For a system of coal enterprise, the charcoal machine takes up a large investment in the budget cost, so the enterprise to control the cost before put into production, how in the effective time value for the enterprise to create more profit, for making charcoal factory, the use of charcoal machine lifespan is direct cost control range.
Charcoal machine is composed of several different devices, and each machine is composed of independent components, each component has become its own elements, decided the service life of the charcoal machine just made up of these elements. In these elements, shaft head is a common phenomenon, the wear of charcoal machine after a period of time after work, shaft head will appear different degree of wear and tear, these phenomena, also is cannot avoid.If single shaft head wear, wear if there is change, so frequent replacement will also be in imperceptible in increased cost, for this kind of phenomenon can be based on shaft head repair work to prolong the service life of the shaft head, can refer to charcoal machine in the shaft head repair welding technology for operation, the outer circle surface of uniform for carbon knot J422 electrode surfacing, more than the measured by standard cylindrical size 1 ~ 2 mm, left margin good polishing correction, preliminary grinding the revised insert charcoal machine spindle head dry lime or plant ash, cooled to 50 ℃ below complete grinding, grinding to with circular beating is not greater than 2 mm, and the circumferential surface have no obvious wet methods.
Charcoal machine parts in the repair work is completed, to handle with care to avoid collision, the repair work can complete the reuse of components, could also benefit from greater extent reduce costs for the enterprise, can make the enterprise will be more money into the production.
