Single-mass (Brute Force) feeders use the ground to balance their destructive energies. Bypassing this floor damaging feature, two-mass machines use inbuilt moving mechanical assemblies that feed off one another. Back with a single-mass system, dual motors and weighted shafts crank out-of-balance parts, and then a linear stroke is imparted. For a two-mass vibratory feeder, one […]

The need to vibrate and process feed material exists across all industries. Even in the food sector, vibratory feeders ingest grain streams. The pharmaceutical sector is the same, with special feed chutes vibrating masses of tiny pills. For the mining industry, coarser material streams are the norm. On placing the emphasis of this post on […]

Essentially, these two competing vibrating screen types have developed differing material sieving motions. For linear vibrating screens, straight line screening dominates, with the equipment deck moving rocky material forwards and backwards. There’s also an amplitude component in the mix, which kicks the loosely packed aggregate up and forward. Circular motion screens simply replace that straight […]

Just about every mineral collecting maw is equipped with “brute” processing power. That’s as it should be, for all of the natural resources chewed up by those heavy duty feeders are raw and unrefined. Frankly, it takes an expert to recognize these rocky chunks. Indeed, gulped down a vibrating pan feeder, it’ll take time and […]

As higher volume throughputs force mining operations to play catch-up, older woven wire screening solutions are falling out of favour. In order to keep up with current and future demand, abrasion-resistant engineering plastics are being pressed into service. An engineered polyurethane screen, vibrating its heavy aggregate load, can handle abrasive forces that older screening solutions […]

For blinding issues on vibratory screens, look for a thick, mucous layer. It bridges the apertures and blocks them with dirt. Pegging issues are similar, except now there are tiny bits of material blocking the screen openings. But there will always be lumps of gunge in mining. It’s the same with solid material aperture blockages. […]

Ore sieving forces fall in line as soon as they reach a screen. At least that’s the theory. In reality, a few processing factors can adversely affect screening decks. Flow wetness is one of those factors. Bear in mind, this is a mining environment, which means there are uncontrollable geological elements in play. To deal […]

Mining equipment operates on the literal ragged edge of civilization. The gear is out there, in and under the remotest locales, providing state-of-the-art features. Built to function reliably under unpredictable conditions, the equipment shrugs off heavy impacts and high-volume abrasive collisions, all while delivering the very best productivity margins. Let’s see how a purchaser views […]

Let’s take a closer look at the variables that affect vibratory feeders. Remember, this is where the mining process starts, right after the aggressively effected excavation work has completed. The maw of the feeder admits a heavy stream of broken down minerals, the dual-excitation stage chews through the bulk material, and a variable frequency drive […]

Dewatering equipment is built to handle an unavoidable process side effect. No worries, though, a little groundwater is manageable. A pair of strong electrical pumps provide a fluid aggregate separation mechanism. On other sites, though, places where groundwater oozes out of every crevice, equipment suppliers know a working mine won’t stay viable unless a more […]
