Five Categories of Shot Blasting Machines

There are five categories of China shot blasting machines: road surface shot blasting machines, tumble shot blasting machines, hook type  shot blasting machines, table shot blasting machines, internal steel tube shot blasting machines.
Here's a detailed introduction of the characteristics of various kinds of shot blasting machines.

1. Road surface shot blasting machines
Shot blasting machines for road surface are mainly used to solve the defects of the concrete surface treatment. It can remove laitance and impurities of concrete surfaces at one time, and can have the coarsen treatment of the concrete surface, which brings the uniform roughness of surface. This greatly improves the adhesive strength of waterproof layers and concrete base layers, so that the waterproof layer and the bridge deck can be combined better and the crack of the concrete can be fully exposed at the same time, which is a prevention solution. Automatic reverse blowing dust collectors can clean each filter element through air blew back by the compressor at regular intervals. Then, it will be cleaned through the airflow of the assorted cleaner inside the machine. The abrasive material and the cleaned impurity will be recycled respectively, and the abrasive material can be reused. Each shot blasting machine is equipped with a dust collector so that the construction can be dust-free and pollution-free, which can both improve efficiency and protect the environment.
   
Advantages
Shot blasting machines for road surface can be used in the surface treatment of the waterproof base of concrete bridges, the surface coarsen treatment of the pavement overlay, cleaning of the sign line of road, bridge and the steel box girder, improvements of anti-slide performance. Also, it can greatly improve the roughness and texture depth. The uniform roughness will not destroy the original surface structure and integrity. The entire process of construction is dust-free and impurities are completely recycled.

2. Tumble shot blasting machines
Tumble shot blasting machines are is applied for surface cleaning and strengthening of large and medium sized production parts. When the parts to be cleaned is less than 200kg, this machine can be used alone or used as a supporting facility. Applied ranges: die castings, precision castings, the cleaning of precision forgings, mass finishing, removing heat treatment parts, castings, surface oxidation of castings, and intensification of spring, rust removal and pretreatment of fasteners.

Advantages
Tumble shot blasting machines can be applied for various productions such as large and medium-sized workpieces, rust cleaning or shot blasting of the surface. The workpieces to be cleaned usually are the main parts and heat treatment parts with weight of less than 150kg. The machine can be used alone or used as a supporting facility. It is suitable for the cleaning, rust removal, scale removal and surface strengthening of small castings, forgings, stamping parts, gears, springs and other parts, especially of fragile parts. 

3. Hook type shot blasting machines
As the standard mode of shot blasting machines, the maximum carrying capacity of the hook type shot blasting machine is 10000 kg. A hook type shot blasting machine has very high efficiency and good flexibility. It is an ideal cleaning and strengthening facility, which is mainly used for surface treatment of various media, large castings, forgings, weldments, and heat treatment parts, including fragile and irregularly shaped workpieces.

Advantages:
With the advantages of large shot blasting, high cleaning efficiency, large space, compact structures and no special requirements on the shape and structure of the cleaning piece, a hook shot blasting machine can serve several purposes. It is applied for sand cleaning, rust removal, scale removal and surface reinforcement of the castings and forgings less than 15kg of various industries. This machine is equipped with a special set of dust device, so the place of installation is free from the ventilation pipe workshop and it has good sanitary conditions.

4. Table shot blasting machines
The table shot blasting machine is mainly used for volume surface cleaning of small and medium sized workpieces. It is suitable for the engine connecting rod, gear, diaphragm spring , etc. It is widely used in the casting and automobile manufacturing industries. It has several characteristics of high production efficiency, good sealing performance, compact structure, convenient loading and unloading parts, high technical content, etc.

Advantages
The table shot blasting machine is mainly used for the removal of surfaces' sand, rust, oxide skin, dirt, etc., which can restore the surface color of the metal workpiece, eliminate the internal stress, improve the anti-fatigue performance, increase the film adhesion, and ultimately achieve the goal of improving the surface and internal quality.

5. Internal and External steel tube shot blasting machines
An internal and external steel tube shot blasting machine is a new type of net wall shot blast cleaning machine combined with the shot blasting technology to clean the inner wall of the cylinder.

It uses compressed air as its power and utilizes the kinetic energy of accelerating projectile to shoot the cylinder wall. When the cylinder located in the gun room, the gun will automatically insert into the respective bottle and the spray gun will move up and down in the cavity. Then it will complete the full range of cleaning. Inside and outside wall shot blasting machine is the selected type of the cylinder industry.

Advantages
An internal and external steel tube shot blasting machine is mainly used for architecture, bridge and other industries. It is used for rust removal of the large I-shaped steel, H beam and surface. It has advantages of large shot blasting, high efficiency, rapid blade replacement, overall replacement performance and easy maintenance.
