The belt filter press is widely used in urban sewage treatment, chemical, oil refining, metallurgy, paper making, leather, food, coal washing, printing and dyeing, and other sludge dewatering. The machine runs continuously, with a high degree of automation, energy saving, high efficiency, and maintenance. Convenient, it is the ideal equipment for sludge dewatering. Typical use of belt filter press ; suitable for dehydration of residual activated sludge, digested sludge and mixed sludge; suitable for dehydration of sludge generated by wastewater from papermaking, leather, livestock, aquaculture, chemical, food and other wastes Suitable for dewatering of sewage sludge, suitable for dewatering of metallurgical sludge such as blast furnace, converter, sintering, etc. The belt filter press has the advantages of compact structure, novel style, convenient operation and management, large processing capacity, low cake moisture content and good effect. Compared with the same ty...

Low-cost sand washing production wastewater and sludge treatment project overview: The sand washing wastewater is 300m3 / d and the sludge is 30m3 / d. The main production of construction water washing sand primary products. A water-washing sand production line with a daily production capacity of 150 tons will crush, screen, and wash nearby sandstone, silica, etc. to produce construction water-washing sand products. The main environmental pollution problem in the production process of the project is the sludge wastewater and domestic sewage generated by washing sandstone and silica rock. According to the requirements of relevant laws and regulations, sand and stone washing wastewater and domestic sewage must be discharged or recycled after treatment, and the washing sludge should be properly disposed of. The tailings can be exported as good paving gravel. Total wastewater: about 300 m3 / d of washing production wastewater. The main pollutants are characterized by a larg...

kaolin washing process The sand is first removed by a spiral classifier. It is then entered into a hydrocyclone for classification. The sorted coarse concentrate enters a horizontal spiral centrifugal classifier to separate the paint grade and filler grade kaolin. The raw ore is added with water and dispersant according to the set concentration requirements, and is made into pulp in a blender or tamping machine. The purpose of pulping is to disperse kaolin and separate it from sandy minerals and plant impurities, so as to prepare a slurry of suitable concentration for the next process. Screw classifier to remove coarse sand In the raw kaolin ore, the particle size of quartz, feldspar, mica and other impurities is coarse, generally larger than 325 mesh, and the particle size of kaolin is fine, mainly concentrated in -2μm. The spiral classifier can remove most of the quartz and feldspar coarse sand. Use hydrocyclone to sort the kaolin The hydrocyclone is used for sor...

The concept of environmental protection in the mining industry is the mainstream of the current development of the mining machinery industry. The environmental protection machinery set off by the mining machinery industry has become hot. That is the sludge vibration dewatering screen. What is the screening effect of the sludge vibration dewatering screen? We then look down. The sludge vibrating dewatering screen has all the functions of a traditional dewatering screen, and also adds an environmental protection concept. Longding environmental protection dewatering screen has the best sludge vibration dewatering screen. It upgrades and strengthens the sealing measures of the equipment to reduce the sludge wastewater generated from the sludge vibration dewatering screen during operation. For some sludge wastewater that cannot be controlled, a special dust collection device, such as a pulse dust collector, can be added to control the spread of sludge wastewater and reduce environmental ...

Why does sand need to be cleaned Sand often contain a certain amount of soil and dust. If these soils are cleaned, the use of sand will be affected. Therefore, at this time, it is necessary to use sand washing equipment for cleaning, and the sand and gravel after cleaning can be used in our project construction. The sand washer can also improve the purity of the sand and prevent it from sticking together during stacking. Equipment to wash sand Wheel sand washer equipment generally has a capacity of less than 80 tons, so it is suitable for small and medium capacity sand production line systems. The spiral sand washing machine has a relatively strong cleaning ability, which can effectively clean sand and gravel with serious muddy impurities. It is often deployed in large sand production lines. Bucket sand washer 1. It can realize the cleaning, impurity removal and dehydration of the finished sand. 2, can eliminate excess particles of bad sand. 3. The bearing and water are...

How to configure a sandstone aggregate production line and the price? The large-scale environmental protection sand-making plant  mainly crushes large-scale stones into sand that meets the requirements of particle size for later application in various fields. The specific configuration depends on the user’s operating conditions. There are technical teams here based on the operating environment. , Infrastructure construction, investment budget and other tailor-made designs, here are provided two sets of plans for everyone, the specific large-scale stone plant sand and aggregate production line configuration list is as follows; 1. Fixed large-scale sand production equipment configuration, the price is about 60,000 to 120,000 Feeder + Jaw Crusher (Coarse Crusher) + Impact Crusher (Medium Crusher) + Sand Making Machine + Vibrating Screen + Sand Washer + Conveyor; ① The specific length and position of the conveyor can be determined according to the actual site conditions ②...
