Features of the Model 4:
Shearing Action: The four adjustable hard tool steel knives are bolted to a removable rotor. These knives work against six stationary knives bolted into the frame. The shearing action tends to avoid changes in the sample due such temperature rise, moisture loss, liquefaction, contamination, etc. caused by crushing and abrasion methods. The clearance of opposing knives is precisely adjusted for shearing clearance. Each stationary knife is independently adjustable. The fan effect of knives provides increased through-put and quick clearing of the chamber.
Grinding Chamber: The steel chamber measures 197 mm inside diameter x 76 mm deep. The hinged, heavy steel plate door provides full access to the chamber for cleaning. The clamping bolt with handwheel seals door against mill face. The neoprene shaft seal at rear of chamber prevents lubricant from seeping in while also protecting the ball bearings of the rotor shaft from sample dust.
Knives: The inlaid edges are specially formulated tool steel, tempered and hardened for durability and optimal cutting. Knife body is made of softer steel to absorb shocks and minimize breakage. Stainless steel knives are also available for milling corrosive materials.
Hopper: Steel hopper with enameled exterior finish is mounted to the top of grinding chamber with two thumbscrews. Capacity is approximately 550 mL. Includes a tight-fitting lid. Sliding stainless steel plate at base of hopper controls feeding rate. Dimensions: 41/2” top internal diamter x 21/4” throat internal diameter x 81/2” depth.
Sieves: Stainless steel, curved round-hole screens are shaped to fit against the top of the delivery chute block so that samples cannot enter chute without passing through the screen. The chute block is released by two handwheels for easy interchanging of sieves.
Receivers: Adapter chutes slide into a spring-loaded holder beneath the chute block to collect product in a glass jar or stainless steel beaker. The two chutes included with the mill can be interchanged without opening mill door. Clearance below chute is 140 mm to base of bench models, permitting the use of standard receivers even if mill is placed back from edge of bench. Clearance below chute of stand mounted mills is 495 mm.
Jar Chute: Threaded to take standard Mason glass jars, up to 2 qt. (1.8 L) capacity. Jars permit observation of finished product, as well as affording convenience for storage of samples. A bag or sack can be tied on in place of the jar.
Beaker Chute: 105 mm i.d. x 146 mm deep, without spout. Spring-loaded runners hold turned rim of beaker securely against adapter plate to prevent sample loss, while allowing easy removal of beaker. Takes 1,200 mL stainless steel beaker (1527C25).
Drive Unit: Mounted in enameled steel housing directly behind the grinding chamber. Motor is a 1 hp, continuous duty, enclosed ball-bearing type, equipped with thermal overload cutout and needing no lubrication for years. Safety switch prevents operation when the chamber is open. Provides rotor speed of 800 rpm at 60 Hz and 667 rpm at 50 Hz. Pulley drive uses a 16 mm V-belt. Rotor shaft ball bearings require lubrication by means of grease gun included with mill.
For Bench Mounting
Provided with four mounting lugs for bolting to bench, or for attachment of 3375E90 Runners (not supplied)
Includes jar and beaker chutes, three sieves (1/2, 1 and 2 mm), one stainless steel beaker(1527C25), three 1 pint (0.47 L) glass jars (6176B12), set of wrenches, one grease gun and 1 lb. (0.45 kg) of grease.
Overall dimensions 15" W x 24"D x 28"H (381 x 610 x 711 mm); shipping weight: 375 lbs. (170 kg); net weight: 301 lbs. (136.5 kg). Units require 8.4 amps on 115 V, 4.2 amps on 230 V. For replacement belt see Thomas number 3376T80.
