I. Product introduction

TD0506-1 Planetary cement and mortar mixer is manufactured by Hebei Tianqi Xingzi Testing Equipment Co., LTD. According to the industry standard JTG of the Ministry of Transport, PRC Developed and produced T0506-2005 "Cement mortar Strength Test Method (ISO Method)" in "Test Regulations for Highway Cement and Cement Concrete".

Cement mortar mixer used to determine the strength of cement mortar and other test methods specified in this standard.

Second, structure and type

The planetary sand mixer consists of a sand mixing pot, a blade and the corresponding mechanism. The stirring pot can be moved freely, but it can be easily fixed on the pot seat, and stirring will not be obvious shaking and rotation; The stirring blade is fan-shaped, rotating clockwise and rotating counterclockwise around the pot when stirring, and has high and low speed, belonging to the planetary mixer.

Three, technical parameters

4.1 Rotation and revolution speeds of stirring blades at high and low speeds shall meet the requirements in Table 1:

Table 1 Rotation and revolution speed of stirred blade at high speed and low speed

Autobiography, r/min revolution, r/min

Low to 140 + 5 to 62 + 5

285 plus or minus 10 to 125 + 10

4.2 The working procedure of the sand mixer is dynamic and automatic.

The automatic control program is as follows: low speed 30s±1s, then low speed 30s±1s, and at the same time automatically start adding sand and finish all adding within 20s~30s; high speed 30s±1s, stop 90s±1s, high speed 60s±1s.

Manual control with high, stop, low three speed and sand function control twist, and automatic interlock.

4.3 The standard sand used in a test shall all enter the pot and shall not be splashed outside.

4.4 stirring pot

4.4.1 Stirring pot shall be resistant to rust. The shape and basic dimensions of the stirring pot are shown in Figure 1.

4.4.2 Stirring pot depth: 180mm±2mm.

4.4.3 Inner diameter of stirring pot: 202mm±1mm.

4.4.4 Wall thickness of stirring pot: 1.5mm±0.1mm.

4.5 Stirring blade

4.5.1 Stirring blades are made of cast steel or non-embroidered steel. The shape and basic size of stirring blades are shown in Figure 2.

4.5.2 The axial diameter of stirring blade is Φ27.0mm±0.5mm; The thread connecting with the stirring blade drive shaft is M18×1.5 ~ 6H; The diameter of the positioning hole is mm, and the depth is ≥18mm.

4.5.3 Total length of stirring blade: 198mm±1mm;

Effective stirring length: 130mm±2mm;

Total width of stirring blade: 135.0mm~135.5mm;

Stirring blade wing width: 8mm±1mm;

Stirring blade wing thickness: 5mm±1mm.

4.6 The working gap between stirring blades and the bottom of the pot and the wall of the pot: 3mm±1mm.

4.7 The direction of revolution of the stirring blade is marked in the conspicuous position of the nose. The rotation direction of stirring blade is clockwise, and the rotation direction is counterclockwise.

4.8 The sound of the mortar mixer is normal during operation, and the pot and stirring blade shall not have obvious shaking phenomenon.

4.9 The electrical control of the sand mixer is stable and reliable, and the insulation resistance of the machine is ≥2MΩ.

4.10 The outer surface of the sand mixer shall not be rough or uneven, and there shall be no bumps or depressions not specified in the drawing.

4.11 The non-processed surface of the sand mixer shall be treated with rust prevention, and the paint on the outer surface shall be smooth, smooth, uniform and consistent in color.

4.12 The machining surface of the parts of the sand mixer shall not be bruised, scratched and rusted.
