Pipeline type colloid mills are divided into JM-W dispersion fine grinding pump and JP-W high-speed mixing homogenization grinding pump. Then, dispersion fine grinding pump is referred to as grinding pump for short, and another type of high-speed mixing homogenization grinding pump is referred to as grinding pump for short.
Pipeline type colloid grinding machines are divided into two major types, JM-W dispersion fine grinding pump and JP-W high-speed mixing homogenization grinding pump. Therefore, dispersion fine grinding pump is referred to as grinding pump for short, and another type of high-speed mixing homogenization grinding pump is referred to as grinding pump for short. The main reason is that the internal structure and performance differ greatly while the product name is different.
The working principle is composed of a motor, a pump holder, a coupling, a dynamic and static grinding plate, a pipeline type inlet flange, an outlet method, and a machine base. Grinding machines such as online high-speed multi-stage high cutting, dispersion, mixing, depolymerization, pulping, homogenization, grinding, and grinding, supplemented by pump delivery, can be integrated with intelligent flexible automation to become a continuously operating new type of 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 with particle adhesion and high energy consumption during processing. Large domestic titanium dioxide and carbon black manufacturers have adopted imported rod sanders for back-end refining, but most of them are imported equipment, which has shortcomings in terms of high prices and after-sales services, as well as high energy consumption, Therefore, it is necessary to carry out preliminary pretreatment or direct alternative use to reduce energy consumption and reduce costs.
In order to solve this problem, we started to develop a pipeline type colloid grinder - formerly known as: multi-function grinder, pipeline type grinding pump, using special dynamic and static grinding body components, pump body integration structure, and other features. The pump can operate continuously online, environmental protection and energy conservation, low maintenance rate, low friction power consumption, strong wear resistance, and small dispersion fineness. It can greatly reduce production costs and expenses, and has uniform particles, convenient cleaning and color change, and no grinding impurities. At the same time, a number of patent technologies have been applied for. In terms of mechanical performance, the grinding pump has features and advantages such as compact structure, small size, low noise, and good results.
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 uses titanium dioxide colloid mill pipeline grinding pump for dispersion, coating, refining 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 into the mixer for pulping, screw pump transmission through the filter pipe, white carbon black pipeline grinding pump to fully shear, disperse, mix, depolymerize, crush, grind into micron particle fluid slurry, and then spray the finished products. 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, tanning, polymer materials, molecular sieves, catalysts, defoaming agents, composite water-soluble fertilizers, humic acid, fish paste, shrimp paste, protein feed, lubricating synthetic grease, lithium battery base material, iron phosphate battery paste, graphene, etc. have been launched in China, requiring precision mechanical equipment for high-speed shearing, dispersing, mixing, crushing, and grinding to achieve the desired results. Therefore, HAOXING Machinery has been committed to the design, research, development, and production of such mechanical equipment.
The linear speed of this pump is higher than 30-45m/s, and the shearing gap is very small. As the material passes through, the shearing mixing, dispersion, crushing, and grinding abilities of the circular vortex formed are relatively intense. Under the action of the propulsion device of the pump, the slurry in question first generates a negative pressure suction force of -0.1-2MPa, which sucks the processed material into the middle of the gap between the three-stage internal gear type dynamic grinding disk and the three-stage external gear ring static grinding disk for multi-level dispersion grinding. The core device performs high-speed shearing, pulsating vibration frequency, and turbulent complex forces, and relatively staggered tooth and groove movement. During each stage, the direction and pulsating process change. High speed shearing, dispersion, mixing, depolymerization, and homogenization occur Beating, grinding, crushing, and pump delivery 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 discs or adjusting flanges to control the discharge fineness of the grinding pump and the pump output pressure (lift). The smaller the gap, the finer the fineness and the lower the outlet pressure, the lower the lift; On the contrary, the larger the clearance, the coarser the fineness and the higher the outlet pressure, the higher the lift; Therefore, many customers are asking, what is the lift? Required lift
In addition, there is a JPW type high-efficiency shear mixing homogenization grinding pump JMW series (hereinafter referred to as "grinding pump"), which is developed into a first stage high-speed mixing device based on different materials to be processed. The second stage is a prismatic angular tooth dispersion grinding system. Its structure is different from the grinding pump in terms of grinding precision capacity, and its operating linear speed is slightly lower. However, its mixing, conveying pressure, and lift are also one-third higher than those of a grinding pump. It can quickly combine solid materials with liquids, or several polymer liquids, and instantly shear at high speed. It has the performance of dispersing, mixing, homogenizing, and crushing to small particles. Its inlet can be designed with multiple feed ports and liquid inlet ports, achieving the effect of efficient mixing, homogenizing, and crushing.
In summary, JM-W/JP-W series products are specially designed to handle the production needs of cutting, depolymerizing, crushing, and grinding particles contained in fluid, colloid, semi paste, or paste materials, especially for those requiring good dispersion, homogenization, depolymerization, crushing, and grinding effects. JPW grinding and homogenizing pump adopts a four-blade high-speed propulsion homogenizer and four and six wings for mixed transportation. JMW fine pipeline grinding pump has three or four stages of staggered tooth opposed structure grinding rotor, matched with a precise stator cavity. It can achieve better dispersion, emulsification, crushing, homogenization, ultra-fine, depolymerization, wet grinding, crushing, online continuous pump delivery and other functions, especially as a good helper for filter cake refining and pulping.
The pump is made of high-quality stainless steel S304, S316, S2205, S904, CrMoV, HX2010, and other special alloy materials to form the core component grinding plate material. According to the special needs of users, it can be refined using corrosion resistant and wear-resistant stainless steel, or hard and wear-resistant alloy steel, with a hardness of HRC ≤ 62, and its service life is more than 5 times longer than the original model. The equipment has high strength properties such as corrosion resistance and wear resistance, and is designed with a water jet cooling mechanical seal device (patented technology). It can dry run without materials, without damaging the dynamic sealing performance and mechanical performance. It is widely used as a dedicated model for catalysts, polymers, synthesis aids, titanium dioxide, white carbon black, bioengineering, and pharmaceutical preparation. It is currently the first to replace imported grinding machines High shear emulsification machines or sand mills are used in various high-speed solid-liquid mixing, emulsification homogenization, dispersion crushing, filter cake beating, grinding, and chemical synthesis processes. Their production efficiency is several times that of similar products mentioned above. The machine has a wider range of applications and is adjustable. It can replace the operating burden of emulsification pumps, dispersion machines, roller grinding, and sand grinding processes, greatly reducing production costs, and has uniform particles Easy to clean and change colors, without grinding impurities. It is mainly used for materials that require high fineness, are difficult to grind, and are dispersed. It can completely replace three roller machines, homogenizers, and other equipment. The purpose is to more fully shear, depolymerize, disperse, homogenize, grind, and transport slurry to reduce viscosity, thereby achieving better performance.
