Raymond mill is a common industrial powder equipment,and it's used to grind barite, limestone, ceramics, etc, such non-inflammable and non-explosive stuff,which the hardness is below 9.3 Mohs and moisture is less than 6% in the trades of mining,metallurgy,chemical engineering and construction material.The fineness size is adjustable in the range of 60-1250 mesh(It can even reach to 2500 mesh).It is possible to produce 10-60 mesh powder through assembling special device in the machine.
According to Raymond mill operating principle and working practice, we found that the main influence factors of Raymond mill's output mainly include:
1. One of the factors that affect the raymond mill's output:The hardness of the materials.The more hard the material,the more difficult to grind for the Raymond mill,and the more serious to wear for the equipment.The speed of the Raymond mill slow, of course,,the capacity of the Raymond mill is small.We recommend that customers use the equipment in daily process,should be strictly in accordance with the use of the Raymond mill's operating rules,don't use the equipment to crush the mateials that exceed the Raymond mill's ability.It's also the basic point of Raymond mill's use and maintenance daily.
2.The second factor that affect the raymond mill's output:The humidity of the materials,that is, if the raw materials contain water higher,the materials will easily adhere onto the Raymond mill, easily plug when the course of the materials being conveyed,so that causing the output of Raymond mill reduce.
3.The third factor that affect the raymond mill's output:The output size.The required size is high,that is the output size is smaller,the capacity is lower.If the customers have a high required of the materials’size,can according to their own production capacity and economic strength for other devices,such as YGM series High pressure micronizer.This machine have a wide range of product size,the smallest can reach to 2500 mesh.
4.The fourth factor that affect the raymond mill's output:the composition of material. If there is much powder in the raw material, it may reduce down the capacity. Because the powder will be easily to adhere.For this materials should be screened once in advance. For this situation, we recommend that customers should sieve the materials with the vibrating screen before the milling process.
5.The fifth factor that affect the raymond mill's output:The viscosity of materials.That is, the larger viscosity, it is easier to be adhesion.
6.The sixth factor that affect the raymond mill's output: The quality of quick wear parts (such as hammer,jaw plate). If the quick wear parts has no good wearlessness, it will reduce down capacity.
In short, there are many factors that effect the Raymond mill's outputand some are for the use of customer,for these factors,we have to continuously summarize,and timely evade,of course,there are some technical factors of the equipment itself.For these,it should be judged by themselves to make a right choice.

Jaw crushers are typically used as primary crushers, or the first step in the process of reducing rock, are one of the main types of primary crushers in a mine or ore processing plant. The size of a jaw crusher is designated by the rectangular or square opening at the top of the jaws (feed opening).They crush primarily by using compression,is widely used in mining, metallurgy, construction, highway, railroad, and chemistry industries.

Jaw crusher work principle:

The motor transmits power through belt, drives the moving jaw do periodic motion to the fixed jaw surround the eccentric shaft. The angle between toggle plate and moving jaw increases when moving jaw moves up. So the moving jaw closes to the fixed jaw. The stuff will be crushed in this process. The angle of Jaw Crusher between toggle plate and moving jaw decreases when moving jaw moves down, the moving jaw of Jaw Crusher moves away from fixed jaw by the pulling of rod and spring, the products after crushing will be discharged from the outlet of Jaw Crusher.

5. Our vibrating feeder is added closed frame, it can largely reduce pollution and noise.

Vibrating Feeder working principle

Vibrating feeder working principle as follows:
Through drive of the motor, the two eccentric shafts start rotating to produce a linear huge power which forces the feeder to vibrate. Through the vibration, The materials will slip and sling on the funnel, moving forward, when the materials pass the screening part, smaller parts will fall down, avoiding the further crushing, so screening purpose of vibrating feeder can be reached.

raymond mill:
Comparing with ball mill, raymond mill features high efficiency, low power consumption, small size, a one-time small investment and widely used in barite, calcite, potash feldspar, talcum, marble, limestone, dolomite, fluorite, lime, activated clay, activated carbon, bentonite, kaolin, cement, phosphate rock, gypsum, glass, insulation materials, etc whose mohs hardness is not greater than 9.3 and humidity is below 6%. Raymond Mill is mainly consist of the milling system, analysis system and dust removal system.
Installation:
Pre-installation preparation :
1. Before Raymond mill has not yet installed on site, should be properly kept.
