Small Holmes Hammermill Coal Crusher

Small Holmes Hammermill Coal Crusher

The Holmes Hammermill Coal Crusher, specifically the small model, is engineered for efficient and safe reduction of bulk coal and coke samples. Designed for laboratories, it features rotary-swing hammers within an enclosed case and covered feed hoppers, ensuring both user safety and operational cleanliness. Its robust cast iron housing promises low maintenance and a long service life.

Key Features & Performance:

• Sample Reduction: Effectively crushes samples up to 2in (51mm) down to a final particle size of approximately 1/16in (1.6mm).
• High Throughput: Processes coal material at a maximum rate of 1,000lb (454kg) per hour.
• Safety First: Equipped with hinged and latched housings that include an open-latch sensor, automatically cutting power for maximum user safety during operation.
• Durability: Rotors, swing hammers, and screen plates (larger than 3/16in/4.8mm) are heat-treated and hardened to ensure exceptional wear resistance and extended service life. The rotor assembly is end-to-end reversible, further maximizing hammer life.
• Ease of Use & Maintenance: Hinged housings provide quick access to the grinding chamber for cleaning and screen replacement. Hopper gates allow precise manual feed control.
• Dust Control: Spring-loaded clamps secure sample collection containers to the discharge spouts, effectively minimizing dust emissions during crushing.
• Portability: Mounted on four casters for easy repositioning within the lab.
• Power & Control: Operates on 230V/60Hz, 3-phase power, powered by a 2hp TEFC motor with a standard rotor speed of 3,450rpm. Includes a dedicated control box with NEMA 12 magnetic starter and overload protection.

Included & Optional Items:

• Standard Screens: Comes with two screen plates, 3/16in (4.8mm) and 1/16in (1.6mm), with round-hole perforations.
• Expandable Options: Additional screen plates are available for purchase in various opening diameters: 1/16, 3/32, 1/8, 3/16, 1/4, 3/8, and 1/2in (1.6, 2.4, 3.2, 4.8, 6.3, 9.5, and 12.7mm).
• Accessories: Includes two sample collection containers (10lb/4.5kg and 35lb/16kg capacity) and a 10ft (3m) power connection cable.
