3.The processing capacity of rod mill is bigger than ball mill for the coarse crushing on the same specifications, and vice versa.
How is it working? this ball mill machine is a skeleton pattern ball mill with horizontal cylindrical turning gear, drive by outer gear and two hoppers.The material goes to the first hopper after the spiraling by the quill shaft from the feeding and dryer machine.The hopper has ladder sheathing or corrugated sheathing with steel balls inside, which will fall under the effect of centrifugal force by barrel turning to ram hard and grind material.After the kibbling in the first hopper, by monolayer partition panel, the material will enter the second hopper, which has plane scale board with steel ball inside to grind material.The powder material will be discharged from the grid plate to finish the grinding.
Ball mill machine tools are up for sale at various outlets and online stores.But before buying you must know them well.These gadgets are primarily used for single stage fine grinding and regrinding, and as a second stage for two stage grinding circuits.As per the need of the consumer, ball mills can have either wet or dry designs.Ball mills are designed with standard sizes of the final product.

Ball mill loading (wet milling)when charging a ball mill, ceramic lined mill, pebble mill, jar mill or laboratory jar use on a jar rolling mill it is important to have the correct amount of media and correct amount of product.Charging a wet mill the general operation of a grinding mill is to have the product impacted between the balls as they tumble.Unlike dry milling, wet milling is more straight forward and more forgiving in terms of charging the product.As with dry milling there should be at least 25% liquid to fill the void space plus a bit more to insure the balls are striking product and not each other.Of course the surface tension of the liquid used will greatly affect the ability of the solids to be both suspended in the liquid and to form a film on the grinding media.Product viscosity in a factor in wet milling.The more viscous the liquid the slower the media velocity (stokes law) and, therefore, the less energy imparted into the product.Again following stokes law, the smaller the media, and the greater it surfaces area to and the slower its velocity falling through the fluid.Common starting points for the viscosity limits: <1000 cps for alumina media <2000 cps for steel media the starting point for ball mill media and liquid charging is generally as follows:50% media chargeassuming 26% void space between spherical balls (non-spherical, irregularly shaped and mixed-size media will increase or decrease the free space)50% x 26% = 13% free spaceadd to this another 45% to 50% above the ball charge for total of 58% to 63% product loading.This level of liquid loading should leave some air space above the liquid to allow for expansion of the liquid as it heats up during the milling process.So as a rule of thumb we use a maximum of 60% liquid loading.
In the grinding process, the grinding media make a line contact with ores, so it has a certain effect on selectivity and grinding.The particle size of dry rod mill product is relatively uniform.When used for coarse grinding, the processing capacity of rod mill is better than that of other ball mill with same specification, and the reverse is also true.
Largest size of clinker is 60mm , 100% damper openning at mill fan , no hole for fresh air at mill inlet also no hole for water injection.Our ball mill is operated manually not automatic.
Our ball mills can satisfy different requirement, and have good features such as low consumption, high capacity per hour, no pollution to the environment around, easy to be repaired.We have the good service to our customers, if they can't install the machines, we can send our technician come to your location, and install for you.We make every endeavor to satisfy our customers.
The results show that under the same conditions of grinding fineness, the fluorite concentrate by rod mill obtains a lower si o2 content.Compared with ball milling, the particle size of rod grinding is more uniform, rod mill control the grinding fineness better.
The iron ore ball mill adopts a closed system to achieve less dust and low noise, which greatly reduces the harm to workers and the cost of enterprise environmental protection.
Ball mill: when the particle size of the product is less than 0.5mm, the grinding effect of the ball mill is greater than that of a rod mill of the same specification.
The noises produced by the energy-saving ball are generated by the impacting and grinding between steel ball, materials and scare board.The noise belongs to the mechanical noise and radiate outside along with the surface of the tank.The noise can be different when the size and quantity of the crushing material is different, even the same type energy-saving ball mill in the same sand making line.
