The quality of the product is also a significant factor in the selection of a granulating machine. In the event that the product quality requirements are exacting, for example in regard to the shape, size, density and other rigorous specifications for the particles, it is necessary to choose a machine with a high level of stability and precision. Furthermore, it is essential to consider whether the production process of the pelletising machine is capable of meeting the quality requirements of the product. This may include the ability to achieve uniform granulation, which can help to avoid issues such as granule crushing.
Examine the performance parameters of the pelleting machine
Pelletising machine capacity
Capacity is a significant indicator of the efficiency of production in a pelletiser machine. In general, an increase in the capacity of a granulating machine will result in a greater number of products being produced per unit of time, thereby enhancing the overall production efficiency of the pellet plant. In selecting a pelletising machine, it is essential to ascertain the requisite capacity in accordance with the scale of production and market demand, and to select the most suitable pelletiser machine.
Power of granulating machine
The power of a pelletising machine has a direct impact on its energy consumption and running costs, which are influenced by a number of factors. It is typically the case that an increase in the power of a pelletising machine will result in a corresponding rise in energy consumption. Consequently, when selecting a granulating machine, it is essential to evaluate the correlation between production capacity and power, and opt for a granulating machine that can fulfil the production requirements while minimising energy consumption.
Particle size range
The capacity of pelletising machines to produce pellets of varying sizes is dependent on the specific machine in question. In selecting a pelletising machine, it is essential to ascertain the requisite range of pellet sizes in accordance with the specifications of the intended product and to choose a machine that is capable of meeting these specifications. Additionally, it is crucial to ascertain whether the pelletising machine is capable of maintaining precise control over the pellet size, in order to guarantee the quality of the product remains consistent.
Stability and reliability
The stability and reliability of the granulating machine are of paramount importance in ensuring the smooth functioning of the production process. The stability of the pelletising machine is a key factor in ensuring its long-term reliability and reducing the probability of failure. The reliability of the pelletising machine is such that it is able to operate normally in harsh working environments, thereby ensuring the continuity of production. In selecting a pelletising machine, it is possible to ascertain the manufacturer’s qualification certificate, user evaluation and other pertinent information in order to gain an understanding of the machine’s stability and reliability.
Understanding the working principle and characteristics of granulators
Working principle of the pelleting machine
Different types of pelletising machines have different working principles. For example, extruder granulator is to make the material into granules by extruding; drum granulator is to make the material into granules by rotating; spray granulator is to make the material into granules by spraying. Understanding the working principle of granulating machine can help us better understand its performance characteristics and scope of application, so as to choose the right granulating machine.
Features of the granulator
Pellet feed, biomass pellets and organic fertiliser pellets are suitable for different types of granulators due to different raw materials and applications and have their own characteristics.
Pellet feed is usually suitable for ring die pellet machine. Ring die pellet machine has the characteristics of high production efficiency, good pellet forming and moderate hardness. When it works, through the extrusion effect of ring die and pressure roller, it combines all kinds of feed materials closely into granules. The shape of pellet feed is regular and uniform in size, which is easy for animals to feed and reduce waste. Meanwhile, the ring die pellet machine can adjust the formula according to the nutritional requirements of different animals and produce many types of pellet feed. In addition, the machine is relatively simple to operate and has low maintenance cost.
Biomass pellets are suitable for both flat die pellet mill and ring die pellet mill. The flat die pellet machine is simple, inexpensive and easy to operate, which is suitable for small biomass pellet manufacturers. It compresses biomass raw materials into pellets through the action of flat die and pressure roller. Biomass pellets have high density, high combustion value, easy to store and transport. Ring die pellet machine has higher capacity in biomass pellet production, regular shape of pellets and stable quality. As a kind of clean and renewable energy, biomass pellets can be widely used in home heating, industrial boilers and other fields.
Organic fertiliser pellets are generally suitable for disc granulators and drum granulators. The disc granulator has the features of simple operation and high rate of ball formation. It uses the rotation of the disc to make organic fertiliser raw materials gradually form granules under the action of friction and gravity. Organic fertiliser granules help to increase soil fertility, improve soil structure and promote crop growth. Drum granulator, on the other hand, produces granules with high strength and smooth surface. Both granulators can adapt to the diversity of organic fertiliser raw materials and convert various organic wastes into high-quality organic fertiliser granules.
Consideration of quality and price of granulators
Quality of granulator
The quality of granulator is directly related to its service life and production efficiency. When choosing a granulator, you should choose a product with reliable quality and stable performance. You can find out the quality of the product by checking the production process, quality control system and after-sales service of the granulator manufacturer. Meanwhile, you can also refer to the use evaluation of other users to understand the actual use effect of the granulator.
Prices of pelletising machines
Price is one of the factors to consider when choosing a pelletiser. The price of pellet mills varies greatly from brand to brand and model to model. When choosing a pelletiser, you should choose a cost-effective product according to your budget and production requirements. Do not just look at the price and ignore the quality and performance of the product. At the same time, it is important to consider the subsequent maintenance and running costs of the pelletiser to ensure that the pelletiser you choose can deliver long-term economic benefits to the business.
Consider after-sales service
Installation and commissioning support
The installation and commissioning of the pellet mill is an important part of ensuring its normal operation. When selecting pellet mills, pellet mills should choose pellet mill manufacturers that can provide professional installation and commissioning services. Manufacturers should send professional technicians to carry out the installation and commissioning to ensure that the pellet mill can operate normally.
Technical training services
The technical level of the operator has a direct impact on the use of the pelletiser and production efficiency. When choosing a pelletising machine, choose a manufacturer that can provide training services. The manufacturer should send professional technicians to train the operators so that they can master the operation method and maintenance skills of the pelletising machine.
