VSI-9526 Vertical Shaft Impact Sand-Making Machine
The VSI-9526 is Baichy’s optimal solution for hard-rock processing conditions in Mexico. When handling highly hard and abrasive materials like basalt and granite, the wear parts of standard sand-making machines typically last less than 800 hours. By combining a "rock-on-rock" crushing chamber with high-chromium iron wear parts, the VSI-9526 extends the service life of wear components to 1,200–1,500 hours, reducing the cost per ton by approximately 35%.

Three key adaptations for the Mexican market:
• Motors customized to 60Hz/440V standards for direct connection to the local grid—no variable frequency drive (VFD) required;
• Standard hydraulic thin-oil lubrication station (featuring dual-pump redundancy, water cooling, and winter heating) to handle temperature fluctuations in Mexico's high-altitude mining areas;
• Spanish-language operation manuals and remote video installation guidance; direct shipping to the ports of Manzanillo or Veracruz.

II. Technical Highlights
2.1 Crushing Chamber — One-touch switching between "Rock-on-Rock" and "Rock-on-Iron" modes
The VSI-9526 Sand Crusher utilizes a dual-mode feed structure:
• Dual-feed (Cascade + Center Feeding): A portion of the material is ejected at high speed from the rotor and collides at high velocity within the crushing chamber against another portion of material fed via the bypass chute. Suitable for shaping hard rock; keeps the content of flaky and elongated particles below 5%.
• Center Feeding: All material is accelerated by the rotor and thrown against the impact liners. Ideal for manufactured sand from soft or medium-hard rock; maximizes production capacity.
For basalt/granite, a dual-feed mode is recommended; utilizing the "rock-on-rock" principle, material fragments collide with each other, significantly reducing the frequency of contact with metal wear parts.
2.2 Hydraulic Thin-Oil Lubrication Station — Industry-leading dual-pump redundancy design
| Function | Technical Parameters | Practical Value |
| Dual oil pump supply | 2 × 0.31 kW | Automatic switchover if one pump fails; no downtime |
| Oil pressure/flow monitoring | Real-time | Automatic shutdown on low oil; prevents shaft seizure |
| Water cooling system | Standard | Operates normally in 45°C heat (e.g., Mexican mining sites) |
| Winter heater | 2 kW | Cold-start protection for high-altitude mines in winter |
| Dual-canister filter | Standard | Maintains oil cleanliness; extends bearing life by 30% |
2.3 Rotor and Wear Parts — Robust performance for hard rock applications
For basalt (Mohs hardness 6–7, SiO₂ content 45–52%) and granite (Mohs hardness 6–7, SiO₂ content >65%), the VSI-9526 wear protection system features:
• Material distribution cone: High-chromium cast iron (Cr26), hardness HRC ≥58;
• Impact liners: High-manganese steel (Mn18Cr2); surface hardness reaches HB 500+ after work hardening;
• Rotor discharge tips: Tungsten carbide hard-facing; service life extended by 40%;
• Feed tube: Highly wear-resistant alloy steel lining; replacement cycle >3,000 hours.

III. Mexico Market Analysis and Adaptation Solutions
3.1 Background on Infrastructure Aggregate Demand in Mexico
According to Mexico's National Infrastructure Plan (Plan Nacional de Infraestructura), infrastructure projects under construction or in the planning stage for 2025–2030 include:
• Tren Maya (Mayan Train) extensions, requiring 0–5mm concrete sand;
• Phase II expansion of Felipe Ángeles International Airport (AIFA);
• Supporting roadworks for the Dos Bocas refinery;
• Highway upgrades across various states, which impose strict requirements on the continuous gradation and particle shape of manufactured sand.
As natural river sand resources become increasingly depleted, the market penetration of manufactured sand in Mexico is rising rapidly—from 18% in 2020 to approximately 35% currently. This trend is generating steady market demand for VSI sand-making machines.
3.2 Adaptation Solutions for 60Hz Power Systems
Mexico’s power grid operates at 60Hz, differing from China’s 50Hz standard. Failure to address this discrepancy results in: a 20% increase in motor speed, higher current, winding overheating, and accelerated bearing wear.
Solutions provided by Baichy:
• Customized Motors: Aligned with standards from WEG (Brazil) or Siemens’ Mexico plant; windings customized for 60Hz/440V operation, with rotational speeds matched to the 1,360–1,510 r/min range;
• Insulation Class: Upgraded to Class F (155°C temperature rise) to withstand high-temperature mining environments in Mexico;
• Overload Protection: Control cabinets equipped with thermal relays and phase-loss protection, adapted to 60Hz current characteristics;
• Alternative Option: If the client prefers to retain Chinese-made motors, a 132kW VFD (Variable Frequency Drive) can be installed to convert 50Hz to 60Hz, though this increases equipment costs by approximately $3,000–$5,000.
3.3 Logistics Plan
| Route | Port of Origin | Port of Destination | Shipping Duration | Container Type |
| Pacific Route | Qingdao/Shanghai | Manzanillo | 22–28 days | 1 × 40HQ |
| Atlantic Route | Qingdao/Shanghai | Veracruz | 30–38 days | 1 × 40HQ |
The VSI-9526 unit measures 4600 × 2350 × 2850 mm, fitting perfectly into a 40HQ high-cube container (internal dimensions: 12032 × 2352 × 2698 mm); it can be shipped without disassembly and is ready for installation upon arrival.

VI. FAQ
Q: Basalt is very hard; what is the service life of the VSI rotor components?
A: In dual-feed mode (rock-on-rock), the service life of the rotor's tungsten carbide-surfaced thrower tips is 1,200–1,500 hours, while the distributor cone (Cr26 high-chromium cast iron) lasts approximately 800–1,000 hours. We recommend shipping a spare set of wear parts with the equipment.
Q: Are 60Hz motors more prone to burnout than 50Hz motors?
A: No. The motor windings and wire gauges are specifically redesigned for 60Hz operation; it is not simply a 50Hz motor being derated for use. It features Class F insulation and dual protection via thermal relays.
Q: How is after-sales service guaranteed?
(1) Installation manuals and videos provided in Spanish;
(2) Remote video technical support via WhatsApp/WeChat;
(3) Chinese engineers can be arranged to provide on-site installation guidance in Mexico (additional cost applies);
(4) Replacement wear parts shipped via DHL/FedEx air freight, arriving in Mexico City within 3–5 days.
Q: Can it produce concrete sand that meets ASTM C33 standards?
A: Yes. When operating the VSI-9526 in dual-feed mode, the product's particle shape (high cubicity, <5% flaky/elongated particles) and gradation curve meet ASTM C33 requirements for manufactured sand. Sieve analysis reports from local Mexican laboratories are available for reference.
