FAQ:
 

Why is it important to pelletize animal and poultry feeds?

  • The production of high grade feed pellets from low-grade feed components to maximize value adding.

  • Better growth at a lower feed cost.

  • Minimized wastage.

  • Cheaper transport, handling and storage of feed.

  • Elimination of respiratory problems normally associated with dust in feed.

  • More palatable feed pellets improve feed conversion ratio.

  • Improves growth to lower feeding costs.

  • Selective feeding eliminated.

  • Minimize feed losses during storage.

Other applications of our pelleting machines:


Our pelleting machines can be used to process a wide variety of industrial waste, biomass and fertiliser products. Some of these products are extremely hard to pelletize and care should be taken to select the correct type of pelletor with a strong and rigid design.

Some of the advantages of biomass pelleting are:

  • Turns waste into usable and valuable products.

  • Improves calorific value due to compaction.

  • Environmental safer option when used as a substitute for certain fossil fuels.

  • Improves hygiene.

  • Better handling, storage and cheaper transport.

  • Convenient way to apply product in the field and improves application by machinery.

Information needed to advise plant design:

  • Size, throughput and scope of project (daily or monthly output).

  • Requirements in regards to different elements of feed mill including handling and storage of raw materials, milling requirements, batching and mixing systems, conditioning and pelleting, storage and packaging of finished product.

  • Development of infrastructure and structures in regards to the feed mill.

  • Type, quantity and characteristics of raw materials for pelletising and customer•s anticipated feed formulations in order to advise die selection and plant specification.

  • Existing machines and equipment that needs to be upgraded or incorporated into the new plant.

  • Degree of plant automation.

  • Requirements in regards to engineering services and project management.

What determines pellet mill capacity?


The capacity of a pellet machine is determined by various factors including:

  • Characteristics of compound:

  • The most important factor is the feed formulation.

  • The inclusion rate of light and fibrous materials like hay or roughage will lower output while more dense ingredients will increase output. Low density compounds
    (300 to 400kg/m3) requires more specific energy for compaction and binding into a pellet and will lower the output.

  • Average moisture content of compound (In general: moisture content < than 15% for successful pelleting).

  • Choice of binding agent, molasses and fat addition (oil content) where applicable.
     

  • Characteristics of system:

  • Fineness and texture of raw ingredients.

  • Proper mixing of raw ingredients.

  • Condition and choice of die (hole size and pressure ratio - ratio of rim thickness to hole size, type and condition of countersink).

  • Correct quality and quantity of steam (degree of conditioning).

  • In feed to pelletor (even and uninterrupted).

  • Efficient pelletor (large ratio of roll to die diameter, effective transmission).

What is important when designing a pelleting system?


Planning and design is of utmost importance and requires years of experience to avoid costly mistakes and project mismanagement.

Plants normally operate in cycles by blending and mixing consecutive batches of one or two tons each. The required output is then accomplished by designing the unit to produce a certain quantity of batches per hour. The quantity of batches and raw ingredients will determine the sophistication and design of the system.

A good design will ensure that all elements in the feed mill are well balanced to produce the required amount of batches without blockages or interruptions.

Raw and finished products can be handled in bulk but bagging is required where the end user cannot handle bulk feeds.

Our engineers utilize the latest CAD design software and 3 D drawings to supply a full set of drawings before the start of any manufacturing. We work closely together with our clients to make sure that their requirements and all plant specifications are fully met.

 

Feasibility studies:


Each project must be evaluated on its own merits to test economic viability.

Important variable cost factors are:

  • Energy cost.

  • Labour cost.

  • Running or maintenance cost.

Important fixed cost are:

  • Interest cost

  • Capital cost
