How to screen the raw materials for olive oil glass bottles?

1. The particles required for different raw materials are different, and the mesh used for sieving is also different. Jingxian sieving can only control the upper limit of raw material particle size, and cannot separate the small particles.

2. After crushing quartz sand and various raw materials, they must be sieved to separate impurities and large particles, so that they have a certain particle composition to ensure uniform mixing and layering of the batch.

3. The commonly used screening equipment in drunken cotton glass factories includes hexagonal screens (rotary screens), vibrating screens, and shaking screens. Particle classification can also be carried out using a wind centrifuge.

4. The particle size of raw materials is considered based on the density of the raw materials, the amount of raw materials in the batch, and the given melting temperature. Yuanbao silica sand usually only passes through a 36-49 well cm2 sieve. Because the particle composition of silica sand has been analyzed when selecting it, the purpose of sieving after entering the factory is not to control its particles, but to remove foreign soft sandstone, quartzite, feldspar, etc. such as weeds, stones, and mud blocks, and to purify and reduce nitrate, limestone, and dolomite through 81 Lcm2 sieves, and 64 Lcm2 sieves.
