Shot Blasting Machine Classification Introduction

Shot blasting machine classification introduction

Shot blasting machine can be divided into drum type, chain plate type, turntable type, trolley type, squirrel cage type and hanging type according to the structure of casting body.

Drum and chain plate shot blasting machine is suitable for cleaning small and medium castings that are not afraid of collision. The drum type shot blasting machine relies on the spiral guide rod in the cylinder to rotate the casting forward. The chain plate shot blasting machine rotates and runs the casting through the movement of the chain plate. The cleaning of large and medium-sized castings adopts the rotary disc type, trolley type, hanging type shot blasting machine, usually a fixed shot blasting room, and the cleaned castings rotate or move in the shot blasting room. The shot blasting room is generally provided with multiple shot blasting machines, which are respectively installed in different positions and shot in different directions to improve the cleaning efficiency and quality of the shot blasting machine. According to the needs of cleaning castings, the hanging shot blasting machine can be provided with multiple hooks on the hanging chain. When cleaning, the casting is hung on the hook, and it can rotate when moving forward. Castings are loaded and unloaded outside the shot blasting room and cleaned indoors.

According to different working systems, it can be divided into intermittent shot blasting machine and continuous shot blasting machine.

Shot blasting machine is mainly composed of four parts: ① Shot blasting machine generally adopts high-speed rotating impeller, and blasts shot in a certain direction under the action of high centrifugal force. In the process of work, some shot blasting machines can swing or move up and down at a certain angle.

② Projectile collection, separation and transportation system.

③ A bearing body that enables continuous operation and rotation of the casting during the shot blasting process.

④ Dust removal system.

Sand blasting room: no deep pits (or pits) are needed, the capital construction cost is low, and the construction period is short.

Shot blasting machine equipment is mainly composed of shot blasting machine, wear-resistant tape, winch, lifting device, separator, feed conveyor, dust collector, cleaning machine, etc.

Drum-type drum shot blasting machine mainly uses high-speed rotating impeller to throw the shot blast onto the drum-type continuous rotating workpiece to achieve the purpose of cleaning the workpiece, which belongs to the category of casting machinery. It is suitable for sand cleaning, derusting, descaling and surface strengthening of castings and forgings under 15kg in various industries. The drum type shot blasting machine is suitable for cleaning various castings and forgings that are not afraid of collision and scratches. It is an ideal equipment for cleaning residual sand and oxide scale on the surface of the workpiece in a small heat treatment workshop. It is mainly composed of rollers, separators, shot blasting machines, elevators, gear motors, etc., etc.
