Maize can not be sieved without vibrating screen

 Vibrating screen should be adopted in the beginning of the removal of impurities during the production of maize starch,in order to ensure a safe production of raw materials,so the removal of impurities is very necessary, maize raw materials contain a variety of impurities, dust, organic impurities, inorganic impurities. The general design will be 3 screen decks, the first deck screen surface with an aperturesize of 17-20mm hole, aimed to eliminate over sized impurity; second deck screen surface with an aperturesize of 12-15mm hole, used to remove impurities of medium size, third deck screen surface with an aperturesize of 2mm hole, used to remove minor impurities.
Advantages are high precision, large capacity, simple structure, low energy consumption, low noise, long service life, good sealing, no dust overflow in the screening process, and reduce the pollution of the dust, the screening efficiency is up to 98. It is very suitable for the screening and classification of powdery and granular materials, applicable to dry powder material chemical industry, food, medicine, metallurgy, plastics, glass, building materials, food, fertilizer, abrasives, ceramics etc.

Small part with large effect : Vibrating Screen damper

Do you know Circular Vibrating Screen damper?it’s a device which limits vibrating screen horizontal vibration.
May be you feel puzzled,is there any vibration in the horizontal direction?The answer is no In theory, but the practice has proved that it exists, the reasons are as follows:
(1) The distribution of material on the screen mesh is uneven. 
If the material is uneven,it can lead to the uneven force for screen box ,thus vibrating error appears.
(2) Installation error.
The Circular Vibrating Screen needs horizontal installation,but in the process of installation, the error will inevitably occur, resulting in a height of four supports occur small deviation, but the small deviation will be amplified by the vibration exciter, thus it will result in greater vibration deviation.
(3) the stress error of the spring.

► Introduction and working principle：
Rotary vibrating screen is designed as a high-precision screening machinery. Round vibrating sieve is composed of vertical motor,and eccentric weight installed at two ends.We can produce horizontal, vertical, inclined motions by adjusting the upper and lower eccentric weight.Diameter can be ranged from 400mm to 2000mm, with single or multiple screening decks.
► Working Principle：

XZ Rotary Vibrating Screen is a vertical-motor system, with eccentric hammers being installed on top and bottom of the machine, where the motor acts as the vibratory source. The direction of the eccentric hammers may change its rotational mode either in horizontal, vertical and inclined movement onto the sieving screener surface. The trajectories of the materials on the sieving machine can be change by adjusting the phase angle on both top and bottom parts.

 Running Track of Rotary Vibrating Screen

► Application :
    Powder rotary vibrating screen is widely used in many kind of industries
    Food industry: sugar, salt, alkali, glucose powder, monosodium glutamate, soy milk, yeast, wheat starch, wheat flour, rice flour, skimmed milk powder, fruit juice, dehydrated vegetables, thick, pineapple juice, soy sauce, corn starch.
    Chemical industry: pigment, medicine powder, oil, rubber, plastic, epoxy resin, PVC resin, polyethylene powder, vinyl chloride resin, aggregate grains,cosmetics.
    Ceramic industry: glass powder, refractory material, silica sand, spray soil particles, mud, grinding materials, nano brick materials, artificial graphite, kaolin, lime hydrate, mica, aluminum oxide, calcium carbonate Oxygen, diamond powder
    Metallurgy mining industry: lead oxide, zinc powder, aluminum powder, iron powder.
Pollution treatment: waste water, waste oil, pig dried urine, dyeing wastewater.
Other industries: carbon black, pearl powder, light calcium, additive, etc..
 

rotary vibrating screen

► Features
-Layers can be up to five layers
-Fully enclosed design,continuous operation,small volume and low noise
-Self-cleaning device(bouncing balls),avoiding blockage, mesh size can reach to 500 mesh ( 0.028 mm)
-High precision, high efficiency, powder, granule and mucus are applicable
► Advantage : 

 1.Low energy consumption, low noise, 

 2.High screening accuracy, large capacity, simple structure. 

 3.Fully enclosed structure, good sealing, prevent dust spillover, automatic discharge, more suitable for assembly line work.  

 4.Screen body parts are used copper plate and section welded together (part group between body for bolt connection) overall stiffness is good, strong and reliable.  

 5.Unique design of screen structure, convenient and quickly to change screen (only 3 to 5 minutes); And her mother screen fully supporting the fine screen, so fine screen can be long life, so as to reduce the consumables cost of the fine screen; In addition this design allows to using all kinds of screen (nylon, special dragon, PP network).

What should we notice when maintain the vibrating screen in summer?

In summer, excess temperature is a hidden danger of daily operation for vibrating screen, generally speaking, working requirements of the environment temperature is not more than 40 ℃, so during the daily operation of vibrating screen, what we should concern about is not only the process of production, but also the degree of temperature that the vibrating screen can bear.

For the outdoor working conditions, a anti-sunshine net or cover should be set up for the vibrating screen.

Long-time sun exposure not only make the machine easy to get aging, but also cause the vibrating screen can not work normally due to the high temperature which will affect the screening efficiency and quality, it will even lead to a serious component damage, such as the damage of vibration motor.

For the indoor working condition or vibrating screen works in an ore processing plant, please pay attention to the adjustment of the indoor temperature, as well as the ventilation and the permeability, generally, a good working temperature is not more than 40 ℃.
