Description

Cone crusher with aggregate supply distributor and aggregate production method using the same

The present invention relates to a cone crusher having an aggregate supply distributor and an aggregate production method using the same, and more particularly, to a cone crusher having an aggregate supply distributor capable of controlling the production amount of aggregate for each particle by controlling the aggregate supply amount and aggregate production using the same it's about how

In general, in the case of a cone crusher, when the main shaft rotates while the cone cave is at the fixed end and the mantle is at the movable end, an eccentric rocking motion occurs between the mantle and the cone cave and crushing of aggregate occurs.

That is, when the main shaft moves to one side, the distance between the mantle and the cone cave is narrowed on the other side with respect to the central axis, and crush crushing of the aggregate occurs. .

Here, the side where the distance between the mantle and the cone cave is narrowed is called the closed side, and the side where the distance between the mantle and the cone cave is narrowed is called the open side. Main crushing occurs on the closed side, so that when a large amount of aggregate enters the closed side, the production of fine-grained aggregate increases, and when a large amount of aggregate enters the open side, the production of coarse-grained aggregate increases.

The conventional conventional cone crusher does not consider the crushing characteristics of the cone crusher as described above, and the aggregate is supplied equally to the closed side and the open side to be crushed to produce aggregate.

Therefore, in the conventional aggregate production method using a conventional cone crusher, equal aggregate is supplied to the closed side and the open side, and the clearance on the open side becomes a factor determining the maximum particle size of the aggregate to be produced, and the particle size with a small clearance on the closed side Aggregate is produced by adjusting the particle size of

Hereinafter, a relationship between the rotation of the mantle and the clearance between the cone crusher will be described with reference to FIG. 1 .

FIG. 1 is a view for explaining a change in clearance according to the behavior of the mantle, and FIG. 2 is a graph showing the gap between the gaps according to the rotation angle of the mantle.

1 and 2, the mantle and cone cave form a crushing mechanism by rotational motion of a structure having a three-dimensional conical shape, but when depicting the relative motion in two dimensions based on one cross section of the z-axis, as shown in FIG. can be displayed

Here, if the radius of the cone cave is r ₂ , the radius of the mantle is r ₁ , and the center of the mantle is x=h,

In this case, the minimum value of the gap between the mantle and the cone cave is r ₂ - r ₁ - h (when θ = 0), and the maximum value of the gap between the mantle and the cone cave is r ₂ - r ₁ + h (when θ = 180) )to be.

On the other hand, in order to obtain the gap of play for an arbitrary angle θ, it can be obtained by solving the following two nonlinear equations using geometric conditions.

) [수학식 1]xsin(θ) = r ₁ sin(

) [Equation 1]

) [수학식 2]xcos(θ) = h + r ₁ cos(

) [Equation 2]

From Equations 1 and 2, x can be obtained as a function of θ, and g(θ), which is an interval between gaps for an arbitrary angle, can be obtained by Equation 3 below.

g(θ) = r2 - x(θ) [Equation 3]

When the gap between the gaps according to the rotation angle of the mantle is obtained by analytically solving using Equations 1 to 3, the minimum gap 0.5 at 0 degrees and the maximum gap 1.5 at 180 degrees change in sin form as shown in FIG. In the case of cone cave radius: r ₂ = 10, mantle radius: r ₁ = 9, mantle center: h = 0.5) From this, an open area and a closed area are divided in consideration of the rotational direction.

In addition, the conventional conventional cone crusher supplies the aggregate to be crushed into the hopper using equipment such as a conveyor, and it collides with the distributor at the top of the main shaft and is evenly distributed in the 360-degree direction through this, so that the closed side and the open side are equally distributed. is put in

In the conventional conventional cone crusher and aggregate production method using the same, when aggregate with small quality fluctuations is input, the particle size can be adjusted, but the production of fine and coarse particles cannot be controlled. There is a problem in that the particle size fluctuation occurs, resulting in the production of unacceptable aggregates.

Therefore, it is an object of the present invention to control the aggregate supply amount to the closed side and the open side formed between the mantle and the cone cave according to the target fine aggregate production rate and the target aggregate grain size, so that the production rate of fine aggregate and coarse aggregate can be freely adjusted.

It may include a driving motor whose rotational speed is controlled by the

For another example, the hopper rotation unit includes a first power transmitting means receiving a rotational force from a cone crusher driving motor for rotating the mantle, a decelerating means receiving the rotational force from the first power transmitting means and decelerating at a predetermined ratio; , may include a second power transmission means for receiving the rotational force outputted by being decelerated at a predetermined rate from the reduction means to rotate the rotary hopper at the same rotational speed as the mantle.

A pair of aggregate guide plates may be included to guide and supply aggregate passing through the variable gate in a lateral direction in which the variable gate is opened.

In addition, in the initial setting stage of the mantle and cone cave, the open state of the variable gate in the closed or open direction is adjusted in advance and fixed, and then a predetermined amount of aggregate is supplied to the aggregate supply distributor to produce aggregate. Calculating the production rate of fine aggregate according to the open position of the variable gate of the supply distributor; examining the crushing particle size of the aggregate according to the opening position of the variable gate of the aggregate supply distributor; Fine aggregate according to the opening position of the variable gate of the aggregate supply distributor Comparing the production rate and the target fine aggregate production rate, determining the open position of the variable gate so that the fine aggregate production rate can match the target fine aggregate production rate, and targeting the aggregate crushing particle size according to the variable gate opening position of the aggregate supply distributor Determining an open position of the variable gate so that the crushed aggregate grain size can match the target produced aggregate grain size compared with the produced aggregate grain size, and variable depending on the opening position of the variable gate according to the target fine aggregate production rate and the target produced aggregate grain size The steps of fixing and setting the open state of the variable gate by rotating the gate around the gate shaft and fixing it; measuring the fine aggregate production rate and the aggregate grain size of the produced aggregate after reproducing If not, we propose an aggregate production method using a cone crusher with an aggregate supply distributor comprising the step of re-adjusting the open state of a variable gate so that the fine aggregate production rate and the aggregate grain size of the produced aggregate coincide with the target fine aggregate production rate and the target produced aggregate grain size do.

As described above, the cone crusher having an aggregate supply distributor and the aggregate production method using the same according to an embodiment of the present invention are the variable gates so that aggregate is supplied to the closed side or the open side according to the target fine aggregate production ratio and the target aggregate grain size. Because the opening state is controlled, the fine aggregate production rate and aggregate grain size can be easily adjusted.

Therefore, the cone crusher having an aggregate supply distributor according to an embodiment of the present invention and an aggregate production method using the same can produce aggregate by very easily controlling the production ratio of fine and coarse aggregates and the aggregate particle size.

In the initial setting stage of the mantle and cone cave, the open state of the variable gate in the closed or open direction is adjusted in advance and fixed, and a predetermined amount of aggregate is supplied to the aggregate supply distributor to produce aggregate, Calculating a fine aggregate production rate according to the open position;
examining the aggregate crushing particle size according to the variable gate opening position of the aggregate supply distributor;
determining the opening position of the variable gate so that the fine aggregate production rate according to the variable gate opening position of the aggregate supply distributor and the target fine aggregate production rate are compared so that the fine aggregate production rate coincides with the target fine aggregate production rate;
comparing the aggregate crushing particle size according to the variable gate opening position of the aggregate supply distributor with the target produced aggregate particle size to determine the open position of the variable gate so that the aggregate crushing particle size coincides with the target produced aggregate particle size;
setting the variable gate by fixing the open state of the variable gate by rotating the variable gate around the gate shaft according to the target fine aggregate production rate and the opening position of the variable gate according to the target aggregate grain size;
measuring the fine aggregate production rate and the aggregate particle size of the produced aggregate after regenerating the aggregate by injecting a predetermined amount of aggregate into the aggregate supply distributor in a state in which the variable gate is set in a fixed open state; and
If the fine aggregate production rate and the aggregate grain size of the produced aggregate are re-compareed with the target fine aggregate production rate and the target produced aggregate grain size, aggregate is produced. A method for producing aggregate using a cone crusher having an aggregate supply distributor, comprising the step of readjusting the open state of the variable gate to match the production aggregate grain size.
