2、Operation procedure of the concrete 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 to 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, plus sanding function controlButtonAnd interlocks automatically.
3、Sand-adding device
3.1 Completeness: Standard sand used in a single testAvailableAll into the pot, please.WillSplatter.
3.2 Sand-adding Device: The cement mortar mixer uses a new sand-adding structure, controlled by a stepping motor via program to regulate the sand-adding process, resulting in a more even sand-adding speed.More accurate timing control, the motor can automatically vibrate several times after adding sand.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 locking structure for mixing pot（Easier to pick up and place; no movement once locked.。
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 device.With rapidLocking DeviceProceedLocking, After lockingNo content provided.Shake.
5.3 Total width of agitator blades: ≈135mm; Effective length of agitator: ≈130mm; Blade wing width: 8mm ± 1mm; Blade wing thickness: 6mm ± 2mm.
5.4 Blade to pot bottom and side clearance: 3mm ± 1mm.
6、Operating Status
6.1 A prominent sign indicating the blade rotation direction is marked on the engine head. The self-rotation direction of the mixing blades is clockwise, and the rotation direction is counterclockwise.
6.2 The sand mortar mixer operates with normal sound, pot 1 and mixing bladesN/AVisible vibration phenomenon.
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 outer surface of the concrete mixer should not be rough and uneven.
8.2 The non-processed surfaces of the concrete mixer should be treated with anti-rust; the paint on the outer surface 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-driven variable-speed rotation controlled by a program, which drives the sand hopper to rotate and evenly pour the sand into the mixing pot. The sand-adding process is fully programmable to meet the standard sand-adding speed, ensuring higher completeness.
2. Magnetic Clamp Lock for Stirring Pot, utilizes magnetic attraction to securely lock the stirring pot. This makes the installation of the stirring pot easier and more stable, preventing any movement or shaking during the stirring process.
3、The control mode utilizes an intelligent expert setting system, allowing users to customize the test process control methods based on their specific requirements and automate the testing. It can achieve continuous loading and maintain load under any load condition. The test process is free from shocks and vibrations, offering excellent reading stability. The test process can be simulated and replayed.
4. BarrierGrayDoorAdoptedAutomatic Sliding DoorMethod: Use the button to easily open and close the door.。
5、StirrerThe pot stand features an stepper motor and ball screw for automatic lifting and lowering, ensuring precise positioning.
6. Main shaft is utilizedServo Motor Soft Drive，Coupled with a planetary gear unit to reduceEquipment noise, extended service life。
