[0002] At present, the existing ore separation device in the mineral processing laboratory is generally composed of a small mixer connected to a mixing barrel. The mixing barrel is opened on the side and connected by a rubber hose. The ore discharge is controlled by a water stop clamp. The sample divider is not equipped with a filter, and the large particles of minerals in the slurry cannot be separated, which will cause the ore discharge hole to be blocked. Some medium-sized particles that can pass through the ore discharge hole will also block the flotation machine's inflation hole or jam the mixing wheel, causing trouble for subsequent flotation operations. Moreover, the mixing barrel is mostly a conventional flat-bottomed cylindrical barrel. After the ore is discharged, it needs to be Manual water is added to clean the mixing barrel. Since the mixing barrel has a flat bottom and the slurry is evenly dispersed, it is necessary to rely on external force to tilt the entire sampler so that the residual slurry flows to the side of the side opening position to discharge the slurry. The entire operation is laborious and it is difficult for people with less strength to complete the cleaning operation alone. In addition, the sampler is not equipped with a load-bearing platform, and a stool is needed to support the sample receiving vessel.
