3" x 4" Laboratory Jaw Crusher - 220V, Single-Phase, 50/60Hz

3" Maximum Feed Size – Reduces aggregate and rock material up to 3" for laboratory sample preparation. 1/4" Typical Product Size – Produces material with approximately 50% passing a 1/4" (6.3 mm) sieve. Adjustable Jaw Opening – Quickly adjusts from 0.375" to 1.5" (9.5–38 mm) to accommodate different crushing requirements. Variable-Speed Operation – Overhead eccentric is controlled up to 375 RPM for efficient, controlled crushing. High Throughput – Processes up to 500 lb (226.8 kg) per hour for most materials. Long-Life Jaw Plates – High-manganese steel jaw plates can be rotated when worn, extending service life and reducing replacement costs. Ideal for Sample Preparation – Quickly prepares aggregate and rock for final laboratory testing or secondary crushing. Electrical Requirements – Operates on 220V, 50/60 Hz power supplies. Features: Adjustable crushing jaws control output size Economic performance with lower dust output High operating rpm offers efficiency in size reduction Base frame is constructed of welded steel Included Items: 2.25" x 3", or 3" x 4" Laboratory Jaw Crusher (115V, 50/60hz or 220V, 50/60Hz) Power cord and plug
