In the production of sand and gravel aggregates, choosing the right sand-making equipment is crucial. The VSI7611 sand-making machine, with its efficient crushing, energy-saving and environmentally friendly features, and stable operation, is an ideal choice for small and medium-sized sand-making production lines. This article details the performance characteristics of the VSI7611 sand-making machine, its applicable scenarios, and how to configure a 60-200 t/h sand-making production line, helping you optimize your production processes and improve economic efficiency.
1. Core advantages of VSI7611 sand making machine
(1) Efficient crushing and stable production capacity
• Capacity range: 60-200 t/h (depending on raw materials and configuration)
• Feed particle size: ≤35mm, suitable for medium hardness materials (such as limestone, granite, basalt, etc.)
• Finished sand quality: good particle shape (high cubic ratio), adjustable fineness modulus (2.3-3.2), meeting different construction sand standards
(2) Energy saving and environmental protection, low operating cost
• Motor power: 110-132kW, low energy consumption, high crushing ratio
• Long life of wear-resistant parts: high chromium alloy throwing head and peripheral guard plate are used to reduce replacement frequency
• Environmentally friendly design: can be used with dust removal equipment to reduce dust pollution
(3) Flexible configuration and strong adaptability
• Can be operated alone or combined with jaw crusher, cone crusher, etc. to form a multi-stage crushing system
Supports dry and wet sand making processes to meet different market demands
2. 60-200 t/h sand making production line configuration plan
(1) 60-100 t/h small sand making production line
Applicable scenarios: small and medium-sized sand and gravel plants, commercial concrete mixing plant supporting facilities, construction sand production
Core equipment:
• VSI7611 sand making machine (main crushing)
• Jaw crusher (coarse crushing, such as PE500×750)
• Vibrating feeder (uniform feeding)
• Vibrating screen (screening finished sand, such as 3YK1860)
• Belt conveyor (material transportation)
Process flow:
Raw materials → Jaw crusher (coarse crushing) → VSI7611 sand making → Vibrating screening → Finished sand
Advantages: low investment, small footprint, simple maintenance
(2) 100-200 t/h medium-sized sand production line
Applicable scenarios: large sand and gravel aggregate plants, high-standard machine-made sand production
Core equipment:
• VSI7611 sand making machine (primary crushing)
• Jaw crusher (coarse crushing, such as PE600×900)
• Cone crusher/impact crusher (medium crushing, such as HPT300)
• Vibrating screen (multi-stage screening, such as 4YK2460)
• Sand washing machine (optional, to improve sand quality)
Process flow:
Raw materials → Jaw crusher (coarse crushing) → Cone crusher (medium crushing) → VSI7611 sand making → Screening → Sand washing (optional) → Finished sand
Advantages: high production capacity, excellent finished sand grading, and the ability to produce high-grade concrete sand
3. Key factors affecting production capacity
(1) Raw material characteristics
• Hardness: The production capacity of high-hardness materials such as granite and basalt is slightly lower (60-120 t/h), while the production capacity of medium- and low-hardness materials such as limestone is higher (100-200 t/h).
• Moisture content: Wet materials are easy to adhere, so the feed speed needs to be adjusted or drying equipment needs to be added.
(2) Finished sand requirements
• Fineness modulus: The production capacity is slightly lower when producing fine sand (2.3-2.6), and higher when producing coarse sand (3.0-3.2).
• Powder content: It can be adjusted by air screen or sand washing machine, but it will affect the overall output.
(3) Equipment maintenance
• Regularly check wear-resistant parts (throwing head, peripheral guard plate) and replace them in time when they are severely worn to avoid a decrease in production capacity.
• Optimize rotor speed: Adjust the speed according to different materials to improve crushing efficiency.
4. Successful Case Studies
Case 1: Limestone Sand Production Project (120 t/h)
• Raw material: Limestone (compressive strength ≤ 150 MPa)
• Configuration: PE600×900 jaw crusher + VSI7611 sand making machine + 3YK2460 vibrating screen
• Finished sand: Fineness modulus 2.8-3.1, stable production capacity of 110-120 t/h
Case 2: Granite Sand Production Project (80 t/h)
• Raw material: Granite (compressive strength ≥ 200 MPa)
• Configuration: PE750×1060 jaw crusher + HPT300 cone crusher + VSI7611 sand making machine
Finished sand: Fineness modulus 2.6-2.9, stable production capacity of 75-85 t/h.
The VSI7611 sand making machine, with its high efficiency, energy-saving, and flexibility, is an ideal choice for sand production lines with a capacity of 60-200 t/h. Whether it's a small sand and gravel plant or a large aggregate production line, the proper configuration of crushing and screening equipment and optimized production processes can achieve stable and efficient sand and gravel production.
