Working in the coal mine, the use life of the teeth pin is the longest

　　Generally speaking, the current working condition and situations also provide a very important role on the total use life of the China bucket tooth pin, in the other words, working in the different mine places, the use life of the China bucket tooth pin could has some big different at the end. For example, if the main working condition of the China bucket tooth pin is in coal mine, because compared with iron mine, the hardness of the coal is smaller, it only range from three to five, besides, the total weight for per coal mine is only about two hundreds kilograms, so these factors has causes the China bucket tooth pin would has a smaller abrasion damage during the normal digging time.
