Problems solved by technology

[0002] The ball mill cylinder and the driving motor of the current ball mill are matched and driven by a heavy-duty elastic pin coupling, which starts directly with a load, which has a large impact on the power grid and lasts for a long time. The starting current is 2.5 times the rated current of the motor. Larger, the starting power is 2.5 times the rated power, which reduces the service life of mechanical equipment

Abstract

The invention discloses a ball mill connecting shaft device, relating to the technical field of ball mills. The ball mill connecting shaft device comprises a ball mill, a transmission shaft, an air pressure clutch and a synchronous motor, wherein the transmission shaft is sequentially connected with the ball mill, the air pressure clutch and the synchronous motor. By using the ball mill connecting shaft device, the defect of difficulty in starting caused by on-load starting and large rotational inertia of heavy mechanical equipment is overcome, and the service life of the ball mill connecting shaft device is prolonged.

Description

technical field [0001] The invention belongs to the technical field of ball mills, in particular to a ball mill coupling device. Background technique [0002] The ball mill cylinder and the driving motor of the current ball mill are matched and driven by a heavy-duty elastic pin coupling, which starts directly with a load, which has a large impact on the power grid and lasts for a long time. The starting current is 2.5 times the rated current of the motor. Larger, the starting power is 2.5 times the rated power, which reduces the service life of mechanical equipment. Contents of the invention [0003] The invention aims at the deficiencies of the prior art, and provides a ball mill coupling device with small current load, easy start-up and high service life. [0004] In order to solve the above-mentioned technical problems, the present invention provides the following technical solutions: The utility model is a new ball mill coupling device, which includes a ball mill, a ...
