In the sand washing production line , the ore dressing operation is very important. With the increase in environmental protection in recent years and the tight supply situation of domestic mineral resources, we have to use the tailings that were once overlooked. The tailings are ignored because the residue cannot be further sorted. However, with the development in recent years, we have found that tailings are not completely useless waste, and often contain other ingredients that can be used for other purposes. The processing technology and development and utilization can effectively “turn waste into treasure”, which not only eases the resources and environmental pressure but also realizes the comprehensive utilization of tailings! The tailings zero discharge system is a specialized treatment system specially developed for the tailings dry discharge and tailings slurry zero discharge in the mine beneficiation industry. Compared with the traditional tailings treatment method, what ar...

Both the circular vibrating screen and the linear vibrating screen are motor-driven screening equipment. However, their working principle and suitable materials are also different. When selecting the vibrating screen, it should be selected according to the type of material to be sieved and the particle size. Suitable shaker. Linear screen features When the linear vibrating screen is working, the trajectory of any point on the screen box is a straight line, that is, when the eccentric block rotates, only one force is generated in a certain direction. Then the vibrating screen only performs a linear motion of the plane reciprocating in this direction. The material enters the feeding port of the screening machine uniformly from the feeder, and several kinds of sieve tops and sieves are produced through the multi-layer screen and are respectively discharged from the respective outlets. The linear vibrating screen has a large processing capacity and good dewatering effect and is su...

Selection of width and length of the screen surface The width and length of the screen surface is an important process parameter for the screen. Generally speaking, the width of the sieve surface determines the processing capacity of the screening machine. The length of the sieve surface determines the screening efficiency of the screening machine. Therefore, the width and length of the sieve surface are correctly selected to improve the production capacity and screening of the vibrating screen machine . Efficiency is very important. The width of the screen surface is not only affected by the processing capacity of the screen, but also by the structural strength of the screen. The larger the width, the more certain the size of the screening machine is. The more problems that need to be solved in the structural strength of the screening machine , the more difficult it is, so the width of the screen surface cannot be arbitrarily increased. The length of the screen surface affec...

A. Preparations before construction: The materials and accessories required for construction are fully prepared (three types of I-beam, channel steel, steel plate, electric welding machine, wire, bar, chain, 2 pulleys, 4 inch steel pipe, 3 inch steel pipe, 2 sets of oxygen acetylene, sand, cement, red brick, air duct, wind raft 2, etc.). The lifting beam is made to ensure that the lifting trommel screen is firm and reliable. Before construction, the construction supervisor will lead all construction personnel to learn the measures. The construction personnel must arrive at the construction site 30 minutes in advance to familiarize themselves with the operation of the on-site equipment. The person in charge of the construction shall have a clear grasp of all the lines, equipment and materials on site. The person in charge of construction assigns the tasks of the construction personnel on site and makes the construction personnel clear their respective tasks. B. Precautions during...

Sand washing wastewater refers to the wastewater generated by the washing sand and gravel production enterprises in the production process. Sand and gravel is one of the basic materials of the building. With the increasing demand for domestic sand and gravel, the natural sand is facing the reduction of resources and environmental protection. The pressure, washed sand will be used as an important source of construction sand in the building materials market. Washed sand can be widely used in concrete, mortar and products. It has become a good market prospect in modern construction projects. The replacement of natural sand in quality and quantity is one of the signs that the artificial sandstone production line has entered a new era of development. Characteristics of sand washing wastewater The sand washing wastewater is the water produced by sand dewatering screen . The main pollution factors are chemical oxygen demand and suspended solids, and the suspended solids content is the...

Vietnam has a population of near 1000 million. Yunnan is carrying out infrastructure construction all over the country. Experts that the country could run out of sand within five years due to over-exploitation of the natural product, local media reported. The artificial sand can be used to instead the natural sand. It was produced by sand making and sand washing machine . artificial sand has many advantages such as: The factory production can establish a quality control system from a series of processes such as material selection and crushing. The physical and mechanical properties of sand can be consciously selected to produce hard rock sand, avoiding the use of soft, weathered rock, and the amount of mud (block) can be manually screened. The artificial sand is 10~20% cheaper than natural sand. The particle grading and fineness modulus of the mechanism sand can be adjusted. According to the needs of the project, combined with the characteristics of the base metal and...

The fine sand recovery system consist of screw sand washing machine , vibrating screen , cyclone. The vibrating Screen was combined with cyclones. Ordinary sand wheel washer or screw sand washing machine can’t process fine sand below 3mm, we researched vibrating screen with cyclone machine.   sand recycling system The cyclone is a separation and classification device. When the two-phase mixture to be separated is tangentially introduced into the cyclone from a periphery of the cyclone at a certain pressure, a strong three-dimensional elliptical strong rotational shear turbulent motion is generated. Lzzg's dewatering screen https://www.lzzgmachine.com and sand recovery machine have excellent performance. Compared with Yunnan's local ordinary vibration dewatering screen, the sand washing machine output is twice as high, which greatly improves the production efficiency of the whole line.
