The working principle and parameters of sand mill are introduced
Rucca sand mill is a kind of high efficiency, energy saving, environmental protection grinding equipment, widely used in various industrial fields.Its operating parameters have a very important impact on the grinding effect and equipment performance.This paper will start with the operating parameters of Rucca sand mill, and introduce the influence and function of each parameter in detail, as well as the specific introduction of parameters.
First, the line speed of the sand mill
Linear velocity is an important parameter of Rucca sand mill, which affects grinding efficiency, material fineness and equipment wear.
The linear velocity directly determines the strength of the kinetic energy exerted by the grinding medium on the material particles.
Under normal circumstances, the line speed range of the sand mill is between 8-16m/s.
If the linear speed is too low, the friction between the grinding medium and the material particles will be reduced, resulting in reduced grinding efficiency;
If the line speed is too high, it will cause the fineness of the material to become smaller, and it will also increase the wear of the equipment.
Therefore, choosing the right linear speed is very important to ensure the grinding effect and extend the service life of the equipment.
Second, the flow of the sand mill
Flow rate is another key operating parameter, which has a significant impact on both product fineness and yield.
In continuous grinding process, the absolute value of flow rate and yield is equal;
In cyclic grinding, the yield is 1/n of the flow rate (n is the number of cycles).
The control of flow rate mainly depends on the feed speed and the structure of the sander.
Under the premise of ensuring the grinding effect, the production can be increased by increasing the flow rate appropriately.
However, too large or too small flow will have an adverse effect on the grinding effect, so it is necessary to make reasonable adjustments according to the actual situation.
Third, sand mill medium size, specific gravity, filling rate
1. Medium size
The grinding medium is an important part of the sand mill, and its size has a significant impact on the grinding efficiency and product fineness.
Generally speaking, a small grinding medium size can improve the fineness of the product, but too small a medium size may cause blockage of the outlet separator of the sander.
Therefore, it is very important to choose the appropriate medium size.
Under normal circumstances, the diameter of the grinding medium should be in proportion to the width of the separator gap of the sand mill, which is generally 2-4 times.
2. Medium proportion
The specific gravity of the medium also has a great influence on the grinding efficiency.
The greater the specific gravity, the greater the kinetic energy and the higher the grinding efficiency.
In the production of offset printing ink, generally use a diameter of 1.6-2.5mm steel ball;
The abrasive inkjet ink uses zirconia beads with a diameter of 0.3-0.8mm.
Therefore, in actual production, the appropriate medium proportion should be selected according to different product needs.
3. Filling rate
The filling rate of the grinding medium refers to the filling degree of the grinding medium in the sanding mill.
The filling rate of Rucca sand mill will vary according to different models and grinding needs, generally between 75% and 95%.
High filling rate may lead to high temperature rise of the sander or blockage of the outlet;
If the filling rate is too low, it will reduce the grinding efficiency and increase the wear and grinding time.
Therefore, reasonable control of the filling rate of the grinding medium is very important to ensure the grinding effect and the normal operation of the equipment.
Forth, Summary
The running parameters are the key factors that affect the performance and grinding effect of Rucca sand mill.
In actual production, the parameters such as linear speed, flow rate, medium size, specific gravity and filling rate of the sand mill need to be reasonably adjusted according to product characteristics and production requirements.
By optimizing these parameters, you can improve grinding efficiency, reduce energy consumption and wear, thereby extending the service life of the equipment and improving production efficiency.
