is offered for horizontal-rolled product feed. Discharge is via gravity, pneumatic transition or independently powered belt or screw conveyor. A multiple V-belt drive motor is standard, and a direct-coupled drive and gear reducer optional.
