Calcium carbonate is a key industrial mineral extensively used in various applications such as plastics, paints, coatings, paper, and particularly in rubber as a reinforcing and cost-reducing filler. In Malaysia, the demand for fine, consistent calcium carbonate powder of about 200 mesh has escalated due to the thriving rubber manufacturing industry. The quality and characteristics of the calcium carbonate used significantly affect the performance of rubber products, including tensile strength, hardness, elongation at break, and abrasion resistance. Therefore, efficient and precise grinding is essential in ensuring product quality.
Shanghai Zenith Machinery Co., Ltd., a leading Chinese manufacturer of grinding equipment, has been a trusted supplier of industrial powder grinding equipment worldwide. The company provides advanced grinding solutions that meet global standards, with a special focus on ultra-fine powder production for industries such as rubber, coatings, and plastics.
In the rubber industry, calcium carbonate serves both as a reinforcing agent and an economical extender. The particle size distribution is a crucial determinant of filler properties. For rubber products, 200 mesh calcium carbonate is often preferred because it offers a desirable balance between surface activity and dispersion, ensuring homogeneous mixing with rubber compounds. This level of fineness optimizes the reinforcement effect without adversely affecting elasticity or flexibility.
When ground to 200 mesh, calcium carbonate enhances processability and dimensional stability while improving the final product’s aesthetic appearance and smoothness. Additionally, its inclusion allows rubber manufacturers to reduce the consumption of expensive raw materials like natural rubber or synthetic polymers, cutting production costs without diminishing quality.
The production of 200 mesh calcium carbonate demands careful selection of grinding equipment that ensures consistent particle size, high capacity, and low energy consumption. Traditional grinding technologies may not meet these stringent requirements, especially when fine powder uniformity and environmental compliance are critical. High humidity levels and feedstock variability in Malaysian conditions add another layer of complexity to the grinding process.
In response to these industrial demands, Shanghai Zenith Machinery Co., Ltd. offers specialized mills designed for stable, efficient, and precise grinding of calcium carbonate. Among these, the MTW Trapezium Grinding Mill and the XZM Ultrafine Grinding Mill have proven to be ideal for producing fine powders suitable for rubber filler grades.
The MTW Trapezium Grinding Mill is engineered with innovative technology that ensures high efficiency and stability. It is particularly suited for processing non-metallic minerals like limestone, calcite, and dolomite into fine powders within the 1.6–0.045 mm range. For rubber filler applications, it can consistently produce 200 mesh calcium carbonate with a uniform particle size and excellent dispersion characteristics.
Its unique features include a bevel gear transmission system, arc-shaped air ducts that minimize energy loss, and a high-efficiency fan for uniform airflow. The mill’s compact structure and durable materials significantly extend its service life while ensuring minimal maintenance downtime.
| Model | Max. Feed Size (mm) | Final size (mm) | Capacity (t/h) | Main motor (kW) | Fan motor (kW) |
|---|---|---|---|---|---|
| MTW138Z | <35 | 1.6-0.045 | 6-17 | 90 | 110 |
| MTW175G | <40 | 1.6-0.045 | 9.5-25 | 160 | 200 |
For large-scale Malaysian rubber filler plants, the MTW175G model provides sufficient throughput with outstanding precision and low power consumption. It is designed to operate under tropical environmental conditions, ensuring reliable output even in humid climates.
For ultra-fine powder production needs beyond 200 mesh or when higher brightness and purity are desired, the XZM Ultrafine Grinding Mill is an ideal choice. It can produce powders as fine as 2500 mesh, ensuring flexibility for various downstream applications within the rubber and plastics industries. The XZM series features a high-speed turbine classifier for accurate particle size control and a multi-head design for improved production efficiency.
The XZM Ultrafine Grinding Mill is compact and energy-efficient, with intelligent control functions for pressure, vibration, and feed rate adjustment. These features ensure consistent quality output while reducing operational costs—an important advantage for manufacturers facing competitive pressures in Malaysia and across Southeast Asia.
| Model | Working diameter (mm) | Max feed size (mm) | Final size (mesh) | Output (kg/h) | Main motor power (kW) |
|---|---|---|---|---|---|
| XZM221 | Φ800 | ≤20 | 325-2500 | 500-4500 | 75 |
| XZM268 | Φ1680 | ≤20 | 325-2500 | 5000-25000 | 315 |
The XZM268 model is particularly suitable for Malaysian rubber filler producers targeting high-grade or specialized rubber compounds. Its superior classification performance ensures that the 200 mesh product retains uniform texture and excellent whiteness, meeting the strict requirements of tire and industrial rubber production.
Malaysia possesses abundant limestone reserves, particularly in Perak and Pahang, offering a sustainable raw material base for calcium carbonate production. By integrating Zenith’s MTW or XZM mills, local processors have achieved remarkable improvements in productivity and output quality. Typical 200 mesh calcium carbonate produced using Zenith’s solutions meets industry standards for whiteness and oil absorption, both critical for rubber products such as hoses, seals, and conveyor belts.
The combination of robust mechanical performance and smart design enables Zenith grinding mills to perform efficiently under high-moisture conditions often found in tropical Malaysia. Additionally, energy-saving technology reduces total power consumption by 20–30%, contributing to lower overall production costs.
As Malaysia’s rubber industry continues to expand, the need for high-quality, cost-effective calcium carbonate fillers will grow correspondingly. Shanghai Zenith Machinery Co., Ltd. offers exceptional grinding technology through products like the MTW Trapezium Grinding Mill and XZM Ultrafine Grinding Mill, providing clients in Malaysia with reliable, efficient, and sustainable solutions. With their advanced design, superior grinding precision, and customizable output, these mills stand as the optimal choice for producing 200 mesh calcium carbonate tailored for modern rubber filler applications.
