M&Y grain cleaner


The M&Y grain cleaner equipment system consist of one screening equipment and one recycling winde clean equipment, it is have one perfect grain sizing (grading) and cleaning result , this equipment could remove over 95% of the straw ,bran and broken grain from wheat, compare the normal grain cleaner screeing equipment, the capacity of M&Y grain cleaner equipment system could over 120 TPH.

Advantage of Long Amplitude Stroke

The advantage of long amplitude stroke and low frequency of gyratory screen

The main feature of the rectangular gyratory screening is long amplitude stroke and low frequency.
The amplitude stroke is between 50mm-90mm, and the frequency is between 185-300rpm, there are rubber ball under the screen mesh, the long amplitude could offer strong force to the rubber ball, so the ball could have enough force to clean the mesh.

The material feature factor affect the screening

When we select the gyratory screener, the material characteristics is the important factor which affect the screening 
efficiency and capacity , please consider following data carefully:
1. Material bulk density
2. Material size,such as max particle size, mins particle size and particle size distribution 
3. The moisture of the bulk material
4. Particle shape
5. Temperature
6. Flowability

Vibratory Screen Cleaning Methods

                                                          Vibratory Screen Cleaning Methods
 Supplied by Mega Young Screening Technology

The screen blinding is one important problem during screening, lets discussing the reasons and solution first

General
Screen blinding always happends when the screen mesh openings are blocked or closed by the  material  which  is  being screened. Near size particles become trapped or build up on the wires effectively blocking the screen openings preventing further material from passing through the screen. And some  blinding  because  the   material  features  such  misture   and stickiness,  and some because there are  too many fabric, This is  a common screening problem which is easily fixed  with screen cleaning devices. following will review the most common methods of screen deblinding.

1.BALL TRAYS
Rubber or other spring balls are the second most utilized screen cleaning method, but can only be used for dry screening. The rubber balls are generally 20mm-50mm diameter and  are  supported by a  second  coarser  mesh  two  inches  below  the classifying screen mesh. Higher vertical separator motion is required to activate the ball  cleaning action  because the balls must be thrown up against the bottom of  the  screen, in this  case ,the  rectangular gyratory screener have long  stroke  and strong force which could let ball jump.

2.SLIDERS
The most common self cleaning device is the “SLIDER”. Slider Rings are loose rings which slide directly beneath the screen surface on a slider support surface, normally a perforated metal plate. The rings are bounced vertically into the screen mesh by the vertical motion of the separator as they travel radially around the screen. The sliders are activated by the motion of the separator with out additional driving force

3.SANDWICH SCREENS
Sandwich screens are made by bonding a classifying mesh to the top of the screen tension ring and a coarser support screen mesh to the bottom of the ring. This creates a sandwich with screen cleaning devices floating between meshes. This sandwich construction improves cleaning action, decreases maintenance costs, and decreases noise levels.

4.TOP SIDE ROTARY BRUSHES
The top side rotary brushes are exceptional for clearing fibrous materials which tend to mat on top of the screen and block the mesh openings. The rotary brushes move around the screen diameter propelled by the  vibratory  motion  of the  separator, no additional driving motors are required. The brushes ball up the fibrous mat above the screen to expose screen  the  openings, the fiber balls are then discharged from the top of the screen and out the spout.

5.WATER SPRAYS
Water  sprays  clear  screen  mesh  openings, help  eject  solids, and  keep  slurries  from  drying out  and  building up  inside separators. Another spray advantage is there is no contamination from slider, ball, or brush  materials. The  disadvantages  of liquid sprays are cost and potential dilution of products.

6.Metal percussion

This is method is mainly adopt on the rotary screener, the Metal  hammer  rotate  follow  with the  rotary  screen  drum, and  the hammer knock on drum casing periodly.

Recycling Gyratory Separation Screen System for Testing Screening



In order to get the accurate data for rectangular gyratory screening&separation capacity calculation and aperture selection, we set up one circular (recycling) screening system in our workshop, this system include one gyraotry screeners, three belt conveyors and one material silo, for some important data, we can test screening for over 2 hours, mainwheal , we can get the proper screening capacity and screen mesh aperture size and the best screening and separation result.
Our gyratory screens has been used in following industry successful: Grain, fertilizer, sugar, salt, sand, wooden pellets etc
So welcome you to our company for visit for discussing the screening equipment business, we believe we can offer you the proper screening solution and screening equipment with our experience.
