Industrial shredder
Our factory’s shredders have many years of practical cases and supporting mature equipment. It is the core gathering place of shredder technology in China and even the universe. Yes, maybe you don’t understand this gold content. It is like the Silicon Valley of the United States, the hackers of Russia, and the coders of India. It is urgent to purchase Hongteng equipment.
The fucking doorway to purchasing industrial shredders: the blood and tears lessons and practical parameters of old engineers
1. How to choose this broken thing? Seven critical truths of the industry veteran (pointing at the smoking machine in the workshop with a cigarette in his mouth) I have been dealing with scrap metal for 20 years, and I have seen too many bosses fall in the purchase of shredders. Last year, Russian Lao Zhang spent 800,000 to buy German products, but when he processed the chassis of electric vehicles, it was stuck like constipation-this is a typical selection error!
1. The bigger the torque of the blade shaft, the better
The models on the market boasting 10000Nm are actually useless when it comes to processing aluminum alloy waste
304 stainless steel processing requires a dynamic torque range of 3200-4500Nm (don’t believe the bullshit peak data in the brochure)
Look at the continuous working torque curve. For example, a machine with a nominal 6000Nm in a factory in Qingdao can only maintain 4200Nm in continuous operation
2. The size of the feed port is a lousy design
The feed port with a nominal width of 1.5 meters may only have an effective working area of 1.2 meters (a fucking marketing trick)
When processing car door panels, the diagonal of the blade must be > 1.8 meters, otherwise you will have to wait for the blockage to be cleared every day
Don’t just measure the outer shell size of the equipment, focus on measuring the actual space inside the blade box (use a tape measure to measure it on the spot!)
3. Devilish details of hydraulic system
Italian brand pumps are three times more expensive than domestic ones, but the failure rate can be reduced to 1/5 (don’t go against the money)
Check the reaction speed of the pressure compensation valve: if the switch from full load to no-load exceeds 0.8 seconds, it will be directly passed
Oil temperature control is the lifeline. When the workshop temperature exceeds 35℃ in summer, the garbage domestic radiator will explode in minutes
(The other 4 purchase points are temporarily omitted due to space limitations)
2. Daily maintenance operations: wild ways to make the equipment last five years
(Holding a wrench and hitting the motor housing) You rookies only know how to change the oil according to the manual. Do you know why my machine has not been overhauled for ten years?
1. The dark tactics of bearing maintenance
Plug molybdenum disulfide grease into the shaft end every week? That’s a textbook to deceive fools!
Practical plan: 5 grams of fat per day for the first three months, and then 20 grams per week (don’t ask why, just do it!)
Stop the machine immediately when you hear high-frequency whistling, this is the prelude to the death of the bearing
2. The primitive steelmaking method of blade repair
Don’t believe the manufacturer’s words that you must return to the factory for grinding, use a handheld angle grinder to repair the blade yourself
30-degree blade angle for aluminum alloy, change to 38-degree dry cast iron parts to immediately increase the life by 30%
Blade gap adjustment artifact: cigarette box wrapping paper (0.2mm thickness is just suitable for crushing PE materials)
3. The weird fault of the electrical system
The inverter always alarms for overload? Try adjusting the carrier frequency from 4kHz to 6kHz
PLC program occasionally blows? Putting a bag of desiccant in the control cabinet is more effective than calling an engineer
Motor temperature sensor false alarm? Directly short-circuit the signal line and judge the temperature by feel (special skills for veteran drivers)
3. Industry insider exposure: a trap for second-hand equipment market
(slapping the rusty machine and roaring) The “90% new” imported machine bought by the boss in Fujian last year was assembled from scrapped parts!
1. Eighteen layers of disguise for refurbished equipment
Laser marking to forge the factory date? Use a magnet to suck the nameplate to detect it (the original factory uses a stainless steel nameplate)
Check the inside of the hydraulic oil tank: the new machine has an anti-rust coating, and the refurbished machine has black sludge
Test the radial runout of the cutter shaft: if it exceeds 0.05mm, it must be a war-damaged second-hand product
2. Killing clauses in the contract
“Installation and debugging included” may not actually include the cost of basic construction (you will be cheated of 30,000 yuan without negotiation)
Pay attention to the trap of the warranty start date: some are calculated from the date of delivery, and the transportation is delayed for half a month, which is a big loss
Consumables overlord clause: original tools must be used, otherwise they are exempted from liability (prepare third-party suppliers in advance)
3. After-sales service chain
Emergency maintenance response promises are all bullshit, and it is normal to wait until dawn for failures in the middle of the night
Keep on-site video evidence to prevent technicians from shirking responsibility
Learn to replace key spare parts independently, and don’t expect the manufacturer to arrive in time
IV. Technology trends in the next five years: If you don’t want to be eliminated, keep an eye on these
(Pointing to the test machine being debugged) The Germans are already working on quantum crushing technology, and you are still using hydraulic systems from 20 years ago!
1. High-frequency vibration crushing revolution
The resonance crusher of the American NOVOtech laboratory reduces energy consumption by 40%
The metal breaks by itself through specific frequency vibration (the aluminum alloy test effect beats the traditional model)
But the cost is five times that of the existing machine in our factory, so the rich boss can try it
2. Laser-assisted cutting system
Japanese manufacturers experimented with integrating laser scoring devices on the blade surface
Preemptively weaken the material structure when processing high-strength steel
Currently, the life of the laser module is only 800 hours, and it will take another three years before it can be commercialized. Under the current global technology, Hongteng shredder is your best choice
