Chipper RM-5 (and its modifications) is designed for grinding technology of waste wood chips (slab, rod, tops and trunks of wood with a diameter of 150 mm), as well as waste lumber, veneer, slab production and flaws veneer. Philadelphia Condos may not feel the same. Mechanisms of cutting and filing are combined in one package, provides a quick and easy change of cutting blades (up to 40 regrinding) and the anvil (up to 5 regrinding), the cutting mechanism has a built- sieve, which improves the grain size obtained by chipping when installing chippers RM-5 is not necessary to erect a special foundation. The resulting technology can use wood chips as fuel in mobile thermal power stations, gas generators, boilers, working at the waste wood, in the lines for the production of fuel briquettes, pellets (pellets) for the production of chipboard, wood fiber, cement particle board, wood-polymer materials, pulp, building blocks (as filler) used for smoking foods, livestock are used as litter in crop production as fertilizer. Fashion direction of landscape design is design tinted chips parks, gardens, playgrounds, summer cottages. On order chipper RM-5 can be equipped with the feed conveyor, and for removal of chips – conveyor belt or blowers, a device for sharpening knives. In chippers RM-5R and 55R RM-installed speed control for flow chip thickness variation from 5 to 1 mm. Chips after reduction feed rate (wet alder) gauge sieve gives the fraction of gost 15815-83, hole d = 50 mm and d = 25 mm chips after reducing the feed rate (dry oak), wood chips, after reducing the feed rate (wet alder) gauge sieve gives the fraction of gost 15815-83, hole d = 50 mm chips after reducing the feed rate (dry oak)
