Sand washer
The construction industry is growing by leaps and bounds, fueled by a number of factors including rapid urbanization and changing lifestyles. New construction projects in developing economies are also spurring demand. The demand for mobile sand washers is growing alongside a parallel rise in stationary models. In this article, we look at the different types of sand washers, and how they work.
Functions of a sand washer
A sand washer is a machine that cleans sand, stone, or both. The sand and stone flow into the washing tank on a baffle plate. The water flowing over the impellor carries the impurities and foreign materials away. The clean sand and stone is then lifted by the impeller and falls through a mesh. The water then drops back into the washing tank, where it is fully utilized.
The screw sand washer, also known as a Fine Material Screw Washer, has two types: double screw and single screw. A screw sand washer is used primarily for washing, grading, and dewatering fine-grained materials. These types of sand washers are sized for the amount of minus 200 mesh (74 um) material to be washed. This ensures that the screw will have enough space to wash the material.
Flow meter
A sand washer is a multifunctional equipment used to separate sand and wastewater. It can do grit separation and washing in one single machine. Its low-flow characteristics make it ideal for this process. Furthermore, a sand washer is designed to clean the water in the tank as well as the sand it’s washing. The water flow in the tank is controlled by a flow meter.
Before utilizing a sand washer, you should first inspect the belt and the machine. Replace it if the belt is damaged or too greasy. Also check the bearing and motor wiring, which must be properly insulated and installed in a snakeskin tube. Check the oil level, which is very important for the safety of the equipment..
Types of sand washers
There are various types of sand washers. Some can process materials from 0 to 30mm, while others process coarse particles. Spiral sand washers are characterized by the spiral head that is submerged in the sedimentation tank, and is driven by a motor through a reducer.
Bucket wheel sand washers are ideal for washing fine or coarse materials. They are suitable for cleaning construction sand, gravel, and prefabricated stone, among others. Bucket wheel sand washers are highly popular for their reasonable structure, large processing capacity, low power consumption, and high cleaning efficiency. The main advantages of this type of sand washer are its novel sealing structure, fully enclosed oil bath transmission device, and adjustable overflow weir plate.
Wheel sand washers are also popular. Wheel sand washers are cheaper than spiral sand washers. However, they meet most sand washing requirements. Considering the sand and gravel composition, the desired production capacity, and the conditions of the factory site will determine which type of sand washer you need. These types of sand washers are also more compact and easy to operate, which makes them an attractive choice.
Cost of a sand washer
The cost of a sand washer depends on its capacity and features. If you need a large capacity washing plant for a large construction site, you might want to consider a high-capacity wash plant. Several types of equipment are available for washing sand from various feeds.
Sand Classifying: Using a hydrocyclone for a sand washer allows you to classify sands down to minus 3/8″ size. Hydrocyclones use water to separate a slurry feed and dewater minus 3/8″. Sand Classifying Tanks are useful for separating lignite, fine rock, and other minerals from a single feed.
Washing launder
The cost of a sand washer depends on the type of sand and stone it is used for. Some machines include an electric motor for the bucket wheel, which rotates slowly with the rotary impellor. The rotary impellor then separates the sand and stone from water by breaking down the impurities on their surface. The clean sand and stone are then discharged from the washing launder.
These modules are ideal for producers with multiple sites, as they can easily be packed up and shipped from one processing location to another without needing to duplicate equipment. Additional modules can be added as needed to create a complete wet processing plant that is flexible enough to meet any production need.
With a shorter lead time than stationary plants, Modular Wash Plants arrive on-site almost fully assembled in containerized modules. The modules are quick to set up and easy to assemble, so you can begin production in a shorter time frame compared with traditional plant construction methods.
Final Words
When combined together or with solutions, you can create an entire wet processing plant to produce various types of aggregate and sand products. Modules can be added or removed as the application requires, providing you with the flexibility to produce the highest quality products from any type of deposit.
