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.

How to ensure the sand mill grinding material quality problems

Sand mill in the grinding process is prone to grinding color paste does not meet the requirements of the phenomenon, will bring us a waste of resources. In order to meet the needs of users, grinding color slurry constantly find out the reasons from the actual operation, so that the fineness of grinding color slurry meets the requirements and improves the work efficiency. Therefore, we analyze the reasons and solutions by analyzing the reasons for grinding color paste not meeting the requirements. The reasons why sand mill grinding color paste does not meet the requirements are as follows. 1、The fineness of the pigment itself is larger than the fineness required by the color paste and cannot be refined. In most cases, the original particle size of the pigment is larger than the fineness required by the color paste. Solution: Process and crush the pigment further to make its particle size below the fineness required by the color paste, because the dispersing process of the color paste grinding can not solve the problem of further reducing the original particles. 2、High content of pigment impurities, which can not be refined, such as mixing paint skin, fiber, dust, fine sand and other impurities. Solution: Firstly, we should rely on the pigment supply department to strengthen the management, forbid mixing the impurities and ensure the product quality; Secondly, when pairing color paste production workshop, strengthen the paint filtration, pay attention to the timely removal of identifiable impurities in the powder; when the mixed impurities are dispersed in the three drums, the full bucket, the remaining bucket operation or the single roller mill tandem should be adopted to make full use of its filtration function.

How to avoid sand mill screen clogging

Sand mill is widely used in industrial production, which can finely grind and screen various materials to improve production efficiency. However, sometimes the screen of the sand mill will be blocked by the material, which will affect its normal operation and reduce the working efficiency. In order to prevent this situation, we can take some measures. First of all, it is very important to reasonably choose the specification and material of the screen mesh. According to the required grinding and screening effect, choose the appropriate screen mesh aperture and mesh shape. At the same time, the material of the screen mesh should also have wear resistance and corrosion resistance to ensure a long service life. The right screen specification and material can effectively avoid screen clogging problems. Secondly, make sure that the sand mill is fed evenly. Different materials have different fluidity and adhesion, if the feed is not uniform, it is easy to lead to screen clogging. Therefore, if you configure appropriate infusion equipment at the feed opening, you can make the material evenly distributed on the screen, thus reducing the chances of clogging.

The correct working process of high shear emulsifier

High shear emulsifier is designed for mass production, using claw bite, double and suction structure, to avoid the dead space and vortex phenomenon caused by the upper part of the material is difficult to inhale. The shear force of the equipment is stronger, thus the production efficiency and dispersing emulsification quality are improved. When the external energy input, the two materials reorganize into a homogeneous phase. Due to the high tangential speed generated by high-speed rotor rotation and high-frequency mechanical effects brought about by the strong kinetic energy, so that the material in the stator and rotor narrow gap by a strong mechanical and hydraulic shear, centrifugal extrusion, liquid layer friction and turbulence and other integrated effects, the formation of suspensions (solids/liquids), emulsions and foams. Thus the immiscible solid phase, liquid phase, gas phase in the corresponding mature technology and the appropriate amount of additives under the joint action, instant uniform fine dispersion emulsification, after high-frequency cycle, to obtain stable high-quality products.

How to fill the grinding media of horizontal sand mill?

First, the horizontal sand mill media and its loading:Horizontal sand mill can be used glass balls, zirconia balls, steel balls for grinding media, each medium is better to use a uniform particle size before loading into the cylinder media should be cleaned beforehand, screening. Grinding with a certain media according to the dispersion of the material to be ground fineness and viscosity to choose. The principle is: the harder the material should be followed by the selection of harder media; product requirements, the finer the media particle size and filling volume should be increased accordingly; be ground material particle size is coarse, the selection of media particle size should be coarse. Horizontal sand mill grinding media loading is about 85% 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.

What if the stainless steel reactor is not hot enough?

Stainless steel reactor temperature is not enough may be caused by a variety of factors, the following list of several common situations and the corresponding solutions. 1、Insufficient heating rate: If the heating rate is insufficient, then the temperature of the reactor will rise very slowly. In this case, the temperature can be increased by increasing the heating power or extending the heating time. 2, Improper heating medium: the heating medium will also affect the reactor temperature. For example, if the medium used has low transfer efficiency, the temperature of the reactor will rise slowly. You can choose a better heating medium or replace the heating method to try. 3, Control system failure: sometimes, the control system of the stainless steel reactor may fail, resulting in unstable temperature in the kettle or unable to reach the set value. You can check whether the control system is working properly and try to readjust the control parameters.

Influence of grinding beads on the grinding efficiency of sanding machines

The impact of grinding beads on the grinding efficiency of the sanding machine is mainly reflected in the following aspects: 1, Grinding bead particle size and surface finish The size of the grinding bead determines the contact point between the grinding bead and the material. The smaller the particle size of the beads in the same volume the more contact points, the higher the theoretical grinding efficiency, but this is relative. When grinding materials with large initial particles, for example, for a 100 micron slurry, smaller particle size beads may not be usable because the impulse of a small bead does not fully grind and disperse the energy. In this case, a bead with a larger particle size should be used. For the same material, the wear rate is directly proportional to the surface finish of the grinding media, so the surface smoothness of the grinding media is needed to reduce the wear rate. While grinding and pulverizing the material, the grinding beads will also have abrasion, and the abraded grinding beads will be difficult to separate after mixing with the slurry, which will affect the product quality. Therefore, generally speaking, the smoother the surface of the grinding beads, the better.
