Barley/Damai Traditional Chinese Medicine Coffee Bean Grinder Ultra-Fine Grinder Grains Corn Grinder Grinder

Just received the first day to dry the chili powder, the switch turned for 2 seconds and stopped, the machine is very big burning smell, the sound is very loud and terrifying, and the machine will run when it is running, you must hold the lid on the top of this to not run, there is a spark there on the switch, take a video to show the customer service, the customer service said to replace the carbon brush, but I don't understand why this new machine has just arrived to replace the carbon brush, and I don't understand what the carbon brush is, if it is a consumable, the customer service should prompt me to buy more spares, I am sending this overseas, It took a month to get it, it was difficult to do after-sales, and now I dare not use it, and I noted the British standard, and the national standard was issued as a result, hey, I don't know what to do
