U-1720 Jaw Crusher 2x2 (50x50mm)

Crushers and Pulverizers

We believe that most crushers and pulverizers offered for laboratory use are larger and more expensive than actually needed. We have selected the following small crusher and pulverizer. These require very little table space and are excellent when small to moderate processing is required. Crushing breakage can only be accomplished on fracturable material.

U-1720 Jaw Crusher 2x2" (50x50mm)

This small bench top crusher with a jaw opening of 2x2" (50.8x50.8mm) will process up to 20 lb (9kg) of minus 1" rock to minus 0.125" (3.2mm) in less than 1 hour. This is an ideal machine when only a few samples are to be crushed on an intermittent basis. The discharge opening can be adjusted to yield a smaller product. Jaw and cheek plate are hardened tool steel. Alumina and tungsten carbide plates are available as an option. Dimensions are 10x10x20" (254x254x508mm). Crusher includes base, guard and motor for 115/1/60. For 230/1/50, specify U-1720-3.
Shipping Weight: 50 lb (23kg); 2 cu. ft.

U-1730 All Purpose Pulverizer

This is a perfect companion apparatus to U-1720 crusher. It will pulverize most dry substances up to 0.25" (6.35mm) in any degree of hardness without damaging the molecular structure. Reductions of small quantities can be quickly produced in 1 operation at very low cost. Material is fed through the funnel intake at the top with suction and gravity taking it to the impact area of 18 hammers rotating at high speed which quickly pulverize the material, discharging it through the screen into a bag attached at the bottom of the chute to reduce dust contamination.

6 stainless steel screens with perforations ranging from 0.008 to 0.05" (0.2 to 1.27mm) opening are supplied. Changing screens is a matter of seconds by removing the hammer chamber plate held by 3 large wing nuts. Other size screens are available to special order. Mounting space required is 13x6" (330x152mm). 115VAC is standard; for 230VAC, specify U-1730-3. Motor is 0.5 HP.
Shipping Weight: 66 lb (30kg); 1.5 cu. ft.
