Our company is a private manufacturer which produces high quality wear-resistant materials including grinding media, wear-liners and crusher-hammers etc. We have more than 1000 ton products in our storage. Our major product –high chrome grinding balls' max chromium content has reached to 30%. We have experiences of export as to Russia, Egypt, South Africa, Bangladesh, Korea and Middle East etc of more than 20 countries in the world.
In addition to that, our company is also in connection with our famous domestic research institutions to provide structure design and parameter regulations of mill service to realize the goals and synthetic benefits of capacity increasing, power economizing, proportion of cement surface area optimizing, mineral powder fineness increasing, media consumption decreasing and liner plates’ service life prolonging etc.
In the casual sampling inspection in the National Authoritative Quality Test Center in our country, all parameters of our products reached the national standard, the chromium content which was related to products' quality and price have all reached the requirements we had promised to our customers. After special quenching and tempering heat treatment, our products’ hardness still far surpassed the national standard of 58 HRC which even reached marvelous 69 HRC (70 is the highest value in Rockwell hardness.) Our maximum and average hardness all exceeded the values of other companies in this industry with 18% plus of the national standard. The average hardness reached to 65.3 HRC, higher with 13% of the national standard. The hardness tolerance was controlled within 3 HRC. We extracted our 100 centimeter big casting balls to receive the International Current V- Style all Absorbing Impact Test then got a very good result of 1.3KV of impact tenacity.
We emphasize product quality and customer’s actual needs, and all our products sold had passed the national quality standards and fit very much to customer’s actual utilizing circumstances.
We see clients' profits as our main focus and pursuit, so we have always being struggling to research the best products which are able to resist the severe friction, chemical attacks, thermal shocks and mechanical stresses etc. we are confident and trying to face any challenge both in quality and in service requirement. For the vast customers around the world, there is no reason for us to slow down.
Due to our consistent efforts and insistence, we have designed many new products with specific superior properties which also formed our patent certificates, we have 12 of them. Also since establishing time to now our company has won many prizes in our industry both in city level and province level.
We have very advanced and comprehensive producing and quality testing equipments many of which were imported from abroad to standardize our craft. Our administration and production are also very advanced and effective.
Our company is located in a town so our cost is relatively much lower so our finished product’s price is relatively much lower too but still on condition of reaching the quality requirements already.
