High-efficiency impact sand making machine

Abstract

The invention relates to a high-efficiency impact sand making machine, comprising a box body, a rotor part, an impact rack, a maintenance hanging bracket and a vibratory feeding hopper, wherein the rotor part is mounted on a lower base of the box body, the impact rack is hung on the top of two inner sides of the box body, the maintenance hanging bracket and the vibratory feeding hopper are mounted on the top of the box body respectively, and a crushing cavity is formed between the impact rack and the rotor. Materials can be subjected to multiple-likelihood continuous impact and crushing in the crushing cavity more than twice, and multiple impact and crushing can be realized between the materials; impact lining board and flat hammer are made of alloy material, thereby prolonging the service time of the high-efficiency impact sand making machine; the high-efficiency impact sand making machine has wide feeding scope, the feeding grain size can reach 80mm; the high-efficiency impact sand making machine has high rotating speed and the linear speed of the rotor can be as high as 80m / s, thus one-step formation rate of the materials is up to more than 60%, and the product can obtain excellent grade; the high-efficiency impact sand making machine has the advantages of being low in weight, large in feeding grain size, strong in processing capability, high in yield, low in energy consumption, simple in operation and convenient in maintenance.

Description

technical field [0001] The invention belongs to the technical field of construction equipment, and relates to a high-efficiency impact sand making machine capable of making sand and crushing fine materials. Background technique [0002] It has long been the consensus of human society to protect, develop and utilize various mineral products as a resource. However, the resource status of sand, which is widely used in infrastructure construction, has not attracted enough attention. With the acceleration of economic construction and social development, the demand for sand is also increasing. Especially in the pouring of concrete dams of various hydropower stations and the construction of high-grade expressways, there are higher requirements for "special sand". In addition, most of the sand used in infrastructure construction comes from river sand, resulting in the phenomenon of indiscriminate mining of river sand in many areas, which brings hidden dangers to flood discharge an...

Problems solved by technology

However, the traditional sand making equipment is bulky in size, low in output, high in energy consumption, inconvenient in maintenance, and requires a narrow range of feed particle sizes.

Rod mill machine-made sand has large investment, low efficiency, and bulky body. For example, the MBS2740 rod mill weighs 75T, the motor power is 400KW, and the production capacity is 80T / H; High cost, such as the PL1250 impact crusher with a machine weight of 21T, a motor power of 400KW, and a production capacity of 65T / H, while a set of alloy wearing parts can only use 50-80H

The feed particle size of the rotary disc cone machine is small, the efficiency is low, and the product particle size is poor

Hammer crusher has low efficiency, fast wear and high production cost
