A kind of cone crusher making method

Cone crusher is widely used in mining, smelting, building materials, highway, railroad, water conservancy, chemical industry, etc. The cone crusher is suitable for crushing raw materials in metallurgy, construction, road construction, chemical and silicate industries. With large crushing rate, high efficiency, low energy consumption and uniform product size, cone crushers are suitable for medium and fine crushing of various ores. The cone crusher of the prior art is generally equipped with only one body bushing, the stability of the body is poor, and the cone crusher is limited to withstand the crushing force and cannot use higher rotation operation, which reduces the crushing efficiency and crushing effect. At the same time, in the prior art, the adjusting sleeve is generally fixedly connected to the crushing mortar wall, and in the actual working process, the impact extrusion of the ore and the friction between the material and the liner will lead to the abrasion of the crushing mortar wall and the crushing wall, gradually increasing the width of the crusher discharge opening and affecting the crushing effect.  

Technical point: The cone crusher provided by the technician aims to solve the problems existing in the above-mentioned background technology. In order to achieve the above technical purpose, the cone crusher adopts the following technical solution: a cone crusher, including a frame, a spindle is vertically fixedly installed in the frame, an eccentric sleeve is rotatably installed outside the spindle through the eccentric sleeve, a cone is fixedly installed outside the eccentric sleeve, a crushing wall is fixedly installed outside the cone, a crushing mortar wall is provided on both sides of the outer wall of the crushing wall, and a dense edge discharge opening is provided between the crushing mortar wall and the crushing wall on one side. The other side has a loose edge outlet between the crushing mortar wall and the crushing wall, and the upper side wall of the crushing mortar wall on both sides has an adjusting sleeve removably installed through the connecting member; the lower side wall of the rolling mortar wall is matingly connected to the adjusting sleeve; the cone has a first projection toward the inner side on the central axis and a second projection toward the inner side under the central axis; the connecting member includes a wedge, and a clamp plate is fixedly installed above the top of the wedge, and the clamp plate The ring plate is fixed along the circumference of the ball nut, and the ball nut is threaded to the square head bolt, and the square head bolt is connected to the adjustment sleeve. The inner wall of the adjusting sleeve is fixed with a stopper, which can limit the rotation of the square head bolt; the square head bolt is covered with a sponge; the sponge is located between the end gap of the spherical nut and the square head bolt; the periphery of the wedge is covered with a cushion; the side of the cushion is fixed with an adaptor ring. The upper part of the conical body also has a body spherical bearing fixed by bolts; the body spherical bearing is rotatably mounted on the bowl tile, which is fixedly mounted on the bowl bearing seat, which is fixedly mounted on the top of the main shaft; the bolt is also threaded to the nut; the top of the nut also has a distribution plate fixed by screws; the upper part of the crushing wall also has a feed hopper communicating with the crushing chamber. The main shaft passes through the lower main bracket and is fixedly connected to the lower main bracket; there is a large bevel gear fixed on both sides of the lower main bracket, which engages with a small bevel gear fixedly pressed on the drive shaft, and the small bevel gear is fixedly connected by a pulley, which is driven by a drive motor; the drive shaft is rotatably mounted on the frame by a drive shaft bushing.

Compared with the existing technology, the above cone crusher has the following beneficial effects: the cone crusher is provided with two bushings, including the upper bushing and lower bushing of the body, which have good stability to the eccentric bushing and can withstand larger squeezing pressure and higher rotational speed; meanwhile the adjusting bushing is removably mounted on the crushing mortar wall through the connection, which is easy to replace the crushing mortar wall after it wears out and is conducive to ensuring the crushing effect.
