Dyno Mill Manufacturers For Sale

Sand mills, also known as bead mills, are mainly used for wet grinding of chemical liquid products and can be broadly divided into vertical bead mills, Dyno Mill Manufacturers and horizontal bead mills. Today we will discuss the basic features of these three kinds of sand mills together.

Dyno mill：

This is an APS Dyno Mill Manufacturers system, by pouring in grinding beads, lowering the Huadong cover and closing the grinding cup, the base material is ground; after finishing grinding, the sealing plug under the screen is removed and the base material flows out from the grinding cup under pressurized conditions, and the grinding medium is stopped in the cup.

✔️Dyno Mill Manufacturers Features:

• the more suitable volume ratio of grinding sample and grinding beads is about 1:1;

• the diameter of the screen is suitable for more than twice the beads, for example, 0.5mm screen is suitable for more than 1mm grinding beads;

• Teflon single-layer grinding disc for small sample volume; there are also double-layer, as well as three layers of non-concentric grinding disc shear force is greater, fast to get the grinding effect (<10min), while grinding disc loss, there may be metal particles off to the sample;

• the connection of compressed air is to turn the upper ring upward (built-in seal, so that the compressed air does not leak upward, downward squeeze out the sample);

• select the size of the sample jar and dispersion tray, you need to see the table below. For example, when the sample jar is 500ml, you need to choose the model of LC55 or above.

Basket bead mill：

Basket bead mill is a grinding basket which has been filled with grinding beads is lowered into the base material to grind, the fast rotating grinding disc inside the basket stirs the beads inside the basket for the grinding process, the dispersion disc, the basket and the patented built-in vane pump wheel produce extremely effective base material circulation, which helps to get the best grinding effect in a short time.

✔️Features:

• special flange is required for connection with the disperser (standard connector and machine need to buy an extra (quick) connector);

• the size of sieve hole and grinding beads should be more than 1:2;

• TML 1 for example, 2L sample jar put the sample capacity is about 1 ~ 1.25L;

• TML 1 for example, the capacity of the grinding chamber is 65ml, the amount of beads needed is 50-70%, you can choose about 40ml (60%);

• when the test is just started, when loading beads, you can manually rotate the basket to facilitate the entry of beads, then first slow speed (100rpm) to let the beads fully enter, slowly enter the sample, and expel the air around the beads by slow rotation;

• the particle size of the sample should be smaller than the diameter of the sieve, in order to smoothly flow out of the sieve, forming a "bottom-up" longitudinal reflux, in order to verify the reflux (and speed-related), you can lift the basket a little bit to the liquid surface to do observation;

• the most suitable dispersion speed: 8-14m/s; sometimes 10-16m/s, to make a balance between temperature, linear speed and torque.

Horizontal bead mill：

Horizontal bead mills include three different series of DISPERMAT® SL, RS5, RS10 bead mills.

✔️Features：

• the diameter of the screen (gap)*3≈the maximum diameter of the available beads, for example, if the gap is 0.4mm or more, the size of the beads must be 1.2mm or more;

• the amount of grinding beads (volume): about 80% of the grinding cavity, such as the SL12 grinding cavity is 125ml, the amount of grinding beads is 100ml;

• SL12 sample volume is 150~750ml, but the normal dosage is 300~600ml;

• It must use and sample corresponding cooling sealant (sealing liquid), and apply 2 bar pressure;
