て作業環境を汚染するという問題がある。2. Description of the Related Art Waste fiber reinforced resin articles are conventionally used only for landfills because of their difficulty in recycling and reuse. However, they are crushed to an appropriate particle size and used for cement firing. Attempts have been made to use it as a solid fuel.
(JP-A-6-8247). However, the crushed granules of the waste fiber reinforced resin article have a problem that the reinforcing fibers protrude from the crushed cross section and are easily broken, and the broken fine fibers are scattered to contaminate the working environment.

運転費などにおいて、技術的、経済的困難がある。[0003] Generally, in a cement sintering facility, a crushing or crushing facility for waste fiber reinforced resin articles is not installed. Therefore, when a crushing or crushing apparatus for this waste fiber reinforced resin article is newly installed, this apparatus is required. However, there is a practical problem that it is difficult to obtain an installation space even if it is installed near a cement firing facility. For this reason, the device for crushing waste fiber reinforced resin articles is installed at a location remote from the cement firing device. In order to transport the crushed granules in this case through a pneumatic transport pipe or the like to the cement sintering apparatus in a closed state, the transport distance is long, so there are technical and economic difficulties in installation of transport facilities and transport operating costs. .

題がある。[0004] For this reason, crushed waste fiber reinforced resin articles are transported from the crushing device to a fuel hopper of a cement burning device using a dump truck or the like. In this case, in the handling of loading and unloading of the crushed material of the waste fiber reinforced resin article in the dump truck, loading and unloading work into the fuel hopper of the cement firing device, the resin reinforcing fiber projecting from the crushed section is broken,
There is a problem that the fine fibers are scattered in the air to deteriorate the working environment.

であった。[0005] In order to solve or alleviate this problem, attempts have been made to spray water on the crushed waste fiber reinforced resin to prevent the broken fiber from scattering, but as a result, the crushed material contains water and, therefore, its fuel efficiency. Practical use of this approach is problematic because the effect is significantly reduced. To further solve the above problem,
Attempts have been made to install a local dust collector at the work site, but there has been little improvement in the work environment and its practical use has been difficult.
