The tens of years of customer service experiences make ZENITH learn better the customer's investment ideas and considerations so as to provide specific solutions.

Raymond Mill Features

1. Skills Features

Based on years of grasp of the ultra-fine powder equipment processing skills, we have all the above questions on the thorough technical innovation. In the use of traditional Raymond Mill found that Raymond Mill in the processing of calcite ore powder, 325 mesh slag contains a lot of 10um ultra-fine mineral powder, if you can separate and expand the output value, will greatly improve efficiency. To this end the Raymond mill structure carried out a lot of renovation:

The traditional approach to the host has been improved, the spindle and plum frame was conducive to a stable structural transformation, so that smooth operation.

Base no swing. Will be some of the traditional machine from the cavity drag, to the cavity outside the vertical drive within the drive two blocks of rotation, and then enhance the stability of its operations, durability. In the damaged area, so that the material to be ground has been assembled in the grinding area for useful processing, improve the Grinding Mill, we also updated the roller structure, so that grinding roller and roller shaft can be complementary operations. In the rotation together can also turn. Make it more effective and durable. And can work at greater grinding strength and higher operating speed. In the ventilation some, the bellows and duct are from the original flat to the base of the tilt to 30 degrees, constitute a bucket shape, to ensure that the bellows, duct has been dredging without blocking, and then keep the air volume required, the host grinding in high power. In the whole system planning, from the traditional secondary collection to four to collect. A two-level collection with a closed-loop negative pressure collection, no dust spill, three or four collection selection control spill dry and wet series to collect, root dust spill. All the system in the collection of ultra-fine powder together, eradicate or cut the pollution of the surrounding environment.

The above new Raymond Mill is capable of ultrafine grinding of non-metallic minerals such as calcite, dolomite, talc, tall earth, barite, rutile and fluorite. The output value can reach 450kg /h when the fineness is adjusted to 1250 mesh (10um), and the input power is only 23kw. It is more significant than the traditional Raymond mill. When the fineness is adjusted to 1250 mesh (10um) Higher cost.

2 Scope Modify

The construction of R-type Raymond Mill has been improved with years of practice and continuous improvement. It has the advantages of high utilization rate, low energy consumption, small footprint, little capital investment and no pollution to the environment. And thus widely used in metallurgy, building materials, chemicals, mining and other areas of mineral materials, grinding materials, suitable for processing Mohs hardness of seven below the humidity of 6% of the following non-flammable and explosive minerals, such as gypsum, talc Granite, kaolin, bentonite, medical stone, bauxite, iron oxide red, iron ore, etc., the fineness of products in the 613 microns to 440 microns (calcite, marble, potassium feldspar, barite, dolomite, 0.613 mm -0.44 mm), through the analysis machine and the role of the fan, can be satisfied with the user's needs.

3 Structural features modified

  • 1, Raymond Mill three-dimensional structure, covers an area of ​​small, complete sets of strong, from the block to the product powder into a separate production system.
  • 2, the product powder fineness uniformity, through the screen rate of 99%, which is difficult to have other milling equipment.
  • 3, milling machine mainframe transmission equipment used sealed gear box and pulley, smooth transmission, solid operation.
  • 4, Raymond Mill are the main components of the selection of excellent steel, wear parts are selected high-wear materials, machine wear high, reliable operation.
  • 5, the electrical system selection of centralized control, milling workshop can be completed almost no homework, and repair convenience.

4 operating principle changes

Raymond grinding operation principle is the roller under the action of centrifugal force tightly rolling on the grinding ring, shovel shovel material from the shovel and grinding ring base, the material under the action of rolling pressure broken into Powder, and then under the action of the fan into the powder material through the analysis machine, to achieve the fineness of the material through the analysis machine, can not meet the needs of the re-grinding chamber continued grinding, through the analysis of the material into the whirlwind separator Separate from the collection. Exhaust selection of industrial filter cloth barrier exhaust into a powder. Raymond Mill Scope This machine is mainly used for barite, calcite, potassium feldspar, limestone, talc, white stone, gypsum and so on. Mohs hardness of not more than 9.3, the humidity of 6% in the following non-flammable and explosive mineral products, chemicals, building materials, and other hundreds of high-fine powder processing materials, the size of the product in the 400- The The series of goods for different materials, not the same fineness, not the same output value and other needs, divided into high-pressure micro-grinding, forced hanging roller mill, usually Raymond three series of more than a dozen models.

Raymond Machine Accessories Raymond Machine Accessories

Raymond mill sets of construction is by the host, the analyzer (separator), pipeline equipment, blowers, products whirlwind separator, jaw crusher, bucket hoist, electromagnetic oscillation feeder, electric control motor constitute. In the meantime, Raymond Mill consists of a rack, a wind volute, a blade, a roller, a grinding ring, a casing and a motor.

Raymond mill the entire process (grinding material process): large pieces of material by the jaw crusher to the required particle size, the hoist will be sent to the storage hopper material, and then by the oscillation feeder evenly quantitative And then into the host grinding chamber for grinding, grinding powder after the fan airflow away. By the analysis machine for grading, fit the fineness of the powder with the air into the large whirlwind through the pipeline, the separation of the collection, and then discharged by the powder tube is the product powder. The airflow is then blown into the blower by the upper end of the large whirlwind collector. The airflow system of the machine is closed and circulates in positive and negative pressure.

In the grinding chamber due to the grinding material has a certain amount of water, grinding heat generated when the grinding chamber gas transpiration changes the amount of gas flow, and the whole pipe connection is not close to the outside gas is sucked, so that the amount of circulating air flow to add, Resulting in the mill powder and even explosive machine, which, the new European version of the ladder-type milling machine is now in the upper part of the body with explosion-proof approach to the maximum limit to prevent Raymond Mill machine explosion caused by accidental damage , Together with this situation can also be adjusted by the fan and the host of the wind between the host to reach the balance of airflow, and the remaining gas into the small whirlwind collector, the residual gas into the fine powder collected, and ultimately from the The upper exhaust pipe of the small whirlwind collector is discharged into the atmosphere or is introduced into the dust collector to purify the exhaust gas. However, the skill requirement of the operator is relatively high, and the demand is found and adjusted in time.
