Core Hole Drilling is a drilling technique whereby an oil or gas well is drilled either in a vertical hole or horizontal hole. The method used to drill a vertical hole is known as vertical drilling whereas for a horizontally drilled hole is known as horizontal drilling.
The core drill rig of full hydraulic and rotor adopted the technology of wire-line coring has been the dominant type rig for solid mineral deposits prospecting in developed counties of the world. The rig is light, simple in structure, and easy for transportation. The mast has the functions of sliding and touching ground, the spindle lifted and lowered with hydraulic cylinder. It could be folded for transport and relocation. The spindle hole is in large diameter.
It is a thoroughly new-type wire-line Core Drilling Rig developed on the basis of the market demand and the advanced techniques in the world. It is mainly used for metal&nonmetal solid exploration and exploration of coal-bed methane, nature gas mining, hydrogeology well drilling, geothermal well drilling, mining gallery, ventilation and drainage of exploratory and emergency construction projects.
In most cases, it can drill into stratums with depths of more than 350 meters and more than 500 meters and can be widely used in core drilling work with extremely complex ground conditions.
It is ideal equipment for deep-hole geological exploration drilling. Contact us to get a cheap YK core drilling machine price. Ores Prospecting and Lab Experiment,underground prospecting,geological investigation Henan YK Prospecting Machinery Co., Ltd , https://www.yyundergrounddrillingrig.com
                         chinese herbal medicine grinder
1. Main Application
(1) The machine is applied in industries such as pharmaceutics, foodstuff, chemicals and etc, with features of cool air and no sieve or screen.
(2) It is not limited by the viscosity, hardness, softness or fiber shape of the raw materials, and has good effect to all materials, especially to those Chinese herbal medicines with fibers and those with oils.
2. Working Method:
The machine is composed of feeder, grading wheel, pulverizing blades, gears, pulverizing motor, discharging gate, fans, collection box, dust collection box and etc.Â
Any raw material, being feed into the grind chamber through the upper feeder,is pulverized by high speed running blades.Â
The fineness of the finished products is regulated via the distance adjustment of grading wheel and grading plate.Â
The high speed running fans will lead those pulverized material from grinding chamber to discharge gate via negative pressure while whose unpulverizer remained in the chamber.Â
The dust from grinding is filtered and recycled via the cloth bag or filter of the dust absorption box.Â
3. Feature:
The whole machine, designed according to GMP standard, ismade of stainless steel, with the features of easy structure, convenient operation and cleaning, low noise and high capacity, avoiding dust flying in prouction.Â
