What Are the Application Scenarios of a High-Speed Mixer in Plastic Processing?

There are indeed many intricate steps in plastic processing, and one of the most important steps is efficient mixing. This is critical to ensure the quality of the output. BXKM is an equipment manufacturer specializing in building high-performance, high-speed mixers specifically for plastic processing, has been featured on the site, https://www.bxkm.com/. These mixers are great for any stage of plastic processing because they use high-speed rotating blades to create high cutting, stirring, and dispersing forces. In this article, we will showcase the application of BXKM high-speed mixers in plastic processing and the improvement in processing efficiency and product quality offered to businesses.  

High Speed Mixer for Raw Material Premixing in Plastic Granulation  

Plastic granulation is the foundation of plastic processing. This is the stage where the raw materials are mixed, and the uniformity and quality of the end product is determined. This is where high-speed mixers are most beneficial. In plastic granulation, the primary resins like PP, PE, and PVC combine, along with the other additives, to form the plastic mass that will then be granulated. Before the actual granulation, the. additives. with plasticizers, stabilizers, colorants, and fillers should be completely mixed with the resins. BXKM high-speed mixers are effective in this task because the mixers use high-speed blades to break agglomerates, and the heat that is created will helps some additives and resins form a bond. This will form a strong base for the granulation that is to follow.

For instance, while making colored plastic granules, a high-speed mixer uniformly disperses colorants in the resin. This prevents the granules from having color streaks or uneven color distribution. BXKM’s high-speed mixers have temperature control functions to help maintain the quality of premixed materials by preventing excessive heat from degrading materials during the mixing process. 

Plastic Modification Processing

Plastic modifications improve the performance of plastic materials by adding strategic modifiers. A high-speed mixer also becomes integral equipment for this scenario. During the modification process, the dispersing of modifiers like glass fibers, carbon black, and flame retardants into the plastic matrix is critical for the modifiers to have impact. BXKM’s high-speed mixer has strong dispersing capabilities; the patented blade design creates turbulent flow within the mixing chamber to break down the agglomeration of modifiers and distribute them evenly within the resin. For example, while producing flame-retardant plastics, a high-speed mixer guarantees that the flame retardants are uniformly distributed within the plastic resins to ensure consistent performance in flame-retardant behavior across every part of the finished plastic product.

BXKM customizes high-speed mixers based on different modification needs. For example, BXKM can modify a mixer by increasing the mixing chamber volume for large-batch modification, or adding a vacuum device for moisture removal. This modification will maximize the enhancement effect.  

Preparation of Plastic Masterbatches  

Preparing plastic masterbatches (color masterbatches, filler masterbatches, or functional masterbatches) requires a high-speed mixer due to the high concentration of additives that needs uniform dispersion. In masterbatch preparation, one must first mix a large amount of additives with a small amount of carrier resin and then granulate it. This mixing task can be accomplished efficiently by a high-speed mixer, as the velocity of the mixer leads to the creation of strong shear forces which aids in the mixing of additives and carrier resin and also aids in the grinding down of large particles of additives to smaller ones. This concentration and uniformity of the masterbatch improves. For example, in the production of color masterbatches, a high-speed mixer guarantees that high-concentration colorants are fully integrated with the carrier resin, necessitating the use of only a small amount of the color masterbatch to achieve the desired effect, when mixing with raw resins afterward.

BXKM makes high-speed mixers with an accurate high-speed mixing Maestro system. It makes total customization possible so BXKM makes predetermined mixing speeds for each masterbatch, attaining the ideal blending without distorting the material. 

Evaporation of Moisture and Volatile Matter from Plastic during Hygroscopic Condition. 

During storage, several plastic materials such as PET, PA and PC attract moisture. If moisture content is present before the processing cycle, bubbles, cracks and "silver" lines will be the least of the defects that will result. Drying of plastic materials is a key scenario where high-speed mixers are used. BXKM high-speed mixers takes advantage of the heat mixing Hutchinson friction generates, both in the materials and the mixing wall chamber, to evaporate moisture in plastic. Simultaneously, the blades rotate and warm the materials so that each section is uniformly heated to avoid extremes of overheating and underheating. For instance, a high-speed mixer is capable of extracting moisture from PET pellets to be processed into PET plastic bottles and sheets and will guarantee the final product's transparency and strength.

BXKM mixers come with a venting device option to discharge evaporated moisture and volatile matter on time, thus further enhancing drying efficiency. 

Mxg Recycled Plastic Materials  
With the promotion of environmental stances, the recycling and reuse of waste plastics has become an integral part of plastic processing. Recycled plastic materials often have impurities, different types of plastic fragments, and residual additives, so high-speed mixers are required. BXKM high-speed mixers integrate, homogenize, and mix recycled plastic fragments with new resins or modifiers to offer great uniformity of the recycled plastic mixture to reduce the size of large plastic blocks. For example, recycled PP plastic is processed into plastic buckets, and a high-speed mixer combines recycled PP fragments with a new PP resin and stabilizers so that the plastic buckets perform as required during use. HXKM high-speed mixers have wear-resistant mixing chambers and blades, which means the equipment will last longer as the blades will withstand the abrasion of impurities in recycled materials.

Coating and Surface Treatment of Plastic Particles  

Sometimes, there is a need for a functional layer (anti-blocking agents, slip agents and antistatic agents) to be added to the surface of plastic particles for improving processing and product functionality. For such scenarios, a high-speed mixer is appropriate. Surface treatment by a high-speed mixer from BXKM is effective due to the even distribution of functional materials. The high-speed rotating blades and plastic particles moving at high speed ensures a high rate of functional material (powder or liquid) application that is sprayed into the mixing chamber, coating the surface under centrifugal and shearing force. For instance, high-speed mixers used in the production of plastic films and coating surface plastic particles with anti-blocking agents during the production of films, prevents the films from sticking. BXKM’s high-speed mixer comes with a precise feeding system to control coating thickness and uniformly meet process requirements.
