颗粒设备:类型和主要生产商 Pelleting equipment: types and main producers

发布日期:2016-5-17 13:38:43  浏览量:

随着环境问题日益严峻,如今可再生能源变得越来越受大众欢迎。在这种情况下,世界各地正在使用木质颗粒,这种相对较新的燃料。许多企业家开展自己的颗粒生产业务。因此,他们需要购买适合的设备。

Nowadays renewable energy sources become more and more popular, as environmental issue arises. In this case, wood pellets, relatively new kind of fuel, are being used all over the world. Therefore, a number of entrepreneurs are starting their own pellet producing business. Consequently, they need to purchase appropriate equipment.

颗粒生产阶段

Stages of pellet making

一般情况下,需要用一条完整的生产线来生产颗粒。颗粒生产的技术包括以下步骤:破碎、筛分、干燥、制粒、冷却和包装。

As a rule, a complete pellet line is used in order to produce pellets. The technology of pellet making consists of following steps: crushing, screening, drying, pelletizing, cooling and packing.

 

因此,需要各种不同的设备来完成这些步骤。这些设备包括剥皮机或削片机、锤式粉碎机、烘干机、颗粒机(压块机)、冷却和包装机。

So, different kinds of equipment are required to accomplish them. This equipment includes debarker or chipper, hammer mill, dryer, pellet mill (press), cooling and packing machines.

Units of pelleting equipment

剥树皮机

应用于分离树皮。通过这种方式制备原木用于进一步加工。有这种设备的2种类型:单辊和双辊剥树皮机。第二种的生产效率更高:双辊剥树皮机每天能够处理70-100吨原木。

Debarking machine is applied in order to peel and debark logs of wood. In this way, raw wood is being prepared for the further processing. There are two models of this kind of equipment: single roller and double roller debarking machine. The productiveness of the second one is higher: double roller debarking machine is able to process 70-100 tonnes of wood logs per day.

锤式粉碎机

在造粒的过程中应用于粉碎木片。它能够粉碎不同尺寸的原木。虽然锤式粉碎机能够处理小树枝和木片,但是它主要是用来粉碎体积大的。用锤式粉碎机击打原料,直到它是小到足以进行筛分。

Hammer mill is applied in the process of pelleting in order to pulp wood chips. It makes it possible to turn logs of different size into smaller ones. Though hammer mill is able to process small branches and chips, it is mostly use to pulp big ones. In the hammer mill, material is being struck until it is small enough to be screened.

烘干机

因为新鲜原木含有丰富的水分,所以加工前应对它们进行干燥。同时,水分太容易蒸发,这使处理的材料缩水、发霉或出现其他问题。因此,用这种材料制成的颗粒质量不好。这就是为什么需要烘干机为进一步造粒准备材料。通常,适当的水分含量应为8-15%。

As fresh wood logs contain significant amount of moisture, they should be dried before processing. At the same time, moister evaporates too easily, which makes handled material shrunk, mildewed or spoiled in any other way. Consequently, pellets, made of such material, are of low quality. That is why drying machine is required to prepare material for the further stages of pelletizing process. As a rule, an appropriate moisture content should equate 8-15 per cent.

 

有两种类型的烘干机:滚筒式木屑烘干机和导管式木屑烘干机。第一种是普通类型,被广泛应用于颗粒厂。它的容量从2.5-36吨不等。同时,导管式木屑烘干机的容量不是那么高;然而,这种类型的烘干机的优点是低能耗和低成本。

There two types of dryers: rotary sawdust (drum) drying machine and pipe sawdust dryer. The first one is a common type and is widely used in pellet plants. Its capacity varies from 2.5 to 36 tonnes. At the same time, the capacity of pipe sawdust dryer is not so high; however, the advantages of this type of dryer are low energy consumption and low cost.

颗粒机

应用于颗粒生产的主要阶段。用先前处理好的原料制成颗粒。颗粒机操作的原理是与粉碎机相反。粉碎机用来粉碎原木,而颗粒机被应用于生产更大、均匀的团块。

Pellet mills, also known as pellet presses are applied at the main stage of pellet production. They are used to create pellets of previously processed raw material. The principle of pellet mill operation is opposite to hammer mill one. While hammer mill is used to pulp wood logs, pellet mill is applied to create larger, homogeneous mass.


有各式各样的颗粒机,可分为两大类:大型和小型颗粒机。与此同时,大型颗粒机主要有两种,包括平模和环模。一般情况下,平模颗粒机用于生产更高质量的颗粒。

There are many types of pellet mills, which can be divided into two main groups: large-scale and small-scale mills. At the same time, there two main types of large-scale mills, which include flat die and ring die mills. As a rule, flat die mills are applied to produce pellets of higher quality.

冷却机

在颗粒生产的最后阶段,要运用到冷却机。使用这种机器能够使颗粒温度从80-90℃降到室内温度。它还能使水分含量从17%-18%降到12%-13%。

At the last stage of pellet production, cooling machine is applied. The use of this machine gives an opportunity to reduce the temperature of pellets from 80-90 degrees to the ambient temperature. It also reduces the content of moisture from 17-18 to 12-13 per cent.

主要的颗粒设备生产商

Main producers of pelleting equipment

目前,乌克兰颗粒设备市场在不断增长。供应商能够为企业提供相应的设备。但是,其国内市场的主要特点是,并没有完整的颗粒生产线。为单独购买装置提供了机会。在乌克兰出售的一整条生产线都是通过进口的。

Nowadays the Ukrainian market of pelleting equipment is growing. A wide range of suppliers provides entrepreneurs with appropriate equipment. However, the main characteristic of domestic market is that it does not provide complete pellet lines. There is an opportunity to purchase separate units. Complete lines, which are sold in Ukraine, are imported.


在这种情况下,有必要提及那些生产颗粒设备的国家。首先,是加拿大。它是第一个同时生产的颗粒机和颗粒的国家。除此之外,也有一些国家生产同样的设备。他们全部拥有广阔的森林面积。

In this case, it is necessary to mention those countries, which are producing pelleting equipment. First of all, it is Canada. This country was the first to produce both pelleting equipment and pellets. Beyond that, there are a number of countries, which also produce the same equipment. All of them possess significant forest areas.


这些国家包括美国、俄罗斯、中国、瑞典和德国。也有其他一些国家,专门生产价格低廉设备的,例如波兰和立陶宛。所有这些国家在全球市场上出售完整的颗粒生产线以及单独的颗粒设备。

This list includes USA, Russia, China, Sweden, and Germany. There are also several countries, which are producing cheaper equipment. Among them are Poland and Lithuania, for instance. All these countries provide world market with both complete pellet lines and separate units of pelleting equipment.

 

总之,颗粒市场正在迅速增长。这就是为什么许多企业家开展自己的颗粒生产业务。在这种情况下,特定设计的设备是必需的。在颗粒生产的不同阶段应用特定的设备。目前,这些国家如美国、加拿大、德国、瑞典、中国、俄罗斯和立陶宛仍然是颗粒设备的主要生产商。

In summary, pellet market is rapidly growing. That is why a wide range of entrepreneurs starts their own pellet production. In this case, specially designed equipment is required. It consists of several units applied at the different stages of pellet production. At present, such countries as USA, Canada, Germany, Sweden, China, Russia and Lithuania remain the main producers of pelleting equipment.
