Shandong Hongda

We Offer trailer concrete pump. HONGDA S-valve series of high-pressure pumps, Z-gate-valve series of medium-pressure pumps and D-butterfly-valve series of low-pressure pumps are concrete transport machines widely used for the construction works in city construction, bridge construction, electric power and other energy source facilities and so on. The machines adopt world-level advanced technologies such as open hydraulic loop, distributing valve auto-compensation clearance, constant power control, all-hydraulic automatic reverse and electric proportional control. The company has carried out in-depth and meticulous studies and experiments in many aspects like the self-lubrication of concrete pistons and has obtained many patents. The HONGDA trailer pump is a world-level new product which is developed on the basis of combining latest domestic and overseas technologies. HONGDA trailer pumps cover three series and more than twenty models, so HONGDA is a professional production base with all models and specifications of trailer pumps in CHINA, which can fully meet the various needs of all customers. All HONGDA trailer pumps are assembled through streamlined production. The company strictly controls all the machining processes and the assembly quality, giving final test to every trailer pump through simulated working conditions and overload experiments to ensure zero fault in customers the first operation.

We Offer Asphalt Mixing Plant.I. Main Features: 1. The original modular design of the mixing plant makes transport and installation work quick and convenient. It can separate extra-large flotsam from usable stuff.2. The loop belt feeder for the measuring hopper has a frequency-conversion speed regulator which can provide high and low speed. Its original structure facilitates belt change and makes material feeding more fluent, which reduces power consumption. Besides, there is a warning light which will remind the user when the machine uses up raw material. 3. The high-efficiency and heat-preservation drying drum and the special vanes make heat exchange more sufficient. Moreover, the high-efficiency and energy-saving imported burner can use both heavy oil and diesel, which reduces energy consumption.4. The vibrating screen adopts the linear and completely-closed design with the vibrator placed outside. The sieving efficiency is high, the maintenance and changing of screen is easy, and the imported bearings are more reliable. 5. The hot aggregate bin is equipped with a continuous level indicator which enables the operator to know the level of material at a glance. The measurement of aggregate is conducted twice through large and small doors, which greatly improves the measuring precision. The unique structure of the material emptying door reduces the chance of blockage and will work more reliably. 6. The main mixing machine designed with European technology has double reducers with a high-speed synchronization capacity. Accurately-weighed asphalt can be directly pumped into the agitating kettle and powder material can be conveyed into the agitating kettle through the helix, which makes agitating more even and speedy. Besides, it has an opening to add wood fiber and an inlet to add used material to be recycled. 7. The dust-removing system adopts imported NOMEX bags which limit the density of dust
