Product Description

high-performance tumble belt shot blasting machine

This machine utilizes a high-speed rotating impeller to propel abrasive shot onto workpieces that are continuously tumbling inside the drum, achieving the purpose of cleaning. It is suitable for descaling, removing oxide layers, and surface peening of small castings, forgings, stampings, and other parts from various industries, and is particularly well-suited for the surface cleaning and strengthening of parts not susceptible to impact damage.

Warning! Do not clean workpieces that are at high temperature or have burrs/flash, as this will damage the crawler belt.

This model of shot blasting machine is a replacement for traditional rotary barrel blasters. It is a cleaning device with effective cleaning performance, compact structure, low noise, and good completeness. It features the following characteristics:

Wear-resistant rubber crawler belt, which reduces impact damage to workpieces and lowers machine noise.
The machine employs a high-efficiency centrifugal shot blasting unit, known for its long service life, simple structure, and low failure rate.

An air-separation type classifier is used, providing excellent separation efficiency and high productivity, thereby reducing wear on consumable parts (such as the impeller blades).

A bag-type dust collector is installed, with dust emission concentrations below national standards, significantly improving the working environment for operators.

After cleaning is complete, the workpieces can be automatically discharged by reversing the rotation of the crawler belt.

A loading mechanism is equipped, and users can optionally select a discharging mechanism to further reduce the labor intensity for workers.

Key Configurations

Main performance characteristics:

The machine uses a high-speed rotating impeller to throw the abrasive to the continuously turned workpiece in the chamber to achieve the purpose of cleaning. It is suitable for small castings, forgings, stamping parts in various industries for shot peening, removal of oxide and surface strengthening, especially for the cleaning and strengthening of parts that are not afraid of collision.

    This type of shot blasting machine is a replacement of the shot blasting drum, which is a cleaning equipment with good cleaning effect, compact structure, low noise and good complete set. It has the following characteristics:

·The wear-resistant rubber belt reduces the collision and damage to the workpiece and reduces the noise of the machine.

·The machine adopts Q034 type direct-connected centrifugal blast wheel, which has the characteristics of long service life, simple structure and low failure rate.

·The use of air separator has good separation effect and high productivity, and reduces the wear of wear-resistant parts (such as blast wheel blade).

·Dust collector, dust emission concentration is lower than the standard stipulated by the state, improve the working environment of workers;

·After the workpiece is cleaned, the track can be reversed to realize automatic discharge.
