1. Introduction: Today, the market offers a wide variety of used woven bags for recycling, including ton‑bags, fertilizer sacks, cement bags, and industrial packaging, among others. Profits remain quite substantial. First, it’s important to understand what material these woven bags are made of: polypropylene plastic, abbreviated as PP in English. Next, after thoroughly assessing market conditions—ideally sourcing supplies from nearby areas—determine approximately how much material you can process each month or decide on the scale of your operation. Of course, this should also be aligned with your available start-up capital. For small to medium‑sized facilities, the 125‑ton model is generally a suitable choice, offering moderate energy consumption. If production volumes are somewhat higher and you’re planning a larger‑scale operation, consider models such as the 150‑ton or 180‑ton units.

2. Waste woven‑bag recycling pelletizing machine; features of the woven‑bag pelletizing production line: It supports both dry and wet processing—after cleaning, regardless of the moisture content, the material can be fed directly into the system.

It employs an electric heating control system equipped with fault‑indication alarms, high‑voltage protection, and leakage‑prevention alerts, while also featuring heat‑insulation and water‑resistance functions to ensure both reliable operation and user safety. The components are fabricated from carbon structural steel through processes such as quenching and tempering, forming, precision grinding, and carburizing, resulting in a service life exceeding that of standard screws by more than one order of magnitude. A hardened‑gearbox designed for the plastics industry is utilized to withstand substantial axial loads, radial forces, and overturning moments, thereby ensuring optimal performance. Optional equipment is manufactured in strict accordance with production specifications, guaranteeing uniform material blending and stable operational results. This approach effectively addresses common issues in extruders—such as inconsistent plasticization and unstable extrusion flow—caused by variations in batch‑to‑batch material volume, thickness, and dimensions.

Currently, the most common heating methods for plastic pelletizing machines on the market are coal‑based and electric heating. Compared with each other, coal‑based heating is more economical and cost‑effective, resulting in lower processing costs; in contrast, electric‑heated models tend to have a more attractive appearance, feature automatic temperature control, and may incur slightly higher operating expenses. As for machine specifications, there are single‑screw pelletizers and twin‑stage screw pelletizers. The latter generally offers higher production capacity and greater power, and it is particularly well suited for processing waste materials or compound resins, giving it an edge over single‑screw models. Buyers should also keep in mind that when purchasing equipment, they should never rely solely on the quoted price. As we all know, you get what you pay for. Be sure to request a detailed list of the machine’s standard configuration from the seller and compare options carefully. Many sellers, during verbal discussions, may tout “yes, yes” and “of course,” leading buyers to believe they’re getting a good deal at a low price—yet this isn’t always the case. Each manufacturer has its own specific configuration parameters, which directly correspond to the price. If the equipment features higher‑grade components, the price will naturally rise; conversely, if the specs are more basic, the price will be lower. Only by adhering to this principle can manufacturers truly act responsibly toward their customers. At Hebei Shuangda, we tailor our screw designs based on your specific type of plastic, offering solutions perfectly matched to your material requirements. We genuinely put our customers first, delivering high quality at competitive prices—so you can buy with confidence and use with peace of mind.

The plastic pelletizing machine’s automatic feeder (a forced‑feed device for plastic film, also known as a forced‑feeding unit) is mounted at the feed inlet. It offers easy operation, self‑supporting forced material compression, safe production, and reduced labor intensity. Compared with manual feeding, it can boost pellet output by 20%–30%. This auxiliary equipment is indispensable for recycling plastic pelletizing machines handling high‑ and low‑pressure films, woven bags, and other materials. It is compatible with various types of plastic pelletizers and features convenient installation and disassembly. Designed for water‑based processing, it features an electric, top‑loading die head that saves time and effort, eliminating worker fatigue—making it a replacement for traditional manual screen‑changing methods. Compatible with multiple pelletizer models, it enables rapid screen changes, high efficiency, and cost‑effectiveness, with a utilization rate exceeding 99% in Shandong.
