Release time:2023-03-17
Pipeline type colloid grinding machines are divided into two major types: JM-W dispersed fine grinding pump and JP-W high-speed mixed homogenization grinding pump. The dispersed fine grinding pump is referred to as the grinding pump, and another type of high-speed mixed homogenization grinding pump is referred to as the grinding pump. Mainly due to significant differences in internal structure and performance, and product names.

The working principle is composed of a motor, pump bracket, coupling, dynamic and static grinding plate, pipeline type inlet flange, outlet method, and machine base. The grinding machinery mainly consists of online high-speed multi-stage high cutting, dispersion, mixing, depolymerization, pulping, homogenization, grinding, and crushing of pipelines, and auxiliary transportation of pumps. It can be combined with intelligent flexible automatic integration to become a new type of continuous operation colloid grinding machine equipment. In order to change the use of roller mills and mixers in the preparation of titanium dioxide and white carbon black pulping, but there are problems such as particle adhesion and energy consumption during processing, there are large domestic titanium dioxide and carbon black manufacturers using imported rod sanders to refine the rear end, but most of them are imported equipment, and there are shortcomings in high prices and after-sales, and high energy consumption exists, Therefore, it is necessary to carry out preliminary pretreatment or direct replacement use to reduce energy consumption and reduce costs.

To solve this problem, we have started developing a pipeline type colloid grinding machine - formerly known as a multifunctional grinding machine, pipeline type grinding pump, which adopts special dynamic and static grinding components, and an integrated pump structure. The pump can operate continuously online, is environmentally friendly and energy-saving, has low maintenance rate, low friction power consumption, strong wear resistance, and small dispersion fineness. It can significantly reduce production costs and expenses, and has uniform particles, convenient cleaning and color changing, and no grinding impurities. At the same time, multiple patent technologies have been applied for, and the mechanical performance of the grinding pump has the characteristics and advantages of compact structure, small volume, low noise, and good effect.

Technical background: since 2005, foreign technology has been introduced to produce high-grade rutile modified titanium dioxide. The production process: concentrate is rolled, covered by dispersion tank, and desalting process is carried out with pipeline grinding pump of titanium dioxide colloid mill for dispersion, coating, refining and pulping, and then refined by sand mill (nanometer level), and spray drying.

From 2012 to 2014, domestic white carbon black silica also successively started to produce modified white carbon black. The production process: rinsing, filter pressing, filter cake heating water enters the mixer for pulping, screw pump is used to transport it through the filter pipe, and white carbon black pipeline grinding pump is used to fully shear, disperse, mix, depolymerize, crush and grind it into micron particle fluid slurry, and then spray the finished product. If the nano modified silica process is required, the finished product will be dried by sanding and spray.

Since 2013, new materials such as ABS resin, thermoplastic polyurethane, leather making, polymer materials, molecular sieve, catalyst, defoamer, compound water-soluble fertilizer, humic acid, fish soluble slurry, shrimp paste, protein feed, lubricating synthetic grease, lithium battery base material, iron phosphate battery slurry, graphene and so on have been launched in China, all of which need precision mechanical equipment for high-speed shearing, dispersion, mixing, crushing and grinding to achieve the desired effect. Therefore, Haoxing Machinery has been committed to the design, research and development, and production of such mechanical equipment.

The linear speed of this pump is higher than 30-45m/s, and the shear gap is very small. This way, when the material passes through, the shear mixing, dispersion, crushing, and grinding abilities of the circular vortex formed are more intense. The slurry in question is first subjected to a negative pressure suction of -0.1-2MPa under the action of the pump's propulsion device, which sucks the processed material to the middle of the gap between the three-stage internal gear type dynamic grinding disc and the three-stage external gear ring static grinding disc for multi-stage dispersed grinding. The core device undergoes high-speed shearing, jumping vibration frequency, and turbulent complex forces, with relatively staggered tooth slot motion. In each stage, the direction and jumping process change, and high-speed shearing, dispersion, mixing, depolymerization, and homogenization occur Beating, grinding, crushing, and pump transportation to meet various requirements of different industries. At the same time, the gap between the dynamic and static grinding discs of the pump can be randomly adjusted by adjusting the disc or adjusting the flange to control the discharge thickness and output pressure (head) of the grinding pump. The smaller the gap, the finer the fineness, and the lower the outlet pressure, the lower the head; On the contrary, the larger the gap, the coarser the fineness and the higher the outlet pressure, and the higher the lift; So, many customers are asking, what is the lift? Request lift

In addition, there is a JPW type high-efficiency shear mixing homogenization crushing pump JMW series (hereinafter referred to as the crushing pump), which is developed into a first stage high-speed mixing device based on different processed materials. The second stage is a prismatic angular tooth dispersion crushing system. Its structure is different from the grinding pump's crushing and grinding fine ability, and its operating line speed is slightly lower. However, its mixing, conveying pressure, and head are relatively one-third higher than those of grinding pumps. It can quickly shear solid materials with liquids or several polymer liquids at high speeds when combined, disperse, mix, homogenize, and crush small particles. Its inlet can be designed with multiple inlet ports and liquid inlet ports, achieving the effect of efficient mixing, homogenization, and crushing.

In summary, the JM-W/JP-W series products are specifically designed to handle the production needs of cutting, depolymerizing, crushing, and grinding particles in fluid, colloid, semi paste or paste materials, especially for those that require good dispersion, homogenization, depolymerization, crushing, and grinding effects. The JPW grinding homogenization pump adopts a four blade high-speed propulsion homogenizer and a four and six wing mixed conveying system. The JMW fine pipeline grinding pump has a three or four stage staggered tooth opposed structure grinding rotor, matched with a precision stator cavity. It can achieve better dispersion, emulsification, crushing, homogenization, ultrafine, depolymerization, wet grinding, crushing, online continuous pump transportation and other functions, especially as a good helper for filter cake pulping and pulping.

The pump is made of high-quality stainless steel S304, S316, S2205, S904, and special alloy materials such as CrMoV and HX2010 to form the core component grinding disc material. It can be refined with high hardness HRC ≤ 62 using corrosion-resistant and wear-resistant stainless steel or hard wear-resistant alloy steel according to user special needs, and its service life is more than 5 times longer than the original model. The equipment has high strength performance such as corrosion resistance and wear resistance, and is designed with a water jet cooling mechanical seal device (patented technology), which can be dry run without materials, without damaging the dynamic seal performance and mechanical performance. It is widely used as a special model for catalyst, macromolecule, synthetic aids, titanium dioxide, white carbon black, bioengineering, and pharmaceutical preparation, and it is the first to replace imported grinders High shear emulsification machines or sand mills are used in various high-speed solid-liquid mixing, emulsification homogenization, dispersion crushing, filter cake beating and grinding preparation, as well as chemical synthesis and other preparation processes. Their production efficiency is several times that of similar products mentioned above, and the machine has a wider range of adaptability and adjustability. It can replace the operating burden of emulsification pumps, dispersion machines, roller grinding, and sand grinding processes, greatly reducing production costs, and the particles are uniform Easy to clean and change colors, without grinding impurities. Mainly used for materials that require high fineness, are difficult to grind, and are dispersed. It can completely replace equipment such as three-roller machines and homogenizers, with the aim of more fully high-speed shearing, depolymerization, dispersion, homogenization, grinding, and conveying slurry to reduce viscosity and achieve better efficiency.
