4、Technical Specifications

Two、Technical Requirements

1、Agitator blade's self-rotation and rotation speeds at high and low speeds（See Table 1)

Table 1 The self-rotational and rotational speeds of the agitator blades at high and low speeds should comply withBelowRequirements

2、The operation procedure of the胶砂mixer

2.1 Manual and automatic modes available

2.2 The automatic control program is: low speed for 30 seconds ±1 second, followed by another low speed for 30 seconds ±1 second, while the automatic start is initiated simultaneously.Add SandAdd all within 20s-30s, high speed for 30s±1s, stop for 90s±1s, high speed for 60s±1s。

2.3  Manual control with high, stop, and low speed settings, as well as sand addition function.Button, and automatically interlock.

3、Sand Addition Device

3.1 Completeness: Standard Sand Used for One TestAvailableAll in pot.WillSpatter.

3.2 Sand-adding Device: The cement mortar mixer features a new sand-adding structure, controlled by a stepping motor via program, ensuring a more even sand-adding speed.Control timing is more accurate; the motor can automatically oscillate several times after adding sand to ensure better performance.Higher sand completeness.

4、Blender Pot

4.1 The mixing pot is made of stainless steel.

4.2 Blender Pot Depth: ≈ 180mm.

4.3 Diameter of Mixing Pot: ≈ 200mm, the difference in diameter in the vertical direction should not exceed 0.5mm.

4.4 Blender pot wall thickness: ≈3㎜。

4.5 Magnetic lock structure for mixing pot（Easier to pick up and put away, stable after locking)。

5、Agitator blades

5.1 The agitator blades are made of stainless steel.

5.2 The agitator blade shaft is equipped with an eccentric locking deviceWith rapidLocking DeviceProceedLocking, Locked afterN/AShake.

5.3 Total Width of Mixing Blade: ≈135mm; Effective Length of Mixing Blade: ≈130mm; Width of Mixing Blade Wings: 8mm ± 1mm; Thickness of Mixing Blade Wings: 6mm ± 2mm.

5.4 Blade-to-vessel bottom and side clearance: 3mm ± 1mm.

6、Operation Status

6.1 A prominent sign indicating the direction of the blade rotation is located on the motor head. The blade rotation is clockwise for self-rotation and counterclockwise for revolution.

6.2 The concrete mixer operates with normal sound, pot 1 and agitator bladesN/AVisible vibration phenomena.

7、Insulation properties

7.1 The electrical control of the concrete mixer is stable and reliable, with the overall insulation resistance ≥ 2MΩ.

8、Appearance

8.1 The exterior surface of the concrete mixer shall not be rough or uneven.

8.2 The non-processed surfaces of the concrete mixer should be treated for rust prevention, and the exterior paint should be smooth, even, uniform, and have consistent color tones.

8.3 The processing surface of the concrete mixer's parts must be free from bumps, scratches, and rust spots.

8.4 The concrete sand mixer is equipped with an automatic opening and closing door to prevent dust from flying.

Section 3:Structural Features

1. New sand-adding structure with step motor speed control for precise rotation, driving the sand hopper to uniformly pour sand into the mixing pot. The sand-adding process adheres to the standard规定的 speed through programmed control, ensuring a higher degree of completeness.

2. Magnetic Clamp Stirring Pot Locking Device, uses magnetic attraction to securely lock the stirring pot, making the pot installation easier and more stable, and preventing any shaking during the stirring process.

3、The control mode utilizes an intelligent expert setting system, allowing users to customize the test process control methods according to their specific requirements and automatically complete the tests. It can achieve continuous loading and maintain load under any load. The test process is free of shocks and vibrations, offering excellent reading stability. The test process can be simulated and reproduced.

4. RetainerAsh灰DoorAdoptedAutomatic sliding doorMethod: Easily switch the door on and off with the button.。

5、AgitatorThe pot stand is equipped with a stepping motor and ball screw to achieve automatic lifting and lowering, ensuring precise positioning.

6. Spindle adoptedServo motor flexible transmission，Complementing planetary gear setup to reduceEquipment noise, extended service life。
