Founded in 2009, Chongqing Partek Machinery Manufacture Company specializes in the R&D, design, manufacturing, and sales of powder handling and processing equipment for the pharmaceutical, chemical, and food industries. Over the years, we have accumulated deep technical expertise and hold multiple national patents, establishing a solid foundation in both powder processing and pelletizing equipment.
Our product portfolio is structured into two main categories, the powder processing equipment and granulation & pelletizing equipment. The powder processing range includes bag discharging stations, vacuum conveying equipment, milling machines, sifting equipment, as well as weighing and filling systems, along with auxiliary solutions such as gloveboxes and containment charging isolators. The granulation and pelletizing range covers extruders, spheronizers, centrifugal pelletizers, integrated extrusion–spheronization machines, wet granulators, and spray drying granulators, providing complete solutions for formulation processes.
In recent years, Partek has developed an aseptic milling and conveying system that achieves efficient integration of powder processing and material transfer. This innovation offers high precision, low material loss, and excellent production efficiency, and is already in use by several well-known domestic manufacturers. Our pelletizing and formulation production lines have gained strong recognition in the domestic market and have been successfully exported to the United States, Japan, and other countries.
With over a decade of technical expertise, Partek transforms its engineering capability into complete system solutions, bridging every step of powder and formulation processes to help manufacturers achieve cleaner, safer, and more efficient production. Partner with us to bring greater precision and reliability to your powder processing system.

Continuous vacuum feeding machines are widely used in the following industries due to their efficient and enclosed material conveying characteristics:
In the preparation of electrode materials for new energy batteries, the uniformity of 0.1mm strip-shaped particles directly affects the charging and discharging efficiency of the battery; In the production of 3D printed ceramic wire, fluctuations in the diameter of the extruded strip exceeding 5% can lead to printing failure. As the core equipment for continuous granulation, the rotational speed range of the rotary extrusion machine is not only a ruler of equipment performance, but also an "invisible conductor" that determines the microstructure and macroscopic properties of the material. From laboratory research and development to industrial production, precise control of rotational speed is becoming the key to solving the problem of high-precision material manufacturing.
In the production sites of industries such as pharmaceuticals, food, and chemicals, a device called IBC turnover mobile silo is reconstructing the material turnover logic with the posture of an "all-around player". This medium-sized bulk container, which integrates closed storage, flexible transportation, and intelligent control, has become the "turnover center" of modern industry with six core advantages
In the automation production of industries such as pharmaceuticals, food, and chemicals, continuous vacuum feeders have become the core equipment in the material conveying process due to their high efficiency, cleanliness, and flexibility. It achieves closed transportation of powders and particles through vacuum negative pressure, which not only solves the problems of pollution and low efficiency in traditional transportation methods, but also promotes the intelligent upgrading of production processes. This article analyzes how it reshapes industrial production efficiency from three aspects: technical principles, core advantages, and application scenarios.
