Ring Die vs Flat Die Pellet Machine Which is Better

In the field of feed processing and biomass energy production, pellet machine is the core main equipment, which can press powdery and finely divided raw materials into cylindrical pellets with compact structure, convenient transportation and higher utilization rate. Currently, the mainstream pellet machines on the market are divided into two types, namely ring mold pellet machines and flat mold pellet machines.

Many feed processing plants, breeding enterprises, biomass production businesses will face the same core problem when selecting equipment: which is better? In fact, there is no absolute difference between the two devices, only the difference between the adaptation scenarios. The ring mold equipment mainly focuses on large-scale, industrialized and efficient production, stable particle quality and outstanding productivity advantages; the flat mold equipment focuses on lightweight and miniaturized production, with high cost performance, flexible operation and wide adaptability.

This article will comprehensively analyze the two particle machines to help all kinds of production users accurately select the appropriate particle processing equipment in combination with their own production scale, raw material type and budget cost, so as to maximize production efficiency and control production costs.

What is a ring mold particle machine?

Ring die granulator definition: ring die granulator is also often referred to as ring die granulator, is an industrial dedicated large-scale particle pressing equipment, the core function is to powder, granular biomass raw materials, feed raw materials and all kinds of agricultural and sideline processing materials, through high-pressure extrusion process, processed into high density, forming regular, stable cylindrical particles. This equipment is widely used in industrial scenarios such as large-scale livestock and poultry feed production, biomass fuel pellet processing, and crop straw resource utilization. It is the core production equipment for large and medium-sized feed factories and biomass processing factories. Compared with traditional particle equipment, ring mold particle machine has stronger industrial adaptability and can meet the continuous production requirements for long time and uninterrupted.

Working principle of ring die pellet machine:The core molding part of ring die pellet machine is hollow ring metal mold with uniform molding holes. The equipment relies on 2 to 3 groups of pressure rollers inside the fuselage to cooperate with the rotating ring die to form a stable high pressure pressing system. Before production, the raw materials need to be crushed and dried, and the moisture content is adjusted to 10%-15%. The feed raw materials can be matched with steam conditioning to optimize the molding effect. The pretreated raw materials are sent into the ring mold, and the natural bonding components such as lignin and starch in the raw materials are activated through high pressure extrusion and friction at high temperature by pressing rollers to complete solidification molding. After the molded material passes through the mold hole, it is cut into cylindrical particles with uniform specifications by the cutter of the machine body, and the granulation operation is completed. The equipment is divided into horizontal and vertical two models, horizontal for large-scale feed production line, vertical for biomass sawdust pellet production, two models support all-weather continuous industrial operation.

What is a flat mold particle machine?

Two equipment whose feed pellet finished product quality is better?

In the feed pellet production scenario, the finished product quality of the two equipment has its own advantages and disadvantages, and there is no absolute good or bad, and the core depends on the production scale, feed category and use scenario. Large-scale standardized feed production preferred ring die pellet machine, small customized, high-fiber feed production flat die pellet machine has more advantages.

Ring-mold pellet machine finished product quality advantage scene

In the commercial and large-scale livestock feed production, the finished product quality of the ring mold pellet machine is fully dominant. The uniform high-pressure pressing process of the equipment can make the feed particles have higher density, stronger hardness, more stable structure, excellent particle molding consistency, high whole particle rate and extremely low dust and debris ratio. This kind of high-quality particles are not easy to break and mildew during long-distance transportation and storage, and can retain feed nutrients to the greatest extent and reduce nutrient loss.

At the same time, the ring mold equipment can be perfectly matched with steam conditioning system, which can realize full ripening of feed raw materials, improve feed palatability and digestion and absorption rate of livestock and poultry, especially suitable for concentrated feed and concentrated feed production of pigs, chickens, ducks and other livestock and poultry. Standardized particle size, can also be perfectly adapted to automatic breeding feeding equipment, to avoid uneven particle size caused by feeding stuck, uneven intake problems, is the first choice for commercial high-quality feed production.

Flat die pellet machine finished product quality advantage scene

The quality advantage of the flat-die pelletizer is concentrated in small farming scenarios and high-fiber roughage production. For hay powder, straw powder and other coarse fiber, light coarse feed, ring mold equipment is prone to uneven feeding, insufficient pressing problems, and flat mold equipment vertical pressing structure, can better grasp light coarse fiber raw materials, molding effect is more stable. Although the finished product particle density and uniformity are slightly lower than the ring mold products, it can fully meet the feeding needs of family breeding and small farms.

The cost-effective advantage far exceeds that of ring mold equipment.

Which of the two devices is more cost-effective?

The core cost performance of the equipment depends on the production volume. Small-scale intermittent production flat-mold pellet machine has higher cost performance, and medium-and large-scale continuous production ring-mold pellet machine has better long-term cost performance. Users need to comprehensively judge in combination with their own production capacity requirements and operation cycle.

Flat mold particle machine high cost performance applicable scene

The core advantages of the flat-die pellet machine are low short-term investment, low operation and maintenance cost and no waste of resources. In the scenario of hourly output less than 1000 kg, intermittent production and seasonal production, the cost performance is full. There is almost no high cost for equipment procurement, installation and commissioning in the early stage, and the vulnerable parts are cheap and convenient to maintain. Small-scale production does not need to consume a large amount of power resources, and there will be no energy consumption and waste problem of large-scale equipment running at low load. For small users whose monthly output is less than 15 tons, the flat mold equipment can meet all production needs with extremely low investment, no idle waste, no cost redundancy, and a high short-term return on investment.

Ring mold particle machine high cost performance applicable scenarios

The cost-effective advantage of the ring mold particle machine is reflected in the long-term large-scale operation. Although the equipment investment is high in the early stage, under the working conditions of more than 1 ton per hour and all-weather continuous production, the energy consumption per ton of equipment is lower, the production efficiency is higher, the replacement cycle of parts is longer, and the downtime loss is less. After long-term operation, the comprehensive production cost per ton of particles is much lower than that of flat-mold equipment, and the finished product quality is higher and the market premium is better. For commercial production lines with monthly output of more than 20 tons, the ring mold equipment can quickly recover the initial investment through efficient mass production, and the long-term profit advantage and cost advantage are very prominent.

Cost Comparison Core Summary

Short-term, small, scattered production, flat mold particle machine lower cost, higher cost performance; long-term, stable, large-scale commercial production, ring mold particle machine comprehensive operation cost is lower, profitability is stronger. For small-scale projects with an annual production capacity of less than 500 tons, flat mold equipment is the best choice; for large-scale projects with an annual production capacity of more than 2000 tons, ring mold equipment can achieve a profit increase of 15%-20%, and the cost performance advantage is significant.

How to choose the right particle machine equipment?

Combined with the performance differences, advantages and cost-performance rules of the two equipment, combined with the production scale, raw material type, budget cost, long-term planning, to provide accurate selection solutions for different users, to help users avoid selection errors, to achieve accurate matching of equipment and production scenarios.

Preferential selection of flat die pellet machine

If your production scenario is family farming, small farms, start-up small workshops, the hourly output demand is less than 800 kg, the budget is limited, and the pursuit of low investment and fast production is preferred. If the raw materials for production are mostly coarse fiber straw, hay and miscellaneous materials with high moisture content, it is necessary to change the feed formula frequently, produce in small batches and in multiple categories, or the production site has no stable industrial power and the site space is narrow, and the flexibility and adaptability of the flat mold equipment can perfectly match the demand. At the same time, for the scenarios of seasonal production, intermittent operation and zero basic operators, the advantages of easy operation, easy operation and maintenance and no idle loss of flat mold equipment will be maximized.

The case of preferential selection of ring mode particle machine

If it is a large-scale feed processing plant, professional biomass production enterprise, commercial mass production project, the hourly output demand is higher than 1 ton, and it is necessary to continuously produce all day long. If the main commercial pellet sales, particle density, uniformity, finished product quality, packaging and transportation stability have strict standards, or raw materials after standardized pretreatment, mainly fine feed, hard biomass raw materials, ring mold equipment can produce high-quality finished products, improve product market competitiveness. In addition, there are long-term production planning, the pursuit of low long-term operating costs, users planning to build fully automatic production lines, and the intelligent, efficient and stable advantages of environmental mold equipment, which can provide continuous guarantee for large-scale production.

Additional Selection Considerations

In addition to core production needs, site conditions, technical reserves, and future expansion plans are also important basis for selection. Small site, no professional equipment operation and maintenance personnel, priority flat mold equipment; industrial plant, professional technical team, plan to expand production capacity later, priority ring mold equipment. From the perspective of full life cycle cost, flat mold equipment wins in short-term low-cost investment, and ring mold equipment wins in long-term efficient profitability. From the point of view of finished product adaptation, coarse feed and miscellaneous feed production choose flat mold, concentrate feed and commercial standardized pellet production choose ring mold.

The most practical reference standards for selection: with a monthly output of less than 15 tons, for small groups of self-use production, select a flat-die pellet machine; with a monthly output of more than 20 tons, for commercial mass production, select a ring-die pellet machine, which is simple and accurate for most production scenarios.

As the two mainstream granulation equipment, ring mold granulator and flat mold granulator have clear performance positioning and adaptation scenarios, and there is no absolute advantage or disadvantage, only the difference between adaptation and non-adaptation. With the advantages of low cost, high flexibility and easy operation, the flat-mold pellet machine is firmly rooted in small and medium-sized, fragmented and self-use production scenarios, and is an inclusive equipment for small and micro enterprises and individual farmers; the ring-mold pellet machine has become the core equipment for industrialization, commercialization and large-scale mass production with the advantages of high production capacity, high quality, high stability and low long-term energy consumption.

When selecting equipment, users do not need to blindly pursue high-end equipment, nor do they need to be greedy for low prices. The core combines its own production scale, raw material characteristics, use scenarios, budget and long-term development planning to accurately match. Small self-use, flexible production selection of flat mold, efficient mass production, commercial profit selection of ring mold, only to adapt to their own production needs of equipment, in order to maximize production efficiency, control production costs, to maximize production benefits. In the future, with the refined development of pellet processing industry, the two types of equipment will continue to be iteratively upgraded to adapt to more subdivided production scenarios and provide better equipment support for feed processing and biomass resource utilization industries.
