Frequently a screw press performs better if material is shredded before being admitted into the press. For that purpose Vincent Corporation offers a line of shredders. These are sized to bolt directly onto the inlet of Vincent screw presses.
The Vincent shredder is a horizontal machine with a 180 degree discharge area on the underside. It is ideally suited to bulky materials, such as citrus peel, whole fruit, and produce waste.
The blades rotate about a horizontal shaft. They are fixed; they do not swivel. The blades are made of hardened 410 stainless, and they are keyed to the rotor. The blades are sharpened at a 45 degree angle when slicing, as opposed to mashing, is required.
The material being shredded is forced through the discharge of the machine. The material can be thrown through a screen, a comb, or a free opening, depending on the machine configuration. The VS models have a screen mounted in the discharge, while the VCS models have a comb (or grille) in the discharge. A tooth from the comb fits between each pair of rotor blades.
The VCS models are very susceptible to serious damage if rigid tramp material, such as tools or rocks, fall into shredder. Also they are susceptible to jamming on start-up if material is left in the machine. For this reason they are commonly used without the comb in service.
A variety of screen sizes are available for those models which use screens. Typically these are in the range of 3/4" to 2", generally in the form of square-round holes. Screens are made of either 304 stainless or carbon steel.
Large shredders are typically fed with a screw conveyor. Since the shredder throws material upward as well as downward, it is important to have a cover over the screw conveyor trough at the shredder.
8" and 12" shredders are frequently used for laboratory and pilot operations. Where these machines are batch fed, a dogleg inlet chute should be used to prevent throw-back material from making a mess or causing injury.
Shredder housings can be either split or hinged, so as to allow ease of clearing jams, changing rotors, or replacing screens. In operation the upper part of the housing fits folded around the inlet chute, or it is bolted to the bottom flange of an inlet chute.
Vincent shredders are powered by premium efficiency electric motors. These are direct coupled to the rotor shaft. Some models, with two bearings, use Dodge Para-Flex couplings. Other models, with one outboard bearing, use rigid couplings.
Vincent shredders use 304 stainless for parts that are in contact with the material being shredded. Base frames are made of mild steel.
