Hey there, if you’re running a operation that uses multi-deck vibrating screens (you know, those workhorses that sort gravel, minerals, or even recycling materials into different sizes), you know downtime here is basically money disappearing. The worst part? A screen shutting down because a tiny spare part is missing or beat to crap waiting to be swapped in. As someone who’s been supplying these screens for over a decade (not some random blogger—yep, I’m the guy who sells you the actual screen units), I’ve seen way too many crews mess up storing spare parts, leading to avoidable breakdowns. So let’s break this down: how to store your multi-deck vibrating screen spares right, no fluff, no corporate jargon just stuff that actually works. Multi Deck Vibrating Screen
First, let’s get one thing straight: multi-deck screens have specific parts that don’t play nice with random storage. We’re not talking about a generic bolt or a rubber gasket here. You’ve got things like screen media panels (the woven or rubber bits that do the actual sorting), eccentric shafts, tension springs, rubber buoys, maybe the motor mounts. Each of these has a Achilles’ heel—ignore it, and you’ll pull a part out of storage that’s already ruined before it hits the screen.
Let’s start with the big stuff first, because that’s where most people cut corners. The eccentric shaft—this is the part that makes the whole screen vibrate, right? If this gets rusty or bent, it’s basically paperweight. I’ve had a customer call me panicking because his stored eccentric shaft had surface rust so bad when he installed it, it wore out a bearing in two days. What’s the fix? Don’t just toss it on a shelf in a dusty warehouse. First, clean it off—use a degreaser, not just a rag with oil (wait, no, after cleaning, coat it with a light, non-detergent oil, not thick grease. Thick grease traps moisture. Wipe off the excess so it’s not sticky and attracting dirt. Then, prop it up on wooden blocks, not concrete or metal floors. Concrete can wick moisture from the ground, and metal can react with the shaft’s steel. Also, never stack anything on top of it—even a 50lb pallet will bend it, and you can’t tell a bent shaft just by looking. We’ve started giving customers these little prop stands when we sell shafts, but if you lost it, just use 4x4s cut to the right length.
Next up: screen media panels. These are the ones that get beat up the most—if you store them wrong, they’ll crack, stretch, or even get contaminated with material that makes them perform worse. Woven wire media, for example, hates being folded. A lot of guys stack them flat, but if they’re too heavy, the bottom ones warp. Wait, no—stack them vertically, like you’re standing a pile of plywood on its edge. But not just leaning against a wall—use a rack with slots that hold each panel evenly, so they don’t tilt and bend. For rubber or polyurethane panels? They degrade fast in hot, humid places. If your warehouse is 90 degrees in summer, that rubber will turn brittle in six months. So store these in a cool, dry area, not right next to a loading dock where the sun beats in. Also, keep them away from any petroleum products—even a drip of diesel or hydraulic fluid will eat through polyurethane, making it tear within a week of use. I’ve seen a guy dump a whole set of rubber panels because his forklift leaked fuel on the storage shelf—total waste.
Then there’s the tension springs and rubber components. Tension springs are crazy strong, but they rust like crazy, and if they’re stretched out in storage, they lose their tension power. Don’t hang them on a nail in the wall—hang them in a relaxed state, so they’re not pulled. And again, coat them with that light oil to prevent rust. Rubber buoys, vibration isolators, those little rubber bits that cushion the screen’s frame? These are even worse—they dry rot if stored in sunlight, or get squashed if you stack heavy stuff on them. Keep these in sealed plastic bins, labeled clearly, and tuck them away from any UV light. Pro tip: if you’re storing rubber parts long-term (more than 6 months), throw a small desiccant packet in the bin—absorbs any leftover moisture, no mildew, no rot.
Now, small parts—bolts, nuts, washers, gaskets. These are easy to lose, easy to mix up. I can’t tell you how many times a customer has called saying “we lost all the bolts for deck 2” because they dumped a whole box of small parts into a bin and they got mixed with the hardware for their bulldozer. Here’s the trick: group parts by which deck they belong to. Multi-deck screens usually have 2, 3, even 4 decks, right? So each set of bolts for deck 1 is a different size than deck 3. Use clear plastic storage bags (not opaque—you can see what’s inside without opening) and label each one with the part number, which deck it’s for, and what machine it’s from. We add part labels to every spare part kit we sell, but a lot of guys throw those away. Don’t. Tape those labels to the bag, and write the machine ID on it too—if you have multiple screens, you don’t want to grab the wrong bolts for your 3-deck screen when you’re working on a 2-deck one. Also, keep small parts off the floor. Even if your warehouse is clean, a spilled bolt can roll under a forklift and get crushed, or get coated in dust and grease. Store them on wall-mounted pegboards with hooks, or in drawers with small compartments. Mark each compartment with a label, so you don’t have to dig through a pile of washers looking for the right size.
Wait, let’s talk about something most people forget: inventory checks. It’s not just storing the parts—it’s checking them every 3 months, especially if you’re storing long-term. I had a customer last year who stored a set of spare screen panels for 18 months, and when he pulled them out, half the woven panels were rusted through because the oil we gave him wasn’t reapplied. If you do a quick check every quarter, you can catch rust, warping, or rotting before the part is needed. And when you check, don’t just look—run your hand over the eccentric shaft to feel for rough spots, bend a small part to make sure it’s not brittle, spin a spring to see if it’s still springy. That takes 10 minutes, and saves you from a $500 part that’s useless when you need it.
Also, let’s address the “I don’t have space for fancy storage” crowd. Not everyone has a climate-controlled warehouse. If you’re storing parts outside (I don’t recommend it, but sometimes you have no choice), invest in weatherproof plastic covers and elevate the parts off the ground with pallets. Cover the eccentric shaft with a tarp that’s not touching the metal, so moisture doesn’t get trapped under it. For screen panels, use a heavy-duty canvas cover, and weigh down the edges so wind doesn’t blow it off. But here’s the thing: outdoor storage is a last resort. I’ve seen parts ruined in a single rainstorm, so if you can move them inside, do it.
A quick mistake I see all the time: people store spare parts right next to the actual screen on the plant floor. That seems convenient, but the plant floor is dusty, greasy, and has forklifts zooming around. A part can get knocked off a shelf, stepped on, or covered in sludge, making it unfit. Store spares in a dedicated storage area, not the same spot as your running equipment.
Now, let’s wrap this up with why it matters. A multi-deck vibrating screen is a big investment—we’re talking tens of thousands of dollars, easy. A spare part costs a fraction of that, but if it’s stored wrong, you’re looking at a 12+ hour downtime while you wait for a new part, plus lost production. That’s way more than the cost of doing storage right.
If you’re out there buying spares for your multi-deck screen, or you need to make sure your current stock is stored correctly, hit me up. We’ve been supplying these screens and their spares for years, so we know exactly what parts you need and how to store them to last. Whether you’re a small quarry or a big recycling operation, we can hook you up with the right parts and even help you set up a simple storage system that doesn’t require a fancy warehouse.
