Product Introduction
The rod mill type sand making machine adopts advanced controllable feeding and discharging rod mill type sand
making machine technology, and the hollow shaft also uses cast steel parts, and the lining can be replaced. The
rotary gear is processed by casting hobbing, and the cylinder body is embedded with The grinding lining board has
good abrasion resistance. In addition, the equipment is also combined with the actual user's grinding material and
equipped with a suitable grinding body. Once the surface contact of the traditional ball mill is changed to line
contact, the particle size of the sand machine is more For uniformity and higher output, it is suitable for ore of
different hardness.
In terms of production, the rod mill type sand making machine is 10-20% higher and saves power by more than 40%
compared with traditional equipment. It is currently a relatively effective and practical and reliable crushing
stone sand making machine. It is used in the processing and crushing of quartz, ore and other raw materials. It is
also suitable for the production of abrasives, refractory materials, iron ore, gold ore, cement, slag powder, copper
ore, concrete aggregate, etc.
Working principle of rod mill sand making machine
The rod mill type sand making machine is driven by a motor through a reducer and a surrounding large gear to
reduce the speed, or a low-speed synchronous motor directly through the surrounding large gear to reduce the speed,
and drives the cylinder to rotate. A suitable grinding medium-steel rod is installed in the cylinder. The grinding
medium is lifted to a certain height under the action of centrifugal force and friction force, and falls in a state
of being dropped or leaked. The milled material enters the cylinder continuously from the ore feeding port, and is
crushed by the moving grinding medium, and the product is discharged out of the machine through the power of
overflow and continuous ore feeding for the next stage of operation. The particle size characteristics of the rod
mill products are related to the condition of the rod mill. When the rod hits the ore, it first hits the coarse
grains, and then grinds the smaller grains, thereby reducing the risk of over crushing. When the rod rotates along
the lining, the coarse particles are sandwiched between them, like a rod sieve, allowing the fine particles to pass
through the gap between the rods. This is also conducive to crushing the coarse particles and concentrate the coarse
particles in the grinding medium. The place to hit. Therefore, the product of the rod mill is more uniform, and the
over-pulverization is lighter.

Performance advantages of rod mills
1. Save 40% more power than older equipment.
2. Adopting advanced controllable in and out rod mill type sand making technology, combined with the actual
user's grinding material and using appropriate grinding bodies, changed the surface contact of the traditional ball
mill to line contact, making the particle size of the sand making machine more For uniformity, less over-pulverized
ore particles, higher output, suitable for ore with different hardness (Mohs hardness 5.5-12).
3. Adjustable discharge fineness. The grain size of the discharge can be changed through simple adjustment. The
built-in fineness control device can be added to the screening device. Two checks are performed to ensure that
neither over-grinding nor use Substandard products are mixed into the finished product.
4. Henan Machine, as a professional rod mill manufacturer, can meet the production needs of different
users, and can be equipped with fineness control devices and discharge screening devices to ensure the quality of
finished products.
6. The steel rod structure used for striking materials inside the machine is designed and manufactured with
high-quality manganese steel, which is durable and durable.
