The discharging granularity of sand and gravel is small, the particle shape is uniform, the production capacity is large, the hammer has long service life, the supporting power is low, the three-stage crushing is changed into two-stage crushing, the process is simplified, the structure is simple, the maintenance is convenient and the operation is stable. The equipment investment is 35%-50% lower than the traditional process equipment of the same scale, and the output efficiency is 35%-50% higher than the traditional process equipment of the same scale. Take limestone as an example: the particle size of a finished product ≤5mm accounts for more than 85%. The operation and maintenance cost is 35%-50% lower than that of traditional process equipment of the same scale. River pebble sand making machine is suitable for crushing and forming soft or medium hard and extremely hard materials.

Workflow of river pebble sand making machine

The river pebble sand maker firstly sends river pebbles into a vibrating feeder through a silo, a part of slightly smaller river pebbles screened by the feeder is sent into a transition silo through a cleaning belt, the larger river pebbles are sent into a jaw crusher for coarse crushing, and then the materials in the transition silo are relatively uniform, and then are sent into an impact crusher for fine crushing, and then screened by a vibrating screen, and the larger materials are returned to the impact crusher for crushing. The fine materials screened by the vibrating screen are sent to the third generation sand making machine for sand making, and the slightly larger materials after sand making are returned to the sand making machine for sand making, and the fine materials are screened out of the finished sand by the vibrating screen.

Installation of river pebble sand making machine

1. River pebble sand making machine is installed on concrete foundation or steel structure foundation, and the foundation should be able to bear 4 times the weight of the whole machine.

2. According to the site of the crusher, it is installed in the workshop or in the open air. During installation, the crusher should be kept horizontal so that its main shaft is perpendicular to the horizontal plane.

[13] The lifting equipment should be set above the river pebble sand machine, and the capacity of the lifting equipment should be considered according to the maximum weight of the crusher. There should be lifting space above the river pebble sand machine, and there should be appropriate space on one side of the river pebble sand machine for maintenance. Pebble sand making machine is a special equipment for producing sand and stone for building. Connect into a line with a belt conveyor. On this production line, the high-speed rotating wheel is used to throw stones out at a linear speed of 76m/s and collide with the wear-resistant liner, forming the principle of stone-to-stone and stone-to-iron crushing. It ensures the smooth discharge of the whole process, reliable operation, high efficiency and energy saving, and saves energy by 50% compared with traditional equipment.

It is one of the sand-making equipment widely used in sand and gravel industry. It is mainly used for processing raw materials such as crushed feldspar, timely, ore, etc. It is also suitable for manufacturing abrasives, refractories, cement, steel sand, slag powder, copper mine, iron mine, gold mine, concrete aggregate, asphalt aggregate, etc.

Working principle of sand making machine with rod mill

Working principle of the rod mill sand making machine: the cylinder of the rod mill sand making machine rotates at a certain speed, and the grinding body rises to a certain height and is thrown down under the action of friction and centrifugal force, so that the material is impacted and ground to achieve the purpose of sand making.

Structure of sand making machine of rod mill

The sand making machine of rod mill consists of main parts such as feeding part, discharging part, rotating part and transmission part (reducer, pinion, motor and electric control).

3. Advantages of rod mill sand making machine.

(1), power saving-saving more than 40% compared with the old equipment.

⑵ The advanced controllable feeding and discharging rod mill technology is adopted to match the grinding materials of actual users with suitable grinding bodies, so that the surface contact of the traditional ball mill is changed into line contact, and the discharging granularity of the sand mill is more uniform and the output is higher, which is suitable for ores with different hardness (Mohs hardness 5.5 ~ 12).

(3) The fineness of discharging can be adjusted-the granularity of discharging can be changed by simple adjustment. Built-in fineness control device, and screening device can be added to ensure that it will not be over-ground and unqualified products will not be mixed into finished products.

(4) There are two kinds of rod mills to choose from: dry and wet. Users can choose according to their actual situation. For processed quartz sand, dolomite, monazite and other products, iron can be removed by magnetic separator after grinding.

In addition to these equipments, the machine-made sand production line also includes VSI new sand making machine, PCL sand making machine, impact sand making machine, composite sand making machine, high-efficiency fine crusher and other equipments.
