2Made of bearing steel, high hardness, good wearing resistance, long life, different tooth depth and shape at option;
3 Tooth surface forms of roller shell, good to pelleting performance
4 Frequently-used roller shell tooth form:honeycomb,scallop shape and scallop shape with edge banding
5 Honeycomb,scallop shape, the two types of roller shell is mainly used in livestock and poultry feed pelleting.
6 The advantage of honeycomb rolller shell is the even wearing of ring die, but coil performance is bad.
7Scallop-shaped roller shell features good coil performance, widely used among feed mills, but wearing of ring die is not even.
8Scallop shape with edge banding, this kind of roller shell is applicable for aqua feed. Feed is not easy to slide towards both sides when being extruded.

Product Description:
Roller shell, commonly known as roller, is one of the main work parts in pellet mill and is applied for processing various kinds of biomass fuel granule, animal feed pellet and other pellets. It is made of wear resistant alloy steel with carburization heat treatment, featuring even hardness and long service life. It is divided into tooth through type, tooth no through type and pass type. Rolling parts such as inner eccentric shaft are precise in size, facilitating space adjustment by customers between roller and ring die according to production requirement. It is also characterized by ease of mounting and replacing.

3.New ring die should match new roller to use.Roller connecting with ring die must be loose in front and tight in back.When roller two sides appear sharp corners, it should be timely used hand grinder to blunt the flange part so as to have a good connection of roller and ring die.
4.Before raw material fed into pellet mill,precleaning and magnetic separation treatment is necessary in order to minimize iron impurities of getting into die hole.Checking regularly the die hole is also essential to see whether the die is blocked and accordingly clean the blocked die hole.

Benzene series intermediates

Benzene, an organic compound, is the simplest aromatic hydrocarbon with a chemical formula of C6H6. At room temperature, it is a sweet, flammable, colorless and transparent liquid with carcinogenic toxicity and a strong aromatic odor. It is insoluble in water, easily soluble in organic solvents, and can also be used as an organic solvent itself. The ring system of benzene is called benzene ring, and the structure after removing a hydrogen atom from the benzene ring is called phenyl, which is represented by Ph, so the chemical formula of benzene can also be written as PhH. Benzene is a basic petrochemical raw material, and its output and production technology are one of the symbols of a country's petrochemical development level.

On October 27, 2017, the list of carcinogens published by the World Health Organization's International Agency for Research on Cancer was preliminarily sorted out for reference, and benzene was included in the list of Class I carcinogens.

The benzene ring is the structure of the benzene molecule. It is a plane regular hexagon, each vertex is a carbon atom, and each carbon atom is combined with a hydrogen atom. The carbon-carbon bond in the benzene ring is a unique bond between single and double bonds, with a bond angle of 120° and a bond length of 1.40Å
