Ring and Puck Mill is also known as a 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 securely by a cam lever system, and a protective cover encloses the grinding chamber for safe and quiet operation. Wet or dry samples of 0.5in (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 250ml sample capacity 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.
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.
