Factors affecting the effectiveness of the disperser

High-speed disperser equipment plays an important role in the modern industrial equipment mixing system and mixing, especially in solid-liquid mixing, liquid-liquid mixing, oil-water emulsification, dispersion of uniformity and so on has a very important application, shear milling is through the high-speed mixing and mixing, grinding, shear, homogeneous formation of uniformity of mixing. If you want to analyze the performance and characteristics of high-speed disperser, you need to understand the dispersing effect of the disperser materials affect several factors: 1. The form of dispersing head mainly has intermittent and continuous type (continuous type is better than batch type). 2. The shear rate of the dispersing head (the higher the shear rate, the better the effect) 3. The tooth structure of the dispersing head (divided into primary teeth, medium teeth, fine teeth and ultra-fine teeth, the finer the effect, the better)

What is the temperature resistance of stainless steel reactors?

Stainless steel reactor is a kind of commonly used chemical equipment, which is widely used in various chemical reaction processes due to its good corrosion resistance and high strength. The temperature resistance range of stainless steel reactor is affected by the selection of its material and manufacturing process, which will be introduced in detail below. The material of stainless steel reactor is mainly stainless steel, common 304, 316, 316L and so on. These stainless steel materials have different temperature resistance ranges, of which 304 stainless steel is suitable for chemical reactions at temperatures not exceeding 80 ℃, 316, 316L stainless steel is suitable for chemical reactions at temperatures not exceeding 120 ℃. Therefore, the temperature resistance range of the stainless steel reactor mainly depends on the material selected.

Working principle of high speed disperser

High-speed disperser is a kind of equipment widely used in chemical industry, food and medicine, etc. Its principle is to disperse materials rapidly, mix them evenly or disperse them quickly by the action of shear force and suction force produced by the high-speed rotating blade and high-speed fluid. High-speed disperser is mainly composed of motor, transmission, drive shaft and disperser. The motor drives the transmission shaft to rotate through the transmission, and the transmission shaft is connected to the disperser. The disperser is equipped with several blades, the number and shape of which will affect the dispersing effect. When working, the material is added into the disperser, the motor is started, and the speed of the transmission shaft is adjusted so that its rotating speed reaches the required dispersing effect. The materials are instantly dispersed, mixed or scattered under the action of the rotating blades and high-speed fluid.

Key factors affecting grinding fineness in sand mills

Sand mill grinding fineness is an important indicator of sand mill processing effect, which determines the quality of processed products. However, to achieve the sand mill grinding fineness we want is not an easy thing, this article will discuss several key factors that affect the sand mill grinding fineness. First, the sand mill processing medium Sand mill processing medium determines the processing material and grinding method. Different processing media will have a different impact on the fineness of grinding. Such as grinding wheel particle size, composition and hardness, lubricant lubrication status and so on will have an impact on the grinding fineness of the sand mill. Second, grinding strength Grinding strength directly affects the size of the grinding fineness of the sand mill, but also affects the service life of the grinding equipment. Such as excessive use of strength in grinding, may damage the grinding equipment; and grinding strength is not enough, may lead to poor grinding results.

Introduction to the installation steps of stainless steel reactor

Any equipment needs to be installed before use, so the stainless steel reactor is no exception, however, the correct installation steps, not only to promote the use of equipment, but also to reduce equipment damage, the following is said to be the specific installation steps. 1、Handling: when handling, only allow the tank ear to be stressed, do not allow rolling and pry bar, avoid vibration, collision, is strictly prohibited to take over the pipe clamps, clamps and other vulnerable parts of the force. 2、Hoisting:the rope must be hung on the specified part, not touching with any object, and put it down gently and steadily. 3、Pre-installation inspection: before assembly, the inspector should wear clean soft-soled rubber shoes to enter the container to check the glass-lined layer for any abnormality.

Stainless steel reactor should be regularly checked items

Stainless steel reactors need to be inspected regularly. The regular inspection of the running reactor, including external inspection, internal and external inspection and inspection of three kinds. First, the main contents of the external inspection are: the external surface of the kettle body has no cracks, deformation, leakage, local overheating and other abnormal phenomena; safety accessories are not complete, sensitive, reliable; fastening bolts are not intact, all tightened; foundation has no sinking, tilting, and anti-corrosion layer damage and other abnormal phenomena. The inspector's work is mainly responsible for the external inspection of stainless steel reactor, but also the operator's inspection tour and daily inspection of a content. Vessel inspectors of the external inspection should be carried out at least once a year.

What are the properties of nano sand mill

Nano sand mill adopts material pump to send the solid-liquid mixture material which is pre-dispersed and wetted by the mixer into the cylinder, which can realize the continuous processing and continuous discharging of the material and greatly improve the production efficiency. Nano sand mill is suitable for the dispersion of various viscosity products and the grinding of nanoscale materials. According to its processing performance, nano sand mill can be applied to rough processing in addition to mechanical finishing. For example, deburring of certain plate and disk-shaped porous parts, rough surface treatment of certain powder die castings before use to remove surface fretting and dents, as well as non-magnetic parts, stainless steel and some non-ferrous metal parts, etc. As the electromagnetic suction cup of the grinder can not be sucked, and can not be processed in multiple parts, the nano-sander is used to grind the blanks for rough processing of large-size blanks and some rough maintenance work. Nano sand mill performance: 1, Energy ratio: nano sand mill adopts a new type of rod and pin grinding rotor, so that the nano sand mill can concentrate kinetic energy, thus giving the grinding bead energy ratio. It can effectively improve the grinding efficiency and fineness, and at the same time reduce the resistance of the material in the grinding chamber, which is suitable for materials with medium and high viscosity and ultra-fine requirements. 2、Omni-directional cooling: adopting internal threaded guide type cylinder cooling method, plus double cooling of the top cover, the heat dissipation efficiency is 2-3 times of the traditional sand mill, to ensure the effective distribution of heat inside the sand mill. 3, Lengthened bearing seat: integrated machining process annealed to eliminate welding stress, deep machining formed by the boring machine, to solve the nano-sander bearing bit caused by the spindle jump, affecting the stability and service life of the problem.

Henan Wanda talks about how to choose the disperser

A disperser is a highly efficient device that can quickly break up powdered materials and distribute and wet them evenly in a liquid. Sometimes high speed disperser can also be used to dissolve soluble solids in liquid. At present, the disperser is widely used in coating, ink, medicine, adhesive and other industries.        The disperser consists of two parts: the motor and the dispersing head, which consists of the motor rotor. The dispersing head is connected to the motor, which drives the motor rotor and rotates at a high speed. Raw materials are subjected to obvious mechanical equipment and hydraulic drive cutting, filtering and extrusion molding, liquid layer friction, collision tearing and seepage and other comprehensive effects in the narrow gap in the middle of the stator motor rotor, so that the raw materials are sufficiently dispersed emulsion homogeneous.
