silica sand double-drum scrubber machine

The quartz sand scrubber is an important equipment used in the mining industry. It mainly removes impurities and clay stone quality from the surface of the mining through strong operation. The slurry enters the scrubber body through the feed pipe, and produces intense vortex under the strong beater operation of the impeller. The ore particles have huge kinetic energy in it, and produce intense friction and collision with each other. Mining silica sand scrubber double-slot high-speed mixing barrel 20T zirconium silicate sand washing equipment The impurities and thin films wrapped on the surface of the ore particles are not strong, and they can be easily peeled off the surface of the ore after friction and collision. The strong friction and collision between the adhesive-impregnated ore particles on the surface of the ore layer will also loosen and break, thereby achieving the separation of clay and ore particles. These film impurities and clay break and peel off into the ore slurry, an...

High-efficiency gravity thickener instruction

The deep cone sludge thickener is based on the traditional vertical flow sedimentation tank. The structure of the internal feed cylinder is improved, the efficiency of sedimentation is greatly improved, the plane of the sludge thickening tank body is circular, and the suspended solids settle under gravity.In the bottom of the tank, the clarified water is discharged from the overflow weir around the upper end of the tank. The overflow port is provided with a scum filter device and a baffle to ensure the effluent water quality, the underflow concentration is up to 70%, and the treatment capacity is 3-8 times higher than that of the conventional concentrator. The sludge thickening tank is based on gravity and sedimentation which makes solid-liquid separate from each other. The concentration of pulp waste water could be enhanced from 2%~ 15% to 60% ~ 70% by the machine, the clear water is overflow from the upper part of the thickener , so as to achieve the purpose of sewage purification a...

Kaolin beneficiation process

Typical principle process flow of kaolin beneficiation : rough separation adopts spiral classifier and hydrocyclone classification to remove a large amount of coarse sand. Φ42m sedimentation tank, Φ14-20m grading tank and centrifugal classifier are selected for grading, and the particle size distribution is strictly controlled. And according to the quality characteristics of the raw ore of each pit and the product quality requirements, chemical bleaching, high gradient magnetic separation or stripping operations can be taken respectively to obtain different grades of products.

How is railway ballast produced?

If there is no ballast, the rails and sleepers are laid directly on the roadbed, and the roadbed may not be able to bear the weight of the train and sink downward. The gaps and texture between the crushed stones of the ballast play a good role in dispersing the huge pressure generated by the passing of the train, and evenly disperse the pressure to the foundation. The elasticity of the ballast can well disperse the vibration and noise of the train, making passengers more comfortable and protecting the roadbed. The production, storage and loading of ballast are all completed in a dedicated storage and transportation base. The base is generally located in a location close to the railway freight station, which is convenient for production, loading and transportation, and maximizing efficiency. The stone used to make ballast is natural stone. The raw stones that meet the requirements of hardness, wear resistance, water permeability and other indicators will be transported to the ballast pr...

Vibrating screen installation and trial operation steps

Install supporting or hanging devices. When installing the circular vibrating screen, the ground should be shoveled and sturdy to prevent problems caused by uneven ground surface during use. Follow the support or hoisting drawings to operate. The installation of each component should be carried out in strict accordance with the sequence of operations. The spring components should be installed before Match the actual stiffness of the end face mark. Connect the screen box to the supporting or hanging device. After installation, it should be adjusted according to the specified inclination. For hanging screens, the inclination of the screen box and the level of the main shaft of the screen box should be adjusted at the same time. Generally adjust the horizontality first to eliminate the deflection of the screen box. After the level is corrected, adjust the longitudinal inclination of the screen box. The force of the vibration isolation spring should be uniform and the force can be judged b...

Fine sand coarse sand vibration screening machine

YK series circular vibrating screen can screen out various specifications of 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.
