Ball and
Sag mills
Sag mills
Heavy-duty grinding mill clutches with high heat dissipation are specially designed to provide quick, smooth starts of large inertia loads. Caliper brakes and couplings are also utilized.
| • | Automatic engagement and disengagement |
| • | Delayed engagement produces a “no load start” |
| • | No slippage at full running speed |
| • | Controlled soft-start acceleration |
| • | 100% efficient at rated speed |
| • | Standard, spring control, and deep pocket models |
| • | Protection against shock loads during start-up |
| • | 90°, non-intersecting shaft applications |
| • | Smooth, quiet performance |
| • | Provide high-ratio speed reduction in minimal spaces |
| • | Efficiency is easily increased by lowering ratios |
| • | With some ratios, there is resistance to back driving |
Ideal for ball and SAG mill applications
| • | Extra thick friction discs provide long life |
| • | High torque, low inertia design |
| • | Quick, simple installation |
| • | Low stress spined hub |
| • | Available with taper bore |
| • | Multiport air inlets available |
Bibbigard safety element torque limiters incorporate a number of safety element modules of a specific size mounted between two flanges and preset to release at a specified torque value in order to protect the drive system from expensive damage and lost production. They can be used with various types of drive medium many of which are available from Altra Industrial Motion. Bibbigard has been successfully utilized in many different industries where, subject to space availability, the release torque capacity is virtually unlimited.
| • | Accurate release torque repeatability |
| • | Simple fast manual re-engagement |
| • | Low-cost maintenance |
| • | Versatile mounting capability |
Spring applied, hydraulic released modular safety brakes
| • | 730 kN Braking Force |
| • | Compact, modular design no need for guarding |
| • | No pivot pins or long arms |
| • | “park-off” facility for fast pad changing without special tools |
| • | 3378cm2 pad area per caliper |
| • | Controlled release and inching possible |
| • | Robust, mine-ready design |

The G-Flex Series is an all-metal coupling that provides positive protection against the damaging effects of shock loads and vibration. Aluminum horizontal cover (T10), and all-steel vertical cover (T20) designs are available. G-Flex tapered grid couplings are an excellent choice where torsional flexibility/vibration damping are primary concerns.
| • | Easy to assemble / replace |
| • | Part-for-part interchangeable with industry standard tapered grid coupling designs |
| • | Coupling sizes 1020 through 1140 in-stock in a range of standard bore sizes |
| • | Shot-peened tapered grid flex element for long life |

| • | Conventional V-Belt drives |
| • | Narrow drives (Ultra-V) |
| • | Light-duty drives (FHP) |
| • | Synchronous Plus drives |
| • | QT Power Chain® synchronous belt drives |
Form-Flex metal disc couplings consist of two hubs, a spacer and two high strength carbon or stainless steel flexible discs. Modified and special designs are commonly supplied to meet specific application conditions. Available in carbon steel, stainless steel or with corrosion resistant coatings.
| • | No maintenance |
| • | Zero backlash |
| • | Close couple, spacer and floating shaft designs available |
| • | Easy interchangeability |
GC Series couplings feature unitized, straight-sided flexible discs for ease of installation. Up-to-date design targeted specifically for heavy industrial applications. These couplings provide increased torque capacity per size by taking advantage of the latest materials and design technologies.
| • | Unitized Flex Packs |
| • | Easier, faster installation |
| • | Interchangeable with industry standard designs |
| • | Fewer sizes to cover a full range of applications |
| • | Reduced spare parts inventory |
| • | Lower total cost of ownership |
| • | Special designs avaiable for higher-torque applications |
