Ring die pellet mill technical performance of Liaoning ring die pellet mill Sanli heavy equipment plant

The following are some of the main biomass materials molding process parameters at different requirements: cotton stalk thermoforming process parameters: temperature between 150 ~ 260 ℃, particle size between 0 ~ 12.5mm, the moisture content of 6% ~ 10% between. Cornstalks thermoforming process parameters: raw material moisture content of 5% to 15%, the optimum moisture content of 10% to 15%, raw material particle size between 1 ~ 5mm, the temperature is about 110 ℃. Wheat straw thermoforming process parameters: raw material moisture content of 5% to 18%, the best moisture content of 10% to 15% and a temperature of about 110 ℃, feed particle size 1 ~ 5mm. Rice rod cold molding process parameters: Forming pressure 32MPa, the moisture content of 10%, the raw material particle size 4mm, add binder ratio of 4:1. Husk thermoforming process parameters: rice husk small size, screen out debris can be used directly, the heating temperature is 80 ~ 111 ℃, the moisture content of 15.4% to 17.5% molding pressure 8.8 ~ 11.5MPa, binder added than It was (2.85 ~ 4.25) :1. Biomass pellet production line equipment: rotary dryer Product Description: rotary dryer is the material heating and drying equipment. Coaxial sets of columns rotating barrel material, the spiral blade and interrupted spiral lifting plate between the inner and outer cylinder exhumation and Jan materials obtained during drying. Rotary dryer is mainly used in mineral processing, building materials, metallurgy, chemical industry, biomass feedstock and other departments drying certain humidity or granularity of the material. Mainly by the horizontal cylinder cylinder, exhaust pipes, feeding device, a feeding device, screw barrel, cleaning device, dial plate, the wind device, gear, dust removal equipment and electrical control equipment. Features: 1, solve with traditional dehumidifying dryer downstream due to the movement of water vapor over the return of the material after the system temperature. 2, in the drying process, the hot air from the rear forward motion, full contact with the material, by heat conduction, convection, radiation, heat transfer fully utilized. 3, the heat directly to the material, so that the material is constantly being evaporated moisture in the cylinder body, the feed inlet of the wind means a lot of water, wet gas stream is withdrawn to prevent secondary pollution caused by dust efflux. 4, through the inner spiral stirring, sweeping loose, copy board, to promote the movement of materials to complete the drying process. 5, countercurrent conduction dehumidifying, avoid drying program to reduce duplication. Analysis of vertical ring mold particles granulator process stability and energy-related factors vertical ring die pellet mill because of the prepared particles good quality and high efficiency in the related field of industrial production, biomass energy industry has been widely used. At present, China's ring die pellet mill products remains poor stability, short life, higher energy shortage has seriously hampered the development of related technologies and industries. Gongyi City, Henan Sanli heavy equipment factory on the basis of analysis of relevant factors granulation process stability and energy on, high stability, low power consumption granulation technique has been studied mainly as follows: (1) The ring die pellet forming into the mold, roll and roll the die hole in the squeeze between the two processes, respectively, two of the material during the mechanical analysis, and based on grab angle and height granulation solving the factors influencing the granulation process . (2) for the ring mold die hole arrangement under existing easy-cracking problem, designed two new die hole arrangement, three ring mold and the finite element analysis results show that with the new arrangement of mold hole help to improve the strength of the ring mold. (3) analysis of the ring mold width is affected by changes in its force and strength, the results showed that with the increase in the width of the ring mold ring mold overall amount of deformation increases, the feed end easier to crack. (4) Experimental study of particle machine vibration ring mold different widths and line speed combinations, and has been the optimum combination of parameters such that minimal vibration. (5) The high rolling granulation process was simulated by changing the model parameters to explore the influence of various factors on the rolling process. The results show that with the increase of the friction coefficient and the mold roll diameter ratio is reduced, the powder material compression molding nip better quality. (6) of the die hole extrusion process was simulated to obtain the required material granulation extrusion pressure and rolling and extrusion die orifice to analyze the process together, and then put forward a pellet machine parameter optimization saving The design process.
