Feature of FDSP roller shell
1Roller shell,made of wear resistant alloy raw material, processed by fine and heat treatment;
2 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  form:honeycomb,tooth shape with open edge and tooth shape with close edge.
5 Honeycomb,tooth 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.
7 Teeth type roller shell features good coil performance, widely used among feed mills, but wearing of ring die is not even.
8Teeth shape with close edge, this kind of roller shell is applicable for aqua feed. Feed is not easy to slide towards both sides when being extruded.
We are the largest professional roller shell and shaft manufacturer in China.90% for exportation .
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.
Â
It is made of wear resistant alloy steel with carburization heat treatment, featuring even hardness and long service life.
Â
It is divided into tooth through type, tooth no through type and pass type. Rolling parts such as innerÂ
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.

Why say closed cooling tower is energy saving and environmental protection equipment, more and more users are using this kind of equipment to replace the original equipment (open tower), we can through data analysis and comparison, the two energy data accounting can be obvious. Energy consumption is basically two major aspects, one is water, the other is electricity. Both are energy costs that no cooling tower can escape, unless you leave the equipment on.
First of all, look at the consumption of water. Water is generally consumed in two aspects. One is the flying overflow after spraying, and the other is the evaporation consumption of water.
Let's look at the open cooling tower, the spray water of the tower is basically between two and three percent of the overflow rate, if we according to the daily operation of 10 hours, excluding holidays, 280 days of operation. According to the actual open cooling tower flow of 6000 cubic meters per hour to calculate. 6000*2%*10*280= 336,000 tons of water, and the same closed cooling tower, its spray flying overflow is very small, because after all, the spray work is carried out in the tower, almost can be controlled in a few thousandths, we calculate according to 5 thousandths, the same is 10 hours of work, 280 days a year operation, To achieve the same cooling amplitude is basically 4,500 tons per hour of closed cooling tower is enough, then the calculation results: 4,500 *0.5%*10*280= 63,000 tons, it is not difficult to see, because of the different design structure caused by the waste of spraying water resources, more than 200,000 tons of terror. The bigger the pool of the open tower, the more wasted water, because the evaporation area increases, and the closed cooling tower has no pool, so the consumption here is zero. Judging from the price of a ton of water, just such a equipment, a year to solve the capital of hundreds of thousands of enterprises.
Let's look at the comparison of electric energy, electric energy is not different, because they are all through the same power equipment to operate the equipment, the power of the two is similar, the running time is the same, basically the energy consumption is about the same.
To sum up, for the closed cooling tower energy saving accounting can be strong to open the tower out, and, today are advocating energy conservation and environmental protection, this is the general trend, so the closed cooling tower is more and more favored by the majority of users.
