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.

Common clogging problems of nano sand mill

Nano sand mill in the production process, due to valve clogging, often need to stop the machine to clean, many operators often do not know how to clean themselves. In fact, the valve clogging of the sand mill is a common failure, and the maintenance method is relatively simple. The general operators have to learn that they can repair the problem themselves when it occurs, so as to avoid delaying the production needs.      1,When the common valve is used to regulate some media which are easy to settle and contain some solid particles, it is often clogged at the throttling port and guide, and gas and steam can be connected to the bottom of the lower bonnet. When the valve is clogged or stuck, opening the external gas or the valve with steam can complete the flushing work without moving the regulating valve and make the valve operate normally.

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.
