The Hammermill Coal Crusher processes feed sizes up to 2in (51mm) at a maximum rate of about 1,000lb (454kg) of coal material per hour. Final size is down to approximately 1/16in (1.6mm) Rotor speed is 3,450rpm. Covered Feed Hopper capacity is 0.40ft3 (11.3L), and crushing chamber is 7x6in (178x152mm). Includes a choice of two screen plates in sizes 1/16, 3/32, 1/8, 3/16, 1/4, 3/8, or 1/2in (1.6, 2.4, 3.2, 4.8, 6.4, 9.6, or 12.7mm), specify when ordering. Inquire to purchase other sizes separately. Also included are two sample collection containers with approximately 10lb (4.5kg) and 35lb (16kg) coal capacity, and 10ft (3m) of four-conductor, rubber-covered cable for connection to a power source. Powered by a 2hp TEFC motor.
The Hammermill Coal Crusher has a rotor-swing hammer, enclosed case, covered feed hopper, and cast iron housing. Housing is hinged and latched for quick access to the grinding chamber for cleaning and replacement of the bolted-in screens. For safety, an open-latch sensor cuts all power and must be reset before re-starting the machine. Rotor, swing hammer, and screen plate larger than 3/16in (4.8mm) are heat-treated and hardened, and rotors are reversible end-for-end for maximum hammer life. Feed hopper gates allow manual feed control. Spring-loaded clamps securely seal the sample collection containers to discharge spouts to control dust during crushing. Two Screen Plates with round perforations are included, and size must be specified at time of order. Additional screens are available as noted. Unit is mounted on four casters for easy relocation in the lab. A special control box with NEMA 12 magnetic starter and over-load protection is standard. Standard wiring is 230V/60Hz, 3 phase, but a number of different configurations, including explosion-proof options, are available. Inquire for more information.
