Description

Technical Field

[0001] This utility model relates to an alternative fuel grinding machine for cement kilns. Background Technology

[0002] Single-shaft crushers operate at high speeds and use numerous small, square blades to cut materials, rapidly breaking down combustibles into smaller sizes. These smaller pieces are then filtered through a screen, ensuring the output size remains within a controllable range and meeting end-user requirements for alternative fuel sizes. However, single-shaft crushers also have disadvantages. These include lower efficiency when processing hard or large materials; wear and tear on blades and bearings after prolonged use, requiring regular replacement and maintenance, increasing operating costs; higher energy consumption when processing high-hardness materials, further increasing operating costs; limited capacity for handling complex materials due to their relatively simple structure, primarily applicable to soft and medium-hard materials, and potentially ineffective for highly fibrous or tough materials; and relatively low capacity, making them unsuitable for large-scale continuous production needs. Furthermore, screen clogging is common, requiring frequent cleaning and impacting overall efficiency. Summary of the Invention

[0003] This utility model provides a grinding mill for alternative fuels in cement kilns to solve the problems existing in the prior art.

[0004] The technical solutions adopted in this utility model are as follows:

[0005] A grinding mill for alternative fuels in cement kilns includes a grinding barrel, a mounting base, chains, a feeder, and a motor. The mounting base is rotatably connected inside the grinding barrel, and multiple chains are fixed to the outer circumferential wall of the mounting base. The motor drives the mounting base to rotate and causes the chains to move centrifugally.

[0006] Furthermore, the grinding machine also includes a frame and a feed hopper, the feed hopper being fixed on the frame, and the feed hopper and the grinding hopper being arranged coaxially and communicating with each other.

[0007] Furthermore, the discharge holes are distributed on the side and bottom surfaces of the grinding barrel cavity.

[0008] Furthermore, the grinding barrel is provided with a slag discharge port on the side of the cavity, and a gate is inserted into the slag discharge port.

[0014] Figure 1 This is a structural diagram of the present utility model.

[0015] Figure 2 This is a structural diagram of the present utility model. Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] like Figure 1 and Figure 2 This utility model discloses a grinding mill for alternative fuels in cement kilns, comprising a grinding barrel 1, a mounting base 2, a chain 3, a feeder 4, a motor 5, a feed barrel 6, and a frame 7. The grinding barrel 1 and the feed barrel 6 are both fixed on the frame 7. The grinding barrel 1 and the feed barrel 6 are coaxial and connected, and their inner diameters are the same.

[0018] Mounting base 2 is rotatably connected to the grinding barrel 1 via a shaft and bearing, and is arranged coaxially with the grinding barrel 1. Multiple chains 3 are evenly fixed to the outer circumferential wall of mounting base 2 by bolts. Motor 5 is linked to mounting base 2 via belt and pulley, and motor 5 drives mounting base 2 to rotate and causes the chains to move centrifugally.

[0019] Several discharge holes 11 are provided on the cavity wall of the grinding barrel 1. The discharge holes 11 are distributed on the side and bottom surfaces of the grinding barrel 1 cavity. The discharge holes 11 are connected to the feed inlet of the feeder 4. The feeder 4 is a screw feeder.

[0020] A slag discharge port 12 is also provided on the side of the grinding barrel 1, and a gate is inserted into the slag discharge port. A filter screen is provided on the side of the grinding barrel 1, located at the discharge port. Different pore sizes of filter screens can be replaced, which is suitable for filtering materials of different particle sizes.

[0021] The grinder uses a chain inside, which is wear-resistant and not easily damaged, offering advantages over single-shaft crushers for crushing medium to high hardness materials. For fabric strips, the chain drives them to rotate, causing friction against the inner wall of the grinder and producing fine fibers. Material is discharged through different sized discharge holes 11 to ensure optimal particle size. Adjusting the distance between the chain and the inner wall of the grinder during rotation ensures efficient discharge.

[0022] The material enters through the feed inlet of feed hopper 6. Depending on the properties of the material, the effect of the chain crusher will vary. Materials with a certain rigidity, such as biomass, plastics, and paper, will be crushed by the chain. When the material is crushed to the size of the screen, it will be squeezed by the chain and discharged through the slag outlet.

[0023] Flexible materials such as fabrics and fibers are driven by the chain, and the friction between the grinding mill's inner wall and the materials themselves creates a fine, fluffy material, which is then extruded through compression. Any impurities can be manually discharged from the slag outlet by opening the sliding gate after the machine is stopped. Furthermore, the turbulent flow and the movement of the bulk particles achieve additional crushing and grinding effects. The impact and friction between the particles cause a temperature increase, while also releasing a certain amount of moisture. The screw feeder serves to transport the materials and further refine the crushing process.

[0024] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of the present utility model, and these improvements should also be considered within the protection scope of the present utility model.
