Cement Bag Shredder Machine for PP Woven Sacks

Yes. Woven cement sacks are polypropylene tape fabric — the same raffia-grade PP used in woven sacks across industries — and PP recyclers wash and pelletize shredded bag material into reprocessed granules for new woven products and mouldings. The barrier in practice is never the polymer; it is the form. Loose dusty bags are uneconomical to transport and unpleasant to handle, so recyclers want them shredded and compacted first. That is precisely the job the cement bag shredder does at your plant. See our PP plastic shredding solution for the wider polypropylene route.

Cement dust is abrasive, so it accelerates blade edge wear — that is physics, on any machine. Two things keep it manageable: shake bags out at collection so the bulk of the dust never enters the chamber, and schedule periodic blade sharpening as routine maintenance rather than waiting for output quality to fall. Raj Electricals machines are all-metal construction with no plastic parts, built for exactly this kind of dusty industrial duty, and we support blade service and spares pan-India from Mumbai.

Because both are violations with real consequences. Open burning of plastic is prohibited under air quality and waste management rules, produces visibly toxic smoke, and is one of the easiest violations for an inspector — or a neighbour with a phone — to document. Burying mixes plastic into soil and debris permanently. Meanwhile EPR provisions push cement brands and large consumers to demonstrate recycling routes for plastic packaging. Shredding flips the equation: instead of paying a compliance risk, you produce a material PP recyclers collect and pay for.

Think in weight and handling cost, not just bag count. Weigh a bundle of your empty bags to get a per-bag figure, multiply by daily consumption, and compare the shredder’s running cost against what the loose mountain costs you today — yard space, housekeeping labour, audit findings and forgone scrap value. Large RMC plants emptying thousands of bags daily justify a dedicated machine easily; smaller sites sometimes share one machine across a cluster or shred in weekly batches. Send your daily bag count via the enquiry form and we will size it honestly — including telling you if a smaller machine is enough.

The dual shaft principle handles the whole PP bag family, but configuration matters: FIBC jumbo bags are much heavier fabric with lifting loops and need to be sized accordingly, while non-woven bags run on the dedicated non-woven bags shredder. If your operation generates a mix — cement sacks, jumbo bags, non-woven packaging — tell us the proportions and we will recommend either one appropriately configured machine or separate machines per stream.

Every machine is quoted to the job. What moves the number is capacity, throat size, motor rating, MS or SS construction and the automation you add — a blower, a conveyor, a control panel. Our guide to what drives machine cost walks through each of those; send us your material and daily volume and we will size the machine and quote it, usually the same day.

We do. Raj Electricals provides installation and maintenance service on site, and machines run at client locations across India with spares dispatched from our Mumbai works. For remote project sites, we recommend ordering a spare blade set with the machine so scheduled sharpening never waits on a courier. Export buyers are covered too — motors are supplied for your country’s voltage and frequency, with sea-freight packing. Contact us with your site location and we will confirm service logistics before you order.

Yes — and with bags it is worth doing, because dust levels and bag condition vary site to site. Send a gunny or two of your actual empty bags to our Andheri East works and we will run them through the machine live or on a recorded video trial: you see the feeding rhythm, the shredded output size and how your specific bags behave. It is the quickest way to validate the machine against your material before signing a purchase order. Book a trial slot.
