Plastics and Rubber Filler Solutions
Calcium carbonate, talc, kaolin, and other non-metallic mineral powders are the most widely used filler and modifier materials in the plastics and rubber industries. Our equipment can meet the functional requirements of fillers for matrix materials such as PVC, PS, EPS, XPS, and recycled plastics, providing a one-stop solution from ore crushing to ultrafine powder processing. These mineral fillers not only significantly reduce the raw material costs of plastic products but also provide skeletal support, improving the material’s rigidity, heat resistance, dimensional stability, and surface gloss. Through high-precision grinding processes, our equipment can process natural ores into functional powders with good compatibility with polymer materials, widely used in plastic films, pipes, injection molded parts, and rubber products, helping companies reduce production costs while giving products superior physical and mechanical properties.

Process & Solutions
Addressing the stringent requirements of the plastics and rubber industry regarding filler particle size distribution, oil absorption value, and dispersibility, our equipment can complete the entire process of crushing, grinding, grading, powder collection, and packaging, ensuring that the powder achieves optimal filling and reinforcing effects within the plastic matrix.
Stage 1：Crushing
Large ore raw materials (such as calcite and talc) are first coarsely crushed by a jaw crusher, then finely crushed by an impact crusher. The particle size is strictly controlled within the range of 15mm-30mm to meet the feeding standards of the grinding mill, while ensuring uniform particle size and reducing over-grinding.
Stage 2：Grinding
The crushed material is fed into the raw material hopper by an elevator, and then uniformly and quantitatively fed into the grinding chamber of the mill by a vibrating feeder.
● Ultrafine Powder Processing: For 1250-2500 mesh ultrafine powders required for high-end plastic masterbatches, films, and high-grade cable materials, we primarily recommend the CLUM series ultrafine vertical mill and the HGM series ultrafine powder mill. The CLUM vertical mill uses a bed grinding principle, producing spherical particles with good flowability, significantly reducing the oil absorption value of filler plastics. The HGM micro-powder mill uses multi-layer grinding rings, suitable for processing materials with a Mohs hardness of 7 or lower, achieving a fineness of less than 5μm. Furthermore, the absence of metal-to-metal contact within the equipment ensures high powder purity.
● Conventional Fine Powder Processing: For 325-800 mesh fillers required for PVC pipes, profiles, injection molded parts, and recycled plastic granulation, we recommend the CLRM series high-pressure suspension roller mill (Raymond mill). This equipment is technologically mature, operates stably, and produces a concentrated particle size distribution, making it a classic choice with excellent cost-effectiveness, particularly suitable for large-scale industrial production.
●Fine Grading Processing: For special engineering plastic fillers with extremely narrow particle size distribution requirements, a CLCM series vortex mill can be selected for fine processing. High-speed shearing force achieves ultra-fine grinding and grading of materials, ensuring uniform powder dispersion in the resin.
Stage 3：Classification
The ground material enters a high-efficiency turbine classifier with the airflow. By adjusting the rotation speed of the classifying wheel, the required particle size range (e.g., D97≤10μm) can be precisely cut. Qualified fine powder enters the collection system with the airflow, while coarse particles automatically fall back into the grinding chamber for further grinding, forming a closed-loop circulation. This ensures a concentrated particle size distribution in the finished product, free of coarse impurities, and avoids the formation of crystal points during plastic processing.
Stage 4：Powder Collection
The micro-powder meeting the fineness requirements enters a pulse dust collector for gas-solid separation with the airflow. The entire system operates under negative pressure and is equipped with a long-bag low-pressure pulse dust collector. Dust emission concentrations are far below national standards, with a collection efficiency of up to 99.9%. The collected finished powder is discharged through a discharge valve into the finished product silo.
Stage 5：Packaging
The finished powder is packaged into 25kg bags or ton bags using an automatic packaging machine. The entire process is carried out in a closed system to ensure no dust contamination and to guarantee the cleanliness of the finished product during transportation and storage, facilitating direct use by downstream plastic plants.
