Pellet feed is made of particles machine

Time of issue: : 2016-09--09
Particles is roughly divided into two kinds, flat die feed pellet machine and ring die pellet machine, see you every day how much is the production of pellet feed required, if lower productivity can choose 300 flat die pellet machine, if the required quantity is larger then choose ring die pellet machine, ring die is generally small and medium-sized farms and feed mills. Less than two tons of words every day you are advised to choose the flat die pellet machine. Compound feed is the most important material base, modern chicken is developed on the basis of modern science and technology, effectively promoted the development of the poultry industry in our country. Similarly, 3-yellow production has changed the traditional breeding way USES the compound feed, single feed make 3-yellow production level has greatly improved. Such as quality 3-yellow and local varieties of feed remuneration increased from 4.5-5 to 1 to 3, 4:1. Compound feed is according to the varieties and the growth days of age, the production performance aspects of requirements, standard according to nutrition and feed formula, will form the diet of chicken of various feed ingredients ground into powder, mix evenly into the feed. Compound feed according to its shape, can be divided into powder and pressed into feed of granular particles. According to its nutrition ingredient into perfect compound feed and compound feed, concentrated feed.

The use of feed machinery and maintaining this is very important

Time of issue: : 2016-09--09
Equipment vibration fault     Feed factory most of the key equipment for rotating machinery, such as granulating machine, extrusion machine, mixer, crusher and its auxiliary fan, etc. Rotating equipment often violent vibration failures, and unable to work. Vibrations can be caused by many reasons, first, we should consider the bearing failure. Bearing defects can lead to severe shock, serious noise, and even cause equipment damage. Bearing according to the structure can be divided into rolling bearing and sliding bearing. Rolling bearing in the process of operation in case of improper assembly, poor lubrication, foreign bodies to enter and overload, and so on and so forth, are likely to be premature damage, mainly for wear and tear, damage to the cage, and outer ring fracture and plastic deformation, etc. Bearing clearance is when one side of bearing inner ring or outer ring fixed, the other party to do radial or axial movement of the mobile. Use the longer bearing, normal wear and tear, the greater the clearance is, the greater the equipment vibration will increase, the need to replace new bearing. For pelletizer, bearing clearance can be fixed on the spindle, the spindle bearing inner ring load up to check and measurement are added to the rotor. Bearing installation to master a principle, that is, can pass through the corresponding ring installation force or moment, usually adopt force fit, heating to install. In addition, the lubrication of the bearing is one of the important factors about its performance and lubricant and lubricating way appropriate or not will affect the service life of bearing. Through lubrication, can reduce the channel and the steel ball of rotary friction, sliding friction of ball and cage, cage and channel guide surface sliding friction, take away from heat and other external bearing internal friction heat, prevent bearing heating. The filling quantity of the grease with the shell structure and volume of different and different, generally filled to capacity of 1/3 to 1/2. But for low-speed bearing, so as to prevent the entry of foreign body, sometimes padding to 2/3 ~ 1. Second, we should consider the equipment vibration due to unbalanced rotor. The main cause of unbalanced rotor are: rotor scale, the counter weight loss, rotor deformation and the rotation center and the center of mass is not coincidence, this usually does not consider, equipment factory are made of dynamic balance). Finally, you need to check whether there is any loose on a foot, the equipment is installed in strict accordance with the specification, the connection is loose, the coupling gap (normally 2 ~ 3 mm), flatness, perpendicularity adjusting is appropriate. Equipment production is low Ring die pelletizer low yield factor A and bell ring die surface surface rolling, needs to be chamfer. B, ring die compression ratio improper selection. Selection principle: livestock and poultry feed 9 ~ 13; Fish feed 12 ~ 15; The shrimp feed 20 ~ 25; Heat-sensitive feed 5 ~ 9; The grasses and straw feed 6 ~ 9. C, die blocked. By the ring die tapping blockage in the outgoing hole, removal of impurities. D, ring die opening rate is too low, leading to lower productivity. Roller wear factor A and roller shell, need to change in time. B, a new ring die and old roller, roller and ring die will lead to the low yield. New ring die with roller shell should be adopted for granulating, the whole contact pressure roller and ring die clearance is consistent, to achieve uniform wear. Conditioning device blade factors influence material conditioning effect after blade wear, material mixing, steam absorption effect is poor. Conditioning implements material softening is bad, affect the particle pulverizing rate and yield. Tempering temperature factors Tempering temperature is too low. Suggested control in: livestock and poultry is expected to 70 ~ 88; Fish is 82 ~ 95; Shrimp is 90 ~ 105; Heat-sensitive feed 45 ~ 69. Unit: ℃. Steam quality factor points cylinder pressure should be ≧ 0.6 Mpa; The vapor pressure of 0.1 ~ 0.1 M working properly after decompression, to ensure that the steam for excluding the saturated steam condensed water. Mill production low A, check whether the material has been shattered section at A time. B, material is added in the secondary mixed oils. C, the formula of raw material whether to add the silkworm chrysalis. D, the guide plate and the host are consistent. E injection is normal, whether the electromagnetic valve, filter cloth is blocked. F, dust collector fan configuration errors, the fan to error. G, hammer sieve clearance is not appropriate, hammer badly worn. H, severe pressure sieve plate wear. I, sieving slice mode of hole is wrong, opening rate is too low. J, impeller feeder for the opening of the tuyere not open or inappropriate. K, raw material moisture content is too high. L, mesh aperture is not in conformity with the requirements, leading to excessive crush material. M, who did not use the origi
