In the sand and gravel production line can be uniformly continuously feeding the crusher crusher by avoiding clogging of the discharge port. Is the use of a vibrator in the centrifugal force generated by the rotation of the eccentric vertical milling machine, the screening car, vibrators and other moving parts as mandatory continuous circular or approximately circular motion. Material in the car with the screen tilted screen surface for continuous throwing motion, and continuously fed by material uniformly within the discharge. Of course, Raymond mill, at the time of purchase, the most taboo blind pursuit of low prices. It is an indisputable fact, a sub-price goods, bought the mill to buy a clothes different from the milling machine, which is large production machinery, not luck, otherwise, it will only bring to their production problems. Good equipment, which at the time of selection, there are certain principles, therefore, the price may be appropriate to enhance long as it is within a reasonable range, you can consider buying.
