Wet mill

Abstract

The invention discloses a wet mill. The wet mill comprises a ball milling cylinder, the upper portion of the ball milling cylinder is provided with a ball outlet and a chain wheel respectively, the lower portion of the ball milling cylinder is provided with an inclined hopper and a slag discharging port, the lower end of the inner portion of the ball milling cylinder is further provided with a ball barrier, one side of the ball milling cylinder is connected with a feeding pipe, the end, away from the ball milling cylinder, of the feeding pipe is a feeding port, the two sides of the feeding pipe are connected with a circulating pipe and a solvent inlet pipe respectively, one side of the solvent inlet pipe is connected with an exhaust pipe, the other end, away from the feeding pipe, of the circulating pipe is connected with the slag discharging port formed in the lower portion of the ball milling cylinder, a filtering device, a slurry pump and a three-way valve are arranged in a pipe body, close to the slag discharging port, of the circulating pipe respectively. The wet mill has the beneficial effects that automatic feeding, wet milling and exhausting are achieved, slurry temperaturecontrol and in-cylinder pressure monitoring are added, the whole equipment operation process is controlled by a computer, full-automatic operation of the wet mill is achieved, the labor cost of an enterprise is reduced, the production efficiency of the enterprise is improved, and meanwhile the potential safety hazard that a cylinder is prone to explosion is avoided.

Description

technical field [0001] The invention relates to the technical field of cemented carbide wet grinding, in particular to a wet grinding machine. Background technique [0002] Wet grinding is to put balls, powder, and solvent into the grinding cylinder according to a certain ratio for ball grinding. The wet grinding produced by cemented carbide has some characteristics: the powder is very hard, the solvent has a low boiling point, and requires low temperature and air isolation to prevent oxygenation. , high uniformity requirements, currently there are two main methods used: one is the tilting wet mill of rolling ball mill, and the other is vertical stirring ball mill; [0003] At present, the domestic cemented carbide industry mostly uses tilting wet grinding machines (more than 90%). Due to various reasons, the two kinds of ball mills are basically not automated for the time being. When they are used, there are many manual components and high labor intensity. Taking the tilt...

Problems solved by technology

Due to various reasons, the two ball mills are basically not automated for the time being. When they are used, there are many manual components and high labor intensity.

Taking the tilting wet mill as an example, when feeding materials, the gland needs to be opened manually, the materials are fed manually, and the solvent is added. It becomes a gaseous state to generate pressure, and it is necessary to manually "deflate" regularly to eliminate the risk of cylinder explosion. After ball milling, the gland is manually replaced with a discharge hopper. It is necessary to tilt the cylinder several times, add solvent and discharge the slurry to achieve For the purpose of cleaning, this operation method is time-consuming and laborious, and there are many steps in the operation, which seriously reduces the production efficiency of the enterprise, and the labor cost is relatively high.
