Equipment introduction: Four-shaft shredder is developed based on market demand products. It adopts automatic control of microcomputer (PC) to set automatic start-up, stop, reverse and overload reversing control functions. It is mainly used for shredding light and thin metal with certain strength and waste garbage to increase its packing density for transportation and re-use . Performance characteristics : 1. Large torque, high yield, no manic, resistant to wear, etc. 2. Can to sharply reduce chip processing of iron filings volume. 3. Chip, horizontal double roller crusher can make the chip drying, briquetting, smelting, and broken, in the early period of the chemical fire prevention materials handling and pneumatic conveying becomes easy. 4. To cut broken down strips of metal processing tool cutting, spiral, sheet of metal scrap. 5.This Scrap metal shredder is the idea machinery for Ferroalloy smelting, metal steel scrap, scrap iron, scrap metal and scrap recycling companies. 6. This scrap metal crusher machine can be equipped with conveying feeding device. Working principle and structure: Using of high-torque blades for physical cutting, tearing, sawing and other means in the closed silo to the initial shredding materials, and then Tongli original screening technology, screening out the size of the material to meet the requirements; does not meet will automatically back to the material Continue processing. Application field: Metal shredder is widely employed to crush paint bucket, discarded appliances shell (plastic shell, metal shell), large pipes, pipe fittings, forklift pallets, tires, drums, aluminum and copper, as well as being used to crush iron sheet, scrap circuit board,and so on. Applicable material range: Paper making derived waste, cartons, paper rolls, wood; · Plastic barrels, plastic electrical shell; Metal cans, thin-walled metal buckets, metal shell of appliances; � circuit boards, mixed light industrial waste; Carpets, woven bags, household garbage sieve; Light construction waste, medical waste; Biomass and alternative fuel preparation industries; Particularly suitable for crushing the particle size of the higher applications; Broken material is smaller or medium-sized uniform size sheet.
