Embodiment Construction

[0017] The reference signs in the description of the drawings are: frame 1, driving roller 2, driven roller 3, hydraulic cylinder 4, nitrogen bag 5, feeding device 6, spiral reamer 7, spiral channel 8, stopper 9.

[0018] like figure 1 As shown, this embodiment provides a rolling machine for calcium aluminate powder raw materials, including a frame 1, a driving roller 2, a driven roller 3, a driving motor, a hydraulic device 4 and a feeding device 6. The feeding device 6 is conical and fixed on the frame 1. The feeding device 6 is welded with a spiral passage 8, and a funnel-shaped feed opening is provided above the spiral passage 8. Raw materials enter the spiral channel 8 through the funnel-shaped feeding port, and enter the feeding device after preliminary mixing. like figure 2 As shown, the feeding device 6 is provided with a motor and a spiral reamer 7, and a plurality of stoppers 9 are welded on the spiral reamer 7. The feeding device 6 stirs the raw materials to mak...

Abstract

The invention belongs to the field of grinding products, and particularly discloses a roller press for calcium aluminate powder raw material. The roller press comprises a rack, a driving roller, a driven roller, a diving motor, a hydraulic device and a feeding device, wherein the driving roller, the driven roller, the diving motor, the hydraulic device and the feeding device are all mixed on the rack; the hydraulic device is connected with the driving roller; the driving roller and the driven roller are positioned in the same horizontal plane; the external diameters of the driving roller and the driven roller are the same; one end of the driving roller is connected with the output end of the diving motor; a driving gear is arranged at the other end of the driving roller; a driven gear meshed with the driving gear is arranged on the driven roller; the driving gear and the driven gear rotate in opposite directions; the feeding device is hollow and tapered; a stirring device is arranged in the feeding device. Harmful heat generated by the driving roller and the driven roller is absorbed through reaction, so that the wear rate of the roller surfaces is reduced, and the reaction product cannot react with calcium aluminate powder to generate impurities or hazardous substances.

Description

technical field [0001] The invention belongs to the field of grinding articles, and in particular relates to a rolling machine for calcium aluminate powder raw materials. Background technique [0002] The main component of calcium aluminate powder is calcium dialuminate (CaO 2A1 2 0 3 ) and calcium aluminate (CaO·A1 2 0 3 )mixture. The raw material of calcium aluminate powder is composed of limestone and bauxite. The bauxite and limestone are respectively crushed by a pulverizer and then calcined at a high temperature in a rotary kiln. into calcium aluminate powder. Calcium aluminate powder is mainly used as the raw material of polymeric water filter agent, high-efficiency concrete expansion agent and refractory castable, and has been widely used in chemical industry, environmental protection, sewage treatment and other fields. [0003] Roller press (high-pressure roller mill) is the latest generation of building materials, cement, metallurgy, mining, chemical industry...
