AR plate receives impact from heavy loads, abrasive and sharp material. Your equipment does not.

Typical applications for AR200 steel plate are cement mixer drums and fins, bulk material handling chute liners, skirt board liners, and screw conveyers. AR plate protects equipment against wear, although it is not for structural applications.

Typical AR plate products range from 200 to 500 in their name; for example, AR 200, AR 400, and AR 500. These numbers designate the hardness of the material in Brinell (BHN). The higher the hardness of the material, the more resistant it will be to abrasive wear.

AR400F has a nominal hardness of 400BHN. AR400F is used in equipment subject to abrasive wear. Examples are truck beds, crushers, hoppers, buckets, chutes, conveyor troughs, bulldozers, concrete mixer drums and excavators.

AR 200 plate is designed for general impact and abrasion applications, while AR 400F and AR 500F are designed to withstand high abrasion, low impact conditions. AR plate can be bolted down and welded onto the surface to protect your investment. Buffalo Wire will analyze your application and recommend you the most cost/effective AR plate.

Our High alumina ceramic liners are specially used in extremely highly abrasive applications. Ceramic liners provide optimum sliding surface for bulk material handling. It replaces UHMW and urethane sheets, and other plastic liners that distort and wear out. Ceramic liner’s low coefficient of friction and stable surface provide years of maintenance-free service. The tile size, shape and layout are determined by the customers’ protection requirements.

Ceramic liners are particularly suitable for many applications like:

• Deflectors / Impact Plates
• Chutes
• Bins / Hoppers
• Skirt Liners
• Stackers & Reclaimers

In many cases wear is caused by a combination of material impact and abrasion, Buffalo Wire offers a solution in which our high alumina ceramic is used in combination with rubber. This combination allows the ceramic to float in a shocking absorbing media, providing the ultimate protection against abrasion by the ceramic and impact by the rubber. Our in-house engineering, manufacturing and technicians in the field will allow us to recommend you the most beneficial solution for any given processing application, improve reliability and reduce cost.

Rubber liners solve your problems of impact, large and sharp material damage, and reduces noise. It is used to cover and protect surfaces that suffer extreme impact, shredding, and abrasion. Our rubber liners also reduces mechanical fatigue and fractures and is normally used when the material is large, irregular, or sharp. It has been successfully used to protect dozers, crushers, discharge areas, transfer of material areas, and cover truck beds that receive between 10 and 400 tons of material.

Rubber reduces noise and is lighter than AR plate. Our rubber liners can last up to three times more than plate when in contact with abrasive materials and up to five times more under impact conditions.

Available in thicknesses of 1”– 5” and may have a metal backing of ¼” or 3/8”. It can also be supplied with no metal backing. Rubber liners can be cut to 48” x 96” or 48” x 120”, or to your own sizing needs. Available in 45 – 50A hardness to withstand greater impact and they are used for larger sized particles. 65A hardness sheets are more widely used for abrasion and smaller sized particles.

Chromium Overlay Plate is intended for extreme abrasion, corrosion, and impact applications. The chromium carbide wear surface is a ceramic compound that is welded to a mild steel substrate. This provides a very resistant surface that will not separate. The primary purpose of the overlay is to protect the surface it is welded to from damaging wear and tear.
Common uses include:

• Chute liners
• Hopper liners
• Wear liners for dozers and buckets

This bimetallic plate (meaning two types of metals) consists of a mild steel base plate overlaid with chromium carbide. Typically, a ceramic compound formed of 30% chrome (chromium) and 5% carbon, chromium carbide that metallurgically bonds to the steel’s, forming a protective and durable surface that will not separate from the base metal.

Chromium carbide overlay steel plate is extremely hard, resistant to both wear and impact, and withstands high temperatures. As a result, chromium carbide plate is ideal for extreme wear applications, high temperature environments, and situations where corrosive problems exist. Chromium carbide overlaid plating also offers a high level of impact resistance.

Since it is composed of a combination of high chrome and high carbon, chromium carbide steel plate achieves unparalleled hardness. When the two metals join forces, they form chromium carbide crystals that reach 600 BHN on the Brinell hardness scale. That’s five times the hardness of unplated mild steel.

Urethane can solve your problems of wear by abrasion under wet conditions. It is not used under conditions of impact or sharp material. Widely used to protect surfaces that suffer extreme abrasion (not impact), typically in wet applications.

Eliminates sticking problems in hoppers, sand screw transporters, concrete mixers, silos, feeding and transport of material areas.

Urethane sheets are available in thickness of ½” – 4”. They are available in sizes 48” x 96” or 48” x 120”. They can also be cut to your specific size requirements. Available in hardness 55 – 90A.

UHMW high quality sheets promote the flow of material. With a low friction coefficient it is best used when the friction coefficient is of greater importance than wear and in applications where there is stickiness. Additionally, it provides protection to your equipment. UHMW is available in 65D hardness that is equivalent to 110A hardness.The UHMW virgin version offers better resistance to impact, while the recycled version offers a lower cost option for applications that are not too severe.

Available in sheets ¼” – 4” thick and 48” x 120”, or cut to your specific needs.

Urethane classifier shoes can be used for cover de-watering screws, as replacement wear parts on classifiers, and screw conveyors in OEM equipment. Classifier shoes protect metal surfaces and control many of the wear problems common to bulk aggregate handlers that turn and wash moving stone. Urethane classifier shoes are wear and corrosion resistant, lightweight, and easy to install.

They come in different styles and sizes. They can either have a metal backing or metal plates for welding. Classifier shoes can be impregnated with ceramic beads for greater wear protection or fortified with metal inserts that help secure fastening.
