Details of the classification and selection of sanding machines

The sand mill belongs to the wet ultra-fine grinding equipment, from the development of ball mill. Widely used in ink production process pigment dispersion and grinding. Sanding machines have the different classification, production of different types of ink, the use of sanding machine structure is also different. Probably follow the following rules: gravure ink production generally uses pin (5-50 liters) or disk sander (10-100 liters). Rotary offset ink is generally used vertical bar (5-130 liters) or horizontal disc sander (60-500 liters), and super high viscosity sheet-fed ink production often uses high energy density conical sander or three roller machine. Inkjet inks (inks and pigment solvent-based) generally use high energy density pin type (horizontal or vertical) and centrifugal turbine rotors. Do you know about the classification and selection of sanding machines? Next, follow small makeup to come together.

First classification,

1. According to the structure and shape of stirring shaft, it can be divided into disc type, bar type and bar-type (both convex block type);

2. According to the layout of the grinding cylinder, it can be divided into vertical and horizontal;

3. According to the volume of the barrel, it can be divided into the laboratory, small, medium, large and super large;

4. According to the separation method of the medium, it can be divided into static and dynamic separation sand grinder;

5. According to the energy density (installed power per unit volume), it can be divided into low/high energy density sander.

Second, the purchase of the sanding machine

1. The material of grinding barrel body: in the industry of sanding machine, there are many manufacturers grinding barrel body most are made of stainless steel, in the unembroidered steel is also divided into many kinds, the owner needs to confirm;

2. The material of grinding barrel rotor: in terms of the process of the sanding machine, there are mainly two kinds, one is disc type grinding disc, the second is rod pin type grinding barrel and rod pin type rotor. The grinding effect of the bar - pin - type sander is much more obvious than that of disc sander.

3. The separation device of materials and grinding muons (zirconium beads): in the horizontal sanding machine, the separation device of materials and grinding media is mainly used to separate the separation device, which is mainly composed of the static ring and moving ring.

4. Mechanical seal and cooling effect of equipment: whether there are leakage of mechanical seal, how many hours of service life. The key is to see that the mechanical seal circulating fluid is the solvent or water-soluble in the grinding material, to avoid the product in the production of product pollution accident, bringing unnecessary economic losses;

5. Production efficiency: whether the structure design is reasonable determines the production efficiency and product quality;

6. Operation: the main control part of the machine is very centralized and easy to operate;

7. Easy to change color, clean and replace zirconium beads: mainly to understand whether the grinding chamber is designed without dead corners and how the self-cleaning effect is;

8. Complete safety protection functions: the selection of the whole machine's electric material, quality safety, etc.

Today about the classification of sanding machine and sanding machine selection skills are introduced here, understand the sanding machine classification and selection skills, help you to choose the most suitable sanding machine faster and better.
