In a method for producing powder or granular asphalt, which involves crushing and granulating a lumpy asphalt raw material with a size of 20 or less using a crusher, the asphalt raw material is crushed by high-speed rotation of a rotary blade attached to a vertical rotating shaft, and then 360 degrees A method for producing powdered or granular asphalt is disclosed, which is characterized in that it is discharged through a screen with intermittent discharge over the entire surface.
しかし、粉砕による造粒では所望の粒度の粒状アスファ
ルトを高収率で得ることはできず、また、形状が不均一
になるという欠点がある。However, granulation by pulverization does not allow granular asphalt having a desired particle size to be obtained at a high yield, and has the disadvantage that the shape becomes non-uniform.
従って、本発明の目的は高収率で所望の粒度の粒状アス
ファルトを得ることができる粒状アスファルトの製造方
法を提供することにある。Therefore, an object of the present invention is to provide a method for producing granular asphalt that can obtain granular asphalt with a desired particle size in high yield.

粒状アスファルトの製造方法に係る。[Means for Solving the Problems] That is, the present invention uses a briquetting machine or a compacting machine to select a powder raw material whose main component is an asphalt raw material having a penetration degree in the range of 0 to 20 at a molding temperature. The present invention relates to a method for producing granular asphalt, which is characterized in that it is granulated using a granulator.

The process is to granulate it.
本発明に使用できるアスファルト原料は特に制限される

マシンやコンパクテイングマシンでの造粒に適さない。The asphalt raw material that can be used in the present invention is not particularly limited, as long as it has a penetration degree at the molding temperature of 0 to 20. That is, when the powder raw material consists only of asphalt raw material, the penetration degree at the molding temperature is preferably within the range of 0 to 20. Asphalt raw materials with a penetration of more than 20 at the forming temperature become soft and are not suitable for granulation in briquetting machines or compacting machines.

用途等により適宜決定される。Moreover, an appropriate powder raw material can be added to the powder raw material whose main component is an asphalt raw material used during granulation in the method of the present invention. Examples of powder raw materials include inorganic powders such as talc, bentonite, diatomaceous earth, mica powder, stone powder, and glass powder, organic powders such as tire powder, resin powder, and book powder, glass fiber, rock wool fiber, pulp, aramid fiber, and cotton waste. Examples include finely ground fibrous powder. The amount of these powder raw materials added varies depending on the softness of the asphalt powder and the type of powder to be mixed, but asphalt powder 1
The amount is about 0 to 250 parts by weight per 00 parts by weight, and even if an asphalt raw material with an asphalt raw material penetration of more than 20 is used, the penetration of the powder raw material at the molding temperature is within the range of 0 to 20. It can be adjusted within. The type of powder raw materials to be mixed is appropriately determined depending on the use of the granular asphalt.
