Which sand making machine produces 1mm output size?

For customers needing strict 1mm fine finished sand, VSI6X vertical shaft impact sand maker is the top pick. Used alongside closed-circuit screening and material return processing, this machine steadily turns out premium fine sand ranging from 0.8mm to 1mm. If you run small-to-medium output lines for 1mm sand, go with the VSI5X series instead. These two machine ranges are ’s core fine-sand production models, widely processing limestone, river pebble, granite and quartz into 1mm sand for dry-mix mortar, casting and construction material use.

As ’s 6th-generation upgraded unit, the VSI6X is built specifically to make high shares of fine sand. It comes with a four-port deep-chamber impeller, which hits stone more often than old three-port rotors. Raw rock gets repeatedly crushed and ground inside the crushing cavity to boost the percentage of 1mm finished grains. Operators can switch between rock-on-rock and rock-on-iron working modes with one click. Rock-on-rock relies on stones crashing against each other, producing round, flake-free 1mm sand with consistent grading. Rock-on-iron works better for hard raw materials to quickly crush stone down to required fine size, so you can shift modes based on your raw stone’s hardness and target grain size.

Available models include VSI6X8018, 9026, 1150 and 1263, with hourly output from 100 tons up to 583 tons. Small and mid-sized sand plants usually pick 8018 and 9026, while large-scale production lines use 1150 or 1263. Keep feed material below 50mm after primary fine crushing, then feed into the VSI6X. Pair it with circular vibrating screens for closed loop work: any oversize grit bigger than 1mm gets sent back into the machine for re-crushing, locking finished sand steadily at around 1mm.
On maintenance and wear parts, the VSI6X uses split-type wear liners that can be flipped around for reuse after partial wear, lifting wear part service life by nearly 50% and cutting running costs for bulk 1mm sand production. It has an automatic thin oil circulation lubrication system with air cooling to keep bearings at steady temperature and avoid unplanned downtime from overheating.

A built-in lifting fixture on top lets workers replace impellers and impact blocks alone without large lifting gear, easy for round-the-clock continuous fine sand production. Positive-pressure dust sealing stops fine sand dust from seeping into bearing housings, so the machine breaks down far less often than rival models during long-term fine sand runs. You can also fit pulse dust collectors to gather ultra-fine dust; collected fines mix into final 1mm sand to improve overall raw material usage and cut site dust pollution.
For small plants making under 100 tons of 1mm sand per hour, choose  VSI5X sand making machines. This proven 5th-gen model has deep-cavity rotors and split hammers – only worn hammer sections need replacing to save spare part cost. Its hydraulic opening design unlocks the machine shell in seconds for fast maintenance. Hourly capacity spans 70 to 640 tons, making

VSI5X7615 and 8522 ideal picks for small mortar factories and mineral processors. When matched with closed-loop screening, it also delivers stable 1mm fine sand.

Standard production flow for consistent 1mm sand: Jaw crusher reduces raw stone to 5~20mm → VSI6X sand shaping → S5X circular vibrating screen sizing. Oversize top-screen material recycles back for re-crushing, and undersize material is finished sand between 0.9~1mm. supplies full sets of crushing, screening and dedusting equipment in one package; dozens of domestic dry mortar and quartz sand projects run this setup. Final grain size varies only ±0.1mm, fully meeting strict 1mm sand specs. Compared with outdated PCL sand crushers, VSI6X raises sand yield by over 12% with much higher 1mm fine sand ratio and lower overall power cost in mass production, standing as ’s best option for large-volume 1mm fine sand manufacturing.
