Grain processed into a variety of powder finished product process, the mixed raw materials clean-up without a net, or due to mechanical wear and other reasons, resulting in the finished product magnetic impurities of metal objects, these tiny metal impurities with the food ingested, would cause harm to humans, affecting their health, national standards have a strict limit (allowing less than 0.003g/kg); the same time, the magnetic metals the level of content, assessment powder to produce one of the important indicators of the process.
JJCC magnetic metal detector board with high-magnetic metal production process of magnetic separation processing.
The separator plate during use should pay attention to the following question:
1. separation of a mixture of plate separation of magnetic metals and residual sample, magnetic separation board area;
2. White collection of magnetic metals and residual sample mixture on the magnetic area of the separator plate, (Note: paper and magnetic board must have a full contact); then pulled a white edge gently back and forth pulling, magnetic metals and residual sample mixture in magnetic metals and magnetic plate full access;
3. With ear cleaning ball perpendicular to the magnetic metals and residual sample mixture 10cm height of a slight blow, so that the accumulation of a mixture of as much as possible to spread the powder layer is thinner and more conducive to magnetic metals with magnetic board full access;
4. Ear cleaning ball to blow off the residual sample in the mixture, carefully light winds, and careful observation, to prevent bad contact with the magnetic board magnetic metals and residual sample at the same time blowing abandoned;
5. The magnetic metals have been separated from the white paper, carefully transferred to a weighing paper, and again on the magnetic board magnetic area, gently pull dynamic weighing paper, and carefully check that whether there are remnants of the sample particles (in the case of weighing paper and magnetic plate full contact can also be used to wash the ear with a ball and then gently blow it again), after the separation of clean and make sure that to the magnetic metal objects weighing paper together weighing.
Magnetic separation plate in the JJCC magnetic metal detector before and after use, should note the following:
1. Separation plate to avoid contact and mobile phones, watches, magnetic cards, magnetic items;
2. The separation plate away from the laboratory other electronic apparatus, equipment, such as electronic scales, computers, etc.;
3. Separation board is a fragile items should be gently put, is strictly prohibited tap, touch and fell;
4. Storage sites should be independent and to maintain a clean, away from other magnetic metals, to avoid mutual adsorption;
5. To ensure high magnetic separator plate and durability, extended service life, the separation plate should be at room temperature storage to save.
