wheel type sand washer Is the processing capacity of the wheel-type sand washing machine suitable for large-scale sand making plants? Because the traditional sand washing machine inevitably causes the loss of a large amount of fine sand during the cleaning process, so that a lot of wealth is also lost. The wheel bucket sand washing machine has a high cleaning height, reasonable structure, large output, and less sand loss during the sand washing process. sand machine. The wheel type sand washing machine has a simple structure, and the impeller drive bearing device is isolated from water and water-receiving materials, which greatly avoids the damage of the bearing due to water, sand and pollutants, and greatly reduces the accident rate. The loss of fine sand and stone powder is very small, and the gradation and fineness modulus of the washed construction sand meet the standard requirements. The wheel bucket sand washing machine has almost no wearing parts except the screen, and has a lon

  The placer gold ore washing operation includes three processes of crushing, screening and desliming. It is a very important and necessary operation before the placer gold ore is sorted. The reason why this operation is important is that it not only breaks and separates the mud and sand, but also removes the gold particles adhering to the surface of the gravel, and once a large amount of gold-free gravel can be screened out, it can be discarded directly; the general yield can be It reaches 40%-50% of the ore, and at the same time, most of the slime is removed. In placer gold sorting , desliming, like removing large gravels, is also a very important preparatory operation. Materials less than 0.1mm in placer gold generally do not contain gold or contain very little gold. For example, gold less than 0.1mm in placer gold in Hunchun Gold Mine only accounts for 0.15%, while the same-sized ore slime accounts for 13.77% of the original ore sand. This kind of gold smaller than 0.1mm is commonl

YK series circular vibrating screen can be used for screening fine sand and coarse sand . The rocks suitable for sand making, such as river pebbles, limestone and granite, go through the crusher and then enter the circular vibrating screen to screen out fine sand (sand with an average particle size of 0.25mm~0.125mm), medium sand (0.5~0.25mm) and coarse sand (1mm~0.5mm). If the customer needs a specific size of sand, you can replace the corresponding type of screen. YK series circular vibrating screen is mainly composed of screen box, screen, vibrator and damping spring. The vibrator is installed on the side plate of the screen box, and the motor rotates through the coupling, which produces centrifugal inertia force and forces the screen box to vibrate. The YK series circular vibrating screen is installed with a seat, and the adjustment of the inclination angle of the screen surface can be realized by changing the position and height of the spring bearing.

Sand and gravel are one of the main components of concrete. Sand and gravel play the role of filling and reinforcement in concrete, and play a vital role in the performance and strength of concrete. Sand and gravel act as a filler in concrete. Concrete is made by mixing cement, sand, stones and water in certain proportions. Sand and gravel have a filling effect between particles, filling the gaps in the cement gel, making the concrete more dense and compact. This filling action helps reduce shrinkage and cracking of the concrete and increases its durability. Sand and gravel enhance the strength and stability of concrete. The particles of sand and gravel form a mechanical connection with the cement gel, which increases the cohesion and compressive strength of the concrete. Sand and gravel can also improve the shear strength and impact resistance of concrete, and increase the stability of concrete. In addition, sand and gravel can also disperse the stress between cement particles and imp
