Description

Lime raw material ball mill Technical Field The utility model relates to the technical field of lime production equipment, in particular to a lime raw material ball mill. Background In the lime production industry, a lime raw material ball mill is used as key equipment, and plays a decisive role in the efficiency and quality of lime production. Conventional lime feed ball mills have exposed a number of problems during actual operation. Firstly, in the feeding step, most ball mills are only provided with a simple conveying device, and the lime raw materials cannot be pretreated. Lime raw materials are generally different in size, and directly enter a ball mill roller for grinding, so that excessive abrasion of grinding media in the ball mill can be caused, grinding efficiency can be reduced, and energy consumption is increased. Secondly, the conveying mechanism and the crushing assembly independently operate and are respectively provided with a power source, so that the equipment cost is increased, the whole equipment structure is more complex, more space is occupied, and meanwhile, the equipment maintenance difficulty and the equipment maintenance cost are also improved. Disclosure of Invention In order to solve the defects in the prior art, the utility model aims to provide the lime raw material ball mill, which is characterized in that a crushing assembly is arranged at a feeding end to primarily crush lime raw materials, so that the particle size of the raw materials entering a roller is reduced, and grinding media in the roller can grind the raw materials more effectively, thereby improving the grinding efficiency.
