Description
Technical Field
The invention relates to the field of mills, in particular to a large modular high-energy mill.
Background
The traditional ball mill is a grinding device which mainly adopts impact grinding and assists in rolling and grinding, a rotary cylinder of the ball mill brings materials and media (such as steel balls and steel forgings) to a certain height and then the materials and the media are discharged downwards, impact grinding between the media and the materials is completed in the discharging process, and the impact process is accompanied with the speed difference between the grinding media, so that the rolling speed difference and the grinding speed difference between the grinding media are generated, and the materials are ground. The speed that material and medium paste the barrel rotation is the critical speed of traditional ball mill, and when mill rotatory barrel rotational speed was higher than critical speed, the material can paste the barrel rotation, no longer produces and lets out, along with to the bigger processing energy demand of single equipment when, mill barrel diameter just need increase, and critical speed can be more and more low. The filling rate of the medium is lower and lower, so that the speed difference between rolling and grinding is smaller and smaller, the traditional ball mill is not suitable for the industrial application field of fine grinding or ultrafine grinding at all, the large-scale industrial application of fine grinding and ultrafine grinding can be realized only by increasing the speed difference between rolling and grinding or completely removing impact grinding, and the traditional ball mill cannot be applied to the mineral grinding field of fine grinding or ultrafine grinding at all due to the limitations of impact grinding, critical rotating speed and medium filling rate. In addition, the impact between the media causes the plastic deformation of the material, the plastic deformation is finally expressed as the abrasion of the media and the heating of the media, and the plastic deformation cannot be converted into the grinding capacity of the mineral, so that the effective work of the mill is greatly reduced.
The known fine grinding or ultrafine grinding equipment is generally applied to a vertical spiral stirring mill or a horizontal spiral stirring mill of wet grinding ore, and the known fine grinding or ultrafine grinding equipment is generally only suitable for wet grinding ore and cannot realize dry grinding ore, so that the grinding equipment which is universal for dry grinding and wet grinding becomes an industrial difficulty to be solved urgently. In addition, in order to realize fine grinding and ultrafine grinding, the known fine grinding or ultrafine grinding equipment increases the flow velocity of the medium by stirring the grinding ball medium, and adopts the way of increasing the energy input density to realize grinding, although the grinding way can realize fine grinding or ultrafine grinding, after the flow velocity of the medium is increased to a certain degree, after the linear velocity of the medium is increased to a certain degree, the medium is subjected to plastic deformation due to mutual strong extrusion between the media, the plastic deformation can be finally converted into heat, the energy consumption is overlarge, the efficiency of converting the input energy into grinding energy is too low, and therefore, the mineral processing cost in the field of fine grinding or ultrafine grinding wet grinding is high.
In the prior art, there is an apparatus for dry grinding and fine grinding: the single-cylinder vibration mill or the multi-cylinder vibration mill mostly adopts a center driving mode, a cylinder body does circular motion around the center, the motion mode has the phenomenon that steel ball media collide violently, so that the energy consumption is overlarge, meanwhile, the large-scale industrial production cannot be realized due to the structural limitation and the volume limitation of the cylinder body, the small-batch intermittent ultrafine powder processing can be realized only by the vibration mill, and the requirements of large-scale, high ball loading rate, low energy consumption, dry milling and wet milling general ultrafine grinding large-scale production required by the industrial production cannot be well met.

The invention is suitable for large-scale modularized high-energy mills, each cylinder body is provided with an independent exciting device installation base and a balance weight, and each cylinder body can be connected with other cylinder bodies, so that the length of the mill is prolonged. This provides a unique solution for the realization of high-energy mills for continuous grinding of ores. According to the invention, the vibratory mill is horizontally arranged, so that dry-method and wet-method ore milling can be realized, and the mill cylinder is supported by the spring base on the cylinder and the spring, so that the modularization and large-scale of the mill are well completed, and the processing, manufacturing and transportation are convenient.
The invention can make the two sides of the mill cylinder generate amplitude difference by one side excitation and the other side only by the alternative energy storage and release capacity of the spring, realizes the rolling of the steel ball medium by the amplitude difference, when the speed of the excitation side is fast enough, the rolling speed difference of the steel ball at the excitation side can exceed the critical speed of the traditional ball mill, the invention breaks through the limit of the critical speed of the traditional ball mill, greatly enlarges the rolling and grinding speed difference between the steel ball medium, because the amplitude is less than 20mm, the steel ball is difficult to be brought to a certain height, and the impact grinding between the steel ball medium is also completely avoided, thereby avoiding the plastic deformation of the steel ball medium, and converting more input energy into the grinding energy caused by the rolling and grinding speed difference.
The revolution speed (medium linear velocity) of the steel ball medium in the cylinder module of the invention is obviously lower than that of mills with stirring devices, such as a spiral stirring mill or a disc mill, and the like, and the energy density of the high-energy mill is lower than that of the mill with the stirring devices, so that the volume of the cylinder body of the mill needs to be increased, thereby realizing high ball loading rate and high energy conversion rate of the mill. The invention can well realize the connection between the cylinder bodies, thereby increasing the volume of the cylinder body of the mill, and further realizing the excellent characteristics of high medium filling rate, high energy utilization rate and low energy consumption.
In conclusion, the cylinder structure designed by the invention has the characteristics of large size, high ball loading rate and low energy consumption, is an ultra-fine grinding device which is universal for dry grinding and wet grinding, is different from any known grinding equipment for fine grinding and ultra-fine grinding, and the appearance of the device is bound to subvert the processes of fine grinding and ultra-fine grinding for mineral processing and subvert the traditional processing processes in the fields of building materials and powder processing.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that it will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the principle of the present invention, and such modifications and improvements should also be considered within the scope of the present invention.
