Vibrating Screens / Vibration Screens
Mitool Equipments manufactures a complete range of industrial vibrating screens that classify, dewater, and size bulk materials with precision. Built for round-the-clock duty in steel works, collieries, quarries, mineral processing units, chemical and pharmaceutical plants, ceramic and glass factories, our linear-motion rectangular vibrating screens, dewatering screens, and grizzly bar screens are engineered for long service life with minimum downtime.
Screening performance depends on particle size distribution, shape, bulk density, flow characteristics, moisture, and loading method. Mitool engineers select the screen type, deck inclination, mesh aperture, and drive configuration based on each customer's actual feed characterisation — not from a generic catalogue. This application-engineered approach is what separates a screen that runs efficiently for ten years from one that needs rebuilding in two.
Types of Vibrating Screens manufactured by Mitool
Linear motion rectangular vibrating screen
Driven by two unbalance motors mounted at a fixed angle, rotating in opposite directions, these screens produce a perfectly straight-line vibration. The result is high throughput with accurate sizing — ideal for steel mill scale recovery, sinter plant feed preparation, sponge iron product grading, and aggregate classification. Inclination is typically 0° - 15° downward, with vibration-isolating springs that protect surrounding structures.
Grizzly bar vibrating screen
Heavy-duty parallel-bar screens designed to extract oversized coarse material from storage bins, hoppers, or run-of-mine ore before it reaches downstream crushers. Bars are spaced according to the cut-size required, and the entire deck is driven by unbalance motors to keep material moving and prevent bridging.
Dewatering vibrating screen
Specifically engineered to remove free moisture from slurries — used in coal washeries, sand-washing plants, and tailings handling. The deck slope is reversed (upward feed-to-discharge) to allow drainage time, and finer apertures combined with high-G vibration produce dry, conveyable material.

Frequently Asked Questions
A. Linear motion screens use two counter-rotating unbalance motors to throw material in a straight line — best for accurate sizing and heavy duty.
A. Selection depends on feed rate, particle size distribution, bulk density, moisture content, and the cut points required. Share these details and Mitool's engineering team will recommend the screen type, deck count, mesh aperture, and drive size.
A. A grizzly screen scalps oversized material from a feed stream before it reaches a crusher. The parallel-bar deck lets fines fall through while oversize is conveyed off the end — protecting downstream crushers from being overloaded by oversized lumps.
A. Yes — full SS-304 or SS-316 construction is available, with polished surfaces and sanitary clamps for the food, pharma, and chemical sectors.
A. Yes. Mitool stocks replacement mesh in MS, SS, polyurethane, and rubber, in standard apertures. Custom apertures are made-to-order within 2-3 weeks.
