Abstract

The invention provides a continuous ball mill and a control method, and relates to the technical field of ball mills. The continuous ball mill comprises a ball milling mechanism, a driving mechanism,a feeding mechanism, a discharging mechanism and a controlling mechanism. The ball milling mechanism comprises a barrel body which is rotatable and is internally provided with a containing cavity, anda cavity partition plate used for partitioning the containing cavity into at least to grinding cavities; and the cavity partition plate is provided with a blocking zone and a communicating zone. Rawmaterials are ground to the size meeting the technical requirements after being ground by the multiple grinding cavities. According to the ball mill of the invention, the feeding mechanism of the ballmill uninterruptedly supplies the materials, the barrel body is in a continuous rotation grinding state, and thus, it can be ensured that the viscosity of ceramic slurry is not too high. In addition,the control method of the continuous ball mill of the invention, soft starting and precise stopping are achieved through a starter, and meanwhile, the influence of the continuous ball mill on networkvoltage is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of ball mills, in particular to a continuous ball mill and a control method. Background technique [0002] Ball mill is a common equipment in ceramic tile industry. [0003] At present, many ceramic wall and floor tile industries use intermittent ball mills, because ceramic mud is thixotropic in most cases, and the viscosity of thixotropic fluids is not only related to composition, temperature and velocity gradients, but also related to standing time. Specifically, the longer the ceramic slurry is left to stand, the greater its viscosity. Therefore, there are many unfavorable factors in the process of producing ceramic wall and floor tiles by using a batch ball mill. In addition, the ball mill is a kind of heavy-duty equipment, and its start-up will impact the power grid. In view of this, the inventor proposes the present application after studying the prior art. Contents of the invention [0004] The ...
