How to deal with coarse grain phenomenon in the production of paper burning machines Date：2025-12-13
　　Paper machines may encounter various problems in the production of paper, which are all caused by different factors. As long as the factors that cause the problems are identified during the production process, the problem can be solved calmly and appropriately. The possible reasons for the occurrence of coarse lines in paper production by paper burning machines are: improper mixing of materials and additives in pulping or papermaking, low solubility, improper blade angle in papermaking, excessive steam consumption, and alkaline white water, which may all cause coarse lines.　　Once the cause of the occurrence is found, it is easy to find a solution to the problem. If it is caused during the paper making process, methods such as controlling steam consumption, replacing rollers, and adjusting the angle of the scraper can be used; If it is caused during the pulping process, measures such as increasing the grinding concentration and beating degree reasonably, beating according to the proportion, and applying additives can be taken.

What are the components of a small paper machine? Date：2025-12-13
　　Small paper machines can be roughly divided into the main machine part and the auxiliary system part;　　The host part is roughly divided into wet parts, cadres, and curls. The wet part can be understood as the part of the paper with a relatively high water content; Cadres are the parts of paper that have little moisture and are considered dry; Curling is the mechanism by which a page of paper is rolled up.　　Referring to the picture content, the headbox, mesh part, and pressure part can be considered as wet parts; Drying, gluing, coating, and calendering are considered cadres; And then there's curling. Please do not delve deeply into the concept of classification as it does not involve academia.　　Auxiliary system, literally, refers to the part that assists the host in implementing its functions.　　For modern high-speed paper machines, each system is complementary and there is no distinction between primary and secondary functions or functions. The auxiliary system is just a term. Just like mobile phones, in addition to making phone calls and SMS functions, there are also various functions such as taking photos, socializing, and wallets to meet people's needs for quality of life and efficiency.

Recycling of White Water in Small Paper Machines Date：2025-12-13
　　White water refers to the water that is removed during the formation of the paper web, as well as the water that is further removed during vacuum box and pressing. The recycling of white water refers to the use of various methods to treat paper machine white water, reduce its suspended solid content, replace clean water and reuse it in the pulp and paper making process, with the aim of reducing the amount of clean water used, reducing wastewater discharge and solid loss. The effective method in a paper mill is to use a paper machine white water circulation system to treat paper machine white water. So, what are the methods?　　There are three methods for recycling white water:　　1. Filtering method, such as thickener, dehydrator, Polydisc filter, etc;　　2. It is an air flotation method, such as an air flotation white water recycling machine;　　3. It is a sedimentation method, such as sedimentation tank, sedimentation tower, sedimentation tank, etc.　　1、 Air flotation method　　Due to the varying difficulty of solids floating in water, the solids in papermaking white water can be divided into three categories: first, for solids with high density that are not suitable for floating separation; Fine planktonic substances and fine flocs that are difficult to function due to buoyancy; Floating solids with high buoyancy, low relative density, or flocculating on the floating platform.　　Traditional air flotation recovery equipment is only suitable for separating and recovering easily floating solids from water, while Poseidon pressurized air flotation machines can effectively remove the three types of solids mentioned above.　　The traditional air flotation white water recovery device is based on saturating the white water with air, causing the solid substances in the white water to adsorb air, reduce its apparent density, and float to the liquid surface for separation.　　Factors such as gas supply volume, white water concentration, and the type and dosage of flocculants can affect their recovery efficiency. The marketing of gas supply volume is relatively large, and it is necessary to control the dissolved air ratio. Excessive air volume can lead to fluid turbulence, damage flocculation, and reduce the air flotation effect; Insufficient air volume will reduce the gas-solid ratio, thereby reducing recovery efficiency.　　Traditional air flotation equipment uses rectangular air flotation tanks, while the Krofta Sandfloat air flotation equipment that has emerged in recent years uses circular air flotation tanks, which have high recovery efficiency. Its operation is based on the principle of zero velocity, providing a brief residence time for white water and shallow (400mm) operating conditions.　　The white water enters the purification tank through a rotating multi tube feeder, which rotates around the center in the opposite direction to the feeding direction. This reduces the movement speed of the white water to a small level, causing a relatively unknown water column to be found in the air flotation tank. The bubbles float vertically on the slurry solid to the liquid surface and are then removed with a sludge shovel.　　2、 Filtration method　　The filtration method is a type of method that uses various forms of filtration media to treat white water and wastewater.　　At present, the representative equipment widely used is the Polydisc vacuum filter.　　The Polydisc vacuum filter has compact structure, wide adaptability, high filtration efficiency, and convenient installation and maintenance, so it is widely used. It is mainly used for the concentration of various pulp and white water recovery in papermaking.　　It uses the vacuum generated by the filtrate water leg tube as the filtering driving force, and the net height of the water leg is generally 5-7 meters. During operation, the liquid level in the machine slot is 100-200 millimeters higher than the centerline of the spindle.　　Each sector on the disk is in different working states during operation. When the sector is brought into the liquid level, it first enters the atmospheric filtration zone. The liquid in the tank is filtered under the static pressure difference, and the turbid filtrate is discharged through the main shaft and distribution valve atmospheric filtration outlet. At this point, the sector begins to hang slurry, and then enters the vacuum zone, A large amount of filtrate passes through the suspended filter screen and is discharged through the vacuum zone filtrate outlet of the main shaft and distribution valve, forming a filter cake on the fan.　　After the fan blade rotates out of the liquid level, under the vacuum suction effect, the filter cake further dehydrates, and the dryness increases to 10%~15%.　　When the fan leaves the vacuum zone and enters the slurry stripping zone, the pressure water will peel off the slurry layer on the fan, fall into the slurry receiving hopper and continue to dilute with water (3% -4%), and be transported to or directly into the slurry tank using a screw conveyor.　　3、 Precipitation method　　The sedimentation method is the use of sedimentation to separate fibers and fillers, achieving the goal of recovering fibers and fillers and clarifying white water. The sedimentation tower is currently a commonly used sedimentation equipment, where white water enters the inner cover of the tower from the top. The function of the inner cover and the diversion pipe is to form a strong rotating fluid with white water and form a stable centrifugal sedimentation form for sedimentation.　　When the concentration of white water is high, the white water will continue to settle in the cone part of the tower. At this time, it is gradually accelerated by the downward flow rate formed by the continuous discharge of tail slurry from the bottom of the tower cone. The settling speed of the concentrated white water entering the cone part forms a stable concentration gradient according to the height of the cone, which is the key to the stable operation of the sedimentation tower.　　Most of the precipitated water, which has undergone preliminary sedimentation, bypasses the edge of the inner cover body, causing the awakened part of the tower body to continue sedimentation at a slow upward motion speed until the overflow ring enters the overflow groove.　　At the same time, the closed circulation of white water will also have some adverse effects. White water contains various dissolved organic and inorganic substances, some of which are harmful. When the white water system is closed, these substances will greatly reduce the amount of fresh water entering the system and the amount of waste water discharged. These harmful substances will accumulate in the system, causing water quality degradation, or producing foam, or sediment and dirt, blocking mesh and blankets and other problems, Affects the wet end and paper forming performance of the paper machine.　　In addition, white water sealing can also have varying degrees of impact on paper performance. According to relevant research reports, after the closed cycle of white water, the strength and tensile strength of wet paper pages are reduced to some extent, which leads to problems such as increased head breakage and reduced operational performance of the paper machine.　　In addition, when the dissolved salt content exceeds a certain value, the main performance indicators of the paper page will decrease. The increase in dissolved solid content in white water also has a negative impact on the tensile strength of paper.

How to Make Pulp with Small Paper Machines for Better Results Date：2025-12-13
　　Quality is an essential step in papermaking, as it is the equipment used to separate plant raw materials into fibers. The pulping methods of small paper machines can be divided into three types: chemical method, mechanical method, and chemical mechanical method. The corresponding pulping equipment includes digesters, wood mills, thermal mills, pulp washers, bleachers, beaters, and waste liquid recovery equipment. And how can the equipment produce better pulp results?　　The pulp produced by pre heating wood slices with steam and then grinding them under high pressure is called hot wood chip ground wood pulp. The machine used to manufacture hot wood chip ground wood pulp is a thermal mill, which consumes a lot of electricity. Therefore, fully utilizing the heat energy during the grinding process is the key problem of the thermal mill; A pulp washing machine is a mechanical device that separates digested pulp from black liquor. According to the extraction rate of black liquor, it can be divided into two categories: high concentration and low concentration extraction.　　The purpose of pulp bleaching is to remove residual lignin and pigments from the pulp after cooking, improve the whiteness of the pulp, and give the pulp a clean white color. Bleaching machine is a widely used bleaching equipment, which consists of components such as a spiral propeller of the bleaching pool and a washing drum. The slurry and bleach are placed in the pool and continuously added with washing water. With the help of a screw propeller, they circulate and flow in the pool, completing the process of mixing and chemical reactions. The water containing bleach products and residual bleach is discharged through the inner chamber of the washing drum, resulting in a clean white pulp.

How to improve paper burning and papermaking machines to better comply with the requirements of the times Date：2025-12-13
　　With the continuous development of technology, equipment is constantly being updated, and the market demand for paper machines is also constantly changing. But for paper machine manufacturers, in order to survive in fierce competition, they need to understand the survival rules of the enterprise and have a sharp eye. For the paper machine industry, it is necessary to innovate and improve paper making equipment such as paper burning machines and small paper machines to meet market demand, in order to obtain more business opportunities without being eliminated by the market.　　In the work of paper making machinery, the ability and cost consumption are all based on the same theme. However, for paper machine customers, regardless of the type of paper making equipment, the first concern is the change in efficiency and low energy consumption. Only in this way can it be welcomed. Therefore, when improving paper making machines, this is an eternal and unchanging direction for improvement.　　We all know that paper machines are used to produce various types of paper, but the current market demand is for the workability of diversified production. If a paper machine equipment can only produce one product effectively and cannot produce other papers at the same time, it will undoubtedly cause customers a lot of losses. This is the second direction and goal that paper machines need to improve.　　Secondly, in the production process, many customers found that the paper burning machine could not play a large capacity. In fact, these reasons are very simple. This is because the paper machine is subject to more external Confounding factors in the production process. In order to make the paper machine play a better role, as long as the paper machine is improved in technology, the product stability is improved, and the paper machine is not affected by external factors, This is also the direction we need to work towards.
