Abrasive environment means abrasive object, the contact between the wear-resistant materials and abrasive material, the relative motion state, the interaction between, the total capacity of the cavity and its temperature, humidity. Sand making equipment for the mining equipment industry, mineral processing equipment (ore dressing equipment) are more serious corrosion in the production process of products, especially in the sand making machine sand making equipment, sand washing machines, vibrating screen, rod mill frictional contact, jaw crusher, etc., in the production process and long-term stone or other materials, it is tolerance to be abrasive.
The wear mechanisms can be divided into abrasive wear, impact wear, sliding wear, contact fatigue wear, fretting wear, erosive wear, adhesive wear and abrasive wear, including abrasive wear accounted for more than 50% of all wear and tear caused by loss, most of the cement industry to abrasive wear as the main wear mode.So-called Abrasion - abrasive material wear and tear caused by surface wear and tear means: abrasive or hard asperities and surface material interaction. Such as wear and tear caused by the relative movement of the parts of the equipment and ore, sand, soil, clinker, coal and other friction.The abrasive wear abrasive wear surface of the stress and shock size is divided into a chisel, high-stress abrasion and low stress abrasion.
1) chisel cut abrasive wear characteristics of such wear is the impact of abrasive cut into the metal surface with a great impact on large particles of metal from the friction surface chisel cut deeper grooves in the worn surface and indentation. Such as ore crusher hammer and other parts of the surface of the wear and tear.
2) the high stress abrasive wear, the type of wear is characterized by high stress abrasive stress of more than the crushing strength of the abrasive. The abrasive particles were crushed polygon, abrasions metal left on the friction surface grooves and pits. Such as ore crushing damage to the surface of the machine palate.
3) low stress abrasion, the wear characteristics of low stress abrasive role of stress on the friction surface does not exceed its own crushing strength. Surface scratches and a tiny cutting traces. Drunk sand pump impeller wear. With its high quality products such as Rotary kiln, Hammer crusher, Henan Hongxing mining machinery Co.Ltd has ascended in the front rank of the world in the exporting of mining equipments.
