High efficiency large   linear vibrating/vibrator screen

Introduction 
Linear vibrating screen is designed with dual-vibration motor drive.Two synchronous motors are reversely placed so that the exciter generate reverse excitation force, the exciting force generated by eccentric block cancel each other out on the parallel direction of motor axis,and stack together with the perpendicular direction of motor axis, so its trajectory is linear.Linear vibrating screen is suitable for particle size from 0.074 -5 mm,the maximum size should be less than 10mm.
Application:
Linear vibrating sieve is widely used in mining, coal, refractories, metallurgy, building materials and other industries. Mineral linear vibrating screen is usually used for the screening and grading materials in large, middle and small particles.
Advantages

     A.Common advantages and features of our Linear Vibrating Screen
         1.Suitable for rough screening with high capacity.
         2.Long travel distance for materials on the screen surface, high screening efficiency.
         3.Parallel transportation of materials while screening.
         4.Adjustable inclination of screen surface.

     B.Drive and Mounting of Linear Vibrating Screen
         Drive is achieved by electric motor with carden shaft to the drive shaft equipped with twin unbalance adjustable weights where required additional v-belt drive can be provided. The number of exciters is increased according to screen width and two models are available with the exciters arranged above the screen or below depending on application.
 Operation and Maintenance

      A.Maintenance of Vibration Motors of the Linear Vibrating Screen

The Linear Vibrating Screen requires limited preventive maintenance. However, there are a few steps to follow to ensure years of trouble free service. In general, you need to complete a common sense inspection of the structure, vibration motors, etc. on a daily basis. Daily inspection on the screens for wear or holes is needed. If damages occur, repair or replace as necessary. The vibrator motors must be greased with lubricating oil. Over greasing causes overheating of the bearings and this must be avoided. Besides, use only prescribed grease in vibrator motor. If different grease is used, vibrator can be damaged and warranty will be voided. Use only prescribed amount of grease to lubricate vibrator. Too much grease will cause the bearings to overheat and result in premature bearing failure.

      B.Precautions during the Installation of Screening Mesh on Linear Vibrating Screen

The process during installation of screening mesh on linear vibrating screen is very important as it will affect the durability and the operation function of the mesh. Here are the precautions during the installation and choosing of screening mesh:

      1.The coarser the diameter of the screening mesh, the better the screening efficiency. Coarser diameter of screening mesh is preferable as the process during the installation of screening mesh is more tedious.

      2.While cutting the screening mesh, make sure that the width of the screening mesh and the mesh frame is consistent. The length of the screening mesh must exceed 50 to 70 mm compare to the mesh frame.

      3.During the process of installation, make sure that the screening mesh is tightening as this will affect the screening efficiency.

      4.While installing the cleaning mesh device with the bouncing balls, the difficulty of screening efficiency and the size of screening mesh must be consider. 

      5.If there is large quantity of materials and if the size of screening mesh is larger, supporting net should be installed under the screening mesh. This is for supporting purposes by reducing the pressure on the screening mesh. Besides, this will prolong the life span of the screening mesh.

      6.After the mesh frame assemble with the screen box of the vibrating screen, remember to slip the extra part of the screening mesh into the discharge port in order to avoid mixing of materials.

      7.During the installation of the platen, pay attention of the flatness of the platen. Then, use the foam sealing tape to seal it. This is to prevent mixing of materials and to extend the life span of the screening mesh.

      8.After that, conduct the screening test by using some materials. Make sure that the movement of the materials is in linear motion while the machine is working.
