Precimax Engineers
Precision Since 1985ZED Bronze Certified – Govt of IndiaGrinding screens and mesh engineered for the masala and spice processing industry — built for fine, consistent particle separation in pulverising, grinding and filtering operations.
Precimax Trapezoidal Sieves are engineered with precision-formed apertures that reduce material-to-screen contact, allowing products to flow more efficiently through the sieve. The optimized geometry minimizes friction, reduces material accumulation, enhances airflow, and helps maintain cleaner processing conditions throughout the grinding operation.
Every screen manufactured to your mesh size, aperture shape and machine fitment — consistent output, run after run.
Conical/trapezoid perforation strips, 0.6mm–6.0mm diameter, for dry spice pulverisers (cumin, coriander, chili) — Chill Mill & Seed Mill compatible.
Rolled and seam-welded cylindrical screen rings with fine perforated mesh — direct replacements for pulveriser housings.
Precision-formed curved screen panels with reinforced frame ribs — fabricated to fit existing grinder housing profiles.
Cylindrical screen drums with square aperture perforations — available in multiple hole sizes for coarse to fine separation.
| Screen Type | Hole/Aperture | Form Factor | Best Suited To |
|---|---|---|---|
| 01 · Trapezoid Hole Screens | Conical/trapezoid, 0.6mm–6.0mm | Flat strips or fabricated rings | Dry spice pulverisers — cumin, coriander, chili (Chill Mill & Seed Mill) |
| 02 · Cylindrical Screen Rings | Fine perforated mesh | Rolled & seam-welded rings | Direct pulveriser housing replacement |
| 03 · Curved Screen Panels | To spec | Curved panel, reinforced frame ribs | Retrofitting existing grinder housing profiles |
| 04 · Square-Aperture Drums | Square grid, multiple sizes | Heavy fabricated drum | Wet processing — fruit pulp & high-moisture materials |
Full material, tolerance and open-area specifications for each type are detailed below.
Precimax Engineers manufactures and supplies hammer mill screens that keep masala grinding lines running at consistent output and fineness — the same precision-forming discipline applied to our tooling, translated into screen products built to handle continuous abrasive wear.
Trapezoid (conical) hole and square hole apertures — sized to your exact particle size and machine model.
All form factors covered — rings, curved panels and flat strip mesh for every pulveriser type.
Engineered for the abrasive, high-speed demands of continuous spice and masala grinding.
Stocked standard sizes and quick-turn custom fabrication to minimise your line downtime.
Structural integrity and geometric consistency are maintained across the full diameter spectrum — from fine 0.6mm apertures for powdered spice up to 6.0mm for coarser seed separation.
Equivalent range: 0.024″ – 0.236″ (inch conversions available on request for any custom hole size)

Exact figures vary by screen type, hole size and processing conditions — confirmed in writing at the quotation stage for your specific machine and material.
A straight-walled round hole holds a particle in full sidewall contact along the entire thickness of the sheet. The trapezoidal aperture is punched with a wider exit face than entry face — so once a particle clears the narrow entry point, sidewall contact drops off immediately, reducing drag and the chance of a particle wedging and blocking the hole.
Less wall contact per particle means lower resistance to flow, less material buildup around each aperture, and a screen that stays cleaner for longer between manual cleaning cycles.
Schematic — taper direction shown is set to your machine's flow orientation.
Dry spices — cumin, coriander, chili and similar seed/pod materials.
0.6mm – 6.0mm diameter (0.024″–0.236″), fabricated to your exact requirement.
Supplied as flat strips or fully fabricated rings.
Chill mills and seed mills.
Wet processing — fruit pulp and similar high-moisture materials.
Standard square grid aperture, sized to your process.
Supplied as heavy-duty fabricated rings for structural rigidity.
Fruit pulp extraction machines.
Raw sieve material is fabricated exactly to client specification. Conical or square hole strips are cut and finished to your machine's width, length and perforation requirements, then curved and seam-fabricated to match the exact curvature of your machine casing.
In short: your 0.6mm–6.0mm hole-size control, plus your specified width and length, equals a machine-ready fabricated ring — no on-site trimming or adaptation needed.
Custom widths and diameters are fabricated to order for any machine make or model — share your machine's casing dimensions for an exact-fit quote.
Large-scale conical-hole rings engineered specifically to handle the high friction and throughput of commercial Chill Mill machines.
| Width (W) | Diameter (dia) |
|---|---|
| 315 mm | 150 mm |
| 600 mm | 200 mm |
| 937 mm | 157 mm |
| 1200 mm | 257 mm |

Fabricated conical-hole sieves from Precimax are in active use on coriander and cumin seed milling lines — a direct reference point if your process runs similar dry-spice materials.
Whether it's a single replacement ring or a bulk production order, every hammer mill screen and pulverizer screen from Precimax Engineers follows the same disciplined workflow.
Your machine's casing width, diameter, hole-size requirement or a worn screen sample is reviewed to confirm exact-fit feasibility.
Piercing tooling and forming fixtures for the aperture pattern — trapezoidal, conical or straight-hole — are designed in-house for the target mill model.
Stainless steel or mild steel sheet is selected to suit the application — dry spice grinding, wet processing, or humid/coastal operating conditions.
Precision piercing/perforation followed by rolling and fabrication into strips or rings sized to your mill's casing and hole specification.
Hole size, pitch and ring/strip dimensions checked against your machine specification before packing.
Packed for safe transit and shipped — as a single replacement screen or as a scheduled recurring supply.
Stainless steel hammer mill screens, pulverizer screens and food processing screens from Precimax Engineers are exported to spice, masala and food-processing operations across the USA, Europe, UK, Canada, Australia, the Middle East and Southeast Asia. Screens are packed flat or rolled to prevent distortion in transit, with export documentation prepared ahead of dispatch.
Because these are a recurring wear item, many export buyers set up a standing or blanket order — talk to us about your change-out interval and destination for a supply schedule.
We accept single-ring and low-volume replacement orders as well as bulk/production quantities — share your machine model and quantity for a quote.
Yes. Since screens are a wear item, many buyers set up a standing or blanket order for periodic replacement — talk to us about your expected change-out interval and we'll structure a supply schedule.
Material and finish can be specified to suit your operating environment, including humid or coastal conditions — confirm your destination and conditions at enquiry stage.
Lead time depends on hole size, form factor (strip vs. fabricated ring) and quantity. Standard sizes ship faster than fully custom fabrications — we'll confirm an exact date at quotation.
Yes — share your machine's casing width, diameter and hole-size requirement (or the worn screen itself) and we'll fabricate an exact-fit replacement.
Tell us your pulveriser model, required mesh size and aperture type — we'll quote and supply.
