A: The whole body parts of the sand roller machine should be fully processed, the material of the roll skin hard but also fully processed (processing difficulty) the whole machine is equipped with a full hydraulic system, hard gear reducer (I plant using Jiangsu Guomao, Tyrone two products, the current domestic first-line brand, the price is higher than ordinary reducer nearly three times!) The weight of the machine is more than double the weight of other crushing with the same output, so the price is naturally high!
