Embodiment 1

[0027] (1) Preliminary cleaning: Add 15g of quartz sand, 40ml of water and balls into the ball mill for 10min at a speed of 330r / min, then replace the cleaning agent with 8g of corundum sand and 40ml of water for 10min at a speed of 330r / min , this cycle until the surface of the grinding ball is cleaned, take out the grinding ball after the ball milling is completed;

[0028] (2) Cleaning of the ball mill tank: use corundum sandpaper to wet-polish the inner wall and tank cover of the ball mill tank until the surface is bright;

[0029] (3) Post-processing and storage: Rinse the milling jars and balls treated in steps (1) and (2) with deionized water and alcohol, and then dry them for storage or soak them in absolute alcohol for storage.

Embodiment 2

[0031] (1) Preliminary cleaning: Add 15g of quartz sand, 40ml of water and balls into the ball mill for 50min at a speed of 220r / min, then replace the cleaning agent with 8g of corundum sand and 40ml of water for 50min at a speed of 220r / min , this cycle until the surface of the grinding ball is cleaned, take out the grinding ball after the ball milling is completed;

[0032] (2) Cleaning of the ball mill tank: use emery paper to wet-polish the inner wall of the ball mill tank and the tank cover until the surface is bright;

[0033] (3) Post-processing and storage: Rinse the milling jars and balls treated in steps (1) and (2) with deionized water and alcohol, and then dry them for storage or soak them in absolute alcohol for storage.

Embodiment 3

[0035] (1) Preliminary cleaning: Add 15g of quartz sand, 40ml of water and balls into the ball mill for 120min at a speed of 110r / min, then replace the cleaning agent with 8g of corundum and 40ml of water for 120min at a speed of 110r / min, Use this cycle until the surface of the grinding ball is cleaned, and take out the grinding ball after the ball milling is completed;

[0036] (2) Cleaning of the ball milling tank: use silicon carbide sandpaper to wet-polish the inner wall and tank cover of the ball milling tank until the surface is bright;

[0037] (3) Post-processing and storage: Rinse the milling jars and balls treated in steps (1) and (2) with deionized water and alcohol, and then dry them for storage or soak them in absolute alcohol for storage.

Abstract

The invention discloses a cleaning method of a tungsten carbide ball milling tank. The method comprises the following steps that primary cleaning is conducted on the tungsten carbide ball milling tankin a multi-ball milling mode by adopting a gravel and water mixture to effectively remove ball abrasives in the tungsten carbide tank and on a tungsten carbide grinding ball; then, a tank wall and atank cover are subjected to wet grinding by using sandpaper to be bright and then cleaning is conducted; finally, deionized water and alcohol are used for washing the ball milling tank and the grinding ball, drying or soaking in anhydrous alcohol for storing is conducted, so that the phenomenon that tungsten carbide is damaged, and therefore, the performance is influenced is guaranteed to be avoided; and Fe2O3 and Lu2O3 are taken as raw materials, and in LuFeO3 prepared through sintering after dry ball-milling through the cleaned tungsten carbide tank by using the method, no other impure phases generated due to the influence of the ball milling tank are found. The cleaning method of the tungsten carbide ball milling tank and the grinding ball can effectively remove chemicals attached to the inner wall of the ball milling tank and the grinding ball, and in addition, the phenomenon that the surface of a tank body and the surface of the grinding ball are acidified or oxidized, so that adverse effects are brought to the next ball milling is avoided.

Description

technical field [0001] The invention relates to the technical field of material chemical equipment, in particular to a cleaning method for a tungsten carbide ball mill jar. Background technique [0002] At present, in the process of manufacturing functional materials and targets, especially the preparation of ternary and above materials, it is necessary to mix the raw materials evenly. Generally, chemical precipitation method, sol-gel method and wet ball milling method can be used, but because the chemical precipitation method needs cumbersome steps such as dissolution, precipitation and cleaning, the sol-gel method needs cumbersome steps such as dissolution, glue mixing, gelling, and roasting. Wet ball milling often requires repeated ball milling and sintering during the sintering process, so the mixed raw materials tend to be mixed by high-energy dry ball milling. During the ball milling process, the raw materials are pulverized and mixed evenly by using the collision, fr...
