Structures and Features for Three types of Rotary Vibrating Screen Net Rack
Rotary vibrating screen is designed as a high-precision screening machine it is widely used for sugar, salt, wheat flour, rice flour, pigment, medicine powder, ceramic, silica sand, metallurgy zinc powder, aluminum powder, iron powder, calcium powder etc.
The net rack is the important component of rotary vibrating screen, here we will introduce the structures and features of three common net racks for rotary vibrating screen.
1.U-shaped net rack
It belongs to the very commonly used model of rotary vibrating screen, first use the pressurized tooling to fix the thick wire diameter of screen mesh in the U-shaped groove, this layer is called meshed net, then the working net is tiled above the meshed net and clamped it. The advantage of this type of net rack is the replacement of working net in a faster rate, the framework of meshed net supports the working net to ensure the flatness of screen surface and prevent the impulsive force of material causing damage of working net, at the same time also will avoid the damage of working net due to the strike of bouncing ball that on the screen plate. The only disadvantage of this type of net rack is the overlapping part of meshed net and working net, which will influence the screen area.

2.Snap fastener net rack
Rotary vibrating screen has two flanges: convex and concave. The concave flange is welded inside the screen frame, while the convex flange is a movable component, the screen mesh is placed between two flanges and locked up with the screw, the screen surface will tension naturally. Generally, this net rack structure is designed for the screen mesh with 12 mesh-30 mesh.

3.Dual A net rack
It also known as the single net with dual clamp net rack or light weight net rack structure. Rotary vibrating screenwith this net rack is using two ring shaped circular hoop fix tension screen mesh. The main advantage of this type net rack is higher screening rate.

Installation and operation notes of rotary valve
Rotary valve is also known as discharge valve, it is mainly is used in power plants, cement plants, chemical plants etc. and dust removal industry, packing machine and professional mixing & conveying systems. Rotary valve is used for quantitative feeding and air lock when conveying dry powder material. It can also used for the lower hopper of dust collector and air preheater. It is an ideal accessory in conveying, discharging and dosing system due to simple structure, stable performance and easy maintenance.
Installation notes
1. The rotary valve must be kept clean, especially the inner body of main casing .
2.Check all fasteners to ensure the connection is reliable, the machine (including motor) is well earth grounded.
3. The upper and lower flange under of rotary valve must be fixed firmly, to make the whole machine placed inhorizontality at the same time
4.Check the wiring of motor to ensure it is able to start.
Operation notes
1.Pay attention that if motor is over heat when start up the power supply ,you must stop and inspect it, so as not to affect normal operation of the gearmotor.
2.Gearmotor must be operated as per the operating manual and the gearmotor rotating direction must rotate as per the arrow direction as shown.
3.If powder leakage phenomenon is found on the shaft, please tighten the packing gland bolts at both ends.
4.During operation , check heating circumstance of bearing, general bearing temperature rising shall not be over 60 ℃.
5.During operation, if you find abnormal vibration, please stop the machine and exclude the abnormal phenomenon.
6.If there is bolt looseness in the process of operation, please tighten the bolt.
