Brief introduction Sand washing machine adopts wheel-like structure and equipped with sand making machine is the necessary sand washing product. It can wash stone power and residual away from the mixed sands produced by sand making machine, which can improve the sand quality mostly. XSD sand washer, adopting advanced technology and taking the stone sand industry¡¯s practical condition into consideration, is applied for washing, grading and dehydrating in sandstone factory, construction site, hydroelectric station dam, glass manufacturing and oil well development. Working principle The electric motor runs slowly with the impeller after decelerated by the belt, decelerator and gears wheel. The sand and stone flow into washing launder from feeding launder, rolling with the impeller, and grinding with each other. The impurity covering (on) the sand is washing away. Adding more water at the same time, the strong water flow will take away waste and some low-weight wastes from washing launder. The above is the whole washing process. The clean sand and stone is lift up by vane. When it goes up slowly, the water begins to drop through the mesh and fall back into the washing launder. On one hand, water is removed from the sand and stone; on the other hand, the water can be fully used. Finally, the sand and stone goes to the out launder from the rotary impeller to finish the washing task. Features 1. Reasonable structure.The impeller drive bearing is isolated from water and materials buried in washer,which greatly avoid the bearing damaged because of soaking in water,sand and other pollutants. 2. Compared with the spiral sand washing machine, the loss of medium and fine sand and powder is minimized, and the grade and fineness can meet the required standard. . 3. High output and low power consumption. 4. Longer service life and convenient maintenance.

Brief introduction This Y series vibrating screen is vibrated by the circling motion. It is high efficient screen for filter materials into multiple grade according to the gravel 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 materiel sieve drip line is long and more sieving specifications. The circular vibrating screen can also be used for production classifying in quarry, mine, construction, electricity, chemical industry,etc. Working principle 1. The vibrating screen uses the motor to drive the eccentric shaft to make the screen body periodically along with the direction of vibration force. 2. The materials make circular movement on the screen to realize sieving. Features 1. Vibrating screen YA is of several 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, etc. 4. It is widely used in separating gravel and is also suitable for mining, construction material, transportation, energy, chemical industry and so on.

Brief introduction GP series tailing recovery screening machine is specially designed for metal tailing recovery, which combines with the characteristics of metal tailing on the basis of GZ series high frequency sieve. It is mainly used for iron ore, copper, gold and aluminum ore tailing dehydration. It is a new type tailing recovery machine which is designed to focus on solving problems existing in many tailing recovery screening machines in domestic. GP series tailing recovery screening machine has features such as simple structure, low cost, high efficiency, low consumption, low noise and easy maintenance, etc. Working principle GP series mine tailing screen is driven by two vibrating motors, which make the screen sieve move to-and-for on line to achieve the filtering purpose. With the vibration of the screen, the concentrated tailing materials are continuously threw up and down on the screen, and the materials are loosen and crashed to the sieve, the small size materials are filtered away from the sieve holes. Finally it reaches the aim of classifying, dehydrating and desliming. Technical benefits: 1. High efficiency, strong vibrating force and large capacity. 2. Simple structure and easy operation and maintenance. 3. 45¡ãangle install increases the dewatering area. 4. Vibrating frequency is adjustable to meet different ores. 5. Torsional shear type high strength bolts are used between side plates and beam. No weld gap avoids side plates cracking during vibrating. 6. Polyurethane screen with better elasticity and less blocks. The PU side push plates protect the equipment from the rushing material and guard the long life of the whole device.

Brief introduction Base on lower water content sand is well needed and sold in market, we do research and manufacture a series new type dewatering screen. TS dewatering screen is mainly used in mining, construction for coarse or fine sand dehydrate processing.With the advantages of simple structure and easy maintenance, it becomes a hot seller in our market. Working principle Dewatering screen adopts dual-motor self-synchronization technology. The motors coordinate with universal eccentric and adjustable amplitude vibrator. When the two motors start to work, the vibrators move reversely at the same time. The centrifugal forces is generated by the eccentric blocks will superpose themselves and form a single direction vibration. The high frequency vibration drives the screen move back and forth in line repeatedly. So the sand can be dehydrated and filtered. Features 1. Advanced structure, light weight, high dehydrating ratio with new type vibrating motors. 2. Simple structure, easy maintenance. 3. Cross beam and screen body connect with high strength bolts, no welding and easy to remove and maintenance. 4. Polyurethane screen (PU) high screening ratio, big capacity,long service life and no blocking. 5. Widely used, less replacement parts.
