Indepth Knowledge Of Hammer Crusher

Hammer crusher is a common crushing equipment and widely used in mine machinery industry . Its common fault basically has the following kinds: bearing overheating ,reduce yield, elastic joints produce knock, the grain-size is too big,machine generated internally knock, etc.Now we detailed look at these faults and solutions.

One . Bearing overheating fault phenomena

Reasons: 1. Bearing damage, 2 insufficient ,3. Grease grease uncleanness metamorphic ,4. Too much grease .

Solution: 1.Replace bearings , 2. Bearings embellish fat should be 50% of its space volume ,3. Cleaning bearing , replace the grease 4. Refill moderate grease.

Two.Reduce yield fault phenomena

Reason: 1. Sieve the aperture be blocked , 2.Charging uneven .

Solution: 1. Parking, cleaning the blockage crack in the screen, 2. Adjust charging institutions.

Three:Elastic joints produce knock fault phenomena

Reason: 1. Elastic ring wear, 2. Pin shaft is loose .

Solution: 1. Replace elastic lap, 2. Parking and screw down pin shaft nut .

Four:Machine generated internally knock Fault phenomena

Reason: 1. Foils fasteners relaxation, hammer the impact on lining board. 2. The broken objects into the machines internal , 3. hammer or other parts fracture .

Solution: 1.Check the fastening lining board and the hammer with screen; the gap between ,Disc feeder,2. The parking, cleaning the crushing cavity, 3. Replace fracture parts .



Mining Machinery Exist Two issues in China


At Present ,There are two aspects of the problem of our country mining machinery industry .

1.The comprehensive strength of the mine machinery industry enterprise is not strong,most enterprises energy and funds are at standstill in scientific research,new product development, technical innovation and enterprise management aspects etc.

2.Varieties of products,technology,rod mill,quality,service and other problems,lead to the actural contribution rate is low of domestic mining machinery industries.

To solve the problem,firstly, mining machinery industry should establish different forms of joint with foreign companies and domestic professional designing institute.

Secondly,establish and perfect the advantage specialized applications laboratory,applied technology research of products and manufacturing process.

In addition,take different forms of joint and cooperation with the domestic and foreign related institutions of higher learning.


Throughout the history of domestic mining machinery,our country mining machinery industry in the 1990s are the most difficult times.Mining machinery industry began to recover after 2000,the enterprise get out of predicament of losses,welcome the development of historic opportunity.But our country ore machine industry technology foundation is weak at present,since the reform and opening,mining machinery industry as the main way of improve the product technical level by use taking market change technology,also face the grim situation of foreign competitors invest in China at the same time.Concerned expert advise,if our country mining machinery industry want to seize the opportunity,accelerated development,we should play up in the scientific research and techinical improvement and innovation firstly
