MRC PCM-51 Cutting Mill

is a high-throughput sample preparation mill with variable speed (500–6000 rpm) for tough, fibrous, and temperature-sensitive materials.  It is engineered for rapid, reproducible size-reduction of heterogeneous solids using strong cutting and shearing forces. Samples are fed through an anti-splash hopper into a quick-clean grinding chamber where rotor knives act against cutting bars and a bottom sieve; once particles are smaller than the selected sieve aperture, airflow carries them into a 250 mL collecting bottle. With variable speed from 500 to 6000 rpm, feed size up to <25 mm, and final fineness from ~6.0 mm down to ~0.2 mm (sieve-dependent), PCM-51 handles continuous operation and one-step processing of long, fibrous materials—ideal for RoHS/WEEE sample prep and routine QA/production labs. Tool-less access to rotor, sieve, and hopper simplifies changeovers and cleaning; optional stainless or heavy-metal-free grinding sets support contamination-sensitive workflows.

Applications

Environmental & Waste Testing

• Solid waste, refuse-derived fuel (RDF), municipal waste streams
• RoHS/WEEE heavy-metal sample preparation (PCB fragments, cable jackets)

Polymers & Plastics

• Rubber, engineering plastics, dog chews, elastomers
• Pellets, sprues, cuttings prior to spectroscopy or digestion

Food, Feed & Agriculture

• Grains, seasonings, feed blends
• Straw, stalks, lignite/peat and other plant-based matrices

Materials & General Research

• Paper, wood, brittle composites, bones
• Routine sample prep before digestion, extraction, or imaging

Features

• Wide particle-size range: select sieves to reach coarse (~6 mm) through fine (~0.2 mm) outputs without pre-crushing.

• Throughput with control: 500–6000 rpm variable speed optimizes cutting energy for tough vs. heat-sensitive materials.

• Fast cleaning & changeovers: rotor, bottom sieve, and hopper remove/install easily—minimizing cross-contamination and downtime.

• Safer operation: electronic safety interlock prevents starts with the door open; anti-splash hopper improves housekeeping.

• Contamination-aware options: grinding sets available in stainless steel or heavy-metal-free steel for regulated analyses.

• Continuous processing: airflow assists discharge into a 250 mL bottle for steady runs on fibrous or long materials.

FAQs

• What fineness can I expect? With the appropriate bottom sieve, typical outputs range from ~6 mm down to ~0.2 mm. Very fibrous samples may require coarser sieves to maintain throughput.
• How do I reduce contamination risk? Choose the heavy-metal-free grinding set and keep rotor/sieve/hopper dedicated to specific matrices; quick disassembly streamlines cleaning between lots.
• Can PCM-51 process long, fibrous items? Yes—its cutting/shearing action and continuous discharge handle one-step processing of long fibrous materials without pre-cutting.
• Is speed adjustable? Yes, variable 500–6000 rpm lets you balance cutting energy and heat buildup across different materials.
• Which sieves should I stock? Common choices are 1.0–2.0 mm for general prep, 0.50–0.75 mm for finer work, and 4.0–6.0 mm for tough/fibrous feeds; exact selection depends on your method.
