Grinding roller is one of the most commonly used Raymond Mill powder machine accessories, just like car tires, has a service life, belongs to consumables, normal use will wear.
If powder manufacturers buy Raymond Mill powder machine accessories to buy the heat treatment is not qualified grinding roller, there will be a lot of problems: such as grinding roller wear too fast, grinding roller cracking, grinding roller surface wear uneven, which will cause economic losses to Raymond mill powder machine users.
The following figure is the wear condition of the unqualified heat treatment roller:
The following figure shows the wear condition of the qualified roller:
Mechanical people know that as long as the casting, should be heat treatment stress annealing (also known as low temperature annealing).
It is used to eliminate the casting stress and reduce the tendency of deformation and cracking.
The main reason why the wear of Raymond mill powder machine roller is too fast and not wear-resistant, the grinding roller is cracked, and the surface of the grinding roller is worn unevenly is that the heat treatment of the grinding roller is not handled well in the process of casting.
If the annealing temperature is too low or the holding time is insufficient, or the cooling speed is too fast;
In solid solution treatment, the temperature is too low or the holding time is not enough or the quenching transfer time is too long or the quenching water temperature is too high;
Under incomplete artificial aging and complete artificial aging, the temperature is too high or too low, and the time is too long or too short.
GuiLin HangDa Mining Machinery Co.,LTD. Is a leading technology manufacturer in the mining machinery industry in guilin, with its own foundry workshop, heat treatment workshop and gold processing workshop, the casting process is advanced, the use of expensive lost die technology production roller embryo has beautiful appearance, no sand and other advantages.
Roller casting is of high quality.
The grinding roller in the spare parts of the Raymond mill powder machine of GuiLin HangDa Mining Machinery Co.,LTD. is the alloy raw material, and an appropriate amount of manganese, chromium and other metal elements are added into the grinding ring.
Due to the precise control of the proportion of manganese, chromium and other metal elements, coupled with advanced casting technology, our company's alloy mill than the ordinary grinding roll more wear resistance, not easy to crack.
The company in addition to the supply of the company's Raymond machine accessories, but also can customize the Guilin Raymond mill powder machine, Henan Raymond mill powder machine, Shanghai Raymond mill powder machine and other Raymond mill powder machine manufacturers Raymond machine vulnerable parts.
