Rod mill

Description

Rod mill is named because the abrasive body loaded in the cylinder is steel rod, rod mill is generally wet overflow type, can be used as a first-level open circuit grinding, widely used in artificial stone sand, concentrator, chemical plant power department of first-level grinding, global heavy industry production of the equipment reliable, rod mill price is reasonable. 

The rod mill has two forms of dry and wet to choose from, in addition to these two there is another is the overflow type rod mill, the user can choose according to their actual situation. So that our equipment can better handle our materials.

Performance Advantages

• 01: Save power Compared with the older equipment, the power saving is more than 40%. The particle size of the product is more uniform, and the coarse particles and slime are less. Compared with the particle size characteristics of the products of the rod mill and the ball mill, the product size characteristics of the open-circuit rod mill are almost the same as that of the closed-circuit ball mill.
• 03: Discharge particle size is more uniform, higher output The use of advanced controllable inlet and outlet rod mill technology, combined with the actual user's grinding materials with appropriate grinding body, a change of the traditional ball mill surface contact to line contact, so that Huali brand sand making machine discharge particle size is more uniform, higher yield, suitable for different hardness (Mohs hardness 5.5~12) of the ore.
• 03: the fineness of the discharge is adjustable The particle size of the discharge can be changed through simple adjustment, the built-in fineness control device, the discharge can be added screening device, two checks to ensure that neither over-grinding nor unqualified products will be mixed into the finished product. The particle size characteristics of rod grinding products are related to the situation of rod grinding ore. When the rod strikes the ore, it first hits the coarse particles before grinding the smaller ones, thereby reducing the risk of over-crushing. When the rod is rotated along the lining plate, the coarse particles are caught between them, like the bar sieve, so that the fine particles pass through the cracks of the rod, which also helps to crush the coarse particles and concentrate the coarse particles where the grinding medium hits. Therefore, the product of rod grinding is more uniform, and the overgrinding is lighter.

Working Principle

When working, the motor is driven by the reducer and the surrounding big gear or the low-speed synchronous motor is directly driven by the surrounding big gear to drive the cylinder to turn. The cylinder body is equipped with the appropriate grinding medium - steel rod. The grinding medium is raised to a certain height under the action of centrifugal force and friction force, and falls in the state of throwing or sliding. The ground material is continuously entered into the cylinder by the feed port, crushed by the moving grinding medium, and the product is discharged out of the machine by the overflow and the continuous feed force to carry out the next process operation.

Question&Answer

Q:What is the cause of the slurry leakage at the connection between the end cap and the cylinder? How to solve it?

A:Possible causes: 1. The connection bolt is loose and the pin is too long. 2. The liner screws are loose, the gasket is worn or the screws are broken.

Solution: Tighten and replace the bolts. Tighten the positioning pins and replace the gasket.
