In the injection molding workshop of an electronics factory in Dongguan, a Sinburller® low-speed pellet machine is silently crushing sprue material into uniform pellets, while in the adjacent workshop, a high-speed clap-type crusher is tearing thick-walled plastic buckets into pieces within 3 seconds. These completely different operation scenarios reflect the technical logic behind the selection of plastic crushers - there is no perfect equipment, only solutions that match the requirements.
Four types of differentiated crushing equipment
Low Speed Granulator: It adopts a double-roller shearing design, with the rotational speed controlled at 80-120 revolutions per minute. In the tests in the precision mold factory, it successfully crushed the ABS sprue material into uniform particles of 0.8-3mm, and the dust generation was reduced by 72% compared with traditional equipment. A medical equipment manufacturer has reported: "It enables our transparent PC material to maintain a light transmittance of 98% even after recycling."
Medium Speed Granulator: By optimizing the gear transmission ratio, it achieves a stable output of 300-500 revolutions per minute. Application cases in automotive interior parts factories show that it can efficiently handle PP bumper waste, with a 40% reduction in unit energy consumption compared to high-speed models, and the production capacity reaches 1.2 tons per hour. The workshop director did the math and said, "With the same electricity bill, we can now handle 30% more scraps."
Silent Claw Type Crusher: Equipped with multi-layer sound insulation covers and hydraulic buffer devices, in the actual measurement of the office equipment production line, the operating noise has been reduced from 85 decibels to 62 decibels, which is equivalent to changing the crushing operation from the "sound of an electric drill" to "soft conversation". What surprised the HR department even more was that the employee complaint rate dropped by 90%.
Claw Type Crusher: It adopts high-strength alloy steel claws and a turbocharged design. In the test at the packaging materials factory, it can tear an HDPE barrel with a diameter of 1.2 meters into 50mm fragments in just 15 seconds, and the torque output is 25% higher than that of similar products. Old Zhang, a recycler, gave a thumbs-up and said, "This machine gnaws thick-walled plastic even harder than a pair of pliers."
The golden rule for selection is called "Three Questions Determine the outcome"
Choosing a crusher is like hiring a chef for a factory; you have to first figure out what dishes to cook. The technical director of Sinburller® summarized the selection logic with a life-like metaphor.
Question about materials: For soft films, choose the claw type machine; for hard plates, use the pellet machine; for transparent materials, the low-speed model is a must - a certain cosmetic packaging factory once used a high-speed machine to crush PC pipes, resulting in the recycled materials turning yellow and being scrapped, with a loss of over 200,000 yuan.
When it comes to space: The silent model is suitable for the workshop next to the office. For open factories, the basic model can be chosen. The experience of a certain 3C parts factory in Shenzhen is that for every 10 decibels increase in noise, the efficiency of employees drops by 5%.
Asking about the budget: Medium-speed models are the Kings of cost performance, but in the long run, the reduction in dust from low-speed models can save tens of thousands of yuan in annual maintenance costs for dust removal equipment.
The "intelligent brain" of the crusher
The particle uniformity control system equipped on the low-speed machine can adjust the roller distance in real time through the laser sensor to ensure that the size deviation of each particle does not exceed ±0.2mm.
The intelligent torque feedback device of the claw machine will automatically reverse for 0.5 seconds when encountering metal impurities to prevent damage to the tool claws. Data from a certain power plant shows that this function extends the tool life by three times.
The sound insulation cover of the silent machine is made of aviation-grade sound-absorbing cotton. The internal structure has been optimized through 2,000 acoustic simulations, and even the sharp sound when breaking glass can be reduced by 80%.
"Treating the root cause of a headache" has evolved into "precise matching"
"Before, buying a crusher was like drawing lots. Now that we have a selection guide, even the finance department praises us for being good at accounting." The person in charge of the supply chain of Midea Group presented their equipment list: the injection molding workshop is equipped with a low-speed pellet machine, the blow molding workshop uses a medium-speed model, the packaging workshop is installed with a silent type, and the waste station is equipped with a claw type machine. The total price of the four machines has not increased, but the quality of recycled materials has improved, the dust treatment fee has decreased, and there are fewer complaints from employees.
Making Fragmentation the starting point of a circular economy
The Sinburller® crusher is designed with environmental protection ingenuity. All models are equipped with a magnetic separation device as standard, which can separate 99.8% of metal impurities, ensuring that the purity of recycled materials meets food-grade standards.
The sealed design of the low-speed machine keeps the dust emission concentration below 10mg/m³, which is far lower than the national standard of 30mg/m³.
The modular tool set of the claw-type machine reduces the replacement cost by 60%.
A certain recycling enterprise has calculated that the money saved on cutting tools over three years is enough to buy a new machine.
The general manager of Sinburller® outlined the vision at the annual technology release conference: "We are developing an AI material identification system. In the future, the crushing machine will automatically adjust parameters, making the selection process a thing of the past."
From addressing dust pollution to promoting plastic recycling, Sinburller® is demonstrating through technological innovation that in the field of environmental protection equipment, precisely matching demands is more important than pursuing the ultimate parameters.
