Description

Technical Field

[0001] The invention relates to the field of rod mill sand making machines, in particular to a wet rod mill sand making machine. Background Art

[0002] The wet rod mill crushes the ore by the pressure and grinding force of the rods. When the rods hit the ore, the coarse particles are first crushed, and then the smaller particles are crushed; there is a line contact between the rods. When the rods rotate and rise along the cylinder wall, the coarse particles are sandwiched between them, similar to the bar screen, allowing fine particles to pass through the gaps between the rods, which is also conducive to crushing the coarse particles and concentrating the coarse particles where the grinding medium hits. Therefore, the rod mill has a selective grinding effect, and the product particle size is more uniform with less over-crushing. Among them, the double-feed rod mill sand making machine is widely used due to its high efficiency.

[0003] The existing wet rod mill sand making machine has the problem of difficulty in feeding the rod, because the steel rod is long and heavy, and it is normal for a single rod to weigh several hundred kilograms. Usually, it is necessary to use a lifting device and a rod feeding platform to achieve the feeding of the rod, but the axial footprint of the rod mill itself is very large, and the rod feeding platform that is not shorter than the steel rod further increases the floor space of the equipment. In addition, the biggest problem of the existing wet rod mill sand making machine is that as the work continues, the steel rod wears and becomes thinner. If it is not replaced in time, problems such as disordered rods, winding rods, and broken rods may occur, which may affect the grinding quality and grinding efficiency at the least, and damage the equipment at the worst, and even break the rods and fly out to injure people. At present, there is no good way to deal with the series of consequences caused by the wear of the steel rod. The steel rod can only be replaced regularly based on experience. If the machine is stopped too early, the steel rod can still be used. If it is taken out directly, it will waste materials and the steel rod cannot be used to the maximum extent. If the machine is stopped too late, the above-mentioned series of hazards may occur, which not only increases the maintenance workload, but also easily causes various other losses and casualties. There is a lack of means to timely discover the wear and thinning of the steel rod.

[0004] A Chinese patent with authorization announcement number CN216678466U discloses a rod mill. Through the setting of a connecting component, when it is necessary to feed a steel rod into the interior of the rod mill body, the height of the placement rack is adjusted by using the connecting component. When placing the steel rod, there is no need to lift the steel rod upward by manpower, thereby facilitating the steel rod to enter the rod mill body, reducing the labor intensity of manual labor and improving the processing efficiency.

[0005] However, the above-mentioned disclosed solutions have the following shortcomings: due to usage requirements, the length of the placement rack cannot be shorter than the length of the steel rod, which further increases the axial size of the rod mill, requires a large floor space, and cannot monitor the degree of wear of the internal steel rods in real time.
