| McLanahan Corporation offers a wide selection of crushers and feeders for mining and aggregate processing. Each piece of equipment is designed to make your operation more efficient, more productive and more profitable.
CRUSHER SELECTION
McLanahan specializes in a variety of crushing solutions for mineral size reduction, from very friable minerals, such as coal and salt, to hard rock, such as granite, and ore-bearing minerals, such as copper and iron. Minerals can be reduced in size, or crushed, at the primary, secondary and tertiary stages by crushing equipment that utilizes impact, attrition, compression or shear forces.
McLanahan crushers employ one or more of the basic reduction principles to achieve the desired size and shape at maximum volume and with minimum power consumption and wear on the machine. McLanahan custom engineers each crusher based on the crushing requirements determined through material testing in an in-house laboratory.
Cone Crushers
McLanahan Symons Principle (MSP) Cone Crushers utilize improved factors of performance, which are enhanced by the Symons Principle of crushing, as well as the latest hydraulic features and electrical features. This combination creates a truly modern, efficient, reliable and durable cone crusher that ultimately leads to a faster return on your investment.
DDC-Sizers
Sizers, specifically McLanahan DDC-Sizers, provide primary, secondary and tertiary reduction of friable, low silica materials. DDC-Sizers have a direct drive arrangement and low-profile design that allows wheel mounting for a movable configuration. This low-profile design also makes them well suited for installations where headroom is limited, such as underground mines. All segments and sizing combs in the DDC-Sizers are designed to be interchangeable throughout the machine.
Hammermill Crushers
McLanahan Hammermill Crushers provide superior reduction ratios for a variety of low to medium abrasive materials, including limestone, gypsum, coal, bauxite, phosphate, pet coke, carbon anodes and salt. Design elements, such as rotor speed, hammer type and grate configuration, can be custom engineered for various applications. Hammermills are used as both primary and secondary crushers.
Impact Crushers
McLanahan designs Universal Primary and Secondary Horizontal Shaft Impact (HSI) Crushers that can be used in the reduction of semi-abrasive minerals and are useful in processing deleterious material. Universal Impactors provide higher capacities than compressive crushers for a lower capital investment and can be used for processing quarried stone and a variety of minerals, as well as recycling C&D materials and more.
Jaw Crushers
Jaw Crushers are often used as primary crushers and are perhaps the most popular crusher worldwide. These compressive crushers are suitable for most any type of material. McLanahan Corporation produces two lines of Jaw Crushers – the classic Universal Jaw Crusher design, which is based on years of industry experience and success, and the Freedom Series Jaw Crusher, one of the most innovative designs in crushing.
Roll Crushers
McLanahan offers belt-driven Roll Crushers in four designs: Single Roll, Double Roll, Triple Roll and Quad Roll Crushers. Roll Crushers are built to handle primary, secondary and tertiary stage crushing of friable materials such as coal, salt, clay, bauxite, limestone and more. All McLanahan Roll Crushers provide substantial return on investment by operating at low cost and maximizing yield by generating minimal fines.
FEEDER SELECTION
Apron Feeders
McLanahan Apron Feeders are designed for varying applications, from light to severe-duty, that require moving high tonnages of coarse material too severe for other types of feeders. They provide a positive, consistent, forward material flow for a wide variety of applications including mining, quarrying, coal recovery and other mineral processing applications. Variable speed drives provide close control of the feed rate to a crusher or other equipment.
Vibrating Grizzly Feeders
McLanahan Vibrating Grizzly Feeders provide a continuous feed rate under a variety of loading and material conditions. Vibrating Grizzly Feeders are designed to take heavy shock loads from trucks, shovels and loaders. This type of feeder can be used in quarries, recycling, industrial processing, mining, sand and gravel operations, and a wide range of mineral processing industries.
Vibrating Pan Feeders
McLanahan Vibrating Pan Feeders are mounted on coil springs, providing high production with an even disbursement of the product. Vibrating Pan Feeders are ideal for specialty applications involving high-impact and surge loading when it is essential to meter the flow onto a conveyor.
Wobbler Feeders
Wobbler Feeders provide two functions – feeding oversized material at a controlled rate and scalping out the fines from the feed material. McLanahan Wobbler Feeders can be used to accomplish feeding and scalping for industries such as coal, salt, gypsum, phosphate, limestone, bauxite, coke, quartz, granite, aggregate and other mineral processing applications. They are especially good with wet, sticky material with high percentages of clay.
WEAR PARTS SELECTION
In addition to a wide selection of crushers and feeders, McLanahan also supports their equipment. Are the teeth on your crusher segments wearing quickly? Are you losing time and money by constantly building up teeth and hard-surfacing your roll segments and shells?
McLanahan has a solution for you. In addition to a wide selection of crushers and feeders, the company also offers wear parts solutions. Carbide impregnated weld-on teeth will increase your wear life, while minimizing your maintenance. In some cases, customers who have tried thes carbide impregnated weld-on teeth have increased wear life five or six times over their previous design.
Carbide impregnated weld-on teeth are application guided and solution driven. Maximizing wear life and reducing maintenance costs saves producers on both time and money. Additionally, the teeth are hand-welded, meaning that they are replaceable and spares are easily available from McLanahan to further extend the life expectancy of the base roll segment or shell.
Additionally, McLanahan is able to produce wear parts such as hammers, jaw dies and more for its line of crushing equipment.
CASE STUDY: Increased Production, Minimized Maintenance At New Acland Coal
McLanahan’s specially designed carbide impregnated teeth on the Secondary DDC-Sizers have drastically increased the wear life of the segments, allowing New Acland to process 5 million tons of product without having to change segments.
These improvements and reduced maintenance requirements led to both wash plants running 8,000 hours for the year. This was something New Acland had never been able to do before purchasing McLanahan DDC-Sizers, because every six to 12 weeks they needed to replace bearings or perform other maintenance tasks. They are now able to rely on their sizers to keep production going.
