Suitable for the production of LVT plastic flooring and wall panel products with a thickness of 4.5mm-5.5mm. 1. Use automatic weighing system to ensure accurate measurement of ingredients each time. 2. Use an internal mixer to mold the rubber material, which has good dispersion effect, high work efficiency, and no dust in the environment. 3. A four (two) roller calender is used to produce the sheet, with high precision. 4. The roller is made of peripheral drilled rollers and surface sprayed with tungsten carbide, which is strong and wear-resistant and has small temperature error on the roller surface. 5. Each roller is independently driven by a motor, the transmission is smooth, and the roller speed ratio is arbitrarily adjustable to meet the requirements of different processes. 6. The roller support bearing adopts high-precision calender bearing, which has high centering accuracy and the product thickness error can be within ±0.01mm.
