Upgrade and modernization, cost reduction and efficiency improvement-our company’s two shot blasting machine upgrade and modernization projects in Chengdu and Hunan were successfully delivered and accepted

The shot blasting machine in use cannot meet the current use requirements due to initial design, disrepair and requirements adjustment. Effective upgrading and modernization is the most cost-effective measure to meet it. As a professional comprehensive service provider for surface treatment, we are in closely contact with customers and provide timely equipment production and technical modernization services. The following are the recent successful cases that we have helped users with shot blasting machine upgrading and modernization.

★ Chengdu Project: Upgrade the elevator and rotary table of rotary table shot blasting machine.

★ Project background: The service life of shot blasting machine is long and the damage is serious, so it needs to be remade.

According to the use needs of customers, we have agreed on the transformation scheme with customers:

Redesign of elevator:

Change the structure of hoist for abrasives recycle to avoid wear of the hoist casing, the overall service life of the hoist casing is improved;

Produce new rotary table:

✘ Defects of the original guard:

◆ Casting material;

◆ Frequent rupture;

◆ High replacement frequency

✔ Advantages of our new rotary table:

◆ The top guard plate is made of high wear-resistant manganese steel plate;

◆ Avoid the disadvantage of crushing the guard plate under pressure;

◆ The service life is increased by 3-5 times;

◆ The maintenance cost is greatly reduced.

After updating the service life of the two parts is 4-5 times higher than that before!

★ Hunan Projects:Replacing a blast wheel and improving the current situation of large dust in the workshop.

★ Project background: one blast wheel cannot work, there is a large amount of dust in the workshop, and the damage frequency of the dust remover is very high. These problems must be solved.

As for the replacement of blast wheel, after discussion of both parties, we decided to replace with a TD380 high-efficiency blast wheel for customer:

This blast wheel has the following advantages:

◆ It is a single disc shot blasting wheel;

◆ Equipped with 4 pieces of high wear-resistant tool steel blades specially made by our company, the frequent fracture of the original cast blades is avoided, the shot blasting efficiency is increased by 15% – 20%, energy saving and consumption reduction is achieved;

◆ Make the best use of motor power, which is efficient and power-saving;

◆ The orientation sleeve is adjustable, and the positioning of the blasting hot zone is accurate, which is suitable for all kinds of workpieces;

◆ Smooth supply of abrasives;

◆ High abrasives flow;

◆ The installation method is simple and easy to replace, saving time and labor.

After installation, the shot blasting effect has been significantly improved!

For the problem of large amount of dust in the workshop, we suggest customer to add magnetic separator.

 

The following improvements can be achieved by adding magnetic separator::

1、 It can effectively separate the molding sand and dust in the steel shot, and the separation rate is as high as 99%, reducing the amount of dust in the shot during the machine operation;

2、The reduction of molding sand improves the service life of spare parts, in which the service life of blades is prolonged by 4-5 times;

3、The replacement frequency and cost of spare parts are reduced;

4、Prolong the service life of dust collector bag;

5、The workshop environment is effectively improved.
