Whirlston heavy-duty hydraulic compost windrow turner covers wide ranges of turning capacities from 1600-3600m3/h. Our large capacity compost 
turner 40 series and 50 series are ideally suitable to turning soil or other materials in the fertilizer fermentation, gardening, landscaping as well as the maintenance of municipal parks.It features straddling on a windrow and starting turners drive through the windrow at a slow rate of forward movement. Because of the compact design, powerful engine and heavy duty, it is always the favorite for medium and large size composting plants.
Large Capacity Windrow Turner Convincing Features
1.Reasonable structure
—Self-propelled, no tractor necessary-optimal utilization of space available.
–Compact design;robust rubber undercarriage;heavy duty.
–Mature control technology making it very flexible and easy to handle.
–Exceptional mixing and crushing performance.
2.Efficient,cost effective solutions to compost fermentation.
3.Balanced power,low energy consumption,lower bio-organic fertilizer cost.
4.Affordable,low investment cost for medium or large fertilizer plants.
5.More suitable to manure fermentation fertilizer requirements,evenly mixing manure materials and bacterial preparation.
Large Model Compost Turner Structure
The heavy-duty compost turner is of innovative design.It is eqipped with crawler track unit, tractor model with an operator cabin,a steel drum with strong paddles which can turn rapidly for work. The paddles rotate to blend,crush and move compost windrow.It is more fit to manure fertilizer fermentation.
Compost Turner Role in Bio-organic Fertilizer Fermentation
Bio-organic fertilizer production can be divided into two phases:accelerated fermentation and maturing stage.In the first phase,the solutable organics turn some organics to inorganics by oxidation and release energy so that it can offer energy for micro-organism activities, therefore, organism can normally grow and reproduce and creat high temperature, which is called thermophilic waterlogged compost. During this stage,compost should accumulate enough oxygen that microorganism needs, that’s why we need compost turners to turn, loose and ventilate compost windrow to introduce oxygen. As compost turner moves through the windrow, oxygen is injected by paddle rotating, and waste 
gases produced by bacterial decomposition are vented. The oxygen feeds the aerobic bacteria, speeds composting process and eusures good quality fertilizer.
Self-propelled compost turner VS lane turner
⊙Compost turning creates an easy but nutrient environment for manure fermentation. The manure compost deodorizes in 3-5 hours, heat up to 50℃ in 16 hours, and keep the fermentation temperature at 60-70℃ for 3-4 days, thus fertilizer can be formed in 7-10 days. The micro-bacteria content is no less than 30 billion per gram. Self-propelled compost turner speeds up fertilizer production,besides, it prevents creating noxious and malodorous gas.The whole plant is benefit to environment and qualified bio-organic fertilizer.
⊙Aerobic fermentation is comparatively progressive fermentation method. Our self-propelled compost turner is designed based on the aerobic fermentation principle, and offers the zymocyte ideal space to grow. While lane turner will keep the compost windrow in anaerobic condition,which is not good to zymocyte growing, and sequentially influences fertilizer quality and production cycle.
