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.

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...

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...

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.

Y series multilayer circular vibrating screen is high efficient sand vibrating screen.  It filter materials into multiple grades according to the size. For the compact structure and the convenient installation, it is the ideal screening device for prefilter of the feed materials before the primary crushing in the quarry site, it also can be used as separation and filtration solely. The vibrating screen adopts cylinder type eccentric shaft vibrator and partial block to adjust the amplitude. The material sieve drip line is long and more sieving specifications. 1. Vibrating screen YA is of double decks to four decks whose moving track is round. 2. The moving track of material is very long; the size of material can be separated into several specifications. 3. It adopts cylinder style inspiring vibrator device and eccentric shaft to adjust. It has the features of reliable structure, strong vibrating generation, high screening efficient, low noise, easy maintenance, safe performance, et...

The Trommel Screen is also called rotary screen or drum screen, which screening the material into different size. Washing: The bucket is driven by the motor through the reducer and rotates in circle. There are many sand storage web grooves and bucket screen for sand storage and primary dewatering. When the bucket moves, sand can be put out by sand storage web groove after being cleaned in the cleaning tank and primary dewatered on the bucket screen. Recycling: Flowing slurry water is extracted by slurry pump, fine sand is collected by the centrifugal force of the cyclone, then fed to the polyurathane screen from the apex spray. The 0.16-3mm fine sand and water are efficiently separated through the vibration screen. Dewatering: coarse sand (3-10mm) and fine sand (0.16-3mm) are fed onto polyurathane vibrating screen for dewatering.
