What Is A Pellet Mill?


 

Pellet Mill For Sale

Biomass pellet mill is a kind of equipment that compresses biomass raw materials into granular materials. Pellet mill is mainly used in chemical, agriculture, energy, pharmaceutical, environmental protection and other industries in the granulation process. This article will provide a comprehensive analysis of the working principle, advantageous features, applications, use and maintenance of the pellet mill.
 

Working Principle of Pellet Mill

Pellet mill is a device that extrudes loose materials (sawdust, wood chips, wood flour, fertiliser, etc.) into high-density particles at high pressure through mechanical pressure. The main parts of the pellet mill include pressure rollers, moulds, cutters, motors and so on. When producing pellets, the raw material is forced through the mould holes, rotated and pressed by the rollers. Cylindrical or spherical pellets are formed under high pressure. Eventually cut into the same standard length by the cutter. Finally solid pellets are formed. Pellet mill is suitable for granulation of different kinds of solid materials.

 

Main Functions and Advantages of Pellet Mill

High efficiency and energy saving: the pellet mill is designed with high efficiency and energy saving. It can produce high quality and uniform size biomass pellets in a short time. It greatly saves time and resources.

Improve raw material utilisation: pelleting can be a 15%-20% increase in biomass raw material consumption rate. The granule structure is easier to be absorbed by the material.

Adjustable particle size: The particle size of the pellet mill can be adjusted by adjusting the parameters of the pellet mill. By adjusting the parameters such as the pressure and speed of the wheel and roll. Different sizes of finished pellets can be produced, which can meet different customers' demands.

Wide range of application: 2-12mm pellets can be produced by changing different moulds. Adapt to different industry needs.

Convenient operation: the pellet mill is convenient to operate and easy to master. It can reduce the cost and difficulty of manual operation.

Intelligent control: adopting advanced control system and automation technology, it can realise automatic production and intelligent control.

 

Types of Pellet Mill

Flat Die Pellet Mill

is suitable for small and medium-sized production, commonly used in small farms or family-style use. Flat die pellet mill has the advantages of simple structure, low maintenance cost and 90% moulding rate.

Ring Die Pellet Mill

Suitable for industrial production and processing. It is commonly used in feed factory, fuel factory, biomass energy factory and so on. The forming rate of ring die pellet mill is up to 98% or more. But the mould structure is more complicated. The price of the equipment is higher.

Pellet Mill Application Fields

Pellet mill is widely used in metallurgy, medicine, food, chemical and other industries. In the pharmaceutical industry, pellet mill is mainly used to produce tablets, capsules and other drugs. In the food processing industry, the pellet mill is mainly used to produce various food additives, spices and other granular materials. In the chemical industry, it is mainly used to produce various fertilisers and pesticides and other granular materials. In the metallurgical industry, it is mainly used to produce metal powder and metallurgical raw materials and other granular materials.

 

In short, the pellet mill is an important solid material processing equipment. It has important application value in various industries.
