ACM Grinding Machine Manufacturer in Madhya Pradesh

Mecha Engineering Pvt. Ltd. manufactures ACM grinding machines, also called air classifying mills, at its own works in Village Meharbani, Behat, Saharanpur, and supplies them across Madhya Pradesh. Machines are designed, fabricated, assembled and trial run in that factory, then delivered to spice, soya and food plants, pharma units, chemical plants and mineral processors from Indore and Pithampur to Katni, Satna and Jabalpur.

Material is fed into the grinding chamber by a screw feeder and broken down by a high speed rotor fitted with hammers or pins. A built in dynamic classifier lets fine particles pass to the outlet and throws coarse particles back to the rotor for regrinding. The fines travel with the air stream into a cyclone and bag filter, where the powder is collected and the air leaves clean.

Our ACM mills work in a range of roughly 10 to 150 microns, and the figure is set by the classifier speed and the air flow rather than by changing a screen. Because the classifier runs on a variable frequency drive, the operator can move within that range from the panel. Share your target particle size and we will confirm it on a sample trial.

Spices such as turmeric, chilli, pepper, coriander and cumin, food products such as sugar, starch, protein powders and flours, pharmaceutical actives and excipients, and chemicals and minerals such as pigments, calcium carbonate, PVC and resin powders. It also handles heat sensitive and fibrous materials that need a fine, controlled result.

Yes. The continuous air sweep through the mill carries grinding heat away with the powder, which is why the method is called cool grinding. That protects colour, aroma and volatile oil in spices and keeps heat sensitive food and pharmaceutical products within specification. For fatty, waxy or very delicate products we supply a chilled air or liquid nitrogen cryogenic circuit.

Contact parts are built in MS, SS 304 or SS 316 depending on the product and the industry. Stainless steel with a polished finish is used for food, nutraceutical and pharma duty, while MS with hardened grinding elements suits minerals, fillers and industrial chemicals.

A pulveriser or multi mill sets the particle size with a screen, so the output carries a wider spread and usually needs sieving afterwards. An ACM uses a dynamic air classifier instead of a screen, so oversize particles are returned for regrinding and the powder leaves at a controlled top size in one pass. That matters when a specification names a micron figure rather than a mesh.

Yes. The standard supply includes a cyclone, a bag filter and a rotary airlock valve, so the powder stays inside the system and the production hall stays clean. High efficiency filter media, explosion vents and a nitrogen inert loop are available where the material or the area classification calls for them.

Yes, and we prefer it. Send a sample of your material with the fineness you are targeting. We grind it, record the particle size and the throughput reached and share the result, then size the machine on that trial rather than on an assumption about your product.

Price depends on the capacity, the fineness you need, MS against SS 304 or SS 316 contact parts, the dust collection arrangement, the cooling circuit and whether flameproof motors or a PLC panel are required. Because these change the figure widely, we do not publish a single price. Send your material and target fineness and a specification sheet with price follows the sample trial.

Yes. Our service engineers travel to Madhya Pradesh for erection, commissioning, classifier setting, operator training and wear part replacement. Beaters, liners, classifier wheels, filter bags and gaskets are held in stock at the works and couriered to your plant, and a recommended spares kit can be sent along with the machine.
