Tooth knife type coal product breaker and mixer and method for crushing and mixing clean coal and slime cake

Abstract

The invention relates to a coal product breaking and mixing machine and is suitable for the breaking and mixing process of clean coal and filter-pressed coal slime cake in a coal preparation system. The toothed cutter type coal product breaking and mixing machine comprises a motor, a belt driving mechanism, a fixed foundation bed and a crushing box body of which two ends are communicated; the toothed cutter type coal product breaking and mixing machine is characterized in that a toothed cutter is arranged in the crushing box body, a wear-resisting plate is inlaid in the inner wall of the crushing box body, the communicating surface of the fixed foundation bed and the crushing box body is provided with discharging through holes with consistent size, and the lower through hole surface of the crushing box body is fixed on the fixed foundation bed and corresponds to the position of the discharging through hole; the toothed cutter type coal product breaking and mixing machine adopts the main principle as follows: an electric motor is utilized for driving a rotor to rotate at high speed, a blade designed to have special shape and mounting position is arranged on the rotor, coal and coal slime cake mixture charged above the blade is broken by the blade in a blade rotating process, and impart force during breaking can vibrate and mix the coal and the broken coal slime cake, and therefore, the purpose of breaking and mixing the coal and the coal slime cake can be achieved.

Description

technical field [0001] The invention relates to a set of coal product breaker and mixer, which is suitable for the crushing and mixing process of clean coal and coal slime cake after pressure filtration in a coal preparation system. Background technique [0002] The calorific value of press filter slime cake produced in the process of some coal preparation plants in China is 5000-7000 kcal, and its quality index is equivalent to that of clean coal. If it is crushed and mixed with clean coal for sale, it can increase the economic benefits of the enterprise. benefit. Common crushers in China mainly include hammer crusher, jaw crusher, roll crusher, cone crusher, impact crusher, impact crusher and so on. Most of them can realize the crushing of coal slime cake, but cannot realize the purpose of mixing clean coal more uniformly. [0003] Common coal mixers in China mainly include twin-shaft screw mixers, twin-shaft blade mixers, etc. Such equipment can realize coal mixing, bu...
