Slice mills are identical to the ball mills and ceramic lined mills in diameter and design the only difference is that they are as little as 12 in length.Since mill diameter dictates performance and mill length only affects capacity, slice mills are used to develop or test formulations with little concern for scal (more.).
During the crushing process, the fine aggregate can be pulverized again by using a ball mill.The secondary screeningcandivide the crushed aggregate into 5-20mmwith high-qualityof recycled aggregate, which can be used for c25-c30 concrete production.The third-stage screening can sortout the recycled fine aggregatewith high qualityin 0.15mm-5mm and fine powder below0.15 mm.
According to different ways of discharging, the ball mill gets different names: grate discharge ball mill and overflow discharge ball mill.
Structure of dry ball mill:the machine is composed by feeding part, discharging part, turning part and driving part (reducer, small driving gear, electric motor and electric control).The quill shaft adopts cast steel part and the liner is detachable.The turning gearwheel adopts casting hobbing process and the drum is equipped with wear-resistant liner, which has good wear-resistance.The machine is with stable and reliable working condition.Moreover, according to different materials and discharging methods, there are dry ball mills and wet ball mills for choice.
Moreover, the results obtained from dem usually should be validated with experiments.In this paper, simulation results of particle behaviour, mill torque, and power consumption obtained from dem simulation are compared with experimental results in detail to validate the correctness of the simulation results.Especially, the particle behaviour is validated both qualitatively and quantitatively.The dem results are shown to be highly consistent with the experimental results.The torque of liners and baffles are affected by lifter height, lifter number, and mill speed.Moreover, the changes in the torque and power consumption of a ball mill can be effectively explained using two important factors: lifter and particle area ratio.

As a professional manufacturer of ball mill equipment, fote heavy machinery has continuously improved its research and development of ball mills with 40 years of experience.
We are engaged in the manufacture and supply of a wide assortment of ball mills that are used for grinding the crushed materials.
This kind of ball mill advantages are: simple process, easy to operation and less investment in infrastructure.Impact crusher its disadvantages are: easy to over-grinding.Namely: the mill just output the material when all the materials are up to standard.The materials which are easy to grind will form a buffer layer and hinder other materials grinding.Sometimes it even has the phenomenon of fine powder ball which will reduce the efficiency, yield and increase the power consumption.Belt conveyor high-pressure closed-circuit system is just opposite with high-pressure micro powder mill system.The advantages: it can eliminate the over-grinding phenomenon, and reduce the temperature in the mill.Cement production line it has high grinding efficiency, high output, and the specifications of the cement mill production is generally increased by 10 ~ 20%, raw mill can be increased by 30 percent.Its disadvantages are: complex processes,raw material mill more equipment, high requirement of operation and management, large investment in infrastructure.
This coal ball mill is made up of feeding part, discharging part, gyre part, transmission part (transmission part includes reducer, small transmission gear, generator and electrical control) and so on.It enjoys features like good abrasive resistance, stable and reliable operation.Inner structure of the coal ball mill is made up of lining plate, grate plate, diaphragm, feeding and discharging devices.Different types of lining plates can be used to adjust the movement of materials.Our lining plates are provided by luoyang anti-abrasion academe and have a large share in the global market with their fine design.The lining plate is used to protect the tank body in order to avoid the impact and abrasion from materials.
