For the bioeconomy to continue expanding, biomass must be produced and converted into biofuels in a cost-effective way. In September, Idaho National Laboratory (INL) bioenergy researchers helped meet those cost challenges by reducing the modeled cost of growing, harvesting, storing, transporting and preprocessing biomass from $149.58 per dry …

Hourly operating average costs for grinding alone, not including fuel, were assumed to be on average $216 h −1, and the required separate loader to feed the grinder was assumed to cost $102 h −1. Similar costs are reported by Refs. [6], [20], [21]. Given a fuel consumption of 100 L per hour a total cost of $93 h −1 was calculated.

A grinder that's too small for your feedstock, or production needs will slow your productivity, and a grinder that's too large can quickly suck up profits with operational costs disproportionate to its use. However, if you expect your operation to grow, a preemptive purchase of a larger grinder may be worth the investment in the long run.
According to their data, steam-exploded straw biomass needed about 2/3 less grinding energy for grinding to a given particle size than untreated straw biomass. 4.3. Cryogrinding. Cryogenic grinding is suggested as effective method for fine grinding of viscoelastic materials because the materials usually becomes brittle at low temperatures .

The processing of woody biomass waste piles for use as fuel instead of burning them was investigated. At each landing of slash pile location, a 132 kW grapple excavator was used to transfer the waste piles into a 522 kW horizontal grinder. Economies of scale could be expected when grinding a larger pile, although the efficiency of the loading operation might be …
