4、Technical Specifications

Two、Technical Specifications

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

Table 1 The self-rotation and revolution speeds of the mixing blades should comply with when operating at high and low speeds.BelowRequirements

2、Operation procedure of the asphalt sand mixer

2.1 Available in manual and automatic modes

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.ButtonAnd interlocks automatically.

3、Sand Adding Device

3.1 Completeness: Standard sand used in a single testAvailableAll into the pot.WillSpill-over.

3.2 Sanding Device: The cement mortar mixer utilizes a new sand-adding structure, controlled by a programmable stepper motor to regulate the sand-adding hopper, ensuring a more uniform sand-adding speed.The timing control is more accurate, and after adding sand, the motor can automatically oscillate several times.Higher sand completeness.

4、Blender Pot

4.1 The mixing pot is made of stainless steel.

4.2 Mixing 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 Mixing Pot Wall Thickness: ≈3㎜。

4.5 Magnetic suction lock structure for mixing pot（Easier to pick up and place; locks securely without any movement.。

5、Agitator Blade

5.1 The mixing blades are made of stainless steel.

5.2 The agitator blade shaft is equipped with an eccentric locking deviceWith rapidLocking deviceProceedLocking, after lockingN/AShake.

5.3 Total width of mixing blades: ≈135mm; Effective length of mixing blades: ≈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 label on the engine head indicates the direction of the blade rotation. The blade's self-rotation is clockwise, while the orbital rotation is counterclockwise.

6.2 The sand cement mixer operates with normal sound, pot 1 and agitator bladesN/ANoticeable oscillation.

7、Insulation properties

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

8、Appearance

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

8.2 All non-processed surfaces of the concrete mixer should be treated to prevent rust, and the paint on the outer surface should be flat, smooth, even, 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 cement 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 programmable stepper motor variable-speed rotation, driving the sand hopper to rotate and evenly pour the sand slurry into the mixing pot. The sand-adding process can be programmed to strictly adhere to the standard规定的 sand-adding speed, ensuring higher completeness.

2. Magnetic Clamp Locking Device for Stirring Pots, utilizing magnetic attraction to securely lock the stirring pot. This design makes the installation of the stirring pot easier and more stable, preventing any movement during the stirring process.

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

4. BarrierAsh灰DoorAdoptAutomatic Swing DoorMethod: Use buttons to easily open and close the door.。

5、StirThe pot stand features an stepper motor and ball screw for automatic lifting and lowering, ensuring precise positioning.

6. Spindle designServo Motor Soft Drive，Complementing the planetary gear assembly to reduceEquipment noise, extended service life。
