All types of ore, apatite disseminated particle size ranging typically between 0.2 ~ 0.04mm. The ore content generally has a moisture content of about 6%. The natural repose angle of ore varies with grain size, moisture content and ore type, generally 45°~60°; the natural rest angle of ore containing high muddy water is about 80°. The ore density is 2.8 t/m 3 and the bulk density is 1.6 t/m 3 . Because the ore is subject to different degrees of weathering and leaching, the Platts hardness is mostly 4-6. (3) The technical improvement since the plant was put into production has the following aspects: the original design of the crushing process is a three-stage open circuit, and the muddy plugging is changed to a two-stage open circuit; the improvement of the medium crusher cone causes the parallel zone of the crushing cavity to grow by 80 mm. The particle size of the crushed product is reduced from 65mm to less than 50mm, the ball mill combined feeder is eliminated, and the inclination of the classifier installation is increased to 19°, so that the grinding grade reduces the power consumption and steel consumption; the flotation inhibitor is changed from starch to water. Glass; the collector is changed from soybean oil fatty acid to crude sulphated soap; the normal temperature flotation is changed to the slurry heating flotation; the low concentration flotation is changed to the high concentration flotation; the concentrate dehydration is replaced by the outer filter to the internal filter . As a result of the above improvements, the water and electricity consumption indicators of the plant are the lowest compared with the black, nonferrous and chemical industries. our rescue golf carts with 2 seats that enquip the bed for the patient or the injured personos, it is very practial for the emergency situation,come with 4 kw DC or 5KW ac motor,its max speed is around 30km/h and max climbing ability up to 35 degree when full peoples loaded, the bed is easily to take out and fix on and carts ready to go everytime, come with high capacity deep cycle storage battery sets, its max range up to 90kms per charge that enough for rutine day time use, its width is 1.2m that is capable for most of the road situation and inside area, our rescue golf carts are widely used for many hospitals all over the world and enjoying the postive feedbacks, our cop&patrol golf cart come with the top LED flash lights that mainly for patrol and police officer,we have 2 4 and 6 seat for your choice,the extra feature recommended would be the rain cover,sunshade,,etc, our cop golf carts can made with your own lable or logos,its max range is around 90kms per charge,we can make the range up to 120kms by using a bigger capacity battery should you need this.
