Industry Information

The scale of advantageous enterprises continues to expand

At present, China's grinding industry concentration is low, more manufacturers; Moreover, the technical difference of various manufacturers is great, and the homogenization and disorderly competition are serious, which has compressed the profit level of the whole industry and affected the competitiveness of China's abrasive media products in the international market. With the guidance of national industrial policy and the tightening of environmental protection policy, large production enterprises with capital and technological advantages will gradually gain a larger market share; We will gradually cancel investment in environmental protection.

Environmental protection and safety requirements are becoming more and more stringent

In recent years, with the increasingly strict environmental protection and safety policies, grinding ball manufacturing industry and its downstream industry environmental protection pressure is increasing.Production capacity.Therefore, it is imperative to upgrade the products and technology of grinding ball manufacturers.

The product structure is unreasonable, and technological innovation needs to be strengthened

In recent years, China's grinding ball industry in product performance, quality, stability, technology and other aspects have significantly improved, grinding ball production and sales are in the forefront of the world; But the product structure is still unreasonable, the products are mostly conventional varieties, low added value. Homogenization phenomenon is more serious, some varieties overcapacity.
