Burdening process in graphite electrode production
The burdening are the production process of calculating, weighing and focusing the aggregates, powders and binders of various sizes according to the requirements of the formula. The scientific suitability of the formula and the stability of the burdening operation are one of the most important factors affecting product quality indicators and performance.
The formula needs to determine 5 aspects:
①Choose the type of raw materials;
②Determine the ratio of different types of raw materials;
③Determine the particle size composition of solid raw materials;
④Determine the amount of binder;
⑤Determine the type and amount of additives.
