Influence of feed rate on the operating efficiency of nano-sand mills
The impact of the feeding speed on the operating efficiency of the nano sand mill is mainly in the following aspects: 1, Grinding efficiency: feeding speed is too fast will lead to the grinding media to fully grind the material, thus affecting the grinding efficiency. Because the grinding sand on the material grinding role mainly depends on the grinding process of grinding sand and materials between the friction and shear force, feeding speed is too fast to make the friction and shear force to shorten the action time, resulting in a reduction in grinding efficiency. 2, Equipment load: feeding speed is too fast will lead to increased equipment load. Because the feed rate is too fast means that the unit time into the equipment of the material increased, and the processing capacity of the equipment is limited, beyond the processing capacity of the material will be piled up in the equipment, increasing the load of the equipment, may lead to equipment overload and shutdown.

What are the ways to regulate grinding pressure in a sand mill?
Sand mill in the grinding process, the appropriate increase in pressure can make the grinding efficiency increase, is conducive to obtain the required particle size in a shorter period of time. But the pressure is too large, it will lead to the grinding media wear rate is too large, make the sand mill and other depreciation rate increased. So how to maintain a proper balance between higher grinding efficiency in the grinding process and avoiding the problem of high grinding pressure leading to high wear rate of grinding media is particularly important. So what are the ways to adjust the grinding pressure of the sand mill? First of all, the factors affecting the grinding pressure of the sand mill is the rotational speed of the sand mill, when the rotational speed is increased, the collision between the material and the grinding media, shear force will increase significantly, the internal material between the extrusion and compression are also frequent, and at the same time, a higher rotational speed will allow the material to pass through the rate is reduced, which significantly increases the cylinder pressure of the entire grinding cylinder.

High-speed disperser design features and selection highlights
High-speed disperser is powerful enough to mix, disperse, homogenise and emulsify materials, and it only takes a short working time to disperse and emulsify the materials that need to be processed immediately, and then get stable and high-quality products through high-frequency circulation. Vertical design of disperser makes all materials enter into the dispersing chamber, which meets the requirements of hydrodynamics and improves its working efficiency. Low outlet discharge design meets the production requirements. Vertical pressure makes the machine work more stable and easy to clean at the same time. Under the premise of combining the relevant standards, according to the production requirements, all materials in contact with materials in the high-speed disperser are made of SUS201 or 3304 steel or above acid- and alkali-resistant Hastelloy, which greatly improves its abrasion resistance and corrosion resistance, and prevents contamination caused by physical and chemical changes in the equipment and materials.

How to use the grinding media in a sand mill correctly?
Sand mill media and its filling amount: sand mill can use glass balls, zirconia balls and steel balls as grinding media. Each media selection of uniform particle size media is good, and should be cleaned and screened in advance before putting into the cylinder. In the grinding process, should be based on the dispersion of grinding material fineness and viscosity to choose a certain media, the principle is: the harder the material, should choose the harder the media; product requirements, the finer the media particle size, the finer the filling volume should be increased accordingly; grinding material particle size, the coarser the media particle size, the coarser. Sand mill grinding media filling is about 90% of the cylinder volume, the specific should be loaded how much, according to the particle size of the media, the material's sensitivity to temperature, as well as material varieties and other factors to determine.

How to adjust the processing temperature of high shear emulsifier
High shear emulsifier is a key equipment widely used in cosmetic, food, pharmaceutical and other industries, which, through high-speed shear and emulsification, mixes multi-phase materials evenly and improves product quality. In the process, accurate adjustment of the processing temperature, both to help maintain the stability of the emulsified material, but also to improve the product yield and quality. In high shear emulsifiers, the processing temperature plays an important role in the viscosity, fluidity and interaction of materials in the emulsification process. Appropriate processing temperature helps to promote compatibility of emulsified materials, improve solubility and reduce viscosity, and also ensures the stability and durability of the product. Excessively high or low temperatures may lead to product quality degradation, such as incomplete emulsification, separation, bubble generation and other problems.

How to select the support seat of stainless steel reactor
Stainless steel reaction kettle and other chemical machinery and equipment support has two kinds of support lugs and legs, the customer in the order usually ignored check this point, although the selection of support is particularly important, because the overall equipment for how to place the use of how to use with the rest of the equipment supporting the use of other equipment, which is particularly important. The next step is to introduce how to select the support seat of stainless steel reactor? In principle, usually pick lug support, that is, in the jacket part of the upper end of the welded lug-type support, is a suspended support, so good with the rest of the equipment such as condensers, piping, tanks, etc. supporting the use of picking lug support to have an operating table, the design of the operating table is based on the specifications of the kettle, with the channel steel, pipe, etc. Composition, according to the process of the rest of the supporting equipment is also conducive to the installation of the operation;

How temperature affects the disperser
In the existing equipment, the grinder and disperser are mostly two kinds of equipment with independent functions. The material after grinding needs to be dispersed through another process, which seriously affects the efficiency of the equipment. Moreover, for different viscosity materials in the grinding and dispersing process, the flow range is wide, there are static and dynamic grinding body and grinding materials in the grinding process heat, poor heat dissipation performance and other issues. At high speed, the high speed rotation of the cutter generates strong shear force, and the material generates heat, which raises the temperature inside the tank. When processing liquids, the temperature rise should be stopped so that the jacket can be used. Indeed, if too little heat is generated, the disperser may be considered to be operating inefficiently or poorly dispersed. However, an increase in the temperature of the slurry can have a number of detrimental effects; the temperature rise, even if small, can greatly reduce the viscosity of the material and turn laminar flow into turbulence, and the kinetic energy of this turbulence is immediately converted into heat, resulting in an undesirable temperature rise.

Sand Mill Lubricant Selection to Consider
Select the sand mill lubricant, to seriously understand the specifics of the situation, because different lubricants can play a role will be very different, if we can seriously do a good job in these aspects of the choice, the next to be able to play a better role, but a lot of people in the decision-making process, in fact, is not clear which of these aspects, so it will affect the entire lubrication work. 1, Consider the processing of materials Different equipment in the selection of lubricants, and we also need to take into account the specific processing of materials, because the processing of each material, the degree of coarseness and fineness of which there will be a relatively large difference, and thus the use of equipment in the process of some of his processing will become different, so take into account the differences in these materials, and then be able to make a better choice. 2, Pay attention to the viscosity of the lubricant Each different sand mill lubricant, when making a choice, should also look at the specific annual, if those viscosity lubricant, in the process of using the lubricant is not able to protect the work efficiency, and may have a negative impact, so we make a choice, we should buy the viscosity of the lubricant, so as to be able to play a very good effect.

Types and selection of reactor agitators
Reactor stirrer a good selection method is good to have two conditions, one is to choose the results are reasonable, the second is to choose a simple method, but these two points are often difficult to have at the same time. Since the viscosity of the liquid has a great influence on the mixing state, it is a basic method to select the type according to the viscosity size of the mixing medium. Several typical agitators have different ranges of use depending on the viscosity. With the increasing viscosity of the various agitators used in the order of propulsion, turbine, slurry, anchor and belt type, etc., where the propulsion of the finer points, proposed a large volume of liquid with a low rotational speed, the small volume of liquid with a high rotational speed. This selection chart is not a restriction on the use of slurry type, in fact, the use of various types of slurry type range of overlap, for example, slurry type due to its simple structure, with the baffle can improve the flow pattern, so in the low-viscosity is also more commonly used. And turbine type due to its convection circulation ability, turbulence diffusion and shear are stronger, almost a wide range of applications of a slurry type.
