Grinding bead mill mainly depends on the grinding media and material between the high-speed rotating role for grinding work. A grinding bead mill is also called a sand mill. According to the external form, The equipment is mainly can be divided into vertical bead mill and horizontal bead mill.

Not only external difference? Let's Learn what is the difference between them in performance.

First of all, Vertical sand mill due to avoid sealing problems, easy to manufacture, low cost. So vertical sanding machine is more suitable for some fewer requirements product.

If you need high-quality product manufacturing. Horizontal sand mill manufacturing instead is quite a good choice .even costs more, but it can ensure the sealing material and prevent contamination of the product, And good enough to ensure the purity of the product. more suit some high requirements precision, fineness products.

Secondly, the Grinding media of the Vertical sand mill grinding chamber should be under the influence of gravity, Low medium filling rate and the distribution is not uniform So that there is no ideal grinding effect. But horizontal sand mill can be very good to overcome the gravity effect on medium, which has a good grinding effect, can meet the product requirements for fineness.

Third, we come from cost comparison. The vertical grinding machine at the time of downtime, grinding medium in the bottom of the grinding chamber. Then, a boot, blade, and beads produced strong friction. Easy to broken bead events occur cause media beads is too concentrated.

Fourth, a Vertical sand mill is generally used ordinary materials, Horizontal sand mill generally chooses tungsten carbide metal materials.

Horizontal sand mill and vertical bead mill are different placed, due to the influence of gravity and made of different materials, produce a lot of different. However, they all have their place, customers, and marketing. A user only needs to understand the characteristics to better choose more suitable products.

The grinding media used for the two sand mills are different. Usually, the vertical sand mill will use 2-4mm glass beads while the horizontal sand mill will use a 0.8-3.0mm zirconia grinding bead. And this results in quite a different grinding effect. Firstly, the zirconia grinding bead is made of high hardness, high wear-resistance ceramic material, the wear rate, and bead consumption is relatively lower and thus to save the cost of the beads and will also save the time for beads changing and broken beads cleaning. Grinding media sizes of the horizontal sand mill could be 0.8mm with a high density of up to 6.3g/cm³. The finer size of the grinding bead could generate a larger shearing force and could cut the grind of the agglomerated particles sufficiently. Therefore, a horizontal sand mill could realize ultra-fine grinding. It is suitable for micro grinding, sub-nano grinding, and also nano grade grinding. But as for the vertical sand mill, limited by the grinding media and grinding cylinder direction, the vertical sand mill could only realize micro grade grinding.
