The Factors Which Affect Wear Of VSI Crusher Hammer

SHANGHAI SHIBANG MACHINERY CO., LTD is one high-tech enterprise, which involves R&D, production, sales and service as well. In the past 20 years, we devote to producing mining equipments, sand making machines and industrial grinding mills, offering expressway, rail way and water conservancy projects the solution of making high grade sand and matched equipments.

Almost all the materials in SBM VSI crusher’s crushing chamber are moving, which would collision on the crusher’s spare parts. The wear of VSI crusher’s key parts is mainly by impact of feeding materials and the rotor and the friction of rotor and the fine materials which around the rotor. As for hammer, it plays an important role to protect rotor not to be impact by the materials. Here we focus on the factor that effect the hammer wearing:

The Characteristic Of Hammer

The material which made of hammer is very important, the higher hardness, the better toughness, the better wear-resistant, nowadays, our company is looking for more wear-resistant materials to replace the existing one.

The Characteristic Of Crushed Materials

Different size of materials has different wearing degree for hammer. And the shape of the materials has big influence on it. The sharp material is easy to pierce the surface of the material, while the round materials wear ability is relatively small. As for the material’s shape which processed by VSI crusher is irregular, so their wear for the equipment are very seriously.

The Influence Of The External Environmental

When the crushing working, as the speed of main shalt rotation is very fast, there is a very big impact force for the materials under the action of centrifugal force. When the materials impact the wearing parts continuously with high speed, so the wearing parts’ wear and tear is relatively fast, the speed of the impact velocity has an influence on wear and tear.

When the machine working, the materials will be collision with each other, and their impact on the key parts of the crusher is also irregular and random. So the impact of the collision perspective is also changing, as for the toughness materials, at the time of small particle materials for wear and tear , abrasion quantity will increase with the increase of the impact angle.
