Pellet Machine for Horse Stable Bedding 0.5-5t/h | Supplier Guide
News 2026-07-06
Product Definition
A pellet machine for horse stable bedding is a ring die compaction system that converts straw, hay, and wood shavings into soft, absorbent pellets specifically designed for equine bedding applications. The machine produces low-dust, high-absorbency bedding pellets that provide superior comfort and respiratory health benefits for horses compared to traditional loose bedding materials.

Manufacturing Process – Engineering Workflow
Step 1 – Straw/Hay Collection & Screening
Straw or hay baled from fields. Remove contaminants (stones, metal) using destoner and magnetic separator. Screen out fines and dust.
Step 2 – Grinding & Particle Size Reduction
Hammer mill reduces straw to ≤4–6mm particle size. Uniform grind ensures consistent pellet formation and absorbency.
Step 3 – Drying & Moisture Control
Straw and hay typically have 12%–20% moisture. Dryer or blending adjusts to 14%–16% for optimal pelletising.
Step 4 – Pelletising (Core Forming Process)
Main motor drives ring die rotation at 4–5 m/s peripheral speed. Rollers compress fibrous material through die holes. Larger holes (8–12mm) and lower density produce softer pellets for horse comfort.
Step 5 – Counterflow Cooling
Pellets exit at 80–95°C. Cooling reduces temperature to ambient +5°C and moisture to ≤12% for storage stability.
Step 6 – Screening & Bagging
Gentle screening removes fines and weak pellets. Low-dust bedding pellets bagged for sale to equine facilities.

Differentiation (Shandong Changsheng Machinery):
Our horse bedding pellet machines produce pellets with optimised properties for equine applications – low density (400–600 kg/m³) for softness, large diameter (8–12mm) for absorbency, and low dust (PDI ≥92%) for respiratory health. The ring die design with gentle compression ensures pellet integrity while maintaining pellet softness. Complete systems including hammer mill, dryer, and cooler available.
Application Scenarios by Buyer Role
Distributors / Importers
Focus on machine suitability for regional bedding materials. Require pellet quality data for customer marketing.
EPC Contractors
Integrating bedding pellet lines – collection, grinding, drying, pelletising, packaging. Need system design support.
Engineering Consultants / Technical Advisors
Evaluate horse bedding production viability. Require absorbency and dust testing for product quality verification.
End-user Production Facilities
Horse stables, equestrian centres, and bedding manufacturers. Demand low-dust, high-absorbency pellets for equine health.
Core Pain Points & Engineering Solutions
Pain Point 1 – Dust causing respiratory issues in horses
Root cause: Loose straw and shavings generate dust – respiratory problems for horses.
Solution: Low-dust pellets with PDI ≥92% – minimal fines. Dust extraction during processing.
Pain Point 2 – Low absorbency of traditional bedding
Root cause: Straw bales have low absorbency – frequent changing required.
Solution: Pellets absorb 2–3× their weight in moisture – longer lasting, reduced labour.
Pain Point 3 – High bedding cost
Root cause: Commercial shavings and paper pellets are expensive – $200–$400 per tonne.
Solution: On-farm production from straw and hay – cost $80–$120 per tonne. Significant savings.
Pain Point 4 – Inconsistent product quality
Root cause: Variable feedstock quality – seasonal changes in straw/hay.
Solution: Moisture control and blending. Quality testing for absorbency and dust. Consistent product specifications.
Critical Risk Warnings & Mitigation Measures
Risk 1 – Mould in stored straw causing respiratory issues
Mitigation: Test straw for mould. Store in dry conditions. Dryer to reduce moisture before storage.
Risk 2 – Dust affecting horse respiratory health
Mitigation: Low-dust pellets (≥92% PDI). Dust extraction at transfer points. Inform customers of low-dust benefits.
Risk 3 – Foreign objects (stones, metal) in pellets
Mitigation: Destoner and magnetic separator. Regular screen inspection.
Procurement Selection Guide – 7 Executable Steps
Step 1 – Analyse available bedding materials
Identify straw, hay, wood shavings, or other residues. Quantify annual requirement. Test moisture and dust content.
Step 2 – Determine required capacity
Calculate bedding requirement or target production volume. Select model with 20% capacity margin.
Step 3 – Select pellet diameter
8–10mm for general stables. 10–12mm for larger bedding applications. Larger pellets have better absorbency.
Step 4 – Specify moisture control system
Dryer if feedstock moisture exceeds 18%. Blending for seasonal moisture variation.
Step 5 – Verify power supply and electrical capacity
Motor 55–160 kW. Hammer mill and dryer additional. Soft-start for reduced starting current.
Step 6 – Plan for low-dust handling
Gentle conveying. Dust extraction. Low-dust packaging (bags or bulk).
Step 7 – Establish quality control
Moisture testing. Absorbency testing. Dust testing. Product specifications.
Engineering Case Study – Equestrian Centre in United Kingdom
Project Background
A 50-horse equestrian centre in the UK uses 100 tonnes of bedding annually. Wood shavings cost £180/tonne – annual cost £18,000.
Initial Problem
Bedding cost was a major operating expense. On-farm straw was available but processing to pellets would save costs and improve stable conditions.
Root Cause Analysis
No pelletising equipment. Straw bales were dusty and less absorbent – horses had respiratory issues. Processing straw to produce bedding pellets would improve horse health and reduce costs.
Solution Implemented
Installed Shandong Changsheng bedding pellet mill (0.5 t/h capacity). Processed 150 tonnes of straw annually to produce 120 tonnes of bedding pellets.
Final Data Results (12-month average)
| Metric | Before (Wood Shavings) | After (On-Farm Straw Pellets) |
|---|---|---|
| Bedding cost per tonne | £180 | £85 |
| Annual bedding cost | £18,000 | £8,500 |
| Dust level in stables | Moderate | Very Low |
| Absorbency rating | Moderate | High |
| Respiratory issues (horses) | 3/year | 0/year |
| Payback period | N/A | 18 months |

3. What is the typical capacity range?
0.5 – 5.0 t/h depending on model and feedstock.
4. What is the optimal pellet size for horse bedding?
8 – 12mm diameter. Larger pellets provide better absorbency.

Yes – low-dust pellets reduce respiratory issues. Fibre content is digestible if ingested.
6. What is the absorbency of bedding pellets?
High – pellets absorb 2–3× their weight in moisture.
7. Are bedding pellets dust-free?
Low dust – PDI ≥92%. Minimal respiratory irritation.
8. What is the cost of producing bedding pellets?
£70 – £100 per tonne depending on feedstock and energy costs.
9. Is drying required for straw?
If moisture exceeds 18% – yes. Straw from dry harvest may not require drying.
