The Rotochopper EC-156 Horizontal Grinder (Electric) is excellent for C&D, wood waste, pallets, edgings, process slabs, bark, trees and pole peelings. The Rotochopper Model EC-256 horizontal grinder is powered by a 300 hp, 3-phase electric motor. The unit includes 26″ diameter x 56″ wide rotor with a 56″ wide x 18″ feed opening and a 56″ wide x 18′ long heavy-duty steel belted feed conveyor. The grinder is PLC operated, with a 22′ discharge conveyor with magnetic head pulley, fixed hammers, 2″ screen and controls. It is in good working condition and has an output of 250 yards per hour.

Rotochopper grinders are popular in the forestry slash industry because of their precision grinding capability and maneuverability. These diesel powered horizontal grinders are known for their superior particle size control and efficiency. Rotochopper grinders are used worldwide in manufacturing raw products such as construction and demolition material, mulch and boiler fuel and are also used in processing municipal yard waste into usable mulch.

One growing industry that requires use of a grinder is asphalt shingle recycling. Recycling the asphalt-cement in shingles benefits asphalt producers by reducing AC costs and improving the quality of their product, as well as reduces the nation’s dependency on foreign sources of oil and clears up valuable landfill space for products that can’t be recycled and reused. Asphalt shingles can be recycled into a variety of products, including hot mix asphalt, cold patch, dust control on rural roads, temporary roads and driveways, aggregate road base, new shingles and fuel. With the rising cost of petroleum, the economic benefit of using recycled asphalt shingles (RAS) is also increasing. Using RAS reduces overall costs on projects in several industries, such as the overall cost of paving a road or roofing a house.

Hot-mix asphalt (HMA) is currently the largest market for RAS. Using recycled asphalt reduces the demand for virgin asphalt cement and aggregate, which economically benefits HMA producers. Cutbacks from shingle factories can be ground and added during the HMA process, and the ceramics in shingles serves as a source of aggregate in the mix, reducing the demand for mined aggregate. The addition of RAS has been proven to improve rutting and cracking resistance in asphalt pavement because the added mineral fillers and organic fibers help reinforce the matrix.

Grinders use abrasion and compression to pulverize materials to a reduced size, using a series of wheels, drums and plates to process the material. Material is passed through a wide feed hopper, falling into the grinding chamber. Often, grinders use a hammermill in the grinding chamber to process the shingles. In this case, the grinding chamber contains a rotating hammer rotor with swinging hammers that crush the shingles and drive them through a screen, thus using impact grinding to reduce the material into smaller scraps.
