If you build asphalt in Indonesia, you know filler quality matters. Filler in the 0–10 mm range improves density, workability, and asphalt mix stability. Yet not every mobile stone crusher plant can deliver consistent 0–10 mm limestone. In this post I explain which mobile crusher types work best, how to configure them, and what to check on-site. I write from the practical perspective of contractors and site managers. I also explain how AIMIX can help with selection and commissioning at your project.

Why 0–10 mm Limestone Filler Is Critical

Limestone filler in the 0–10 mm fraction fills voids between larger aggregates. As a result, it improves compaction and reduces permeability. For asphalt plants, consistent particle size and low moisture are essential. If filler varies, your mix design suffers. Therefore choosing the right crushing and screening flow is the first step.

Next, let’s look at how crushers produce this size range and what to prioritize on-site.

Types Of Mobile Crushers Suitable For 0–10 mm Limestone

Not every mobile crusher produces fine filler directly. You must match equipment to the job. Below are the common options and when to use each.

1. Mobile Impact / Vertical Shaft Impact (VSI) Crushers

VSI crushers excel at making fine, cubical particles. For limestone filler, a mobile VSI delivers controlled fines and good particle shape. Use a VSI when you need high-quality sand and filler in one pass. Furthermore, VSI works well with secondary or tertiary stages after a primary jaw or impact crusher.

2. Mobile Cone Crushers (With Closed-Circuit Screening)

Cone crushers give good control over gradation in the 4–10 mm range. Pair a cone with a high-efficiency screen in closed-circuit mode. This setup returns oversized material for re-crushing and produces stable 0–10 mm output. Use cones when you want robust throughput and lower wear costs compared with VSI for harder stones.

3. Mobile Jaw Crushers + Mobile Sand Maker / VSI

For many sites, a two-line solution works best. First, a mobile jaw crushes the feed to a manageable size. Then a mobile sand maker or VSI shapes and reduces the material to 0–10 mm. This multi-stage flow increases control. It also lets you adjust production by changing screen meshes and rotor settings.

4. Mobile Impact Crushers (For Softer Limestone)

When limestone is relatively soft, a mobile impact crusher can produce fines economically. Impact models reduce material size quickly. However, the limestone crusher plant sometimes can produce flatter particles. If particle shape matters, follow the impact crusher with a VSI or additional screening.

In short, choose VSI for quality fines, cone crushers for steady gradation, and jaw+VSI for flexible multi-stage production.

Essential Configuration And Site Considerations

Choosing the crusher type is only part of the solution. You must set up the entire flow to meet asphalt plant specs. Below are the practical items to check and optimize.

Screening And Closed-Circuit Control

Install at least one vibrating screen after the crusher. Use a closed-circuit loop to return oversize material back to the crusher. This loop stabilizes the output and improves size consistency. Also, use a fine mesh (e.g., 0–10 mm decks) to capture the filler fraction precisely.

Feeding Size And Pre-Screening

Keep feed size within the crusher’s rated range. Oversized feed reduces crusher efficiency and creates variable fines. If necessary, add a scalping screen before the primary crusher to remove fines or clay. Pre-screening also reduces moisture and slimes that harm product quality.

Moisture Control And Stockpiling

Moisture affects screening efficiency and particle cohesion. Avoid crushing immediately after heavy rain. If you must work, use drying conveyors or rapid stockpile turnover. Store final filler in covered silos or well-drained stockpiles to protect gradation and prevent caking.

Quality Monitoring And Gradation Testing

Run sieve tests regularly. Check for compliance with the 0–10 mm spec. If the gradation shifts, adjust screen meshes, change rotor speed on VSI, or modify cone setting. Quick testing keeps your asphalt mixes consistent and saves on rework.

Typical Mobile Plant Layout For 0–10 mm Filler

For practical planning, here is a simple layout that works on most Indonesian sites:

• Primary mobile jaw crusher with scalping screen.
• Conveyor to a secondary crusher (cone or impact).
• Mobile VSI or sand maker where fine shaping is required.
• Vibrating screens with 0–10 mm deck. Use closed-circuit loops.
• Final conveyor to covered silo or dedicated stockpile area.

This flow provides flexibility. It also lets you scale up capacity by adding a second secondary line.

Choosing The Right Capacity And Mobility

Decide capacity based on daily asphalt production. For small asphalt plants, a mobile unit that produces 30–80 tph may suffice. For larger plants, choose configurations rated higher. Also, check transport restrictions for Indonesian roads. Mobile crushing plants for sale that fold onto trailers help shorten setup time and save logistics cost.

Final Thoughts And Call To Action

In summary, you can produce high-quality 0–10 mm limestone filler with the right mobile crusher combination. If you need clean, consistent filler, prefer a VSI or a cone-VSI flow with closed-circuit screening. Control feed, moisture, and screening. Test gradation often. Also, plan stockpiles and transport to protect the product.
