This equipment has many advantages such as large crushing ratio, strong crushing capacity, low noise, simple structure, and easy maintenance. It can crush ores of various hardness and is particularly suitable for medium and fine crushing operations.

[0003] The existing device has some disadvantages during use. For example, it is found that the raw material humidity is too high, which will affect the crushing effect of the roller crusher. The raw material with too high humidity is easy to adhere to the roller of the crusher, increasing the resistance of the roller and reducing the crushing efficiency. In addition, the raw material with high humidity is also easy to cause blockage and accumulation. Utility Model Content

The raw material with too high humidity is easy to adhere to the roller of the crusher, which increases the resistance of the roller and reduces the crushing efficiency. In addition, the raw material with high humidity is also easy to cause blockage and accumulation.

[0005] The utility model provides the following technical solution: a double-roll crusher, comprising a processing frame, a feed pipe is embedded in the top of the processing frame, the feed pipe is connected to the inner side of the processing frame, the inner side of the processing frame is provided with an auxiliary material guiding mechanism, a crushing mechanism and a collecting frame in sequence from top to bottom, the collecting frame is placed on the inner bottom wall of the processing frame, a rectangular opening for pulling the collecting frame is provided on the side wall at the bottom of the processing frame, a hot air blower is fixedly connected to the two opposite side walls at the top of the processing frame, and the air outlet of the hot air blower extends to the inner side of the processing frame.

[0006] In the above scheme, the feed pipe is connected to the external raw material source and guides it into the processing frame. The feeding of the device is intermittent feeding to prevent blockage or overload. The auxiliary material guiding mechanism is used to guide the raw materials into the crushing mechanism to ensure the uniform flow of the raw materials. The raw materials are crushed by the set crushing mechanism. The hot air blower is used to provide hot air to dry the material, which is helpful for further processing or improving the separation effect of the material.

[0008] In the above scheme, the driving mechanism is set to drive the rotating rod to rotate intermittently, so that the rotation time of the material guide frame is extended, thereby providing drying time for the raw materials, which is used to improve the separation effect of the materials and prevent the wet raw materials from sticking to the crushing mechanism.

[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0020] In the utility model, hot air is blown out by a hot air blower, and the hot air is used to dry the material, because the reduction of water molecules reduces the internal binding force of the material. When the material is relatively dry, its hardness is higher and it is easier to be crushed, which is helpful for further processing or improving the separation effect of the material, and avoiding the sticking of the crushing roller by the material with too high humidity, while improving the crushing effect and avoiding sticking and blocking of the material. The auxiliary material guiding mechanism and the driving mechanism are coordinated to rotate intermittently, so that the rotation time of the material guiding frame is prolonged, thereby prolonging the contact time between the raw material and the hot air, thereby providing a certain drying time for the raw material. The device dries the raw material during the feeding process, and improves the crushing efficiency of the crusher to a certain extent. BRIEF DESCRIPTION OF THE DRAWINGS
