The Mechanics of En Masse Elevating
En masse movement is the term used to describe the unique method of conveying bulk materials cleanly, gently and economically.
Movement of the chain when buried in the material will induce the whole mass to move forward gently in a solid column. Elevator design permits the column of material to be moved vertically or on an inclined plane.
The elevator feeds itself at any point with a uniform load. The skeletal flight configuration induces the material to flow in a solid, placid column.
There is no internal disturbance or pressure on the material and the load can be discharged at any opening, where it is permitted to fall away from the flights.
STOCK REDLER elevators are manufactured in a standard range of sizes from 200mm wide upwards, which enables them to meet every requirement.

The Benefits of Stock Redler En Masse Handling

Cost Effective

• Capital costs prove very competitive with other forms of handling equipment, thus giving quicker 'payback period'.
• Power running costs are significantly lower than most other forms of equipment, i.e. they can be as low as one tenth of dense phase conveying.
• Low cost maintenance. Stock Redler En Masse Conveyors and Elevators

Labour Saving

• Manual to fully automatic control of single or multiple machine systems provided by proven BASIC control systems.
• No specialised maintenance staff required.

Environmentally Acceptable

• Totally enclosed machines and transfer points of dust-tight and weatherproof construction.
• Safe as all moving parts are totally enclosed.

Versatile

• Specialised features of 'en masse' equipment offer versatility to plant layout.
• Handles virtually all types of dry bulk products.

Size

• Size and duty comparable with alternative forms of handling equipment.

Gentle Handling

• Material moves 'en masse' slowly in a solid placid column with the conveying elements: thus degredation is virtually eliminated.
• Chain design permits material column to change direction through bends, without degradation.

Proven

• Over 60 Years experience of handling hundreds of bulk materials world-wide within a wide range of industries.

Elevator Construction
1. Drive and Tension Terminals
Fitted with precision machined hardened steel sprockets and wheels running in self aligning ball or roller bearings. Shaft sealing is affected by special glands.

2. Drive Arrangements
A typical drive arrangement is an integrally mounted geared motor driving the sprocket shaft through a totally enclosed chain drive incorporating a shear pin overload safety device. Larger drive assemblies incorporate a motor coupled to a gear unit through a flexible or fluid coupling all mounted on an independent base.

3. Conveyor / Elevator Casing
Fabricated from hot rolled strip mill steel. Chain runners manufactured from special steels are provided where required. All cross sectional figures are ground after assembly to ensure perfect alignment. Inlets, outlets, inspection ports are pre-cut to ensure accuracy and quality finish.

Chain
STOCK REDLER chains are produced entirely in our own factories under strict quality control from high tensile alloy steel drop forgings, fitted with precision welded flights. The links are case hardened to give increased wear protection.

Safety Features

• Overload Device - Electronic or mechanical shear pin.
• Choke Detector - where appropriate these are fitted at the final outlet of the machine.
• RoCon - It is recommended that all conveyors and elevators should be fitted with a STOCK REDLER RoCon speed switch.

Special Features
Predominantly when handling wet, abrasive or corrosive products, machines can be or are fitted with:

• Stain resistant chain pins
• Internal replaceable liners
• i.e. EN18 - Red Diamond - Nihard - Manganese
• Special casing i.e. galvanised - Cromweld - Stainless Steel

Typical Dimensions and Capacities
Requires experienced consideration of chain speed, machine configuration and characteristics of the product to be handled. Simple machines handling free flowing products will accept a higher speed and throughput than a similar sized machine with bends handling a sticky abrasive product.
