jaw crusher

Description   Jaw crusher is mainly used for crushing a variety of ores and medium-grained bulk materials. It can crush available materials with compressive strength no more than 320Mpa, divided into rough crusher and fine crusher. This series of jaw crushing products specification is complete, the feed particle size of 125mm ~ 750mm, is the preferred equipment of primary crushing.

   The machine composed by the fixed jaw plate, movable jaw plate, side plate retaining plate elbow pad elbow pad bracket to adjust the spring seat belt motor track flywheel eccentric shaft pulley rack composed of fixed jaw

Characteristics of coarse crusher1, crushing cavity symmetrical "V"-shaped structure, making the actual feed mouth width and the notional feed mouth width consistent.2, the latest use of the tooth guard, and increases the effective length of the jaw, higher yields.3, bearing using integrated steel structure. Overall steel bearing frame to ensure full cooperation with the crushing, but also greatly enhances the strength of the radial bearing, while the split bearing without this advantage.4, using the finite element analysis techniques, rough jaw crushing machine has a higher strength.5, using world-class manufacturing processes, selection of the most high-end production of materials.6, the discharge opening to adjust more quickly and conveniently. European version of the JC series of rough jaw crushing machine equipped with a wedge nesting population adjustment device, which is simpler, safer and faster adjustments than the old gasket.7, the choice of bearing size larger, higher carrying capacity. All JC series of rough jaw crushing machines are equipped with the same specifications than the other larger and more durable coarse crusher eccentric shaft bearings, the higher carrying capacity and effective labyrinth seal to greatly extend bearing life8, more advanced movable jaw assembly to make it more durable. Movable jaw assembly adopts high-quality cast steel structure, and transmission via two large steel flywheel. In addition, the use of heavy eccentric shaft is also forging processing, All of this makes the JC series of jaw-type crushing machine with exceptional reliability.

ApplicationThis series of crusher is mainly used in fields such as mine, metallurgy, building material, chemical industry and hydropower, etc. It is used to crush primary materials with compressive strength less than 320mpa.

Working principle of rough jaw crusher     Coarse crusher - jaw crusher crushing work for the song move extreme-pressure, and its working principle is: the motor rotation, through the V-belt, pulley drives the eccentric shaft, the jaw has been adjusted in accordance with good track exercise, activities of the jaw also on the fixed jaw plate for the swing back and forth periodically, when the jaw plate close to, the material between the two jaw plates are squeezed, splitting and bending broken, when the jaw plate leaves, crushing cavity is less than the lower part has been broken into nesting population of the material, automatically fall by its own weight, the material is located in the upper part of the crushing chamber, has not yet broken to less than the nesting population size, but with the decline in nesting some distance, until the moving jaw again by pressing the fixed jaw plate.
