Technical Field
The invention belongs to the technical field of powder metallurgy devices, and relates to a flow-rate-controllable continuous mixing device.
Background
The rapid development of powder metallurgy technology has led to an increasing demand for high-quality spherical metal powder and an increasing demand for powder quality. It is often necessary to mix powders of different particle size ranges together during the production process, with good control of the mixing time and the degree of homogeneity: too long mixing time can reduce production efficiency, prolong lead time, and the use can be influenced by the not enough degree of misce bene, causes final finished product spare to can't satisfy the requirement.
At present, a commonly used mixer is of a roller rotating type, namely rollers in various shapes slowly rotate under the drive of a motor, so that the mixing effect is achieved. The mixing mode is that a plurality of powders to be mixed are added into a roller together and are taken out after being mixed for a certain time. Such a method is not only inefficient in production, but also often requires the powder to be added in batches when a large amount of powder needs to be mixed, thus risking particle size differences between batches.
