Automatic cooling device for high-temperature grinding balls and grinding ball production device

Abstract

The invention discloses an automatic cooling device for high-temperature grinding balls. The automatic cooling device comprises a sliding chute and a spiral elevator, one end of the sliding chute is connected to an outlet of a grinding ball production line, the other end of the sliding chute extends downwards and extends into a soaking cooling pool via a water sprinkling cooling pool, water sprinkling devices for sprinkling water to the grinding balls are arranged above the water sprinkling cooling pool, cooling water is contained in the soaking cooling pool, the bottom of the spiral elevatoris immersed in the soaking cooling pool, and the bottom end of an elevating tank of the spiral elevator is connected to the bottom end of the sliding chute. According to the automatic cooling device,the high-temperature grinding balls roll downwards along the sliding chute under the action of gravity and firstly pass through the water sprinkling cooling pool to be preliminarily cooled with the sprinkled water, a large amount of generated water vapor is liquefied when encountering sprinkled water drops in the ascending process and falls into a pool, then the grinding balls roll into the soaking cooling pool to be secondarily cooled with the cooling water and then are lifted out of the soaking cooling pool by the spiral elevator, the whole cooling operation is completed automatically, the labor intensity is low, the safety is high, and the water loss is small. The invention further discloses a grinding ball production device comprising the automatic cooling device for the high-temperature grinding ball.

Description

technical field [0001] The invention relates to the technical field of beneficiation grinding ball production, in particular to an automatic cooling device for high-temperature grinding balls. In addition, the present invention also relates to a grinding ball production device comprising the above-mentioned high-temperature grinding ball automatic cooling device. Background technique [0002] In the field of mining, ore grinding is an important part of beneficiation operations, and grinding balls are ball stones that are widely used as grinding media. The grinding balls are driven to produce complex impact, grinding and shearing effects on the ore, and finally the ore is ground. [0003] At present, the high-temperature grinding balls (about 950°C) produced by most grinding ball production lines mainly have two cooling methods: one is manually transported to the autocratic house for stacking, and then sprinkled for cooling; the other is to immerse the high-temperature grind...

AI Technical Summary

Problems solved by technology

These two methods mainly have the following disadvantages: The first method is manual handling of high-temperature grinding balls, which is labor-intensive and the working environment is harsh. The sliding of the grinding balls during the stacking and unloading process is likely to cause personal accidents, and the cooling water is easily polluted and difficult to recycle. Big; Mode 2: A large amount of water vapor will be generated instantly when the high-temperature grinding ball is immersed in the pool, which is easy to cause personal accidents, and the water loss is large. In addition, the cooled grinding ball needs to be manually fished out, and the degree of automation is low.

[0004] Therefore, how to solve the problems of time-consuming and labor-intensive cooling of high-temperature grinding balls, large water loss, and easy personal injury is a technical problem that those skilled in the art need to solve at present.
