Why ceramic plate with hole better than ceramic?

The hole plate has a number of qualities, including ease of fabrication, wear resistance, impact resistance, corrosion resistance, and high temperature resistance. It is the perfect material for conveying equipment used in the electric power, metallurgy, coal, petroleum, cement, chemical industry, machinery, and other industries to resist surface wear (such as ash, coal powder, fine ore powder, tailings, cement, etc.). When high temperature corrosion, high temperature wear, or high temperature melting occurs, it is extremely safe and dependable to use. In comparison to cast stone, wear-resistant alloy cast steel, steel plastic, steel rubber, and other materials, it has a ten to twenty times longer life.
