When anaerobic fermentation of food waste was used to produce biogas, it was found that if the cellulose content of the material was high and the degradability was small, reducing the particle volume of the material by chopping could increase its gas production, speed up the digestion rate and reduce the digestion volume. Typically, gas production can be increased by 10% to 20%.Shredded kitchen wasteAlthough reducing the particle size of organic solids can significantly promote anaerobic digestion, it is not the smaller the better. Within a certain particle size range, the improvement of biogas potential has nothing to do with the smaller particle size of the material. When the particle size was between 5 and 20 mm, reducing the particle size could not significantly increase the gas production. Therefore, the crushed material size of the industrial food waste shredder biogas should be controlled within 5~20mm, so what shredder machine is used to produce biogas? Today I recommend such a device to everyone.

Municipal solid waste is a composite material composed of soil, plastic, waste paper and organic matter. There are currently two mainstream shredding methods: pure tearing or pure shearing. The characteristics of these two types of knives are that they are easy to design and can be processed by wire cutting.However, in the actual use of municipal solid waste shredding, the single shredding method to deal with composite materials is either low in output or huge tool loss and poor economy, so secondary shredding (pre-shredding + secondary shredding) is often used. . If the material is not so complicated and difficult to shred, it is also possible to use a separate shear shredding for economic reasons.What shredder machine will be used in the shredding method mentioned above? Let us briefly understand below.Common equipment for shredding municipal solid wasteShredding is one of the important auxiliary operations in the process of domestic waste treatment. The main purpose is to make large materials smaller and

Broken bridge aluminum is widely used in the construction field, and a large amount of broken bridge aluminum waste is generated every year. In the process of recycling broken bridge aluminum, the collected aluminum is first cut into small pieces. After size reduction, the aluminum shreds are fed into a decoating machine to depaint paint or other materials. The decoated shreds are then melted in furnaces and further produced into ingots, which are used as raw material to make new aluminum products. Broken bridge aluminum crusher is a device that can crush aluminum into small pieces. Let's take a look at the machine through some pictures and videos.Recommended model of broken bridge aluminum crusher In recent years, GDI double shaft shear crusher is often used to crush broken bridge aluminum. Its low-speed, high-torque working principle is ideal for crushing aluminium of different sizes. Secondly, the opposite shear force of the equipment cutting machine can cut the aluminum into smaller pieces, which is very

The basic idea of landfill waste treatment is to use the corresponding resource utilization technology to make most of the waste reusable, and the waste that cannot be reused will be re-landfilled, so as to achieve a great reduction and resource processing of landfill waste.Landfill waste disposal methodsThe commonly used landfill waste treatment method is to dig out the landfill waste and then crush and screen it, and classify the waste according to the type of material utilization. After classification, the combustible materials can be used for incineration and power generation, and the humus can be used to cultivate urban landscape vegetation, the unusable material is landfilled. After treatment, more than 70% of the landfill storage capacity can be restored.Landfill waste treatment equipmentDifferent projects have different processing technology routes, so the equipment used is also different. However, the equipment often used in the current mainstream landfill waste treatment methods are: waste transfer

Plastic film has now been widely used in agriculture, food, medicine, chemical industry and other fields, bringing great convenience to people's lives, but the recycling of plastic film has always been a big problem in the environmental protection industry, and the recycling rate of plastic film is particularly low. It's not that people don't want to use it, but that there is a lack of reliable and effective equipment to assist. The advent of plastic film shredders has solved this problem to a great extent!Plastic film is a soft material with strong entanglement. It is very difficult to recycle and reuse. If you want to shred it, you cannot use traditional fast-knife shredding equipment. Traditional shredding equipment is easy to be stuck during the shredding process. Strong winding materials must use a professional plastic film shredder. Today, dual-shaft shearing shredders, dual-single-shaft shredders and single-shaft shredders are often used to shred plastic films. The following will introduce these three

As the population increases and medical conditions improve, the amount of hospital waste is also increasing year by year. The disposal of hospital waste is a problem that cannot be ignored. If hospital waste is not properly disposed of, there can be a variety of toxic substances, the researchers said.To reduce the toxic hazard of hospital waste, there are three main ways to effectively dispose of hospital waste:Disinfection and destructive reduction treatmentBurn in timeIf it cannot be incinerated, it should be landfilled after disinfectionThe first two processing methods require equipment for shredding medical hazardous waste, so which shredder is suitable for shredding medical hazardous waste? Below is one recommended for you.GDI series twin shaft shredders from GEP ECOTECH are ideal shredders for medical hazardous waste disposal. The equipment can be customized according to the characteristics of the specific materials to be disposed of, and the transmission components of the quality brand ensure the

Which equipment model should be used for a 20-ton wood shredder? A customer asked me this question today. In fact, the wood shredder with this output is considered a medium-sized equipment in our equipment. For example, the output of our GDB double shaft shredder can reach 10-60 tons/hour, and the GDB115 model is often used as a 20 tons/hour wood shredder. Then let's take a closer look at this 20-ton dual-shaft wood shredder!The role of 20 ton wood shredderThe waste wood can be processed into small pieces by a 20-ton wood shredder, which only changes its appearance and shape, but does not change its chemical properties. It still has good comprehensive material properties and can be widely used in the production of wood products.Why choose GDB double shaft shredder as 20 ton wood shredderGDB double shaft shredder is a new type of ideal waste wood shredding equipment. It has the advantages of large torque, high output and wide material applicability. It can tear, cut and extrude wood of different lengths into

The main components of building materials are bricks, stones, concrete, wood, metal, etc. These components can be recycled into recycled aggregates after a little treatment. The recycling of building materials is inseparable from the pretreatment link. building materials recycling plant can turn the building materials is made into recycled products trough a series of preparation measures, generally including several processes such as coarse separation, crushing, sorting, and screening.Coarse separation of building materialsThe increasingly complex decoration and decoration projects increase the amount of building materials generated and increase the difficulty of subsequent processing. To a certain extent, the mixed collection of building materials increases the investment in subsequent treatment equipment and reduces the efficiency. Sorting and collecting building materials at the source can greatly improve the recycling value of the main components.Building materials crushingThe crushing of building
