September 2020 / 39 than a gentler material. The appli- cation's feedrate also dictates the screen's lifespan, and the supplier can provide a maintenance plan depending on each client's applica- tion and material.

Midwestern Industries Massillon, OH 877-474-9464 www.midwesternind.com more about the screener's perfor- mance. If a customer is unable to attend a test, the supplier can pro- vide a live video call or recorded testing video. The customer also receives several testing result sheets, including a sieve analysis, rate sheet, feedrate percentages, and more process calculations. The supplier also has an archived library of 'blind/confi dential' test result video samples to streamline customer education. After reviewing the testing pro- cess and results, the green-focused client purchased the MEV screener for its EOL tire recycling operation. The new equipment provides the company with an effi cient screen- ing solution that preserves the recovered carbon black material's properties. The screener requires minimal maintenance outside of new screens. The screen replace- ment frequency depends on the material. An abrasive material will wear out the screens more quickly frequency screener. The 5-by-10- foot rectangular screener features fi ve screening decks that are able to separate the material into one to fi ve diff erent particle sizes. The MEV provides high volume fi ne mesh screening, which is required for many applications in the quarry and rock, sand and gravel, pet food, clay, brick, and lime industries, among others. The MEV uses an elliptical motion to move material across its screening surface, and the screener retains material at the feed end for a period of time before the material is gently discharged off the screen- ing deck and onto the next produc- tion stage. Crossbars support the end-tensioned screens to create a fl at screening surface, which maxi- mizes the screening area. The material testing on the MEV screener was completed within a few hours with the client in atten- dance on-site, which provided an opportunity for the client to learn A tire recycler visited the testing facility to nd a new screener to separate rubber from carbon black and other chemicals. www.monitortech.com monitor@monitortech.com Tel.: 1-630-365-9403 Toll-Free: 800-601-5949 Quality l Dependability l Integrity For over 60 years!
