The Vibrating Cup Pulverizer is also known as a puck mill or shatterbox. This pulverizer efficiently uses pressure, impact and friction to grind rock, ore, minerals, soil, and other materials to analytical size. It has many useful applications in the laboratory and small-scale pilot plants. An 8in (203mm) diameter bowl containing grinding rings and a puck is driven by a rotating eccentric and swings contents on a horizontal plane at a precise speed and distance for maximum grinding efficiency. The grinding bowl is locked down and held securely in-place by a cam lever system, and a protective cover encloses the grinding chamber for safe and quiet operation. Wet or dry samples of 1/2in (12.7mm) maximum feed size are rapidly reduced to a final particle size of 150—38µm (No.100 to No.400 U.S. Standard sieve size), depending on material.
The included chrome-steel alloy Grinding Set has a sample volume of 250ml and consists of an 8in (203mm) bowl with cover, two rings and a puck. For more efficient processing, additional Grinding Sets can be ordered as LCA-240. LCA-242 Tungsten Carbide Grinding Set with 100ml capacity is also available. Inquire for expert advice on applications for this unit. The heavy-duty 1hp motor includes a starting switch and drives the eccentric at a speed of 900rpm (750rpm at 50Hz). The control panel is set at the proper angle and height for best visibility and ease of operation. A 0-100 minute digital timer resets itself automatically after each test for maximum repeatability. An emergency stop button is provided. Sturdy painted-steel insulated cabinet reduces noise. The motor operates on 208/220/400V, 50/60Hz, three phase power supplies. Single phase available as well.
