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.

 

How to select the gyratory vibrating screen

Gyratory vibrating screen is generally used for granule, powder etc fine screening, such as urea, silicon carbide, activated carbon, silica sand, salt, sugar, plastics etc industries.
Features of gyratory screen:
1. It can be customized to be 1~3 lyers, and the sieve mesh size can be indicated;
2. Generally,Screen mesh material is stainless steel, it also can be selected according to the customer’s requirements;
3. There are self-cleaning device (bouncing ball) under the screen mesh, to avoid blocking during running;
4. The gyratory screen box can be open-type, also can be enclosed model, sealing and dustproof;
5. The main screen body generally is hanging installed, it also can be designed to be seated type accordingly;
6. The screen mesh width can be selected from 1200~2000mm, screen mesh length can selected from 3000~4000mm. Special design also can be achieved.
In order to give you a better project solution, please kindly supply the following technical requirements:
1. Do you have any installation space limit?___
2. How to feed material into the gyratory screen:___?
3. The required capacity ____t/h
4. Separated material name _____
5. Material density ____ t/m3;
6. Material particle size distribution percentage___%
7. Material temperature ____℃;
8. How many layers do you need ? or how many kinds range particle size material will you want to separate out?
9. If need to match the feeding device or discharging belt conveyor, please kindly send us the production line layout sketch, we will help you design the details accordingly.

Technological reformation of Gyratory Screen Mesh required by New Zealand clients

With the purpose of achieving the demands of our clients who ordered 4 sets of gyratory screen used for screening glass, our screen mesh technique gets a further improvement.

We designed air hole buckles embedded at the edge of screen mesh which not only improve the sealing performance, but also can  achieve the fixation function to prolong the life span of gyratory screen mesh.

A support mesh is added under the fine screen mesh which not only increase the elasticity , but also play a role that prevents material from piercing through the screen mesh. PK Machinery has great confidence that our client will satisfy with it.

What Screen is Used in the Feed Industry--the Gyratory Screen

At present, most feed manufacturers need to sieve and grade the powder material ,granular feed, and the intermediate products after secondary crushing. The quality and output of the feed products are directly affected by the classification and the performance of the equipment. What screen is commonly used in the feed industry? The answer is the gyratory screen. It is widely used in feed industry due to its simple structure, large output, convenient maintenance, low noise.
Under the inertia force, gyratory screen sieve box moves back and forth, driving the screen surface shaking periodically, and forcing feed material on the screen surface jumps along with the screen box, the material which is less than sieve aperture will be discharged from the outlet after continuous rolling and jumping movement, then screening operations complete.

Gyratory screen is a new type of high efficiency swing type linear screening equipment ,and also called square swing sieve, it can completely solve the screening accuracy and processing output contradiction of general vibration screening machine, see the following characteristics:
1.Reasonable design, mature technology, easy installation and maintenance, wide application scope;
2.High screening efficiency , precision and processing capacity;
3.Unique design, convenient screen mesh replacing, high utilization rate, long service life;
4.Good screen mesh self-cleaning effect is good, low noise;
5.Good sealing effect, energy saving and environmental protection.

Besides, gyratory screen can be used in chemical, metallurgy, ceramics, non-ferrous metals, food, abrasive, mining and other industries in the accurate screening and grading process. Specific application materials, for example, chemical industry: chemical fertilizer, resin, melamine, soda ash ; Food industry :starch, salt, sugar, milk powder and other; metallurgy, non non-ferrous metals, nonferrous metal, magnetic materials.
