Linear vibrating screen (straight screen sieve) is stable and reliable, low consumption, low noise, long life, vibration stability, high screening efficiency.

Introduction to Linear Shaker

Linear vibrating screen is mine, mineral processing, coal preparation, building materials, thermal power plants, chemical and other industrial sectors of the important screening equipment.

Linear vibrating screen for coal preparation, mineral processing, building materials, hydropower, chemical industry, medium and fine-grained materials for dry and wet screening and dehydration, disassembly, desliming. The sieve machine technical parameters of advanced, high vibration strength, processing capacity, high screening efficiency. The use of dual motor self-synchronization directly through the coupling drag the vibrator, simple structure, easy maintenance, smooth operation, low noise, long service life.

Performance characteristics of vibrating screen

  • 1, the use of block eccentricity as the exciting force, strong excitement.
  • 2, vibrating screen sieve beams and sieve box with high strength bolts, no welding.
  • 3, vibrating screen sieve structure is simple, easy maintenance.
  • 4, vibrating screen with tire coupling, flexible connection, smooth operation.

Structural part of vibration screening machine and its working principle

The selection function of the vibrating screen is mainly done by the vertical air sieve. According to the aerodynamic characteristics of the seed, the speed of the air flow is adjusted according to the critical speed of the seed and the impurity, and the purpose of separation is achieved. Was sucked into the sedimentation chamber concentrated discharge, the better seed through the air screen into the vibrating screen. Vibration screening two layers of sieve up and down, with three kinds of exports, can be mixed, small mixed and selected seeds discharged, special requirements can be installed three sieve, four kinds of exports, and more for grading.

The vibrating screen consists of hopper, frame, transmission mechanism, fan, duct and other five parts, the rack feet with four wheels, easy to move; screen and rack with split structure, easy to replace a variety of different mesh Of the net screen.

Vibrating screen works:

First place the machine in a horizontal position, turn on the power, start the work switch, to ensure that the motor clockwise operation to show the machine into the correct working condition. And then the selected material into the hopper, according to the size of the material particles to adjust the bottom of the hopper at the bottom of the material so that the material evenly into the upper screen; also make the upper part of the screen cylinder fan to the screen discharge side of the correct air ; The lower end of the fan outlet can also be directly connected to the bag to accept the light in the light of waste.

The lower part of the vibrating screen has four bearings which are fixed in the channel in the frame to reciprocate. The upper coarse sieve of the sieve is the large particle impurities in the cleaning material, and the lower sieve is the small particle impurities in the cleaning material.

The side of the selection machine through the activities of the connecting rod and the motor driven crankshaft or eccentric wheel coordination work to complete the selection of the whole process of impurity removal.

Vibrating screen structure is novel and compact, smooth operation, compact and durable, high screening efficiency. Thus greatly reducing the labor intensity, improve the efficiency; is the food and oil safety warehousing, and can pest control, mildew indispensable selection of screening equipment.

How is the vibrating screen properly selected?

Vibrating screen in the selection should pay attention to the workplace and the size of the machine, equipment, material requirements and other objective factors.

Due to different screening materials, the requirements of the shaker material is also different, the food industry and screening and food-related materials, the machine material should be selected stainless steel or contact materials, stainless steel, clean and sanitary, so as not to affect the screening quality. If the material for the chemical industry, metallurgical and other industries raw materials, contact with the material part of the choice of general steel material, the cost is also lower than the stainless steel material, and does not affect the use.

Vibrating screen trajectory is a straight line, so most of the time in the manufacture, the shape of a rectangular, one to meet the material in the linear movement of the length of the operation, the second is the shape of the rectangle can make the largest area of ​​screening, Accuracy. Therefore, in the choice of vibration screening equipment must first consider whether the workplace is allowed, it is worth noting that the outline of the vibrating screen is the actual size of the area.

Due to site restrictions and other reasons, can be made in the outlet of the article, in general, the mouth can be made forward forward, downward, tilt down three conditions, in order to save the site can choose the outlet Stretch down The shape of the discharge port can also be shaped according to actual needs, for example, round, square and other shapes in order to facilitate the connection with the next process.
