Customized Mountain Sand Washing Plant & Equipment

Mountain sand is the sand excavated on the surface of sedimentary landforms, which has characteristics of high mud content, iron oxide content, and organic content, and is generally not used in high-grade concrete. Mountain sand divides into coarse sand, medium sand, and fine sand. Large rocks extracted from mountain sand require many processes to become mountain sand, and there are many types of raw materials. Design a reasonable production plan based on equipment cost, production scale, operation, and site. With the increasing demand for building materials, mining and processing equipment for mountain sand is also becoming increasingly popular.

2. It uses hydraulics for adjusting the space of the toothed roller, and centralized lubrication of the toothed roller bearings. It has the advantage of tooth shape optimization design, selection of tensile and shear forces for crushing, low consumption, and uniform grain production.
3.  The roller crusher has the advantages of small volume, high crushing ratio, low noise, simple structure, convenient maintenance, high efficiency, the uniform particle size of crushed materials, low over-crushing rate, convenient daily maintenance, sensitive overload protection, and high reliability.

 

Mountain Sand Washing Machine

1. Wheel Sand Washing Machine

The electric motor drives the impeller to rotate slowly after being decelerated by a V-belt, reducer, and gear. Sand and gravel enter through the feed chute and rolling and grinding below the impeller to remove impurities that cover the surface of the gravels and destroy the water vapor that covers the sand. At the same time, add water to form a strong water flow, remove impurities from time to time and foreign objects with small specific gravity, and discharge them from the overflow tank. Use a blade to remove clean sand and gravel, and finally pour the gravels from the rotating impeller into the discharge chute to achieve the cleaning effect of the gravels.

• Features:

① Less loss of fine sand

The wheel sand washing machine has less loss of fine sand during the cleaning process, and the grayscale and fineness modulus of the cleaned sand meet the standard requirements for building sand.

② Simple structure with the low failure rate

The wheel sand washing machine has a simple structure, with the transmission part isolated from water and sand, and almost no other wear parts except the screen. Effectively avoiding bearing failures caused by water and sand, its failure rate is much lower than the commonly used sand-washing equipment in the current market. Easy daily maintenance and short downtime.

2. Spiral Sand Washing Machine

It is generally inclined when installing a spiral sand washing machine. When it is working, the screw starts to rotate under the action of the electric motor. The sand and gravel enter the cleaning tank from the feed tank, flip and collide with each other under the drive of the screw, and then exit the impurities on the surface of the sand and gravel, breaking the water vapor layer that covers the sand particles to facilitate dehydration. Under the drive of the screw and the action of its gravity, the sand and gravel move from high to low, Clean sand and gravel entering the discharge chute through rotation, completing the cleaning function of the sand and gravel.

• Features:

① The structure is simple and reasonable, with high processing capacity and low loss during the sand washing process.

② The processing capacity is large, the production cost is low, and the single machine output can reach up to 180 tons/hour, basically meeting the sand washing requirement of our customers.

3. Trommel Screen Washing Machine

working principle:

The drum-type trommel screening washing machine consists of four pulleys, with an electric motor driving the reducer, a big gear, and a small gear driving the cleaning cylinder to rotate at low speed. Mud and stone powder are fed from the feeding port and enter the drum. The wear-resistant rubber lining plate with a certain angle in the cleaning cylinder will be cycled multiple times and washed with forward or reverse flushing water. The cleaned aggregate will be screened and sent to the discharge end, and then dehydrated. The wastewater containing sludge will flow through a porous baffle at the discharge or feed end.

• Features:

The Trommel screen sand washing machine requires a large amount of water and also has a large processing capacity. Reusing the cleaned sewage can achieve the effect of water conservation.
