We are offering zjk70/60-4.0 double stage vacuum extruder. Product description:"mengda brand"series double stage vacuum extruder is the new brick making equipment designs and manufactured by our factory through several researches and use of domestic and international advanced experience, they are mainly used of the new material of coal gangue, coal ash, shale , clay and so on.it is the ideal equipments for the production of various hollow brick, shale, coal gangue and coal ash. jzk70 vacuum extruder is introduced from foreign countries.the performance of the speed reducer of the extruder is improved.the forming moisture of the bricks is 16%-18% so the bricks are easy to bake. This type of vacuum extruder can meet the requirements of large production capacity and easy to operate. product advantages:the main frames of the vacuum extruder machine are welded by using high-quality steel and have the feature of :1. Low cost, reliable performance, rational structure, solid and durable properties. 2. Strong adaptability, easy to operate, low energy consumption, high capacity, long service life and easy to maintain and so on.

We are offering double shaft mixer. product decription: the mixer adds water to brick-making raw materials after crushing processing, and then mix, blend and homogenize, which can further enhance the comprehensive plastic index of raw materials, and the greatly improve appearance quality and yield rate of brick and tile , thus it is the indispensable raw material processing equipment for brick and tile enterprise, it is mainly used for watering and mixing treatment for clay, shale, coal gangue, coal ash, and other raw material.

We offer roller screen. The trommel main motor, reducer, roller device, rack, closures, out of the discharge port. The inclination of the drum unit is installed in the rack. Motor through a gear unit and the drum means is connected via a coupling with the drive roller means is rotated about its axis. When the material into the drum assembly, since the inclination and rotation of the drum assembly, so that the flip and scroll of the screen surface material (the undersize product) is discharged by the trailing edge of the drum at the bottom of the spout, so that qualified materials, conforming material (sieve on the product) is discharged through the discharge opening of the drum tail. As the material within the drum of the flip, scroll, so that the card can be ejected, to prevent the sieve clogged sieve materials. The trommel sand drum screening machine drum sieve structure is almost the same principle, people know it and it is called there are differences. trommel adaptation: 1.a quarry for large pebbles grade. Isolated from soil and stone powder. 2.sand field with sand separation. 3.coal industry for the separation of lump coal and coal as well as an integral part of the coal washing (coal washing machinery)4.chemical industry, mineral processing industry for size the lumps classification and separation powdery substance. advantage: 1. The screen is not easy plugging holes2. Simple structure, smooth operation, low noise3.less investment, high reliability and easy repair and maintenance, long service life4.high screening efficiency, using a variety of different materials, wear-resistant mesh (mesh material can choose manganese steel, stainless steel, etc.) the use of features: 1.high efficiency, can be achieved between 2-80mm material screening, while 1-5 grade material screening2.according to the needs of the materials screening, be replaced at any size sieve mesh of a machine3.small size, low power.

We are offering double screen end mill.It is used in the fine crushing before the raw materials entering into the grinder in mines and cement plants, the basic principle of "more crushing, less grinding "is reflected, function of fine crushing is brought into fully playing to enhance the processing capacity of grinders, electricity consumption and steel ball consumption are reduced, volume of production of grinders is greatly increased.Used in the brick making enterprises that are using coal gangue and shale to produce new type wall materials, the problems of raw materials with high moisture troubling normal production of brickyard is solved, the particle grading is reasonable, particularly suitable for production of perforated brick and thin brick.The crusher is equivalent to two sets of hammer crusher and combined into a whole one reasonably, cascaded using of two sets of rotors without screen, has the ollowing characteristics:i.dual rotor crushing in up and down two-stagetwo sets of cascade rotors make the materials crushed by up stage rotor hammer be fine crushed by the rotary down rotor hammer, materials in the inner space ollide with each other reversely and smash one another, the effect of hammer crushes materials and materials crush materials is achieved, and they can be unloaded directly.Ii.no screen, no blocking for materials with high moisture contentthe traditional crushers with grate sieve plate can not meet the raw materials with the moisture content higher than 8%, serious blocking will occur if the moisture content of raw materials is higher than 10%, and the hammer can not rotate and materials can not be discharged, even the motor will be burned out and effect the production.The design of the crusher is without screen, it has no strict requirements on moisture content of raw materials, the problem of blocking on the sieve plate is absent, and troubles that fine powers can not be discharged in time and repeated grinding do not exist either, so the grinding efficiency is high, and invalid abrasion of hammer does not exist.Iii.unique bidirectional gap adjustment technologygranularity will coarsen and the gap between abraded hammer and liner plate largens after the hammer consuming, it is proper to move the position of hammer from the center to the outside to reduce the gap with liner plate and to continue to use. It is also allowable to push the liner plate outside-in to regulate the gap and control the granularity of discharged materials.Iv.equipped with balance wheel giving steady rotation and high inertia, saving electricity for 20%ends of two sets of rotor spindle up and down are equipped with flywheels, which can regulate the periodical speed fluctuation of operation, and make operation uniform and steady, increase rotational inertia and overcome resistance to motion, it can save the electricity for more than 20%.V.centralized lubrication system, oiling without machine halt, conveniently and efficientlylubrication system of two-stage crusher changes the traditional lubricating oil injection method of grease mouth and grease cup; the centralized oil feeding equipped proportioning pump has one step of operation and can supply oil for multi-way; the complete machine can injects lubricating oil synchronously to all bearings under working position, which is convenient and efficient, it can also prevent intrusion of dust damaging the bearings.Vi.hydraulic pressure starting case
