Drum Tester

Drum tester

The sinter and pellet drum tester produced by our company is a special equipment for measuring the drum index and anti-wear index of sinter and pellet, which is used to test the impact resistance and wear resistance of sinter and pellet. The drum tester is designed and manufactured in accordance with the requirements of the national standard GB8209-94 "Method for measuring the drum strength of Sinter and pellet".

Effective diameter: ∅1000mm; Effective width: 500mm

Speed: 25±1r/min; Sample loading: 15kg (detailed parameters see the page below: Technical parameters)

Applicable materials: sinter, pellets

Drum testing machine product introduction

The drum testing machine produced by our company is mainly composed of frame, drum, driving device, counting device and so on.

The frame is welded from section steel and mainly plays a supporting role, and all components are installed on the frame.

Roller is the main part of the equipment, it is made of steel roll, through the two ends of the support shaft, with vertical seat bearings placed on the support, forming a free turning of a cylinder. The barrel body is provided with a material opening that can be opened and locked and sealed, and a lifting plate is welded inside the barrel.

The driving device is composed of a reducer, a coupling, etc. To drive the drum to meet the requirements of the constant speed of operation, the deceleration system is also equipped with manual adjustment device, easy to discharge.

The counting device is connected with the supporting half-shaft of one end of the drum, and the work is to feedback the speed, record the number of rotation revolutions, and control the equipment to stop automatically after reaching the required number of revolutions.

Outstanding advantage

1. The frame and barrel are welded and rolled by high-quality steel and steel plates, which are wear-resistant and durable and have a long life.

2, the motor is an electromagnetic braking variable frequency motor, which can control the speed to meet the standard requirements, on the other hand, it can make the equipment stop quickly when it is stopped.

3, equipped with counting device, automatic record speed, automatic stop, high degree of equipment automation.

4, compact structure, smooth operation, low failure rate, simple maintenance operation.

Working principle

The material is placed in the drum, and when the drum is running, the material rolls along with it. Under the action of the lifting plate, the sintering or pellets are taken to a high place. After exceeding the drum 90°, the material begins to fall down freely. In the friction and collision with the drum, and the friction and collision between the material, the sintering or pellets are broken, after reaching the preset number, the drum stops rotating, the material is discharged from the feed port, and a set test period is completed. Then the impact resistance and wear resistance of sintered and pelleted ore are calculated according to the screening weight.
