SMD-504 (СМД-504) single-rotor hammer crusher

Single-rotor hammer crusher SMD-504 (СМД-504) is designated to crush brittle and soft materials: coal, rock-salt, chalk, gypsum, crushed bricks, fire-resistive rocks, potassium aluminium sulphate, saltpetre, limestone, some ores and other low-abrasive materials with humidity at which choking-up of grizzly feeders does not take place.

With grizzly feeders taken-off the crusher may be used to crush materials with increased humidity.

Crushers of this type are distinguished by high breaking degree, performance, low power consumption, simplicity of construction.

Various materials are crushed with the use of hammers which are hinged on the rotor. Material is fed through the feed inlet to crusher body. When the rotor rotates material gets milled. The ground substance is sieved through grizzly feeder downwards.

Breaking hammers are fabricated of manganese steel 110Г13Л. In order to reduce a possibility to stuck slots between bars grates are arranged at an angle of 45 degrees with respect to rotor radius towards material protraction.  Bars are fabricated of steel 110Г13Л as well.
