Solid recovered fuel is prepared from non-hazardous waste and used in incineration plants or collaborative incineration facilities to achieve energy recovery and reuse.At present, the main solid recovery fuel preparation technologies include drying and mechanical separation. Drying can be divided into thermal drying and biological drying. Thermal drying is to heat domestic waste through external heat sources to reduce the moisture content of materials in various forms, while biological drying is mainly to use microbial degradation to generate heat to reduce the moisture content.Biodrying Treatmentbiodrying treatment refers to the principle that under the condition of forced ventilation, microorganisms use the perishable organic matter in the mixed garbage to ferment to produce heat, ventilation under high temperature to accelerate the evaporation of water, and use the warm air to carry more water than the cold air to take away the water in the garbage, thus realizing the purpose of biological drying.

PVC was once the largest plastic in the world and occupied the key raw material position in the chemical industry for a long time. Even now, the position of polyethylene exceeds PVC plastic, but PVC is still the second largest market. Especially in the field of PVC plastic recycling and reuse, not only the amount of waste PVC plastic is large, but also the PVC particles after pretreatment are widely used. Just using a shredder for simple processing, you can realize the crushing of PVC plastic, slightly increase the roller screen, iron separator, sorting machine, granulator, etc., you can be reprocessed into new PVC particles raw materials, but also the price is not cheap.PVC plastic processing can be used to press, extrusion, injection, coating and other ways, according to different types of processing into the corresponding materials and products. Among them, PVC door and window profile belongs to the profile plastic, which is the largest field of PVC consumption in our country, accounting for about 25% of

The technology of cement kiln collaborative disposal of household garbage relies on the original decomposition furnace, rotary kiln and other high-temperature kilns of the new dry pre-decomposition clink production line to realize the reduction, resource and harmless of household garbage. Due to its high disposal efficiency, less investment, short construction period, thorough disposal of harmlessly, good environmental protection indicators and other advantages, it has been more and more widely used.The collaborative disposal of solid wastes in cement kilns is divided into two processes: solid wastes pretreatment and incineration. The pretreatment process is to pre-treat the original ecological garbage by crushing and screening, and finally form two parts of combustible and non-combustible. Fuel generally includes waste plastics, paper, rubber clothing, tree branches and leaves, etc. Because it has a certain calorical value, it can be used as an alternative fuel to burn in the decomposition furnace of the

How big a motor does it take to shred cloth? In the case of unclear material conditions, output, and output size, it is actually difficult to answer this question accurately. Because the shredder motor has a certain power, the higher the speed, the lower the torque. The speed is related to the output of the shredder, and the torque is related to whether the cloth can be shredded. For example, the cloth that enters the bulk material can be shredded with a small torque, while the cloth that is bundled requires a larger torque.Usually shredded fabrics use a 22-250kw motor. If you want a more accurate answer, you must first figure out the requirements of material conditions, output, and output size, etc., so that professionals can recommend the appropriate motor size for you based on experience.Cloth shredder motor selection criteriaThe motor of the cloth shredder is selected according to the power required for the operation of the equipment. If this equipment only needs a 100KW motor, but you choose a 170KW

The output particle size of the twin shaft industrial shredder has a great relationship with the materials to be processed. For example, when the twin shaft industrial shredder crushes bulky waste such as sofas and mattresses, the output particle size is mostly between 100-300mm, while it crushes kitchen waste, the output particle size is mostly 20-200mm. Therefore, the output particle size of the twin shaft industrial shredder is generally between 20-300mm, which can be adjusted according to specific needs. If you want a finer output size, the twin shaft industrial shredder is not suitable (the reason will be mentioned below), then you can consider configuring a fine shredder.Twin shaft industrial shredder shred different materialsWhat is the main decision of the output particle size of the twin shaft industrial shredder?After the crushed material of the double-shaft shredder is determined, the output particle size largely depends on the choice of the blade. A suitable blade can not only shred the material

Recently, many customers have asked us a question, what power motor does the pre shredder machine use? In fact, this question is not difficult to answer, but because the models of pre shredder machine s used in daily life are different, the power of the configured motors is also different. Take our pre shredder machine as an example, the motor power of the smaller model GD6 is 22-45kw, and the motor power of the larger model GD15 is 132-250kw, so our pre shredder machine uses 22-250kw motor.It is very important to choose a suitable power motorThe pre shredder machine is driven by the motor, so it is very important to choose a good motor. If you choose a large one, it will be wasteful, and if you choose a small one, it will not move, and it will easily burn out the motor, causing unnecessary losses. Therefore, users must be cautious when choosing a motor.How to choose the motor power?The motor power of the pre shredder machine is selected according to the power required for the operation of the equipment.
