What’s The Stone Washing Machine?
Each piece of equipment has a different title, including professional terms in the industry and everyday terms. As well as mining machinery. The stone washing machine is also called the sand washing machine, mainly used to remove impurities (such as dust) from sand products. Because it is mostly washed with water, it is called a stone washing machine. Below we will introduce the different stone washing machines.
Classification of stone washing machine equipment
● Spiral washer
The spiral stone washing machine(spiral washer) is used for the desliming and screening operations of many sand and gravel used in construction sites, sand and gravel factories, prefabricated plants, and hydropower construction sites. It can also use for ore sorting operations. The spiral stone washing machine uses a screw to propel the stone to separate the stone from the water and soil, so the stone is quite clean after processing, and it is one of the more popular stone washing equipment at present.
The Spiral stone washing machine is a new type of high-efficiency equipment developed and produced using advanced foreign technology and combined with domestic stone washing machine equipment. It mainly uses the spiral washer for washing away impurities and soil in granular materials in highways, railways, bridges, tunnels, hydropower stations, construction sites, urban construction, and other industries. The spiral washer is professional equipment for cleaning stone materials, suitable for fine-grained and coarse-grained material operations of different specifications.
The spiral stone washing machine is composed of a central shaft driven by a motor, a drum frame, a rotary thread groove, and a metal screen. The main shaft and the drum frame connect with steel bars. The drum frame’s inner edge fixes with a rotary thread groove, and the outer edge is wrapped with a metal screen. The two water pipes penetrate the circular spiral cavity of the rotary screw groove.
The spiral thread groove has a certain stroke length from the beginning to the end. When the stroke completes, the cleaned stone has reached or exceeded the national and ministerial standards. The mud and water washed from the stone directly leak from the screen and flow into the sedimentation tank for sedimentation. The sedimented water can be pumped out again and recycled. The conveyor belt machine, the screening drum, and the screening washing drum are sequentially connected to the towable trolley, which can work together. There are a pair of meshing gears at both ends of the screen. The gears are an integral shaft (the shaft is the motor’s drive shaft). A couple of meshing bevel gears are installed on the gear shaft equipped with a pulley. The belt drives the pulley on the transmission shaft, and the motor drives the whole machine. Four tugs support the cleaning cylinder, the motor drives the reducer, and the large and small gears drive the cleaning cylinder to rotate at a low speed. The aggregates containing mud and stone powder are fed from the feeding port into the rotating drum. The wear-resistant rubber lining plate installed at a certain angle in the cleaned drum is continuously lifted and dropped and moves from the feeding end to the discharging end. During the process, it is circulated and washed by the flushing water in the forward or reverse direction. The cleaned aggregate is sieved and dehydrated by the discharge end drum screen and then discharged. Wastewater containing sludge flows through a perforated baffle at the discharge or feed end.
● Drum/Roller stone washing machine
A Cylinder stone washing machine is also called a drum washing machine or roller stone washing machine. Four tugs support the cleaning cylinder, the motor drives the reducer, and the large and small gears drive the cleaning cylinder to rotate at a low speed. Feed the mud and stone powder aggregate from the feeding port into the rotating drum. The wear-resistant rubber lining plate installed with a certain angle in the cleaned drum is continuously lifted and dropped and moves from the feeding end to the discharging end. During the process, it is circulated and washed by flushing water in the forward or reverse direction. The cleaned aggregate is screened and dehydrated by the discharge end drum screen and discharged. Wastewater containing sludge flows through a perforated baffle at the discharge or feed end.
● Wheel bucket stone washing machine
Wheel bucket stone washing machine is new washing equipment in recent years. It can wash sand and stones and has a wide range of uses and social demands. It widely uses the wheel bucket washing machine for the washing, classification, and impurity removal of metallurgy, building materials, hydropower, and other industries. This kind of washing machine applies to the washing and separating of fine-grained and coarse-grained materials. It is especially suitable for building sand and road sand. The sand/stone washing machine has a reasonable structure, convenient maintenance, large processing capacity, low power consumption, and high cleaning. The novel sealing structure, fully enclosed oil bath transmission device, and adjustable overflow weir plate ensure this series of products’ high efficiency and durability, good cleaning and dehydration effects, and stable fine-grained products.
The motor and the reducer drive the wheel bucket stone/sand washing machine to drive the impeller in the water tank to rotate continuously in the water tank to stir and turn the sand or slag particles tank in the water. Elutriation and make the water-receiving material dehydrated in the impeller and discharged.
● Vibrating stone washing machine
The vibrating stone washing machine is mainly used to clean the slime-containing ore before the concrete mixing process is implemented and improve the beneficiation index of the subsequent process. We commonly use it for ore washing of manganese ore, iron ore, limestone, tungsten ore, tin ore, silica sand ore, and other minerals. According to the mud content, particle size, and washing difficulty of the ore, it can select a double spiral, trough, or barrel screen washing machine. This vibrating stone washing machine also often cleans sand and gravel at construction sites, power stations, and other sites. It is suitable for desliming sand and stone.
The above are the most commonly used stone washing machines. If you want to know how to select suitable stone washing machines for your project, please contact our engineer for help.
