Primary Jaw Crusher

Advantages of Primary Jaw Crusher

1.Suitable for crushing of materialswith high hardness;

2.The crushing cavityof primary jaw crusheris deepwithout dead zone, which improves the feeding capacity and output;

3.The structureof primary jaw crusheris reasonable and simple, which makes the feed port and crushing ratio are large;

4.The adjustment device of gasket type discharge opening is reliable and convenient with a wide adjustment range.

5.The lubrication systemof primary jaw crusher plantis safe and reliable, which makes the parts can be replaced easily and the operation cost is low.

Disadvantages of Primary Jaw Crusher

1.The moving jaw of primary jaw crusher is in working stroke between 0-270 degrees and in empty travel between 270-360 degrees， which makes the non productive power consumption is increased, and the load changes rapidly under no load, and the moving jaw is easy to wear.

2. The primary jaw crusher adopts the method of extrusion crushing, which makes the broken material has a lot of needle and flake content and easy to produce over the crushing phenomenon.

3.At present, it is very difficult for primary jaw crusher to achieve fine crushing under the technical conditions, which requires multiple operations.
