The SLSF-G300 Ultra Fine Powder Crusher is a heavy-duty industrial mill designed for high-volume processing of dry brittle materials, ideal for medium to large-scale manufacturing facilities. With a fixed tooth disc diameter of 300mm (made of high-wear alloy steel, hardness: HRC 58-60) and a spindle speed of 3800rpm, it delivers exceptional crushing efficiency—processing twice as fast as small-scale models (e.g., SLSF-200). The machine features a three-stage system (coarse crushing, fine grinding, separation, and dust removal) and is constructed with wear-resistant 304 stainless steel for long-term reliability (service life of key parts: 5000+ operating hours). It also includes a vibration-damping base that reduces machine oscillation by 20% during high-speed operation, protecting the workshop floor and minimizing noise pollution.

Processes 5-20kg/h of material, with capacity adjustable via the feeding speed (controlled by a frequency converter). The crushing chamber is designed with a 15° inclined angle to accelerate material flow, avoiding clogging even when processing high-moisture (≤5%) brittle materials (e.g., semi-dry calcium carbonate).
Replaceable stainless steel sieves enable output ranging from 200 to 800 mesh, adapting to diverse industry needs: 6-20 mesh for coarse mineral aggregates, 80-120 mesh for chemical pigments, and 200-320 mesh for fine talc powders.
Total power consumption of 5.5kw (main motor: 5kw, dust collector: 0.5kw) reduces operational costs by 25% compared to same models (e.g., 7.5kw crushers with similar capacity). It also has a power-saving mode that automatically reduces speed when the feeding hopper is empty, cutting idle energy use.
A compact footprint (1250*860*1560MM) and 320kg weight ensure minimal installation space requirements—fits in most standard industrial workshops (ceiling height ≥2.5m). The machine is fixed with 4 adjustable leveling feet to compensate for uneven floors, preventing vibration-induced displacement.
Chemical industry: Grinding of organic/inorganic pigments (e.g., titanium dioxide, carbon black), resins (epoxy resin, polyester resin), and plastic additives (calcium stearate, talc filler).
Mineral processing: Pulverization of calcium carbonate, talc powder, kaolin, and gypsum—used in paper coating, paint, and rubber production.
Feed production: Crushing of grain (corn, wheat) and additive premixes (vitamin blends, amino acid powders) for livestock and aquatic feed.
Ceramic industry: Grinding of kaolin and feldspar powders for ceramic glaze formulations, where particle uniformity affects glaze smoothness.
Q: What certifications does it have?
A: The crusher is CE (EN 60204-1) and ISO 9001 certified, complying with international safety and quality standards. It also meets OSHA noise requirements (≤85dB at 1m distance) for workplace safety.
Q: Can it handle hard materials?
A: Ideal for materials with Mohs hardness ≤6, such as limestone, gypsum, and dolomite. For harder materials (Mohs 6-7, e.g., quartz), we recommend upgrading to our diamond-coated tooth disc (optional accessory) to extend service life.
Q: How often is maintenance required?
A: Routine inspection every 200 operating hours is recommended—checking tooth disc wear, sieve integrity, and belt tension. Replacement hammer blades come in a set of 8, and the installation process takes less than 30 minutes with the provided wrench tool. A maintenance log template is included to track service intervals.
