In the field of mining crushing and manufactured sand production, the selection of sand making machines directly determines the efficiency of the production line, the quality of the finished sand, and long-term operating costs. As experts with 20 years of experience in manufacturing mining crushing equipment, we have found that many customers face confusion when selecting equipment.
This article will systematically analyze the characteristics of five mainstream sand making machines from a professional perspective and provide a proven selection decision framework to help you find the best solution that truly matches your production needs.
Comprehensive Analysis of Five Major Sand Making Machine Types
Impact Crusher (VSI Sand Making Machine)
1. Impact Crusher (VSI Sand Making Machine)
- Working Principle: Uses the stone-on-stone or stone-on-iron principle, accelerating and throwing materials out through a high-speed rotating impeller, causing them to collide and break against the surrounding liner or material layer.
- Core Advantages: Excellent finished sand particle shape (mostly cubic), continuous gradation, adjustable fineness modulus, very suitable for producing high-standard construction sand.
- Applicable Materials: Medium and high hardness ores, such as granite, river pebbles, basalt, etc.
Heavy Hammer Crusher
2. Hammer Crusher
- Working Principle: Relies on high-speed rotating hammers to impact and crush materials, with the crushed material discharged through the sieve plate gaps.
- Core Advantages: Large crushing ratio, high output, can complete medium crushing and sand making in one step, and has a lower investment cost.
- Applicable Materials: Medium and low hardness, low abrasive materials with compressive strength not exceeding 200MPa, such as coal, gypsum, and limestone.
Double Roll Crusher
3. Double Roll Crusher
- Working Principle: Two counter-rotating rollers squeeze the material, crushing it through pressure and shear force.
- Core Advantages: Less over-crushing, uniform product particle size, low dust, low noise, especially suitable for sites with strict dust control requirements.
- Applicable Materials: Brittle materials with medium hardness or below, such as coal, coke, and shale.

4. Compound Sand Making Machine
- Working Principle: Combines the principles of hammer crushing and impact crushing, representing an optimized combination of vertical shaft hammer crushing and impact plates.
- Core Advantages: Controls output particle size without the need for screens, is less prone to clogging, and has stronger adaptability to materials with higher moisture content.
- Applicable Materials: Various medium and low hardness ores and cement clinker, especially suitable for materials containing a certain amount of moisture.
How to Choose the Best Model? A 20-Year Expert Decision Guide
Choosing a sand making machine is not simply a matter of price comparison, but a systematic engineering process based on multiple technical parameters and production goals. We recommend following this decision path:
1. Clarify Raw Material Properties (Primary Factor)
- Hardness and Abrasiveness: For high hardness and high abrasiveness materials (such as granite, basalt), impact crushers are preferred; a wider range of options is available for medium and low hardness materials.
- Feed Particle Size and Moisture Content: Large feed sizes require consideration of upstream crushing; for high moisture content materials, compound or hammer crushers are better choices.
2. Define Product Requirements
- Finished Sand Particle Shape and Grading: If strict requirements exist for particle shape (e.g., for high-grade concrete), impact crushers are the preferred choice.
- Target Output: Match the equipment's processing capacity to your hourly/daily output requirements.
3. Evaluate Operating Costs
- Energy Consumption: Impact crushers and roller crushers generally have lower energy consumption.
- Wear Part Lifespan and Maintenance Costs: Calculate the wear rate and replacement costs of wear parts such as hammer heads, throwing heads, and liner plates. High-quality alloy wear parts can significantly reduce per-ton costs.
4. Consider Site and Environmental Factors
- Equipment Size and Layout: When space is limited, compact vertical shaft crushers have an advantage.
- Dust and Noise Control: Roller crushers and impact crushers with enclosed structures offer better environmental performance.
5. Weigh Investment Budget
- Balance initial investment with long-term operating costs while meeting core process requirements. Sometimes a slightly higher initial investment (such as choosing a more durable model) can lead to a lower total cost per ton of sand.
Success Story Sharing: Creating Value for Our Customers
Case Study 1: A Large Granite Sand Making Project in East China
- Challenge: High raw material hardness (Mohs hardness 7), requiring cubic-shaped finished sand particles, grading to meet the Class II medium sand standard, and a production capacity of 200 tons/hour.
- Solution: Recommended our high-performance VSI impact crusher, equipped with an intelligent control system to adjust the fineness modulus.
- Results: Excellent finished sand particle shape, with a needle-like and flaky content of less than 8%, fully meeting the high-standard requirements for commercial concrete sand. The service life of the core wear parts of the equipment exceeded 300 hours, and the customer's return on investment cycle was significantly shortened.
Case Study 2: A Limestone Comprehensive Utilization Project in Southeast Asia
- Challenge: Fluctuating raw material moisture content, limited investment budget, and the need for multi-purpose equipment.
- Solution: Adopted a heavy-duty composite sand making machine, whose screenless design effectively avoided clogging problems.
- Results: The production line ran stably, without clogging even during the rainy season when the raw material moisture content was high. The overall production cost was 15% lower than similar projects in the area.
Our Recommended Equipment
Based on a complete production line perspective, sand making machines need to work in conjunction with upstream crushing equipment (jaw crushers, cone crushers) and downstream screening and sand washing equipment. We can provide complete solution design and equipment supply for primary crushing, secondary and fine crushing, sand making and shaping, screening and washing, ensuring smooth operation and maximum efficiency of the entire line.
Frequently Asked Questions (FAQ)
Q1: Which sand making machine is better, the impact crusher or the roller crusher?
A: Better depends on the criteria. If you are pursuing optimal particle shape and grading (for high-value concrete), the impact crusher (VSI) is usually better. If you focus on low dust and low over-crushing rate (for asphalt concrete, etc.), the roller crusher performs well. The key is your product positioning.
Q2: What are the common reasons why the equipment capacity does not reach the nominal output?
A: The reasons could be multifaceted: ① The actual properties of the raw materials (such as hardness and moisture content) do not match the design assumptions; ② Uneven or discontinuous feeding; ③ The discharge port setting or wear of wear parts exceeds expectations; ④ Insufficient capacity of supporting equipment (such as feeders and conveyors) creates a bottleneck. Professional pre-sales testing and solution design can effectively avoid this problem.
Q3: How to effectively reduce the cost of wear parts consumption in sand making production?
A: We recommend a three-pronged approach: ① Correct equipment selection to avoid excessive wear caused by undersized equipment; ② Use high-quality alloy wear parts (such as high-chromium alloy), which typically have a lifespan 2-3 times longer than ordinary materials; ③ Optimize process parameters, such as reasonable rotor linear speed and feeding method.
