Rod mill sand making machine

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.
