Different Sand Screening Machines

Date: Dec. 07, 2020

The sand screening machine is a sand and gravel separation equipment suitable for rivers and coal yards. It is composed of a fuel tank, drum screen, reducer, conveyor belt, electric motor, and so on. The structure is simple, economical, and easy to operate. It is mainly divided into two types: drum sand screening machine and vibrating sand screening machine.

trommel screen

There are four types of drum screening machines: 20, 30, 50, and 80. These models are divided into standard version and heavy version, and can also be customized according to the actual needs of customers.

Due to the large output, the vibrating screen sand machine usually has three types: 30, 50, and 80. This kind of sand screen machine is equipped with up to four layers of screens, which can achieve multi-stage screening effects at the same time, and the price is also more expensive than the drum screen sand machine.

1. Different appearance

The shape of the vibrating screen sand machine is rectangular, and it adopts a unique pressing net structure design, which will not mix the materials, and the screening accuracy is adjustable.

The main structure of the drum sand screening machine is a sieve cylinder, which is composed of several circular screens. The whole machine is inclined to the ground. The outside is sealed by an isolation cover, which can effectively prevent external dust from entering or material spilling and polluting the environment.

2. Different working principles

The vibrating screen sand machine is driven by a single vibration motor or a double vibration motor. When the two vibrating motors rotate synchronously in opposite directions, the exciting force generated by the eccentric force cancels each other in the direction parallel to the axis of the motor and is perpendicular to the motor, and the direction of the shaft is stacked as a resultant force, so the trajectory of the screening machine is a straight line. The shaft of the vibrating motor has an inclination angle relative to the surface of the screen. Under the combined action of the exciting force and the gravity of the material, the material is thrown onto the screen surface and moves forward in a straight line, so that the small material particle screen can pass through the screen hole. Fall to the next level. The materials with holes are left on the screen surface for screening and sorting of materials.

In the process of sieving sand, the equipment will not vibrate. Instead, the motor and reducer rotate the drum through bearings. The material in the drum will change due to the rotation of the drum and the size of the sieve so that the sand can be successfully filtered out.

3. Different applicable materials

The vibrating screen sand machine is a new type of screening equipment, which can be widely used in food, refractory materials, light industry, chemical industry, fertilizer, plastics, abrasives, and other industries. It is mainly used to screen large-particle materials or coarse-particle powder materials.

As a mining screening equipment, drum sand screening machine is mainly used for sand and gravel separation.

4. Different prices

The trommel sieve sand machine is usually cheaper than the vibrating sieve sand machine, and the same model of the sieve sand machine is more expensive than the trommel sand sieve machine. This is because the vibrating sand screening machine is heavy, and the drum sand screening machine is divided into ordinary type and heavy-duty.
