1. Main features:
(1) terials of Rolls :chiled Cast iron alloy (LTG-H), after quenching and precision processing, hardness HS 78.
(2) in bearing : Dual-listed rolling bearings, which reduces energy consumption by 40%.
(3) roll gap adjustment: electric automatic or manual
(4) Voltage: 220v, 380v, 415v Frequency control of motor speed or as per customer's request
(5) ducer: Airtight leaching oil type, ZSYE reducer (There are a variety of choice: hardened tooth, gear wheel reducer. the price is different), Almost no noise, safety and durable
2.Materials of Rolls:
The roller are made of chilled cast iron alloy (LTGH), whose surface is 78HS, after quenching and precision processing it is harder than other company (they are usually 72HS).
The working surface is well grined and machined.
Temperature uniformity in smooth surface,
High hardness, long working life.
3. Motor: We always use OMRON, SIMENS ect. brand electric parts or you can choice the ordinary brand. All the motor is high quality and effiency, save energy, low noise, and small vibration.
4. Roll gap adjustment: Roll nip adjustment is realized by hand or electricity which can obtain high accuracy and sensitivity.
The speed reducer is hardened tooth with class 6 precision, no noise and vibration, safety with higher transmission efficiency.(there are a variety of choice, the price is different), gear box(double out shaft transmission).
6. Frame: the base frame is a whole framework and cast iron, which is convenient for installation and easy to maintain.
7. Stock bender: it for direct rubber sheet and knife to cut as your need to assemble. Then improve the quality of mixing, and reduce the energy consumption.
8. Emergency brake device:
The machine is also equipped with an emergency brake device. When an emergent arises, just draw the safety pull rod or press the emergency button and the machine will stop immediately. It is safe and reliable.
The machine is equipped with an overload protection device to prevent the main components from being damaged.
9. Cooling system: (with rotating joint)
Universal rotary joints with inner spray pipes with hoses and headers. Piping is complete up to supply pipe terminal, which reduces energy consumption by 50% and high efficiency.
10. Auto-lubrication system for grease or oil and match bearing bush.
