Clay Sand Raymond Mill
Clay sand Raymond mill is my company production of a the closed cycle, high fine milling equipment, through years of practice and continuous improvement, its structure has been perfected. In a certain extent can instead of ball mill.
Clay sand Raymond mill is suitable for processing Mohs hardness of 7 below, the humidity below 6% of all non flammable and explosive ore, is widely used in small and medium-sized mines, chemical industry, building materials, metallurgy, refractory material, pharmaceutical, cement and other industries.
Clay sand Raymond mill Structure
Clay sand Raymond mill is a kind of mechanical grinding, fineness of 0.044mm of dry powder, and with air grading device, which can be adjusted continuously and automatically work. The Clay sand Raymond mill structure mainly includes host, analyzer, fan, finished cyclone separator, powder cyclone separator and wind pipe mill. Among them, the host is composed of a machine frame, inlet volute, blade, grinding roller, grinding ring, shell etc.
Clay sand Raymond mill working principle
Clay sand Raymond mill grinding ring, a chassis, the chassis is arranged in the middle of the hollow column, as the spindle bearing. The main shaft is arranged in the middle of the hollow column, driven by the motor 1 through the reduction device. The main shaft is provided with a plum frame, and a short shaft is used to hang the roller 5, so that the roller can rotate around the shaft. The middle roller grinding roller shaft rotates freely, the lower end of a roller shaft.
The number of each mill roll is 3-6, evenly arranged along the Mei flower for four weeks. Under the plum frame, equipped with scraper. When the spindle rotates, grinding and due to the action of centrifugal force pressed on the grinding ring and thus the wear and in addition by the spindle drive around the center line of the mill rotation of the orbital motion of outside, and because of the friction between the ring and the roller mill and the rotation movement. From the feeder with falling materials on the chassis scraper to scrape, spilled to the ground in front of the roller grinding ring on, when the material is not falling, grinding and pulverizing. In the vicinity of the lower edge of the chassis, which is provided with an air inlet and an air duct. Qualified products under the action of the wind through the top of the classifier discharged by the classifier separated unqualified part and return to the mill to grind, Raymond mill is carbon, electrical carbon industry choose a kind of more.
Clay sand Raymond mill grinding materials, the fan will wind blowing in the machine shell, blowing powder, milling machine is arranged in the grinding chamber at the top of the parser, sorting, fine through thick materials and fall into the grinding chamber heavy grinding, the fineness conforms to the specifications of the wind flow into the cyclone collector, collected by the powder outlet discharge, is finished.
Raymond Mill airflow by the large cyclone collector is arranged at the upper end of the return pipe back into the fan, wind road is cyclic, and in the state of negative pressure flow and mill circulating wind path of air volume increased part discharged by the air blower and the host in the middle of the exhaust pipe and into the small whirlwind collector, purification treatment.
When Clay sand Raymond mill work will need to be crushed material from the side of the hood shell into the hopper joining machine, hanging in the mill host frame mill roller device from around the axis perpendicular to the revolution, and rotation, due to the action of rotating centrifugal force, milling machine grinder roll outward swinging, tightly pressed on the grinding ring, shovel knife to scrape materials sent to the grinding roller and grinding ring, grinding machine for grinding roller rolling to the comminuted material.
Clay sand Raymond mill operation
- when working, the operator must have a certain technical knowledge and level, to carry out the operation.
- the machine must be in good lubrication condition, otherwise it will damage the bearing, shorten the service life. See the specific filling time and filling oil variety see lubrication system.
- no metal block into the machine, found that immediately stop out, otherwise it will damage the grinding roller and grinding ring.
- feeding should be uniform, too much will reduce the yield, duct blockage, easy to burn out the motor; too little will lower the yield.
- air conditioning: located in the wind turbine inlet pipe on the air flow control valve, generally open to the maximum position, according to the fineness, production requirements of appropriate adjustments.
- fineness adjustment: according to the size of the material, soft and hard, water content, specific gravity, processing of the thickness is also different, can adjust the top of the analyzer, high speed, high fineness, low speed, fineness is low. Improve the fineness, the output will be reduced, if not up to the requirements of the wind turbine should be debug and speed, the user can be flexible to master.
- grinding roller grinding ring scrap limit, the remaining minimum wall thickness shall not be less than 10mmm.
- Stop, stop feeding, the host is still running, the residual material to grinding, about a minute later, off the host motor and analyzer motor, stop the grinding work afterwards, stop motor of fan to blow the net residual powder.
