Product introduction

The screw screen shaft is an important part of the screw screen. It is composed of screw and screw bar. When the screw screen is started, the screw rotates, and the material entering the screen surface is pushed forward by the screw bar on the screw rod, and the product under the screen is obtained through the screen hole designed between the screw bar or groove and the screw groove or bar on the adjacent screw.

Product advantages

The spiral shaft is the direct screening mechanism of spiral screen materials, with strong structure and wear resistance. It does not block the screen hole when handling wet sticky coal, and has high screening efficiency. Because the linear velocity of the spiral shaft in the tangent direction on both sides of the screen hole is opposite, there is no material crushing.

Type selection notice

The material can be sorted out according to the shape and hardness of the subsequent material screening machine. The screw pitch and diameter determine the size of the screen, which can be selected from the size range of 10-300 mm, and the rotation number of each screw shaft can be automatically adjusted according to the material composition and humidity. An anti blocking and anti winding automatic cleaning structure is arranged between the screw shafts.
When the screw screen shaft is used in the screw screen equipment, the treatment capacity is determined by the screen surface area. Because the length of the screw screen surface is a certain value, the width of the expanded screen surface determines the size of the treatment capacity. The screen width can be selected according to the user's capacity.

Model description

The screw screen shaft is usually used on the screw screen. The following is the explanation of the model selection when the screw screen shaft is used in the screw screen equipment.
 
   Screw shaft of screw screen
 
1. Specification of standard series model of screw screen
The standard spiral screen models can be divided into 10 categories according to the sieve aperture: 8mm, 10mm, 13mm, 16mm, 20mm, 25mm, 40mm, 50mm, 60 and 80mm; according to the unfolding screen width, it can be divided into three categories: 2.5m, 2M and 1.5m; according to the number of segments, it can be divided into two sections, three sections, four sections and five sections, which are combined to form the standard series of spiral screens. The meaning of the model is as follows:
 
 Screen surface 16mm screw
 
2. Description of screw screen combination screen series preparation
In order to further simplify the classification process, save a lot of building area, reduce the number of equipment, and save the investment of the plant, according to the requirements of the product specifications of the coal preparation plant, the standard series units can be used for combination, and the classification can be carried out on one sieve machine for many times, so as to obtain several products of different specifications and form the combined screen series.
In order to ensure high screening efficiency, the mesh size of the second stage unit screen surface must be the same as that of the first stage unit. Since the material entering the third stage unit is relatively less, and it is easy to penetrate the screen and make full use of the screen surface, starting from the third stage unit, each unit can set different sizes of screen holes for combination, and can also obtain higher screening efficiency. In this way, the material can be gradually graded from small to large on a sieve machine. Example of model meaning:
 50 mm screw on screen surface

Product assurance

Common standard product series
1. Mesh size: 8,10,13,16,20,25,40,50,60,80mm
2. Treatment capacity: less than 16mm mesh: ≤ 500t / h
The mesh size of 20-50mm is ≤ 600-1200t / h
The mesh size is less than or equal to 2000m

Product maintenance

During the operation of the screw shaft, the abrasion of the spiral blade surface is fast, the shaft diameter is smaller, and the screen surface clearance can not meet the requirements of coal quality. Therefore, it is decided to repair the old spiral shaft by surfacing welding.
First of all, we can turn the screw shaft on the top of it, and then we can make two horizontal shafts. After satisfaction, the inner layer is overlaid with J502 electrode. After reaching a certain thickness, kb899 spiral hardfacing welding wire is used to overlay a 2mm thick wear-resistant layer on it. The specification of spiral hardfacing welding wire is 1.6mm, and the hardness after surfacing is HRC ≥ 60. After each 200 mm welding, the slag is removed with a small hammer, and the internal welding stress is eliminated by knocking at the same time. In order to prevent the deformation of the shaft beyond the limit after welding, the symmetrical welding method is adopted. Finally, it is verified on the lathe that the bending amount should not be greater than 1 mm.
After re assembly, the wear resistance of the shaft is greatly improved. The service life of the repaired shaft is more than 5 months longer than that of the new one. After the replacement of the whole screw screen, the whole production needs are completely met.
Sl-u series spiral screen is a high price product. It is difficult to purchase the screw shaft and the cost of replacing the new shaft is high. However, using kb899 spiral hardfacing welding wire has the advantages of simple equipment, low cost and easy operation. For each shaft to be repaired, the material cost is only more than 300 yuan, and the purchase cost can be saved by more than 1000 yuan. Therefore, it saves a lot of equipment maintenance costs for enterprises, and has the value of popularization and use.
