Page 54 of 85 ROCK products • February 2018 • 51 EQUIPMENT & TECHNOLOGY SCREENING & SIZING McLanahan's MAX Series Vibrating Screens are designed to meet and exceed the demanding applications and specifications required of screen- ing equipment. MAX Series Vibrating Screens provide a custom engineered solution for all heavy-duty applica- tions, including minerals, aggregates and more. Capable of separating coarse feed material from finer materials, these vibrating screens are a low headroom design. Each screen is built with maxi- mum strength steel to withstand heavy loading and with the durability to give you longer wear life. MAX Series Vibrating Screens are available in a range of sizes from 6- x 16-ft. (1.8- x 4.8-m) to 8- x 24-ft. (2.4- x 7.3-m). They are designed to fit into any existing structure and operation with no rework. Backed by McLanah- an's years of industry experience, the company works with each customer to make sure that their MAX Series Vibrating Screen meets the specific requirements of their application. Safety in Mind MAX Series Vibrating Screens were designed with operator safety in mind. Sideplates feature cross beam inspec- tion ports that allow you to inspect inside tubes for failures when the tube is not visible due to abrasion resistant lining and eliminating the need for operators to crawl between decks for inspections. Foreign material that can corrode or abrade the inside of the cross mem- bers causing premature failure can be flushed out via cross beam inspection ports. The eccentric mechanism fea- tures jacking bolts in the mechanism tube to support the eccentric shaft during bearing change outs, eliminat- ing the need for a crane to suspend the shaft or the chance of the shaft tipping over and injuring workers, creating a safer work environment and decreas- ing downtime. Many of the features of the MAX Series Vibrating Screen improve maintainabil- ity for increased uptime. Independent cross members allow you to replace only worn tubes and not the complete deck frame. The direct drive system eliminates the requirement for a pivoting motor base to keep belt tension on start-up, which can be troublesome to maintain and eventually fail over time. Speed can be adjusted by simply replacing the motor sheaves and can be varied from 700 to 900 rpm without a change to the driven sheave. Wear Life The MAX Series Vibrating Screen is designed to be durable for the longest useful wear life and with maximum strength steel to withstand heavy loading. Sideplates are a fully bolted construction that reduces/eliminates crack propagation due to stress riser in the steel caused by welding and pro- vide the ability to quickly replace worn components without cutting. The eccentric mechanism is a custom one-piece machined eccentric shaft for maximum strength and force output. It features a labyrinth seal to deter oil contamination and eliminate the need for a standard breather, which is prone to plugging and failure. The quick- change spring kit allows the removal of the spring pack with only minimal ver- tical clearance and no overhead crane is required. This saves the customer money, as well as reduces downtime and increases worker safety while changing out the springs. McLanahan Corp., McLanahan Offers MAX Series Vibrating Screens Features/Benefits • Replacement cross members are shorter with machined and matched shims to allow easy installation in areas with limited clearance. • All shaft components on the eccentric mechanism slide onto the shaft, allow- ing for easy removal and installation of replacement parts. • Jacking screws on the motor base make belt tensioning easy. • Sideplates utilize A572 Gr. 50 plate as standard, giving it a 45 percent higher yield strength than traditional A36 plating. • Available in a range of sizes from 6- x 16-ft. (1.8 m x 4.8 m) to 8- x 24-ft. (2.4 m x 7.3 m). • Designed to fit into any existing structure and operation with no rework. • Backed by McLanahan's years of industry experience, service and support.
