There are discrepancies in the listingThe page calls the mechanism a burr grinder but also specifies interchangeable screen cloth and a 40 mm feed inlet, which is consistent with a crusher/pulverizer layout. The mechanism is not normalized beyond the supplier wording. The application list mixes industrial, commercial and generic location tags; duty class should be confirmed with the supplier before procurement.

There are discrepancies in the listingThe title says 60kg, but the structured HR-1500 capacity is 20–40 kg/h; 60kg is not promoted as throughput. The page states 68 kg as weight, 50 kg as gross weight in one detail field, and 60 kg as package gross weight. Only the explicitly labelled 68 kg machine weight is retained. Fineness is printed as 50–200m without a reliable unit; it is preserved verbatim and not converted to mesh or microns.

Before the final choice

Can you count G/s to Kg/h?

Mathematically, you can, but it doesn't prove continuous clockwork. Without a work cycle, you can't pass it off as passport performance.

Does engine power show flow?

No. It's important for engineering, but it doesn't replace proven performance on a given product and fraction.

How do you choose a stock?

First, measure the required peak and real cycle, then coordinate the stock with the supplier without going beyond the permissible model mode.

Translate the method to the working specification

Set the product, load, service, and infrastructure, then test the selected models under the same conditions.
