Section 1 Factors Affecting Stone Processing Performance

1. Process content: sawing, fixed thickness (milling), surface processing (grinding, polishing, machine planing, fire, hammering, axe, sandblasting, pickling...), cutting, milling, edging, pouring Angle, drilling, slotting, repairing, optimization processing...

2. Factors affecting the processing performance of stone

1. Rock type, mineral composition and content:

(1) The difference in the cutting process parameters between granite and marble, the difference in grinding and polishing materials; (2) the difference in the fire effect between granite and gabbro, basalt and horn rock

(3) Influence of rock structure: coarse grain structure is easy to collapse, and strip structure is easy to break...

(4) The influence of the quartz content on the sawing efficiency...;

(5) Effect of flaky minerals on grinding and polishing

(6) The influence of the composition of the cement in the sedimentary rock on the sawing wear rate, P63 Table 1, Sample 2 in Table 2

2. The magnitude and direction of cutting force

The results showed that:

(1) The cutting force in the horizontal direction when sawing stone is much smaller than the cutting force in the vertical direction

(2) The saw blade wear rate has a completely consistent relationship with the vertical cutting force.

3. Processing equipment and tools

Third, the processing technology

Table 4.1-3 Classification of stone processing technology

Table 4.1-4 Process parameters of diamond circular saw blade sawing granite

Table 3 and Table 4 compare the technical performance of the equipment when purchasing equipment.

4. Comprehensive influencing factors of stone sawability

The empirical formula for the comprehensive assessment is:

Y=27.77-0.168B-0.12C-0.10D

Where: the wear resistance of the Y-saw blade;

Abrasiveness of B-rock;

Shore hardness of C-rock;

The percentage of D-quartz volume.

The above formula shows that the abrasiveness of the stone, the Shore hardness and the content of quartz in the stone all affect the sawability of the stone. Among the three, the abrasiveness of the stone has the greatest influence on the sawability of the stone (for example, the blade material) Sawing with the ocean red).

4 advantages: P76

a. The structure and installation foundation of the sawing machine are relatively simple, the auxiliary equipment is small, and the floor space of the workshop can be reduced by 1/2~2/3;

b. High sawing efficiency, sawing medium-hard granite plates, sawing 250m2 a day, equivalent to the efficiency of two large frame saws with 120 saw blades each;

c. Easy to operate, high precision of sawing, multi-rope diamond bead saw can quickly change the thickness of processed sheet;

d. The sawing surface of the sheet is flat, and the possibility of the steel sand residue being embedded in the sawing surface of the sheet is eliminated, so that the grinding and polishing time is reduced by 20%;

e. The sawing noise is small and the working environment is good;

f. Low energy consumption, about 30% lower power consumption compared to framed sand saws;

g. Consumable materials are greatly reduced, and environmental pollution is small. The frame saw consumes 3kg of steel grit, 1.5kg of saw blade and 2kg of lime per sawing of granitic granite slab, while the diamond wire saw consumes only 0.01kg of diamond rope. It is roughly estimated that the use of frame saws will require the disposal of 325,000 kilograms of waste mortar per year, which is conceivable for the seriousness of environmental pollution. Taking granite slabs with an annual output of 50,000 m2 as an example, the waste slag produced by the diamond wire saw is only about 1.5% of the frame type sand saw, and the waste slag has a single component and convenient external treatment. Therefore, the diamond wire saw is an environmentally friendly mechanical device for sawing stone slabs.

3. The engineering materials should be selected according to the required quantity, the material yield of the blocks, and the qualified rate of the products in the process. Under the premise of ensuring the amount of the project, the amount of excess processing should be minimized to avoid waste.

4. According to the size of the product, select the block with the appropriate geometrical size, so as to avoid excessive margin in the length and height direction of the block, so that the utilization rate of the block is the highest and the yield is improved.

5. When loading, the large surface of the block should be parallel to the sawing surface to ensure that the pattern of the plate is consistent, and has good mechanical properties, and can improve the sawing efficiency.

6. When loading the cargo, the bottom must be provided with a skid, and the skid must be perpendicular to the sawing direction. The cross section of the skid should be no less than 20×15cm to ensure that the skid can withstand the pressure of the block; the length of the skid should be substantially equal to the width of the trolley.

(2) Structure: (illustration)

(3) Analysis of the force of the saw blade: The calculation method can be found in P122～123.

(4) Points of use:

1 Select the appropriate block height according to the width of the remaining blade

2 Adjust the tension of the hydraulic tensioner according to the cross-sectional area of the remaining saw blade so that the saw blade can be tensioned without breaking the saw blade.

3 Use a different width saw blade to reduce saw blade waste.

example:

It is known that the width of the saw blade with a height of 1 m per sawing wears 18 mm, and the thickness wears 0.25 mm. The wear of the saw blade is assumed to be uniform. If the hydraulic tensioner causes each saw blade to receive a tensile force of 55000 N, the tensile strength of the saw blade is 750 MPa. When the width of the saw blade is 65mm and the thickness is 3.5mm, please calculate the amount of material that can be sawed by this saw blade. How to adjust the hydraulic tensioner if you want to cut the stone with a height of 1.50m?

(Set the root strength of the saw blade to 0.5% of the tensile strength) 10%

(1) The root strength of the saw blade σp=750×0.5=375 Mpa

(2) The limit cross-sectional area when the saw blade is broken A=F/σp=55000/375=146.67mm2

(3) Set the saw blade to cut Xm high blocks, then:

(65-18X) (3.5-0.25X) = 146.67

X1=1.087 X2=16.524 (not intent)

(4) After cutting the stone with a height of 1.50m, the cross-sectional area of the saw blade is:

(65-18×1.5) (3.5-0.25×1.5)=118.75mm2

(5) Saw blade tension F=σp×A=375×118.75=44531.25N

(3) Example:

It is known that when using a pendulum sand saw to cut a diorite with a specific gravity of 2.73, each sawing 1 square meter of shredded steel is 2.45kg, and the width of the saw is 7.6mm. Please calculate the 1m2 of each saw. How much lime can keep the mortar at its best? Looking for lime steel sand coefficient?

(1) Weight of stone powder produced by sawing 1m2 wool board: 0.0076×2.73×1000=20.748kg

(2) The amount of lime to be added for sawing 1m2 wool board: 20.748×5.56/32.39=3.56kg

(3) K=3.56/2.45=1.45 (ie 1.45kg lime must be added for every 1kg of steel sand added)

(5) Performance of the abrasive tool and configuration of the abrasive article number

2. The configuration of the grinding tool number on each grinding head of the continuous mill

(1) Abrasive number and abrasive particle size: P132 Table 5.3-8

(2) Calculation method

1 Determine the abrasive particle size a1 a1=R2 on the first grinding head according to the roughness of the board

2 Determine the particle size of the abrasive in the last fine grinding block based on the glossiness of the polishing plate.

The finishing gloss is 55, the abrasive particle size should be 0.013, the grinding tool number is 1200, and the polishing can reach 85 degrees.

The finishing gloss is 60, the abrasive particle size should be 0.010, the grinding tool number is 1500, and the polishing can reach 90 degrees.

The finish gloss is 65, the abrasive grain size should be 0.009, the abrasive number is 1800, and the polishing can reach 95 degrees.

3 Calculate the equivalence coefficient Q

4 Calculate the abrasive grain size on other grinding heads

An = a n-1Q

(3) Example questions

The granite continuous plate mill with a 16-grinding head is used to grind a granite plate with a roughness of 0.95 mm. The gloss of the plate after grinding and polishing is required to reach 90 degrees. Please calculate the particle size of the abrasive used in each grinding head on the mill. (Set: use 3 grinding heads for polishing) 8%

(1) Particle size of the abrasive on the first grinding head:

11=R2=0.952=0.9025

(2) The particle size of the abrasive on the last polishing head:

Since the gloss of the polishing plate is 90 degrees, the gloss of the final polishing is 60 degrees, and the grain size of the abrasive on the 13th grinding head is α13=0.01.

(3) The equal ratio coefficient of the abrasive grain size on each grinding head:

(4) Abrasive grain size on each grinding head:

11=0.9025 (mm)

22=α1·Q=0.9025×0.6871=0.6201(mm)

33=α2×Q=0.6201×0.6871=0.4261(mm)

44=α3×Q=0.4261×0.6871=0.2928(mm)

55=α4×Q=0.2928×0.6871=0.2012(mm)

66=0.1383

...

3. Grinding process elements

According to the concept of "equivalent cutting thickness" proposed by the International Machinery Production Engineering Research Organization (CIRP), it can be expressed as follows:

In the formula:

A- can be considered as the thickness of the chips cut from the stone at a certain speed;

t - depth of cut;

The moving speed of the V1-grinding disc relative to the stone;

V2- grinding disc speed.

The above formula shows that to improve the grinding quality, the gloss should be reduced by A; if the grinding efficiency is to be improved, A should be increased. Therefore, when coarse grinding, the grinding disc pressure should be increased (ie, increase t), while the grinding disc rotation speed is reduced (ie, V2 is reduced), and the moving speed of the grinding disc relative to the stone (ie, increasing V1) is accelerated, thereby improving the grinding efficiency; In fine grinding and fine grinding, in order to improve the grinding quality, the grinding disc pressure should be reduced, the grinding disc speed should be increased and the moving speed of the grinding disc relative to the slate should be reduced.

In fact, in the continuous mill, whether it is rough grinding or fine grinding, the speed of the grinding disc relative to the slate is the same. Therefore, the selection of grinding process parameters mainly consider the following points:

1 The magnitude of the grinding pressure is proportional to the wear of the grindstone and also proportional to the grinding efficiency. The grinding head pressure in the rough grinding process is about 5-8 bar, and the grinding head pressure in the fine grinding and fine grinding is about 3-6 bar.

2 The forward speed of the conveyor belt is related to the quality of the grinding and polishing. It should be selected according to the roughness of the wool board and the type of the stone. Generally, the feeding speed of the conveyor belt is 0.2-0.6 m/min when grinding granite sheets. When the gabbro and basalt type plates are used, the feed rate of the conveyor belt is 0.5 to 0.8 m/min.

3 The reciprocating swing speed of the mill beam is about 4~10m/min. When the slate is wide, take a high value. When the slate is narrow, take a low value.
