Box feeder with crushing roller

Through the successful development and use of box feeders according to DBGM G 9317208 with hydraulic ratchet feed that is effective over the entire length, larger feeder lances can be manufactured without placing greater strain on the floor chain.

Crushers or pan mills are often connected as downstream machines to carry out the material crushing in the first stage. Such crushers as single or double shaft machines are complex, but necessary. A well-known single shaft crusher requires a hydraulic press shield to periodically press the material against the crushing roller. After the roller is retracted and the filling chamber is refilled, this periodic crushing process takes place again.

The aim of the invention is to make the crushing process continuous in order to achieve higher performance so that the subsequent machines can be fed continuously. Furthermore, the construction effort and space requirements should be reduced.

According to the invention, it is proposed (according to Fig. 1) to arrange at least one crushing roller (10) in front of the box feeder (la). By developing the box feeder according to DBGM G 9317208, considerably longer feeders with correspondingly greater thrust forces at the material discharge end of the same can be designed. This makes it possible to achieve the required pressure of the bulk material (7) at the discharge end of the feeder (la) in order to continuously convey and press it against the crushing roller. Long feeders are made possible by the hydraulic feed (5) with cam rods and thrust cams (4) arranged on them. The unloaded floor chain (1) with its rigid deflections (2) also permits high bulk boxes (3), the exit height of which can be regulated by front adjustable slides (6). According to the invention, a rapidly rotating crushing roller (10) is arranged at the outlet of the box feeder, which can be operated with known crushing tools depending on the Bulk material hardness is fitted. A feed section (14) is arranged after the adjustable slide (6) and the crushing roller (10). It is based on the weight and friction conditions of the bulk material and also the length of the floor chain (1). A counter belt (11) that can be adjusted from above and driven if necessary also ensures a continuous feed of the bulk material to the crushing roller (10). The counter belt can also be designed as an adjustable pressure plate and spring- or pressure-loaded (e.g. hydraulically). As is known, a scraper (8) is connected to the front of the floor chain (1), followed by a crushing edge in front of the crushing roller (10). The crushed material (13) is taken up by a conveyor (12) underneath as usual.

The box feeder according to the invention combines two machines into one, which results in considerable savings in terms of construction, costs and space. The elimination of a conventional discharge reel and a hydraulic press shield also results in lower energy consumption.

The box feeder according to the invention may at most be made longer by the inlet section (14). However, this is only possible in cases where the box feeder is not already long and high enough to produce the necessary thrust of the material flow to be discharged.
