Rod Mill
Rod Mill

Product Introduction:

A grinding equipment with steel rod as medium.

Production capacity: 0.62~250t/h

Product Improvement: Xinhai rod mills include overflow rod mill, end peripheral discharge rod mill and center peripheral discharge rod mill, which could meet different requirement.

Product Advantages:

  • The steel rod takes regular movement in mill.
  • It is convenient to install and maintain.
  • Rapidly discharging.
  • Even particle size of product, little over grinding.

Product Introduction:

The name of rob mill is from the medium in mill is steel rob. The rob mill is generally wet overflow type used in the first stage grinding, especially in artificial sand and stone, mineral processing plant and power sector of chemical plant.

Working principle:

The rod mill is driven by motor with speed reducer and peripheral large gear, or low speed synchronous motor with peripheral large gear. The grinding medium --- steel rod is put into the cylinder which is lifted, and then fall under the action of the centrifugal force and friction force. The materials entering into cylinder form the feeding inlet are grinded by movable grinding medium and discharged out by overflow and continuously feeding.

Product Structure:

Cylindrical energy saving grid ball mill consist of feeding part, discharging part, rotary part, transmission part (reducer, small gear, motors, electrical control) and other major parts. Hollow shaft is steel castings, and the liner is detachable. Rotary gear is processed by casting hobbing. The cylinder is lined wear-resistant liner plate with good resistance to wear. This machine works stably. The mill with coarse particle product is common used in the first stage grinding.

Grinding medium:

The grinding medium of rod mill is steel rod which is recognized that the length of rod is less than 7m because the large length is easy to twine. The diameter of rod is 75~150mm Grinding rod should have enough stiffness and hardness to keep straight, and it should not be too crisp which causes the rod broke into pieces without enough wear. If the rod is too soft, it is easy to bend and twine which makes trouble to clean machine (1)Rod mill is usually selected in order to prevent over grinding in gravity or magnetic separation plant of tungsten tin and other rare metals mine (2)In two stages grinding, the capacity of rod mill used in the first stage grinding is larger than ball mill’s (3)In some cases, rod mill can replace short head cone crusher
