Chain Conveyors and Bucket Elevators
Often used together, the MoveMaster chain conveyor and bucket elevator utilize the ‘En-Masse’ principle. This is where bulk materials are induced to move like a liquid through a dust-tight steel casing that can be designed horizontally, on an inclined plane, vertically, and around bends. This method avoids internal disturbance or pressure on the material and allows for discharge at any opening where the load is permitted to fall away from the flights. The conveyor’s versatility allows it to handle a range of capacities from 10 to 2000 tn/hr and it can also be used as a conventional drag chain. To ensure absolute quality control the chains are made from high-tensile alloy steel forgings. For maximum strength and service life the chain links are heat treated and the flights are precision welded to them.

Hydraulically Assisted Bearing
The Dodge hydraulically assisted ISAF bearing is ideally suited for large bulk-handling conveyors. The rugged bearing is easy to install and remove, features two superior sealing systems, and has housings and inner units made of ductile iron for added strength. It utilizes a built-in hydraulically assisted adapter-mounted installation and removal system. To install, simply slip the bearing on the shaft and apply hydraulic pressure to position the bearing on the adapter sleeve. Instead of the time-consuming process of mechanically rotating a lock nut, the hydraulic system quickly and easily pushes the bearing into position. Once installed, the full shaft contact offered by this mounting system reduces or eliminates fretting corrosion. To remove, simply apply pressure to the dismount piston to push the bearing off the adapter sleeve.

Dribble Chute Vibrator Application
A belt conveying system often requires cleaning of material from the belt. It is common to use a dribble chute to direct material caught by the secondary belt cleaner back onto the flow of material to minimize carryback. Minimizing carryback improves productivity, lowers cost, and aids in the efficient operation of a transfer point. The dribble chute vibrator application provides for a choice of electric vibrators and includes the vibrator, dribble chute mounting bracket with isolators, and brackets for attachment to the inside dribble sheet. Unique to this system is the positive attachment of the mounting bracket isolators to the user-provided angle mounting on the back of the external dribble sheet. This securely attaches the vibrator mounting and provides for a longer life.

Chantland MHS, Humboldt, IA 515-332-4045 www.chantland.com
Also known as a rope and disk conveyor, the aeromechanical conveyor is a high-capacity, totally enclosed unit that can convey at any angle—even vertically—up to 60 ft and at rates of up to 120 tn/hr, in a straight line, or in ‘round the corner’ or Z configurations. The conveyor offers most of the benefits of pneumatic conveyors but without the need for costly air filters to separate product from the conveying air. The high-speed unit uses a disk mechanism that fluidizes all flowable solids in a recirculating airstream that provides low-shear conveying of powders or particulates up to 5/8 in.

Conveyor Monitoring System
SmartArm is a wireless performance monitoring system for Iso-Flo vibratory conveyors that enables users to monitor asset or equipment shaker condition at any computer workstation. The system measures and reports speed and stroke to provide real-time analysis of shaker function, line-flow conditions, and trends at-a-glance. The SmartArm client also shows an alert when speed or stroke are out of tolerance. Empowering the shift from traditional time-based preventive maintenance to condition-based predictive maintenance, the system not only prevents downtime and reduces labor, but also provides the opportunity to improve process efficiencies.

Heavy-Duty Flexible Conveyors
The Flexifeeder line of flexible screw conveyors offers an expanded capability with less frequent maintenance. Each conveyor is matched to the individual customer requirement using both the company’s extensive installation database and complimentary lab testing. The use of controlled vibration at the inlet hopper eliminates material packing and tunneling and encourages more-even loading of the conveying screw. This, along with a simple robust drive system, results in a more uniform repeatable conveying rate and reduced maintenance.

Flexible Screw Weigh Batching System
This weigh batching system for mezzanines and other low-headroom areas utilizes low-profile flexible screw conveyors configured with motor drives at the inlet end of the conveyor, thereby reducing height and width requirements at the discharge end. The automated system is comprised of eight low-profile conveyors fed by roof-mounted storage vessels. Each group of four conveyors feeds either of two gain-in-weight hoppers that gravity discharge through the mezzanine floor to a ribbon blender on the plant floor. A system controller starts and stops each conveyor to weigh ingredients in sequence, then opens the slide gate valve to discharge the batch.
