Mine hoist can be divided into two kinds; one kind is JKE series single rope mining hoist and the other is Multi-rope friction hoist.
This series mine hoist including 2m-5m single tubular and double tubular types, and can be used for mining hoist, personnel lifting and material and equipment descending from vertical shafts or inclined shafts of coal, metal and nonmetal ores.
JK mine hoist is mainly used in inclined roadways and wells of coal mines, metal mines and non-metal mines to hoist or lower personnel and materials.
This machine is mainly used for floating 0-0.5mm beneficiated ore, and dewatering clean coal, waste coal and other fine materials, it also can be used for solid-liquid separation in metallurgy, chemical industry, petroleum and sewage treatment. The acid-proof filter is used for separation of solid-liquid corrosiveness materials, with using stainless steel materials.
Application: Spiral classifier is widely used for grading ore pulp in metal beneficiation flow. It is also used for desliming and dehydrating in washing operation, and usually matched with ball mill in close circuit.
Introduction
CITICHL is one of the largest design and manufacture enterprises for rotary kilns in China, which started producing in 1950s. We have totally produced more than 250sets of rotary kilns including dry, semi-dry and wet ones used widely in cement, metallurgical, chemical industry, refractory, active lime, paper-making etc. Specifications are from Φ1.2 to Φ6.1m. They have been exported to Thailand, Pakistan, Indonesia, Vietnam etc.
Our company has absorbed technologies from famous international companies such as Smidth, Polysius, KHD, etc. In recent years along with the advances in cement producing, cooperated with design institutes in Tianjin, Nanjing etc, developed new large serial products of dry processing rotary cement kilns, matching 1000-5000t/d large and 8000-10000t/d extra-large cement production line. There have been nearly hundred sets put into operation in the cement plants of Anhui, Hailuo, Jilin Shuangyang, Indonesia Kupang etc.
Our company has the first-rate group on rotary kiln development, study and design, perfect experiment and testing measures, and superior manufacturing equipment and technology for large rotary kiln, while has formed the complete technical and producing system on the design, manufacture, installation, commissioning service for the equipment.
Application and operating principle:
The rotary kiln is central equipment for cement clinkering system in the new large dry processing cement production, which can be used with unit-or-twin-stream preheater, calcining combustor. 90%-95% of the raw material which has been pre-calcined feeds into the slow rotating, inclining installed rotary kiln from the rear. Under the composite effect of circumferential tilting and axial movement, the material slowly flows through the whole drum, the fuel (coal dust, oil or natural gas) sprays from kiln head into high temperature zone for burning, which produces the required heat for physical and chemical reaction of combination and crystallization of material inside the kiln. Under the function of rear blower, the burning gas stream and material counter flow the whole kiln, completing heat exchange and physical/chemical reaction. The clinkered cement is discharge to the cooler.
Characteristics:
The kiln body is made of high-quality killed carbon steel or alloy steel plate and welded;
The supporting type and rollers is of ZG35CrMo and 42CrMo steel;
The sliding bearing is of non-scraping liner one with large clearance;
The driving device adopts hard-toothed reducer, flexible sheet coupling, driven by DC motor;
Hydraulic thrust roll is used;
The kiln head and rear seal is of pneumatic or scaled type;
With slow speed drive.
Jaw crusher is widely applied to crush high hardness, mid hardness and soft rocks and ores such as ore quartz, granite, limestone, slags, construction materials, marble and so on. The maximum compression strength of materials to be crushed is 320MPA.PE series is used for primary crushing; PEX series is used for secondary crushing and fine crushing.
Working principle:
The machines leather belt and wheel are driven by the electric motor, then movable jaw begins to move up and down by the eccentric shaft, when the movable jaw moves from top to bottom, the angle between fixed jaw and movable jaw becomes smaller, the movable jaw plate deviates from the fixed jaw plate under the function of dragging rod and spring, at this moment the crushed materials are discharged from the bottom outlet of the crushing cavity.
Hammer crusher is suitable for mid-hardness and brittle materials, such as limestone, coal, gypsum and so on. The maximum compressive strength of the broken materials is no more than 150kg/cm2. It is mainly used in cement, mining, coal mine, chemical, building materials and other fields.
The cone crusher is used for the crushing of raw materials in metallurgy, architecture, road construction, chemistry, and silicate industry which can grind the mid-hard ore and rock. Cone crushers adapt to medium and fine size ore and rock with large crushing ratio, high efficiency, low energy consumption, even particle size.
Introduction: Vibrating feeder can feed lump or granulated materials to the other devices evenly and continuously. In sand and gravel production line, the continuous feeding of the Vibrating feeder helps avoid the blockage at receiving hopper. With easy flow adjustment, low noise and energy consumption, vibrating feeder is applied to crushing and screening production lines on crushing site, in mining, metallurgy, building material, chemistry, mineral processing, and coal industries.
Vibrating feeder consists of vibrating frame, spring, vibrator, motor vibrating device and motor. The vibrator is made of two fixed eccentric shafts whose gears are jogged. When installation, the two gears must be jogged according to the sign. 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, and avoiding the further crushing, so screening purpose can be reached.
