If you are running a plastic recycling factory in Nigeria, you probably know this headache too well. You crush pure water sachets (Pure Water Nylons) into flakes. They are light, bulky, and full of static electricity. You dump them into the hopper of your plastic granulating machine, and then the trouble starts. 

The recycling business in places like Lagos (Oshodi, Alaba), Kano, or Onitsha is highly profitable, but only if your machines keep running without stopping. For many factory owners, the feeding throat of the extruder is where the money stops flowing, and where precious diesel gets wasted in your generator. 

To solve the issue, we must first understand why local LDPE film flakes behave this way. Unlike heavy rigid plastics like HDPE gallons or PP crates, crushed pure water bags have an extremely low bulk density. They are mostly air and very fluffy. 

Furthermore, during the crushing and drying process, the friction between these thin nylons generates a massive amount of static electricity. In the hot and humid climate of Nigeria, this static causes the flakes to behave like a bunch of magnets, sticking to each other and to the metal walls of your machine’s funnel. 

This behavior leads to the notorious “Bridging” Problem. The light nylon flakes lock together inside the funnel, creating a hard, arched bridge with an empty cave underneath. The material stops flowing into the screw completely, causing your extruder to run empty. When the machine runs dry, you will hear a terrible screeching noise in the factory, the temperature inside the barrel spikes, and the remaining plastic burns inside, creating a terrible smell and ruin your screw layout. 

The direct result of bridging is Uneven Feeding. After a few minutes of running empty, the “bridge” suddenly breaks, and a massive, compacted clump of nylon drops down into the barrel all at once. The next minute, the feeding stops again. This constant fluctuation makes the pressure inside your barrel completely unstable. Your extruded plastic strands become thick and thin like a snake, leading to frequent strand breaking at the water tank. Every time a strand breaks, your workers must run and re-pull the hot plastic to the pelletizer, stopping your production line and making your expensive Mikano or Lister generator burn diesel for zero output. 

Walk into any local recycling hub in Nigeria, and you will often see a costly mistake in action. Operators stand on a high platform, holding a long wooden stick, a bamboo pole, or even a metal pipe, constantly poking, bashing, and fighting the nylon flakes down into the hopper manually. 

While manual labor might seem cheap in Nigeria, this method carries massive, hidden financial risks that can shut down your entire business. Let’s be honest—it is a disaster waiting to happen. It only takes one second of distraction for the operator to push the stick too deep. If that piece of wood gets caught in the spinning screw, you will hear a loud “Kalo-Kalo” sound, and the machine will jam instantly. 

Best-case scenario, you shear a safety pin or trip the breaker. Worst-case scenario, you destroy your heavy-duty gearbox, twist your extruder screw, and crack the barrel. Replacing a heavy-duty screw and barrel in Nigeria means importing spare parts from overseas, facing high shipping costs, and dealing with custom clearing delays at Apapa port. Your factory could be shut down for three to four weeks, costing you millions of Naira in lost production, wasted worker wages, and ruined customer contracts. Your expensive machinery becomes “condemned” all because of a wooden stick. 

To scale up your recycling yard and secure your peace of mind, you need to eliminate human error and automate the process. The standard industry solution is installing a Force Feeder (also known as a Crammer Feeder) directly onto your granulator. 

A Force Feeder uses a heavy-duty, high-torque vertical screw to actively compress, pack, and drive the fluffy, static-heavy pure water nylons straight down into the main extruder screw. It completely replaces the dangerous manual stick method.

First, a crammer feeder 100% eliminates bridging. Because the feeder screw is constantly rotating inside the hopper, it physically breaks any static attraction or interlocking between the films. The nylons have no chance to form an empty cave, ensuring a steady, continuous flow of material twenty-four hours a day. 

Second, it ensures consistent output and stops strand breaking. Because the main screw receives the exact same volume of plastic every second, the internal pressure stays perfectly stable. Your plastic strands come out with a uniform thickness, running smoothly through the cooling tank into the pellet cutter without snapping. No more messy waste on the floor. 

Third, it boosts your production capacity by 30% to 50%. When your machine never runs empty and your strands never break, your daily tonnage skyrockets. You can process more tons of pure water bags per shift, maximizing your profit margins while using the exact same amount of diesel power. In a market with high fuel costs, maximizing your output per hour is the only way to survive and make huge profits. 

Finally, it guarantees factory safety. It keeps your workers’ hands far away from dangerous moving parts, reducing workplace accidents, keeping the factory inspector happy, and protecting your expensive machinery from foreign objects. 

Not all crammer feeders are built the same. When buying a plastic granulator with a force feeder for the African market, you must check three essential technical specifications to ensure the machine survives heavy daily shifts and local working conditions. 

First, look for Inverter Control (Variable Frequency Drive / VFD) on the feeder motor. The feeding speed must be adjustable. This allows your operators to fine-tune the force feeder’s speed to match the main extruder’s melting speed perfectly, preventing over-feeding, motor overloading, or material backup. 

Second, choose a High-Torque Motor with a Heavy-Duty Gearbox. Because pure water nylon flakes can sometimes wrap around the feeder shaft and create high resistance, a weak motor will burn out within a few weeks. A robust, high-torque motor ensures the feeder never jams, even when processing dense, slightly wet, or poorly dried film scrap collected during the rainy season. 

Third, insist on a Wear-Resistant, Nitrided Feeder Screw. Crushed pure water bags collected from the streets of Lagos or dump sites often contain a lot of sand, dust, or small stones. A standard steel screw will wear down and become smooth quickly under these abrasive conditions. A nitrided or bimetallic screw ensures long-lasting performance without losing its pushing power over time, saving you from frequent maintenance costs. 

If you want to produce premium, uniform LDPE granules that fetch top market prices from local plastic product manufacturers and injection molders in Nigeria, you must solve your feeding bottleneck. Stop relying on dangerous manual sticks that threaten to damage your expensive equipment.
