A Record Of The Combined Operation Of A 6525 Feeder, 900 Cone Crusher, And 7611 Sand Making Machine In Honduras

A Record Of The Combined Operation Of A 6525 Feeder, 900 Con

On the edge of the dense tropical rainforest of Honduras, a sand and gravel aggregate production line composed of Chinese-made equipment roars day and night. The "iron triangle" combination of a ZSW6525 vibrating feeder, a PYB900 cone crusher, and a VSI7611 vertical shaft impact crusher is creating an industry miracle, producing an average of 800 tons of high-quality manufactured sand daily. This article will take you on-site to uncover the technical details of this equipment combination.

Core Equipment of the Production Line

1. ZSW6525 Vibrating Feeder - Feeding Device

• Structural Features: Large feed opening (650 x 2500 mm), adjustable bar spacing up to 80 mm

• Field Performance: Frequency conversion maintains a stable feed rate of 100 t/h when handling high-humidity clay materials

• Innovative Modification: Addition of rubber cushions reduces vibration noise by 15 decibels

2. PYB900 Cone Crusher - Secondary Crushing

• Key Parameters: Maximum feed opening (80 mm), hydraulically adjustable discharge opening (steplessly adjustable from 15 to 50 mm)

• Basalt Processing Test: When the discharge opening is set to 35 mm, output stabilizes at 65 tons per hour

• Maintenance Highlights: Centralized lubrication system keeps bearing temperature below 55°C

3. VSI7611 Sand Making Machine - Fine Sand Forming

• Dual-Mode Operation:

• "Rock-on-Rock" mode: Fineness modulus 2.6-2.8 (for C30 concrete)

• "Rock-on-Iron" mode: Fineness modulus 2.4-2.6 (for C50 high-grade concrete)

• Energy consumption: When processing medium-hard rock, the power consumption per ton of sand is only 3.8 kW/h.

Joint Operation Record

Morning Operation (6:00 AM - 12:00 PM)

• Raw Material Preparation: The loader delivers raw material with approximately 8% mud content to the ZSW6525.

• Primary Screening: The bar screen removes 30% of the mud impurities (on-site screening efficiency measured is 92%).

• Secondary Crushing: The PYB900 automatically compensates for liner wear through the hydraulic system, ensuring a discharge particle size fluctuation of less than ±2 mm.

Afternoon Production (1:00 PM - 6:00 PM)

• Peak Sand Production: The VSI7611 operates in a mixed "Rock-on-Rock" and "Rock-on-Iron" mode.

• Quality Control: The online particle analyzer shows the finished sand grading:

• 4.75-2.36mm: 28%

• 2.36-1.18mm: 23%

• 1.18-0.6mm: 19%

• <0.6mm: 30%

• Sand Washing: The stone dust content after treatment in the bucket wheel sand washer is stable at 9.5%

Nighttime Maintenance (8:00 PM - 10:00 PM)

• Preventive Maintenance:

• Inspecting the VSI7611 rotor for wear (currently 1,800 cumulative hours, estimated remaining life 400 hours)

• Replacing the PYB900 hydraulic station filter (standard maintenance every 500 hours)

• Calibrating the eccentric block angle of the ZSW6525 vibrating motor

Special Measures for Tropical Environments

1. High Temperature and Humidity Solutions

Equipment Modifications:

• Upgrade all motors to Class F insulation (temperature resistance 155°C)

• Install anti-condensation heaters in the electrical cabinet

• The lubrication station is equipped with an oil-water separator.

2. Operational Data Comparison:

Parameters	Standard Operating Conditions	Rainy Season Operating Conditions	Solution
Cone Crusher Oil Temperature	45-50°C	55-60°C	Install Oil Cooler
Vibration Motor Current	28A	32A	5% Reduced Frequency Operation
Belt Life	6 Months	4 Months	Use Mildew-Resistant Material

3. Environmental Compliance Measures

• Dust Control: Pulse dust collector emission concentration <15mg/m³

• Water Circulation System: A three-stage sedimentation tank achieves an 85% wastewater reuse rate

• Noise Control: Sound barriers control plant boundary noise to below 65dB

Customer Testimonial: From Skepticism to Conviction

Interview with Project Manager Carlos:

"We were initially skeptical about the Chinese equipment, but three months of operational data convinced us:

• The comprehensive equipment utilization rate reached 91.7%

• Energy savings of 23% compared to the original European solution

• Manufactured sand fully meets ASTM C33 standards

In particular, the VSI7611 sand making machine can quickly switch between different grades of concrete sand by simply adjusting the rotor speed..."

Made in China: A Global Practice

This Honduras production line not only demonstrates the reliability of the ZSW6525+PYB900+VSI7611 equipment combination but also creates a new model for high-quality manufactured sand production in tropical regions. With the advancement of the "Belt and Road" construction, such successful cases are being replicated and upgraded around the world.
