A mining ball mill and its electric control system

Abstract

The invention specifically relates to a mining ball mill and an electric control system thereof, belonging to the field of mining machinery. The mining ball mill comprises a barrel, a mounting plate,a first motor, grinding balls, an ejection unit and a collecting box. Through arrangement of the first motor, the grinding balls and the ejection unit and the interaction among elastic bands, gears, racks, ejection plates, mounting blocks and limiting blocks, the elastic bands rotate to realize contraction and extension so as to allow the ejection plates to eject the grinding balls, so the grinding balls are improved in impact, friction and shearing effects on gold ore particles and fully grind the gold ore particles, which enables the grinding efficiency and effect of the gold ore particles to be improved; moreover, a power source generated during grinding of the gold ore particles is utilized, so an additional power source is not needed, and thus, the utilization rate of resources is improved and the manufacturing cost for the mining ball mill is reduced.

Description

technical field [0001] The invention belongs to the field of mining machinery, in particular to a mining ball mill and its electric control system. Background technique [0002] The ball mill is mainly used for grinding materials. The existing ball mill mainly grinds the material into powder through a horizontal cylinder and a grinding body arranged in the cylinder. The grinding body rolls in the cylinder and collides with the material. In the existing edge-driven ball mill, the small gear on the transmission gear shaft on the driving device meshes with the large gear fixed on the tail to drive the mill to rotate. Therefore, the grinding effect of the existing edge-driven ball mill is poor, and the required completion time for slow grinding is long, and its efficiency is not high. [0003] There is also a patent in the prior art about a technical solution of a mining ball mill and its electric control system. For example, a Chinese patent with application number 20171066954...

Problems solved by technology

[0004] A ball mill in this technical solution can solve the problem of excessive temperature in material grinding

However, in this technical solution, the motor is completely relied on to drive the grinding machine to rotate, and the impact of the grinding ball on the material is small, and the grinding ball cannot fully grind the material, thereby affecting the grinding efficiency and effect of the material; The power source is utilized, but an additional power source is added, thereby affecting the utilization of resources and increasing the manufacturing cost of the grinding machine; making this technical solution limited
