The advent of sifter machine has greatly saved labor costs and production costs, so how to select sifter machine accessories? How to improve the sifter machine really achieved high quality, high efficiency production demand?
Sifter machine typically consists of vibrating motor, screen, grid, bearing, bouncing ball and other device, most of which are vulnerable parts, no matter which damage will affect the screening effect and efficiency of the equipment, these parts are replaced more frequently, which requires sifter machine users to select suitable spare sifter machine accessories:
1: Vibrating Motor
The core device of sifter machine. It also called exciter. The magnitude of the exciting force depends on the size of the sifter machine, the characteristics of the material and the handling capacity. The motor also is basis of the weight and capacity of sifter machine. Control of exciting force is vital part:
Over-big exciting force will cause cracks of the body.
Over-small exciting force will not reach the ideal handle capacity. And the annoying blockage problem will arise.
2: Mesh
The most indispensable component is the mesh part. It is the part contact with materials directly. The quality and safe performance both the characteristics customer most considered.The mesh commonly pided into 316L/316/304 stainless steel. You can select the quality for what your material are. They all meet the hygienic standards of food grade. Clean and disinfect easily by its smooth surfaces.
What are the different between these material quality?
3: Bearing
Bearing is the support point of vibration motor. It is one of the most important parts in sifter machine. Its main function is to support the mechanical rotating body, reduce friction coefficient and rotary accuracy in the operation of vibration screen.
Therefore, the following points should be paid attention to when selecting bearings:
1. Check whether there are cracks, impurities and corrosion inside and outside the bearing.
2. Whether there are murmurs or not when rotating, and whether there are muddy oil stains on the surface;
3. Check whether the clearance of the bearing is within the error range.
4: Spring
Spring is an important part of vibration reduction system. There are three kinds of spring: steel spring, rubber spring and composite spring. In the process of selecting spring, the corresponding selection is usually made according to the vibration load, working environment and working condition of vibration equipment.
Composite spring is an elastic body composed of steel spring and rubber, which integrates the advantages of metal spring and rubber spring and remove the disadvantages of those, such as the steel springs are easily deformed. Its shape and mechanical performance are stable, it can withstand loads and large deformation, and it has good effect of vibration isolation and noise reduction. It works in stable resonance zone time.
5: Bounce ball
The bouncing ball of the vibrating screen is installed between the sub-net and the parent net of the screen. During the working process of the vibrating screen machine, the bouncing ball circulates and bounces back and forth to impact the materials adhering to the sub-net, so as to increase the penetration rate of the materials, thereby effectively avoiding the blockage of the screen net by the materials and improving the screening output.
The common size of a bounce ball is about Ф20-60. And the material quality are rubber, silicone, polyurethane.
Rubber balls are round and clear. It has the characteristics of heat resistance, acid resistance, alkali resistance, corrosion resistance, wear resistance and oil resistance.Usually used for screening different materials without special requirements such as hygiene.
Silicone rubber has excellent heat resistance, cold resistance, dielectric property, ozone resistance and atmospheric aging resistance. The outstanding performance of silicone rubber is that it can be used at a wide temperature, even if the temperature reaches 250 degrees. Because of its non-toxic, non-polluting, tasteless, no side effects, it is very suitable for food, medicine,chemical industry with special requirements(Including other seals, such as seals should also choose silicone material).
General silicone balls has poor oil and solvent resistance, so silicone rubber is not suitable for ordinary conditions, but it is very suitable for many specific occasions.
Polyurethane balls is more wear-resistant, which is characterized by high hardness, good strength, high elasticity, high wear resistance, tear resistance, aging resistance, ozone resistance, radiation resistance and good conductivity, etc. It is incomparable with ordinary rubber.
