The Vertical Grinder was invented in 1966 by Roy Eidal of Eidal Heavy Industries. This industrial conglomerate was put together under the leadership of the visionary Roy Eidal in 1943. The conglomerate was divested and sold to various other companies after his death.
The Burda Family, originators of the Saturn and SSI products added this line to their company in 1983
The design was originally planned to shred scrap metal to make steel frag for the steel industry
The design was made by the Dravo Group of Pittsburg under the direction of the Eidal Group.
The design originally had a cone shaped tub with a center rotor with a top knocker and grinder rings on a straight rotor assembly
The design has many combinations today, cone tub, straight tub, inverted cone, or a combination of all of these tubs
The design of the rotor also has many combinations today, top knocker, small to large rotor or straight rotor or large to small rotor
The design of the rotor also uses hammers, rings, chain and other mechanical grinding devices like rasper and granulator blades
The machine is very versatile and is used worldwide by General Motors and Merck.
The Vertical china shredder comes in many sizes. V50, V100, V150,V200,V400, V750, V1000 and V2000 units
These model designations do not only relate to the power of the machines in HP, but also to their sizes.
One recent adaptation for the Eidal Grinder is the use of the equipment for cleaning tire wire, after it has been liberated from the rubber by the Rasper. The violence of the shredder makes the fine steel particles break off any remaining rubber. The end product can then be screened to separate it from the rubber after it exits the machine.
The V200 and V400 and V1000 series are great shredders for the scrap metal operation and municipal solid mast operation.
There are hundreds of these machines in operation worldwide with great success in Japan for Municipal Solid Waste processing to fuel.
The machines are compact, in comparison to most shredding lines and are built tough for the job.
