14CM Series Continuous Miners

The JOY 14CM continuous miner product line has been developed to meet the high productivity requirements of today’s underground mining industry. Providing the ideal combination of cutting power, proven components and reliability for lower to mid-seam applications in a variety of materials. Built to withstand the rigorous conditions, the 14CM offers optimum service life and return on investment. The basic elements of each continuous miner are similar in design, following field proven philosophies perfected by Joy over the years. Each machine employs Joy’s multi-motor concept with outboard access to motors, gearcases, controllers and other major components. The philosophy calls for the isolation of major components for easier troubleshooting and maintenance. The continuous miners use individual motors with direct drive transmissions to power the cutter, traction, gathering and hydraulic systems. This permits service or repair quickly and easily, thus reducing downtime and maintenance costs. 

Application Specific Cutting Systems 

The 14CM accommodates a wide variety of cutting options. Available in solid head or RipperveyorTM models and in drum diameters ranging from 30 to 44 inches or 762 to 1117 mm, the cutting system can be sized to match seam conditions. Rated cutting power as high as 590 hp (440 kW) is available within this product line. Application Specific Cutting Systems

Optimum Fluid Control

A standard feature on all miners, JOY Hydraulic manifolds reduce hose assemblies and fitting count by over 30% from previous manifolds, which significantly reduce leak points.  All serviceable parts for a circuit are in one common location and all pressure check points allow gauge connection and disconnection while the pump is running. Bolt-on caps permit easy access for troubleshooting or replacement on hydraulic or water segments.  Joy’s new main control valve design has 25% higher flow and 30% higher pressure capability. Screw adjusted relief cartridges are now standard. Improved sealing in all areas means significantly less oil leakage. A proportional control valve option is available that interfaces with FACEBOSS to optimize cutter motor feedback. 

Proven Conveyor System

Dual direct drive motors power the 14CM conveying system loading arms and chain via reliable, time-tested transmissions. The conveyor chain includes universal links to prolong chain life, and the cam style adjusting mechanism automatically compensates for chain slack as the conveyor swings. Recent enhancements to the system include increased abrasion resistant material use along the chain path and loading arms.

Wethead Cutterhead Systems

The JOY Wethead continuous miner cutterhead incorporates a fine spray behind each cutting bit of the cutter drums to reduce the potential for frictional ignitions and to reduce respirable dust levels. The water spray acts as both a cooling and wetting agent in order to address both issues at the same time. Also, the sprays provide lubrication that substantially improves bit life. The Wethead does all this while potentially consuming less water than the standard miner dust sprays. The heart of the system is a back-to-back carbon-face water seal designed to run dry for extended periods of time and last from rebuild-to-rebuild before refurbishment is necessary.
