1. This standard is applicable to the wall made by various concrete small hollow block, the main specifications size are 390mm * 190mm * 190 ~ 140mm (length * width * height), and the hollow rate doesn't less than 25%. Henan Daswell Machinery Co., Ltd,is a professional manufacturer and trader specializing in the research, development and production of construction machinery for nearly 30 years. Our main products are as follows:mobile concrete mixer,concrete batching machine,portable batch plants,etc. We will provide you with the best product and service.   2. The test items of this standard include the size and appearance, compressive strength diesel concrete mixer, flexural strength, material density, bulk density, hollow block rate, water content and water absorption rate, dry shrinkage rate, softening coefficient, carbonation resistance, frost resistance and impermeability etc. 3. The test pieces used for the examination project of all performance shall be qualified block in appearance and size.   Aim at a lot of waste resources, rationally use the waste resources SICOMA Planetary Concrete Mixer, improve waste utilization rate, and reduce the production cost are the primary question that each investor should consider. Hollow making brick really do to save energy, reduce the dosage of cement block laying machine, so that the cost of raw materials is reduced by about 36%. The hollow brick product has many functions, such as heat preservation, heat insulation, sound insulation, light weight, and anti seismic. It is widely used in the environmental protection and energy saving type architectural and urban modernization residence. Hollow brick machine equipment is not only advocated by the State, but the builders also very satisfied, because it reduces the building cost, and increase the sales area.
1.belt ingredients formula: Henan Daswell Machinery Co., Ltd,is a professional manufacturer and trader specializing in the research, development and production of construction machinery for nearly 30 years. Our main products are as follows:concrete mixer price,portable cement mixer,small concrete mixer,etc. We will provide you with the best product and service.   Its structure is mostly the upper part of the raw material storage hopper, the lower part of the hopper bottom discharge conveyor belt, the storage hopper for storage to be with the raw materials Readymix Concrete batching plant, the end of the hopper mouth Founder ingredients conveyor belt. The principle: start with the ingredients start, belt conveyor belt to stop the raw materials to the settings in the storage hopper, and then under the control of the control instruments, followed by the configuration of the next several materials, all materials configured instrument control to start the discharge belt material into the next link (such as upgrading the concrete mixer bucket or belt conveyor, etc.). 2.cylinder ingredient batching machine   Its structure is mostly the upper part of the raw material storage hopper heightening board set to increase the capacity of the material storage and more MP500 Planetary Concrete Mixer, the lower hopper: all the ingredients under the door can be equipped with an overall measurement of the Big Dipper, so that each material in turn matches into the same hopper, but also in each ingredient under the door to set up a separate measurement of the Big Dipper, the completion of the measurement of material from the bottom of the belt conveyor into the next link.
