Gravel Separator Machine is used for separation, screening and grading of materials such as sand, gravel, etc. It is usually composed of a feeding device, a screening system, a transmission device, a discharge port and a bracket. According to the screening requirements, you can choose sieves with different mesh numbers or aperture sizes. Common specifications include 2 mesh (about 10mm), 4 mesh (about 5mm), 8 mesh (about 2.36mm), etc. There are also sieve holes in millimeters, such as 10mm, 20mm, and 30mm, which can meet the separation requirements of coarse, medium and fine particle sizes. The equipment can be equipped with one or more layers of sieves to achieve secondary or multi-stage screening. It is often used to efficiently grade gravel larger than 30mm, medium-sized crushed stone and small-particle stone powder. Some models also have a dust removal system or a water washing device to effectively remove dust and soil impurities, improve the overall environmental protection performance and the cleanliness of the finished product.

Mobile gravel separators are particularly common and convenient for transfer operations; they also have the characteristics of high efficiency, large processing capacity and convenient operation. For stone sites with a daily output of more than 1,000 tons, heavy-duty gravel separators with double or three-layer screening structures can effectively meet large production needs, and their hourly processing capacity can reach 50-300 tons.

Gravel Separator Machine uses a vibration motor as an excitation source to make the screen box produce linear reciprocating vibration, driving the material to jump forward on the screen surface, thereby realizing the stratified screening of sand and gravel according to particle size. When the equipment is started, the dual vibration motors installed on both sides of the screen body rotate in the opposite direction at the same time, generating a combined force to make the screen box vibrate linearly. After the material enters the screen surface evenly from the feed port, it is thrown up and moves forward under the action of the vibration force. During the process, smaller particles pass through the screen holes and fall into the lower layer, while large particles move forward along the screen surface to the end and are discharged, realizing particle classification.
The screen usually adopts a multi-layer structure. For example, a three-layer screen can divide the material into four particle sizes (such as >30mm, 10–30mm, 5–10mm, <5mm), and can be configured with different "mesh numbers" or opening sizes (such as 4 mesh ≈ 5mm, 8 mesh ≈ 2.36mm) to flexibly meet the needs of different working conditions. The advantages of the linear vibration principle are clear screening trajectory, high screening accuracy, large processing capacity and simple structure, which are suitable for continuous and high-intensity work.

Gravel separator machines are mainly categorized into various types based on their structure and application. Our factory offers banana screens, mining linear screens, linear screens, dewatering screens, mining vibrating screens, and drum screens. Customers can select the appropriate model based on their production needs. Banana screens utilize a variable-angle arc screen surface, offering high screening efficiency and large throughput, suitable for grading large gravel. Mining linear screens and general-purpose linear screens rely on linear vibration to convey materials, providing stable screening and a wide range of applications. Dewatering screens combine screening and dewatering functions, effectively separating mud and water from gravel. Mining vibrating screens feature a robust and durable structure, adaptable to harsh mining conditions. Drum screens screen gravel through a rotating cylinder, reducing clogging and ensuring reliable operation. Various models can be flexibly selected based on gravel size, output, and operating conditions.
