According to the different structure of the casting bearing body, the shot blasting machine
is divided into drum type, chain plate type, rotary table type, trolley type, squirrel cage type and hanging shot blasting machine.
Roller and chain plate shot blasting machines are suitable for cleaning small and medium-sized castings that are not afraid of collision. The roller shot blasting machine turns the casting over and runs forward by relying on the spiral guide bar in the cylinder. The chain plate shot blasting machine makes the casting overturn and run through the movement of the chain plate. Rotary table, trolley and hanging shot blasting machines are used to clean large and medium-sized castings. They are usually equipped with a fixed shot blasting chamber, and the cleaned castings rotate or move in the shot blasting chamber. The shot blasting room is generally equipped with several shot blasting devices, which are installed in different positions and shot from different directions, so as to improve the cleaning efficiency and quality of the shot blasting machine. The hanging shot blasting machine can be equipped with several hooks on the catenary according to the needs of the cleaned castings. During cleaning, the castings are hung on the hooks and turn over automatically while moving forward. The castings shall be loaded and unloaded outside the shot blasting room and cleaned indoors.
According to the working system, it can be divided into intermittent and continuous shot blasting machines
The shot blasting machine
is mainly composed of four parts:
① The shot blasting device usually uses a high-speed rotating impeller to eject the shot in a certain direction under the action of high centrifugal force. In the working process, some shot blasting devices can swing at a certain angle or move up and down.
② Projectile collection, separation and transportation system.
③ The bearing body that enables the casting to continuously run and turn over in the process of shot blasting.
④ Dust removal system.
Sand blasting room: no deep pit (or pit), low capital construction cost and short construction period.
The equipment of shot blasting cleaning machine is mainly composed of shot blasting device, wear-resistant rubber ring belt, winch, lifting, separator, feed conveying, dust remover and cleaning machinery.
