Ball mill for crushing tungsten carbide blocks produced by recycling waste hard alloy

Abstract

The invention provides a ball mill for crushing tungsten carbide blocks produced by recycling waste hard alloy, and belongs to the technical field of mining equipment. The ball mill comprises a fixed support, wherein an outer wrapping barrel is rotatably connected to the upper portion of the fixed support, and an inner barrel is rotatably connected in the outer wrapping barrel; a speed reducer and a driving motor are sequentially and fixedly connected to the position, located on the right side of the outer wrapping barrel, above the fixed support from left to right, and the speed reducer and the driving motor are in transmission connection through a rotating shaft. The ball mill for crushing the tungsten carbide blocks produced by recycling the waste hard alloy is provided with crushing edge blocks, when the crushing edge blocks are acted by two strands of opposite centrifugal force, the two strands of centrifugal force separately act on two stress plates with different inclination angles to generate a pushing effect, so that the centrifugal force pushes side face unfolding blocks to be unfolded outwards, and when the side face unfolding blocks are unfolded, bottom unfolding blocks are extruded and pushed to be unfolded outwards, so that the crushing edge blocks conduct crushing operation of cutting and impacting on materials after being overall unfolded.

Description

technical field [0001] The invention relates to the technical field of mining equipment, more specifically, to a pulverizing ball mill. Background technique [0002] The ball mill is the key equipment for crushing the material after it is crushed. This type of grinding machine is filled with a certain number of steel balls in its cylinder as the grinding medium. It is widely used in cement, silicate products, new building materials , refractory materials, chemical fertilizers, black and non-ferrous metal beneficiation and glass ceramics and other production industries, dry or wet grinding of various ores and other grindable materials, ball mills are suitable for grinding various ores and other materials, and are widely used It is used in mineral processing, building materials and chemical industries, and can be divided into dry and wet grinding methods. [0003] Tungsten carbide is a compound composed of tungsten and carbon. Its molecular formula is WC and its molecular wei...

Problems solved by technology

[0004] Among them, the application number is CN201810557767.2, which is a safety ball mill for mineral crushing, including a frame, a fixed cylinder and a ball mill cylinder. It is fixedly connected with the frame through a number of support rods; through the setting of the emergency brake device, when the machine needs to be stopped in an emergency, the brake card will clamp the brake disc after pressing the pedal with the foot, resulting in The huge frictional resistance makes the brake disc stop running together with the drive shaft, thereby avoiding accidents. Through the setting of the blower, a strong downward wind is generated, which can blow off the materials blocked in the through hole of the ball mill cylinder, and avoid ball milling. The powdery material is agglomerated, thus ensuring the normal conveying of the raw material, and through the setting of the feeder, the material can be squeezed and crushed by the extrusion force between the conveying dragon and the inner wall of the cylinder during the conveying process, thereby speeding up the ball mill crushing In this technical solution, the material is squeezed and crushed by extrusion force. Although the purpose of gutter crushing efficiency can be achieved, it cannot further improve the effect of grinding precision, which leads to the crushing of the technical solution. The material specification can only reach the set specification
