In the modern industrial sector, certain raw materials must be thoroughly mixed by a blender before they can be used. To ensure the integrity of the mixing equipment in the hands of users, manufacturers must conduct an outgoing inspection at the end of production before the equipment can be sold. What specific checks are carried out? Let's take a brief look at the relevant knowledge points below.

Noise, the significant noise during material mixing, measured by a sound level meter at a distance of 1 meter in front of the machine's discharge position, at a height of 1.5 meters.

2. Thermometer devices record the readings from the cold machine's thermometer during the heat engine and production detection processes, comparing them to the temperature directly measured in the discharged mixed material with a thermometer. Only after passing the corresponding inspection can the safety of the joint compound mixer be ensured, and it can be sold normally.

3. Quality: Measure the quality of the feedstock by weight, record the cycle time for each production process under conditions of well-mixed procedures. The output is calculated as the material mass mixed within a unit of time, and the average of three measurements is taken.

4. Assembly accuracy testing includes the radial runout at the outer diameter of the main shaft and the dry powder mixer impeller's blade mating point. The test is conducted at the upper position of the main shaft, where the shaft is rotated continuously once to obtain the difference between the maximum and minimum readings of a micrometer. The gap between the lower blade and the bottom plane of the mixing chamber is measured by rotating the lower blade and the main shaft intermittently. A feeler gauge is used to measure the gap within the lower blade's plane to the bottom plane of the mixing chamber.

5. The stirrer's impeller rotational speed is measured using a tachometer to determine the main shaft's speed.

6. Mixing Time: Record the mixing time of the material in the mixing chamber using a stopwatch.
