The difference between rod mill and impact sand making machine
Mainly, there are some differences in working methods, output, and grain size of the finished product. Which one to choose depends on the actual needs of various aspects.
1. Working method and structure
The rod mill is composed of a motor, a main reducer, a transmission part, a barrel part, a main bearing, a slow transmission part, a feeding part, a discharging part, an annular seal, a thin oil lubrication station, a large and small gear jet lubrication, a basic part, etc. .
Reduced transmission by the motor through the reducer and surrounding large gears or by the low-speed synchronous motor directly through the rod mill through the surrounding large gears to drive the cylinder to rotate. The cylinder is equipped with a suitable grinding medium-steel rod, and the grinding medium is in Under the action of centrifugal force and friction, it is lifted to a certain height and falls in a thrown or inclined state. The ground material enters the cylinder continuously from the feed port, is crushed by the moving grinding medium, and passes through The force of overflow and continuous feeding will discharge the product out of the machine for the next process operation.
The impact sand making machine is composed of seven parts: feeder, distributor, vortex crushing cavity, impeller experience, main shaft assembly, base transmission device and motor.
It adopts the working methods of “stone-on-rock” and “stone-on-iron”. Among them, stone-on-rock is suitable for materials with high corrosiveness above medium-hardness, such as basalt, which is mostly used for shaping and good grain; , Such as limestone, etc., with large output and high production efficiency.
2. Applicable materials
The rod mill is suitable for finely crushing various hard and brittle materials such as steel sand, slag powder, copper ore, iron ore, gold ore, concrete aggregate, asphalt aggregate, etc.
The impact sand making machine is suitable for all kinds of hard and brittle materials, such as river pebble, granite, limestone, quartz stone and so on.
The particle size of the rod mill is less than or equal to 25-50mm, and the controllable feeding and discharging technology is generally 0.833-0.147mm.
The feed size of the impact sand making machine is less than or equal to 30-55mm, and the hydraulic adjustment system discharges, usually 0.25-5mm.
4. Finished grain type
After rod milling machine-made sand, the particle size is relatively uniform, the over-crushed ore particles are few, and the edges and corners are basically flattened into an oval shape.
The impact sand making machine is more suitable for the production of fine sand, which has a shaping effect, and the sand has a good shape without cracks and fine lines.
The rod mill has an output of 0.62-180 tons per hour, small and medium-sized equipment.
|Model specification||Cylinder specification (mm)||Rotating speed of cylinder
The impact sand making machine has an output of 40-650 tons per hour. There are various models for your choice.
