Subject: Reducing Downtime & Wear Costs: FDAApproved Impact Crushers at Competitive Price Points

1. PAINPOINT DRIVEN OPENING

Your current crushing circuit is likely bleeding capital. Are you facing these operational bottlenecks?

• Unplanned Downtime: Frequent bearing failures or rotor lockups in standard crushers cost your operation an average of $2,500 to $5,000 per hour in lost production.
• Contamination Risks: In foodgrade mineral processing (e.g., calcium carbonate, salt, gypsum), standard crushers introduce ferrous contamination, leading to rejected batches and compliance fines.
• High Wear Costs: Abrasive materials are destroying liners and blow bars every 300400 hours, driving your costperton above $0.85.
• Inconsistent Product Shape: Poor cubicity in your final aggregate or powder is reducing your market price by 1520% compared to spec material.

How can you achieve high reduction ratios without compromising material purity or your bottom line? The answer lies in equipment designed for both sanitary standards and industrial throughput.

2. PRODUCT OVERVIEW

Our FDAApproved Impact Crushers are specifically engineered for industries where material purity is nonnegotiable and operational costs must be minimized. These are horizontal shaft impactors (HSI) constructed with 304L or 316L stainless steel contact surfaces and foodgrade seals, designed to process dry, friable materials.

Operational Workflow:
1. Feed: Material enters the feed chute via a vibrating feeder or conveyor.
2. Primary Impact: Material strikes the highinertia rotor blow bars, achieving initial size reduction.
3. Secondary Reduction: Material is hurled against the adjustable apron (breaker plates) for further crushing.
4. Cascade Chamber: Oversized particles recirculate internally until they pass the discharge gap.
5. Clean Discharge: Finished product exits via a sealed, dusttight housing, free from lubricant or metallic contamination.

Application Scope:

• Ideal For: Foodgrade salt, sugar, limestone, gypsum, dry chemicals, and pharmaceutical excipients.
• Limitations: Not suitable for wet, sticky materials (moisture >5%) or materials with a compressive strength exceeding 150 MPa.

8. FAQ

Q: How does the FDA approval affect the crusher’s ability to handle abrasive materials like limestone?
A: The FDA approval applies to the contact materials (stainless steel) and seals, not the crushing mechanism. The highchrome blow bars and reversible liners are designed for abrasive materials up to 150 MPa. The stainless steel housing is thicker (1/2" vs. 3/8") to resist wear.

Q: Can I retrofit my existing carbon steel impact crusher with FDAcompliant parts?
A: Generally, no. The rotor, housing, and seals must be designed for stainless steel to prevent galvanic corrosion and maintain sanitary welds. Retrofitting a carbon steel frame is not costeffective and voids the purity guarantee.

Q: What is the lead time for a Model 2000?
A: Current lead time is 1214 weeks from order confirmation. Expedited production (8 weeks) is available for a 10% surcharge.

Q: Does the competitive price include the VFD or hydraulic apron?
A: No. The base price includes a fixedspeed motor and manual apron adjustment. The VFD and hydraulic package are optional upgrades, as listed in the Commercial Considerations section.

Q: How do I ensure the crusher meets my specific product gradation requirements?
A: We offer a free material test at our facility. Send a 500 lb sample, and we will provide a certified gradation curve and wear life estimate within 10 business days.

Q: What is the warranty on the FDAapproved seals?
A: The doublelip seals with nitrogen purge are warranted for 2 years or 4,000 operating hours, whichever comes first, against leakage. The blow bars are considered consumables and are not covered under warranty.

Q: Can this crusher handle wet materials if I add a dryer upstream?
A: Yes, but the crusher itself is designed for dry materials (<5% moisture). If you install a dryer, ensure the feed temperature does not exceed 150°F (65°C) to protect the seals and bearings.
