Crawler Tractor Ups Production, Lowers Emissions

Liebherr’s 50-metric-ton (mt) PR 766 crawler tractor was designed for power, low emissions, efficiency, driver comfort, and durability, the company reported. With operating weights of between 46,200 kilograms (kg) and 54,200 kg, the tractor is the successor model to the PR 764. It is powered by a 310-kilowatt (422-horsepower) 8-cylinder V-engine.

The diesel unit in the PR 766 complies with Stage IV/Tier 4 emission standards, Liebherr reported. An optimized combustion process minimizes the particles while they are still inside the engine. The exhaust gas after treatment concept uses selective catalytic reduction. As a result, the new Liebherr diesel engines surpass Stage IV/Tier 4 emission standards without the use of a diesel particulate filter.

Dust Suppressants and Ground Control Agents

Quaker Chemical Corp. recently showcased its DUSTGRIP dust suppressants and MINETECH ground control agents.
DUSTGRIP JFP-95 presents as a solid material in a cylindrical shape and can be added to any system through a variety of prefabricated manifolds, the company reported. This eliminates the need for a liquid addition pump, and allows the strength of the suppressant solution to be adjusted quickly, or completely shut off. The solid material allows for a more compacted container size than a liquid dust suppressant, which means less storage area.

Russian Miners Set New Longwall Records

The Russian Yalevskogo mine, operated by the Siberian Coal Energy Co. (SUEK), recently set a world record for monthly coal production from a single longwall system. The mine produced 1.57 million metric tons (mt) or 1.72 million tons of raw coal during July. The mine, formerly known as Kotinskaya, surpassed its own national record of 1.4 million mt per month (1.54 million tons per month) for May.

Located in the Kemerovo area, the Yalevskogo longwall consists of a Cat face with an Eickhoff SL 900 shearer loader. The conditions are ideal for the 2,500-kilowatt (kW) SL 900, which cuts coal from seams with thicknesses that range from 2.4 meters (m) to 6 m. The combination of highly skilled miners and the powerful yellow SL 900 is a story of constant success, Eickhoff said.

Impact Cradle

The curved design of the Impact Cradle from Superior Industries eliminates the space between the belt and bed, adding extra protection. Designed to fit into an existing idler mounting footprint, it’s built to receive the blunt force of material flow at transition points in conveying systems, lessening the wear on the conveyor belt. Thick urethane segments absorb shock and dissipate contact energy, reducing conveyor belt wear and tear. Fitted for CEMA C, D and E idlers, the Impact Cradle is available in 20° and 35° trough angles for 5-, 6- or 7-inch diameter roll heights.

Flared Multirow Cage Mills

The F-Series, or Flared Series, Cage Mill from Stedman features a flared discharge opening, efficiently reducing the wettest and stickiest of materials, either abrasive or nonabrasive, without clogging. A multirow cage design takes material into the center of the inner-cage where it impacts on the cage impact bars and is hurled by centrifugal force into the path of the counter-rotating outer cage bars. This multistage reduction multiplies the impact force and results in higher first-pass yields. The cage mill is capable of producing a variety of product gradations by changing the mill speed. Feed sizes up to 3.5 inches are typical with capacities from 1 ton to 200 tons per hour (tph). A variety of linings are available for the unit.

4-Flexible Coupling Basics.jpg

Flexible Coupling Basics

Many different types of flexible couplings are available for use in the pump industry. Each has its own features and benefits, but all are required to perform three primary functions: connect two shafts, transmit rotary power and accommodate shaft misalignment. A document recently released by the Hydraulic Institute outlines pumping industry standard practices to select flexible couplings based on application requirements. Along with basic selection techniques, it reviews the most common styles of couplings found on pump applications across different industries today. It also provides the user with general guidance on the installation and maintenance requirements of each coupling type.

6-Gladiator Admittance image.jpg

Smart Level-detection Switch

The Gladiator Admittance Smart Switch Series, a state-of-the-art level probe, has been designed to operate in tough industrial environments. It detects the level of liquids, slurries, powders or solids in a tank or vessel. The unit is suitable for a broad range of products and dielectric constants and can operate at temperatures of up to 842°F. The unit measures the capacitance or “admittance” between a probe and the wall of the container. As the level of the product rises to the level of the probe, or drops below that level, the capacitance measured at the probe changes. The Gladiator detects this change and produces an output.

Flow Switch Protects Pumps

Engineers responsible for industrial water storage, disinfection or effluent treatment systems will find the FlexSwitch FLT93 Flow Switch reduces pump repair and extends pump life by detecting dry running conditions. Industrial wastewater treatment systems in mining applications depend on pumps to move water through storage, disinfection, effluent treatment and delivery. Pumps are expensive to operate and costly to maintain — especially when dry running conditions suddenly occur due to system variable demand, leaks, clogs or other problems that can end up damaging pump seals or bearings. The result can be emergency shutdowns, expensive service interruptions and major pump repairs, overhauls or even full replacement.
