March 20, 2018 - Canadian Biomass takes a look at the latest updates in hammer mill technology for reducing wood fibre in 2018.



Dieffenbacher

The ClassiSizer is used for preparation of organic substrates for biogas production, wood dust for energy and heat generation, wood-flakes for pellet production and many other applications. It reduces input materials to the desired particle size in one step. The material is fed from above into the impact chamber where it is resized with high kinetic energy by the fast rotating rotor and interaction of the particles. The final calibration of material is realized by screens, perforated according to the application. The end product is collected in two discharge boxes and fed out by screws. The ClassiSizer is able to process different and inhomogeneous input materials to variable sized final
particles.

KAHL
KAHL’s pan grinder mill is designed for the crushing of wood chips, wood shavings, sawdust and other lumpy biomass. This grinding process is appropriate for wet raw material. The capacity ranges from a few hundred kilograms up to 40 tonnes per hour and more. Appropriate for G30 and G50 wood chips pre-grinding for trouble-free fine grinding in traditional hammer mills. Its features include silent operation; minimum energy consumption; low space requirement; without aspiration system, cyclone, filter and exhaust air plants; no ATEX problems; low energy consumption; and no noise protection measures.

Andritz
The Andritz Series 6 HS Hammer Mill is engineered for today’s demanding applications and safety guidelines. The high-volume inlet features a reversible inlet baffle and optional pneumatic actuator while the heavy-duty rotor with long lasting pillow block bearings and temperature sensors is dynamically balanced for up to 2100 rpm operation. The reinforced flow thru housing is designed to withstand a .6 bar
internal pressure during an upset. Sliding access doors and slotted housing allow for easy maintenance, while a keyed door interlock system ensures safe entry only after the rotor has come to a complete stop.

American Pulverizer
American Pulverizer WBH series Wood/Bark Hogs process waste efficiently while saving on fuel and reclaiming valuable materials. Capacities range from 1 to 150 TPH depending on material, infeed size, and finished product size. WBH machines are available in 30” to 60” diameters with widths from 36” to 104.” Each machine is furnished with heavy-duty spherical roller bearings mounted in split steel housings and screen plates available in a variety of sizes. Available options include hydraulic housing opening for larger machines, v-belt or direct drive machines, and spider or disc design rotor with swing or rigid hammer arrangement.

CPM
CPM Biomass hammer mills are highly efficient machines, designed to meet the needs of almost any particle size-reduction task. They’re capable of fine-grinding friable and fibrous materials. Biomass hammer mills have standard and optional features for custom grinding and size-reduction solutions and total dependability. Meeting the particle size in the pellet is important and the HM series insures that this specification is achieved. The HM Series is a heavy-duty choice for grinding  chips, shavings, and oversized material. They’re built with double-wall box construction filled with vibration-dampening material; double-pivot, full-access doors; replaceable AR235 abrasion-resistant wear liners; a patented regrind chamber; and a mechanical steel tube base to keep your entire operation running smoothly.

West Salem Machinery
WSM’s Biomass Super Shredders are specifically designed for high volume milling of chips and other wood fibre materials, delivering process rates from 10-80 TPH.  These massive machines process a wide range of incoming green feedstock for improved drying and sizing for pellet manufacturing. Featuring rotor diameters up to 48” and length up to 88”; modular, adjustable tooling with rigid or swing hammers with replaceable inserts; large screen area with modular sizing screens for product size adjustment; heavy duty housing with interior wear liners; and pivoting case access for long life and ease of maintenance. Combined with WSM pre-screens, processing rates can reach 100+ tph. System integration into your wood handling system is no problem – complete infeed and outfeed options help you supplement your fibre supply.

Brunette
The Brunette BioSizer is a rugged high-speed wastewood grinder specifically designed for production of a fine consistent product. The Brunette BioSizer is built to be low maintenance with a high inertia rotor with four rows of staggered hammers to provide maximum bites per revolution. This grinder allows for processing of oversized ‘bush-grind’ hog fuel, trim blocks, wood chips, all converted to a small consistent product size for the biomass industry.
