High screening efficiency Roller Screening Machine 520-1280 TPH Throughput


Product Description
As an indispensable equipment in the mine crushing production line, the Roller Screening Machine can screen materials stably and evenly to meet the purpose of screening the size of materials required by customers. The model of this Roller Screening Machine is XCDRS1410, and its throughput is in the range of 520-1280 tons per hour, which is applicable to the crushing production line of medium and large mines.
In order to achieve better screening effect, we recommend that the feed side length of the ore be less than 700 mm, and adjust the gap of the roller shaft to 25-100 mm according to the customer's material demand (after placing the order, communicate with the staff to determine the gap value, which cannot be changed after the production is completed).


Equipment Principle
A roller screening mahcine consists of a series of cylindrical shafts or rollers that are arranged in a parallel configuration. These rollers are equipped with screening elements, such as metal bars or perforated plates, which allow for the passage of particles of a certain size. The material to be sorted, in this case, soil and rocks, is fed onto the rollers and moves along their length due to the rotational motion of the shafts. As the material travels across the rollers, particles smaller than the screening elements pass through, while larger particles are retained and transported to the end of the roller screen.

Introduction to Types of Screening Equipment
The screening equipment mainly uses methods such as rotation, vibration, reciprocating, and swinging to screen the raw materials through the sieve, and classify them into different grades based on particle size, or remove moisture, impurities, etc. for subsequent processing. Screening machinery can be classified into circular vibrating screens, linear vibrating screens, resonance screens, fixed screens, shaft screens, equal thickness screens, cylindrical screens, etc. based on its appearance, screening principles, and field of use.
Resonant screen is a type of vibrating screen, whose natural vibration frequency is consistent with the screen surface (including feeding). This system can fully utilize the inherent frequency of the device to operate in a resonant state, resulting in very low power consumption. However, the structure of the resonance screen is relatively complex, difficult to debug, has a high failure rate, and has many structural strength issues.
The working component of a cylindrical sieve is cylindrical, and its entire sieve rotates around the cylindrical axis. Usually, the main shaft is installed at a small tilt angle. The material enters from one end of the cylinder, granular material passes through the sieve holes of the cylinder, and coarse material flows out from the other end of the cylinder. This screen has the characteristics of low rotational speed, smooth operation, and dynamic balance. But its sieve holes are prone to clogging, screening efficiency is low, operating area is small, and production is low.
The working surface of a roller screen is composed of horizontally arranged rollers. There is a plate on the rotating shaft, and fine materials can pass through the drum or plate. Large pieces of material are transported to the other end through a drum and then sent out from the end. The screen shaft of the drum screen is set at different working angles, and the speed is faster when the material is in a position with a higher working angle of the drum screen; At lower working angles, the transportation of materials will be slower. When two types of materials meet at a certain point on the screen surface, axial movement occurs, achieving uniform distribution of materials on the screen surface and improving screening efficiency.
