Volumetric mass (weight) sample small ore mass (weight) samples of the original ore should generally be collected in the borehole or tunnel. The sampling volume is not less than 60 cm 3 , and the ore with uneven structure should be appropriately increased in volume. In the detailed exploration stage, the number of samples shall be no less than 30 for each major ore type or grade in the ore body. Each sample is tested for both S and other estimated resources/reserves and affects the mass (body weight) of the components to investigate the relationship between volumetric mass (weight) and grade. The small volumetric mass (weight) of powdered pyrite ore can be collected from various prospecting projects according to its distribution. The sampling volume is generally not less than 200 cm 3 . If iron ore powder sulfur development, during the exploration phase, to add one to three large volume mass (weight) sample. The sampling volume is not less than 0.125 m 3 . At the same time, a small volume mass (weight) sample and a chemical sample were used to demonstrate the sampling method and representativeness of the large volume mass (weight) sample. The humidity is measured while collecting the volumetric mass (weight) of the powdered pyrite ore, and the season or climatic conditions of the sampling are recorded.
Product introduction
Steel Bending Machine, one of steel reinforcement processing machinery.
The working mechanism is a horizontal working disk rotating on the vertical axis. The steel bar is placed in the dotted line position in the diagram. The supporting shaft is fixed on the machine tool.
For bending steel bars of various diameters, there are several holes on the work plate to insert the bending pin shaft, and the center pin shaft of different diameters can be replaced accordingly.
Advantages of characteristics
Applicable to all kinds of round steel, carbon steel, screw steel.
It has strong operability, high working efficiency, convenient Angle adjustment and neat bending
Operation procedures of steel bending machine:
1. Check whether the mechanical performance is good, keep the working table and bending machine surface level;
And prepare various spindle tool blocks.
2. According to the requirements of the diameter of steel bar and bending machine, the core shaft, forming shaft, iron shaft or variable structure shall be installed. The core shaft diameter shall be 2.5 times of the diameter of steel bar.
Check the core shaft, block and turntable shall be free of damage and crack, and the protective cover shall be tightly fixed and reliable, and the operation shall not be performed until it is confirmed that the air machine is running normally.
Iv. During the operation, insert the bend end of the steel bar into the clearance provided by the turntable for fixation, and fix the other end close to the fuselage and press it with your hand to check the fuselage fixation.
The side that actually holds the steel bar can be moved.
It is strictly forbidden to change the spindle, change the Angle, adjust the speed and so on.
When bending steel reinforcement, it is strictly forbidden to process steel reinforcement diameter, root number and mechanical speed beyond the mechanical specification.
When bending high hardness or low alloy steel bars, the maximum limit diameter shall be changed according to the mechanical nameplate, and the corresponding mandrel shall be replaced.
8. It is strictly forbidden to stand in the working radius of the bending steel bar and the unfixed side of the fuselage.
Curved semi - finished products should be stacked neatly, curved hooks should not face up.
When the turntable is turned, it must be done after it has stopped.
X. completion of operation, cleaning of site, maintenance of machinery, power off lock box.
