Comparison of advantages of jaw crusher and hammer crusher

Crushing effect

Jaw crusher crushes the stone material through the extrusion of two jaws, and the discharged finished product has more needles and flattened stones, and the discharged material has a larger particle size.

Hammer crusher is through the high-speed rotation of the hammer will stone material into slag, and the discharge port is also set up with grates shaping, the discharge of the finished product in the pin flake less, the particle size is more complete, the particle size is more uniform, can be used as a finished sand and gravel.

Crushing range

Jaw crusher can crush all kinds of high hardness ores, medium hardness ores (compressive strength between 300-350Mpa), hard such as granite, basalt, cobblestone, pyroxene, gold ore, iron ore, etc., and general hardness of limestone, calcite, gangue, dolomite, bauxite, etc. can be crushed, the size of the feed ≤ 1200mm, the range of discharged material in the 10-350mm arbitrary adjustment. 350mm adjustable.

Hammer crusher is not suitable for high hardness stone crushing (compressive strength is generally lower than 200Mpa), commonly used in limestone, gypsum, coal, calcium stone and other medium hardness stone crushing, feed size ≤ 1000mm, discharge range can be adjusted between 0-60mm.

Crushing capacity

Jaw crusher for stone crushing, the output range of 1-1590t/h, and crushing larger materials, usually the discharge can not be used as a finished product, need to be secondary crushing process.

Hammer crusher for stone processing, output range of 100-3000t/h, and the equipment can be a molding, set of coarse crushing in fine crushing as a whole, without secondary crushing finishing.

Jaw Crusher and Hammer Crusher are commonly used in the production line of sand and gravel aggregates, simple structure, easy to use, so when should we use the jaw crusher, when should we use the hammer crusher?

1, look at the hardness of the material: large hard rock crushing on the jaw crusher, large hard stone crushing on the jaw and hammer crusher which cost-effective.

2, look at the requirements of the finished product: jaw crusher usually with the impact crusher, impact crusher and so on to form a set of gravel production line, so the finished product requirements of high with the jaw crusher, the quality of the finished product requirements of the general requirements of the hammer crusher can be considered.
